Hamilton Island Race Week: Audi's Joerg Hofmann presents Viva La

At the Audi Hamilton Island Race Week official prize giving last evening Joerg Hofmann, Audi's managing director, announced that Viva La Vita, owned and skippered by Tony Bates, had been declared the winner of the Audi A4 Avant. Bates was the lucky recipient after being declared winner of the Cruising Division 2 following the final race yesterday, and winning the Audi Drive Challenge held earlier in the week for all competing yachts at the Hamilton Island Airport. While each entry at Race Week had the opportunity to contest the Audi Drive Challenge, only the winners of each division were eligible to win the A4 Avant. On announcing the winner, Mr Hofmann said: "rather than focus on speed, competitors had to drive accurately and consistently during two time trials."  Mr Hofmann continued: "I am very pleased to announce this particular winner.  I was at the Audi Sydney Harbour Regatta in March and he told me he did not drive his car to the final day of that event because he was convinced he was going to win a car!" Bates and his crew from Middle Harbour Yacht Club were thrilled with the major prize. On accepting the keys to his new car, Bates said: "Three of my crew are already driving Audis, so you can see that Audi's sponsorship of sailing has already had an influence. "I'm delighted to win the A4 Avant.  I'm thrilled.  I'd like to thank everyone for a great Race Week; Audi, the Oatley family and all the competitors.  It's been a fantastic regatta."    Other awards were handed out last evening.  The 10-year award, open to yachts that had contested a minimum 10 Race Week's went to Mike Davies (Sandstone), while Best Northern Queensland Boat went to Scaramouche (Graham Smith).  The Prix d' elegance special commendation went to Holy Cow (John and Kim Clinton) and You're Hired (Geoff Morgan and Andrew Banks) won the Prix d' elegance Trophy. Audi Hamilton Island Race Week overall winner, Geoff Ross (Yendys), also won the Boat of the Week award.  Speaking of both wins, Ross, from the Cruising Yacht Club of Australia in Sydney, said:  "This is a great regatta and I have a great bunch of dedicated guys who work terribly hard to get the results we do – my crew. Last night's prizegiving ceremony, hosted by celebrity comedian, Vince Sorrenti, signalled the end of a 219 entry record breaking Audi Hamilton Island Race Week. Island owner, Bob Oatley, told competitors:  "What a week we've had.  Congratulations to Joerg Hofmann and his Audi team; what a job they've done.  Their contribution at Hamilton Island has been great; they've put new life into yachting.  Audi and sailing are very compatible and it's been great to see so many Audis on the Island." Mr. Oatley went on to thank supporting sponsors, UBS and Club Marine.  He also thanked Hamilton Island staff for the effort they had put in to making the week a success. Commodore of the Great Barrier Reef Yacht Club on Hamilton Island and Olympic campaigner for the Australian  Sailing Team (of which Audi is a major sponsor) Iain Murray also attended the prizegiving.   Murray has just returned from the Beijing Olympic test event in Qingdao where he and Andrew Palfrey finished 11th in the Star keelboat. "We're blessed to have places like Hamilton Island to sail at, and great supporters." "Their  (Audi's) sponsorship really has shown – in this room, in the racing and down to the main street," said Murray, who concluded by telling assembled guests that Hamilton Island's new yacht club would be well underway by the time we all returned next August.

Executive cars of the year: Audi A6, Audi A8

The Audi A8 has been voted as "Executive car of the year" again, for the third time in a row. Now the Audi A6 also claims that title.n the executive rankings of German business magazine Impulse, Audi is once again the most successful brand. The Audi A8 in the luxury class and the Audi A6 in the upper mid-size class received most votes from Germany's senior executives in their respective categories. The Audi A8 topped the survey for the third time in a row. With its outstanding comfort, superior quality and handling characteristics it convincingly beat off the competition. But just being good is not good enough for Audi. The luxury saloon has just been substantially updated and now offers further enhanced running smoothness and ride comfort, for example. Impulse readers also voted the Audi A6 their favourite in the "upper mid-size" class. Both the saloon and the Avant are very popular among senior executives. In the other two categories, Audi models were among the leaders, too. In the "sports car" section the Audi R8 took second place at its first attempt, despite being on the market for only a few months. Also in second place was the Audi Q7 in the "SUV" class.

2009 Audi A2

Lower emission and higher fuel efficiency, well automaker could escape it due to tough regulations not only in US but throughout the world. Europeans measure it with CO2 emissions rather than fuel economy. This adds another worry for automakers. 1999 Audi A2 was also fuel efficient premium small car but was not as successful as the car was a bit expensive.

Audi is also feeling the pressure and is going ahead with smaller, more fuel-efficient cars. 2009 Audi A2 subcompact car will be inline with these tough regulations.
2009 Audi A2 will be using the VW subcompact underpinnings with gasoline engines ranging from 1.2 to 1.8 liters and diesels. Future Audi A2 will most probably feature Quattro AWD along with an optional turbocharger.

Audi A2 will be built at the Brussels Belgium plant that Audi recently took over.

Audi’s RS6 will get more than 571hp

We recently reported that leaked vehicle chassis codes for the new Audi RS6 specced the output from its twin-turbo V10 engine at 571hp (426kW). Recent information from a source at Audi, however, has put this figure in doubt. The reliable source claims that the 571hp will only be the specified figure Audi will market the car with. True output will be upwards of 600hp, with 610hp (455kW) pegged as the most likely figure. It looks like Audi is taking no chances with the ultimate "wolf in sheep's clothing" model and even BMW's excellent V10 motor will struggle to compete with this kind of power output.

To give you an idea of just how high this figure is, the RS6 will churn out more horses than the Corvette Z06, BMW M6, Lamborghini Gallardo Superleggera, Ferrari F430 Scuderia, Aston Martin DBS, Porsche 911 GT2, and even Mercedes' epic bi-turbo V12 CL65 AMG.

While we're always happy to see manufacturers pushing the limit, surely there comes a time when outright power figures get out of control. The previous RS6 wasn't a slow car by any stretch of the imagination, but the new model will likely become the most practical supercar ever made. At least owners will have a full-time AWD system to help keep them out of trouble.

Audi R10s lose a heartbreaker in Mosport

First the good news for Audi Sports North America. The No. 7 R10 won the LMP1 class during last weekend's 9th Round of the American LeMans Series race at Mosport. With the win, Audi has clinched the LMP1 championship with three races left to run. Unfortunately, Audi has yet again failed to claim an outright win despite dominating the entire race ahead of those pesky LMP2 cars.

The Audi driven by Alan McNish had inherited the lead late in the race when Timo Bernhard pitted his LMPS Penske Motorsports Porsche RS Spyder. Things were going well, with the McNish building a comfortable 22-second lead. Unfortunately, the R10 then experienced some kind of gearbox malfunction with ten minutes to go that left McNish with only the higher gears. Every tight corner of the track gave Bernhard another opportunity to close the gap. Bernhard caught McNish with about five minutes left to go, and went on to build a 19.575-second lead.

Audi looks to electronic driver trainers to save fuel

At its recent TechDay 2007 seminar in Germany, Audi talked up a new system under development that'll analyze driver behavior and give fuel saving driving tips to help curb fuel consumption. Some of the initiatives include plans for a satnav system that records "consumption-relevant data" as well as the previously mentioned electronic driver trainer that will be "able to analyze the current driving style and give tips accordingly."
Audi wants to emphasize the point that individual driving styles can dramatically affect fuel-consumption levels, mentioning that it's possible to reduce consumption by up to 30% without having to compromise "speed and dynamism." Officials also revealed that they expect the conventional combustion engine to remain for years to come, despite advances in hybrid and alternative fuel powered vehicles.
Other technologies the carmaker talked about include new TFSI engines that can run on compressed natural gas as well as its new 'Modular Efficiency' program. This latter feature is similar to BMW's EfficientDynamics technology and works by restoring energy from braking to create electric energy to relieve the load on the alternator and thus save fuel.Related PostsAudi A3 cabriolet, coming soon to a cafe near youUpdated BMW 3-series next in line to get Brake Energy Regeneration techNew Audi A1 could save Brussels plantSpy Shots: V10 turbo Audi RS6New engines for Audi A5 Coupe

Audi provides some details on the Q7 hybrid

At the 2007 TechDay this week, Audi's Jörg Kerner provided some details on their upcoming Q7 Hybrid. The Q7 shares a platform with the VW Touareg and the Porsche Cayenne. Both of those will offer hybrid versions but it's not clear if those vehicles will use the same system (although the VW almost certainly will). The hybrid SUV will combine VW's 280hp direct injected 3.6L gas V-6 with a 34kW/285Nm electric motor. The motor will be packaged between the engine and torque converter for a strong parallel hybrid setup.

Like the GM Two-Mode hybrids, the air conditioning compressor is now electrically driven to allow A/C to remain functional during electric drive. The power steering pump and vacuum pump for brake assist are also electrically driven. One item of interest is that the nickel metal hydride battery pack only weighs 151 lbs which seems very light. Unfortunately, the same can't be said about the rest of the vehicle which comes in at almost 5,500 lbs empty.

The Q7 can operate in EV mode at low speeds for up to 1.2 miles and the engine can shut down when coasting at speeds up to 75mph. Overall fuel consumption should be reduced by twenty-three percent compared to a standard 3.6L Q7 going from 18.5mpg to 23.8mpg on the EU combined cycle. Carbon dioxide emissions drop from 304 g/km to 231 g/km. That still way above the proposed EU limit of 130 g/km but there's only so much you can do with a nearly three-ton SUV. The text of the presentation is after the jump.

Audi possesses a wealth of experience in the field of hybrid drives – the brand with the four rings began developing hybrid cars as early as 1989. Today, the development engineers' concentrated know-how can be seen in the Audi Q7 hybrid.

The concept of the Audi Q7 hybrid is a full hybrid vehicle in parallel configuration – a concept that Audi has been pursuing for many years. This principle, in which all major assemblies are linearly situated, has great benefits compared to a series configuration, such as the concepts used by the competition. There, the complex system of electric motor, separate alternator and planetary gears has drawbacks not only in terms of weight, but also in terms of energy loss. Functions such as "sailing" (coasting without power), which parallel hybrids are able to realise, are not possible with series hybrids. In certain situations the electric motor actually has to build up braking force to regulate the driving current.

Audi's hybrid drive uses a 3.6 litre FSI V6 with an output of 206 kW (280 bhp) and a peak torque of 375 Nm. An electric motor situated in the drive train adds up to 285 Nm of additional torque. It is a matter of honour for such a supremely powered Audi to be equipped with quattro four-wheel drive, which permanently ensures a maximum of driving dynamics and road safety. Power is transmitted via a six-speed tiptronic gearbox.

The driving performance of the Audi Q7 hybrid is equal to that of a sports car. From standstill, 100 km/h is reached in just 7.6 seconds. And the pulling power is even more impressive. In fifth gear, the large SUV powers its way from 60 to 120 km/h in just 11.9 seconds. In normal driving conditions, the Audi Q7 hybrid, weighing 2,480 kg unladen, consumes on average 9.8 litres of fuel for 100 kilometres. That is 23 percent less than the basic model. The efficiency of the Audi hybrid drive can hardly be demonstrated more convincingly.

Under the bonnet, the 3.6 litre six-cylinder engine is no different from a standard engine. It is equipped with the highly efficient FSI petrol direct injection system. This enables it to develop more output and dynamism than a conventional engine with manifold injection. The V6 is characterised by a beefy torque curve right up to the rated speed, agile response and economical fuel consumption.

A number of modifications in the periphery were necessary for the 3.6 FSI to be used on the Audi Q7 hybrid. The A/C compressor, the oil pumps for the power steering and automatic gearbox and the vacuum pump for the brake booster are all electrically driven. This makes their operation independent of the combustion engine. The new electrohydraulic power steering has the advantage that it needs almost 90 percent less fuel than a conventional system. The vehicle electrical system receives its 3 kW of power from the drive battery via a voltage transformer.

The electric motor, which generates 285 Nm and 34 kW, has a diameter of 330 millimetres and a length of 55 mm. It is located between the V6 and the torque converter of the automatic gearbox. This configuration ensures maximum economy when it comes to space, allowing the complete space in the passenger cell to be used without restriction.

The challenge of transition

A separating clutch links the three-phase synchronous motor with the engine. This makes it possible to drive the car with either of the power plants or with both together. Concentrated know-how can be found in its control system. Within very short periods of time, this has to switch two powerful power plants on, off and together without these operations being noticed. This was resolved by briefly increasing the torque of the electric motor and opening the torque converter lockup clutch.

Like the standard basic vehicle, the Audi Q7 hybrid also has space for three rows of seats and a large luggage compartment. The battery system that supplies energy to the electric motor has a power capacity of 38 kW and is located in the spare wheel recess at the rear of the vehicle.

The nickel metal hydride (NiMH) battery measures 347 x 633 x 291 millimetres and is made up of 240 cells. Each of these works with 1.2 volts, giving a total voltage of 288 volts. Fully charged, the battery is able to store 1.7 kWh of energy. A fan ventilates it with cooled air from the vehicle interior to make sure that it remains in the optimal temperature range.

Compared to earlier generations of hybrid vehicles, the electric motor and the battery are extremely lightweight. The battery weighs 69 kg and the hybrid module with the electric motor 40 kg.

Complex control electronics coordinate the two power plants. These primarily react to the current speed and the commands given by the driver, which the system receives via the accelerator and brake pedals or the tiptronic selector lever. Other important parameters are the charge state of the battery and information received from the wheel sensors, which supply the electronic stabilisation system (ESP) with information about brake operations and the current driving situation.

The electronics autonomously decide about the mutual interaction between the drive components, and implement the driver's commands in a perfect balance of sportiness and efficiency. A menu in the display of the Audi MMI (multi media interface) shows the current operating status.

Separate or combined forces

Fundamentally, three driving modes are possible. The FSI and the electric motor can each work on their own as the drive unit, or the vehicle can combine the power of the two for acceleration. In this mode, the petrol engine is responsible for basic operation, whereby it also needs to supply energy to the battery.

The electric motor on the other hand can be used for speeds up to 50 km/h – i.e. in city traffic – alone and almost inaudible. This can considerably reduce exhaust and noise emissions in built up areas.

The capacity of the battery allows the vehicle to be driven up to two kilometres on purely electrical power – coasting and braking feed additional energy into the system. When the capacity limit of the battery has been reached, the combustion engine is activated to recharge the battery.

The output of 206 kW / 280 bhp and the torque of 375 Nm that the 3.6-litre FSI engine develops are enough to accelerate the standard Audi Q7 from 0 to 100 km/h in 9.3 seconds. If the driver wants to accelerate even faster, the electronics also activate the electric motor to make use of the decisive advantage that the electric motor has: Its torque, unlike the combustion engine, is available as soon as it pulls away.

More fun accelerating

In practice, this torque boost provides a new dimension to acceleration, especially in the lower speed range. Over the first four metres, the Audi Q7 hybrid leaves its opposite number with the V6 petrol engine a full metre behind. In the sprint from nought to 100 km/h, the "boost" from the electric motor gives it a lead of 1.7 seconds.

And when it comes to pulling power, important when overtaking, the additional drive gives impressive assistance. The "boost" is of course automatic and cuts in as soon as the driver depresses the accelerator pedal beyond a certain, slight resistance. The necessary current comes from the battery in the rear.

But the electric motor can do more than just provide extra power. It is also able to feed kinetic energy back into the system and so recharge the battery when the vehicle is braked or coasting. During this operation, known as recuperation, the motor reverses its function in a flash to become an alternator.

Most energy is recuperated when the Audi Q7 hybrid is decelerated from low speed (under 60 km/h) with a rate of deceleration of about 3 m/s2 – a situation that is frequently encountered in city traffic.

The driver notices this no more than he notices another function that also helps to make the new drive system so efficient. If the Audi Q7 hybrid is coasting without the accelerator pedal being depressed, the combustion engine is switched off – this "sailing" is possible at speeds up to 120 km/h.

The six-cylinder engine is also switched off if the vehicle remains stationary for more than three seconds. To continue the journey, all the driver has to do is to remove his foot from the brake and to depress the accelerator pedal again. The engine resumes service immediately. The powerful electric motor will then play the part of the starter motor. This makes it possible to start particularly fast and yet quietly and comfortably.

The intelligent energy management system uses these strategies to achieve a high degree of efficiency in the drive system, making sure that the battery is not overloaded. The hybrid vehicle is able to demonstrate its potential for saving most effectively in city traffic. With an average mileage of 20,000 km per year, the Audi Q7 hybrid recuperates about 720 kWh of energy a year – approximately a sixth of what a four-person household uses.

The driving performance of the Audi Q7 hybrid is equal to that of a sports car. From standstill, 100 km/h is reached in just 7.6 seconds. And the pulling power is even more impressive. In fifth gear, the large SUV powers its way from 60 to 120 km/h in just 11.9 seconds. In normal driving conditions, the Audi Q7 hybrid, weighing 2,480 kg unladen, consumes on average 9.8 litres of fuel for 100 kilometres. That is 23 percent less than the basic model. The efficiency of the Audi hybrid drive can hardly be demonstrated more convincingly.

Under the bonnet, the 3.6 litre six-cylinder engine is no different from a standard engine. It is equipped with the highly efficient FSI petrol direct injection system. This enables it to develop more output and dynamism than a conventional engine with manifold injection. The V6 is characterised by a beefy torque curve right up to the rated speed, agile response and economical fuel consumption.

A number of modifications in the periphery were necessary for the 3.6 FSI to be used on the Audi Q7 hybrid. The A/C compressor, the oil pumps for the power steering and automatic gearbox and the vacuum pump for the brake booster are all electrically driven. This makes their operation independent of the combustion engine. The new electrohydraulic power steering has the advantage that it needs almost 90 percent less fuel than a conventional system. The vehicle electrical system receives its 3 kW of power from the drive battery via a voltage transformer.

The electric motor, which generates 285 Nm and 34 kW, has a diameter of 330 millimetres and a length of 55 mm. It is located between the V6 and the torque converter of the automatic gearbox. This configuration ensures maximum economy when it comes to space, allowing the complete space in the passenger cell to be used without restriction.

The challenge of transition

A separating clutch links the three-phase synchronous motor with the engine. This makes it possible to drive the car with either of the power plants or with both together. Concentrated know-how can be found in its control system. Within very short periods of time, this has to switch two powerful power plants on, off and together without these operations being noticed. This was resolved by briefly increasing the torque of the electric motor and opening the torque converter lockup clutch.

Like the standard basic vehicle, the Audi Q7 hybrid also has space for three rows of seats and a large luggage compartment. The battery system that supplies energy to the electric motor has a power capacity of 38 kW and is located in the spare wheel recess at the rear of the vehicle.

The nickel metal hydride (NiMH) battery measures 347 x 633 x 291 millimetres and is made up of 240 cells. Each of these works with 1.2 volts, giving a total voltage of 288 volts. Fully charged, the battery is able to store 1.7 kWh of energy. A fan ventilates it with cooled air from the vehicle interior to make sure that it remains in the optimal temperature range.

Compared to earlier generations of hybrid vehicles, the electric motor and the battery are extremely lightweight. The battery weighs 69 kg and the hybrid module with the electric motor 40 kg.

Complex control electronics coordinate the two power plants. These primarily react to the current speed and the commands given by the driver, which the system receives via the accelerator and brake pedals or the tiptronic selector lever. Other important parameters are the charge state of the battery and information received from the wheel sensors, which supply the electronic stabilisation system (ESP) with information about brake operations and the current driving situation.

The electronics autonomously decide about the mutual interaction between the drive components, and implement the driver's commands in a perfect balance of sportiness and efficiency. A menu in the display of the Audi MMI (multi media interface) shows the current operating status.

Separate or combined forces

Fundamentally, three driving modes are possible. The FSI and the electric motor can each work on their own as the drive unit, or the vehicle can combine the power of the two for acceleration. In this mode, the petrol engine is responsible for basic operation, whereby it also needs to supply energy to the battery.

The electric motor on the other hand can be used for speeds up to 50 km/h – i.e. in city traffic – alone and almost inaudible. This can considerably reduce exhaust and noise emissions in built up areas.

The capacity of the battery allows the vehicle to be driven up to two kilometres on purely electrical power – coasting and braking feed additional energy into the system. When the capacity limit of the battery has been reached, the combustion engine is activated to recharge the battery.

The output of 206 kW / 280 bhp and the torque of 375 Nm that the 3.6-litre FSI engine develops are enough to accelerate the standard Audi Q7 from 0 to 100 km/h in 9.3 seconds. If the driver wants to accelerate even faster, the electronics also activate the electric motor to make use of the decisive advantage that the electric motor has: Its torque, unlike the combustion engine, is available as soon as it pulls away.

More fun accelerating

In practice, this torque boost provides a new dimension to acceleration, especially in the lower speed range. Over the first four metres, the Audi Q7 hybrid leaves its opposite number with the V6 petrol engine a full metre behind. In the sprint from nought to 100 km/h, the "boost" from the electric motor gives it a lead of 1.7 seconds.

And when it comes to pulling power, important when overtaking, the additional drive gives impressive assistance. The "boost" is of course automatic and cuts in as soon as the driver depresses the accelerator pedal beyond a certain, slight resistance. The necessary current comes from the battery in the rear.

But the electric motor can do more than just provide extra power. It is also able to feed kinetic energy back into the system and so recharge the battery when the vehicle is braked or coasting. During this operation, known as recuperation, the motor reverses its function in a flash to become an alternator.

Most energy is recuperated when the Audi Q7 hybrid is decelerated from low speed (under 60 km/h) with a rate of deceleration of about 3 m/s2 – a situation that is frequently encountered in city traffic.

The driver notices this no more than he notices another function that also helps to make the new drive system so efficient. If the Audi Q7 hybrid is coasting without the accelerator pedal being depressed, the combustion engine is switched off – this "sailing" is possible at speeds up to 120 km/h.

The six-cylinder engine is also switched off if the vehicle remains stationary for more than three seconds. To continue the journey, all the driver has to do is to remove his foot from the brake and to depress the accelerator pedal again. The engine resumes service immediately. The powerful electric motor will then play the part of the starter motor. This makes it possible to start particularly fast and yet quietly and comfortably.

The intelligent energy management system uses these strategies to achieve a high degree of efficiency in the drive system, making sure that the battery is not overloaded. The hybrid vehicle is able to demonstrate its potential for saving most effectively in city traffic. With an average mileage of 20,000 km per year, the Audi Q7 hybrid recuperates about 720 kWh of energy a year – approximately a sixth of what a four-person household uses.

2008 Audi A8 unveiled!

Audi has officially unveiled the new 2008 Audi A8 series with upgrades across the entire range. The 2008 Audi A8 will carry over the same engine specs although Audi has introduced a new fuel-efficient 2.8 FSI variant.

The 2.8 FSI V6 engine produces 210 horsepower with a maximum torque of 280 newton metres. While having a fuel-consumption of 34mpg, the 2.8 FSI V6 engine allows that Audi A8 to accelerate from 0-62 mph in 8.0 seconds with a top speed of 147 mph.

Exterior changes on the 2008 Audi A8 include include new exterior mirrors, new wheel designs and new-look LED taillights. In Germany the Audi A8 2.8 FSI costs 61,900 euros ($84,363).

The Audi A8 not only offers the sportiest performance of any luxury-class saloon, it also stands out as a model of efficiency. A particularly outstanding example is the new A8 2.8 FSI: superlative performance and excellent comfort make it a joy to drive. But at the same time, with a standard fuel consumption of 8.3 l/100 km, its CO2 emissions of 199 g/km are the lowest in its class.

The new A8 model series features major advancements across the range, which includes the top models Audi A8 W12 and Audi S8, and offers a new driving feel whilst building on traditional strengths. An even more precise driving feel, even better ride and acoustic comfort, and subtle refinements to the exterior and interior serve to strengthen the special status of Audi's flagship model.

Unique character – consistently enhanced
To achieve this, many aspects have been refined in the unique blend of sportiness, elegance, supreme control and sophistication that forms the Audi A8 character. For instance, the more direct steering and re-engineered running gear have produced even more exact handling. Overall travelling comfort has also been enhanced by the modified adaptive air suspension and extensive improvements to noise insulation. These make the Audi A8 one of the world's quietest and most comfortable saloon cars.

The new assistance systems Audi lane assist and Audi side assist promise to make life easier for the driver and considerably enhance safety, especially on long journeys. Their tasks are to alert the driver if the car begins to drift out of its lane and to warn of vehicles in the adjacent lane.

Luxurious, sporty motoring with low fuel consumption
The 2.8 FSI impressively demonstrates how well the Audi A8 combines luxurious, sporty motoring with high efficiency and low fuel consumption. Its efficiency nevertheless comes with exciting performance, as the new high-tech V6 engine produces 154 kW / 210 bhp and delivers its maximum torque of 280 newton metres over the broad rev band of 3,000 to 5,000 rpm. With acceleration of 0 to 100 km/h in just 8.0 seconds and a maximum speed of 238 km/h, the Audi A8 2.8 FSI is an effortlessly powerful performer.

High-tech engine with lightweight design concept
Thanks to its state-of-the-art engine and an exceptionally low vehicle weight of only 1,690 kilograms, the A8 2.8 FSI has a standard fuel consumption of just 8.3 litres per 100 kilometres. That is equivalent to CO2 emissions of 199 grams per kilometre – the lowest value of any luxury-class car. Here the dual benefits of low vehicle weight – thanks to lightweight aluminium design based on Audi Space Frame technology – and low wind resistance make themselves felt, in both excellent performance and equally good fuel economy.

The new six-cylinder engine demonstrates "Vorsprung durch Technik" with FSI petrol direct injection and the innovative Audi valvelift system. This new technology adjusts the valve lift, varying it between two levels. The Audi valvelift system uses sliding cam units mounted on the intake camshaft, which are moved by an electronic control mechanism. Depending on the engine power demand, the valves are opened wide or less wide as determined by the position of the cam units.

The advantage: the required quantity of fresh charge can be very efficiently controlled via the valve opening. Most of the time, the throttle valve remains fully open, thus substantially reducing throttle loss. In combination with a series of additional measures to reduce friction on numerous components, the Audi valvelift system reduces fuel consumption by ten percent.

High power transmission comfort with athletic qualities
The new A8 2.8 FSI is equipped with front wheel drive and the multitronic continuously variable automatic transmission. The multitronic not only offers unmatched power transmission comfort with fully jolt-free acceleration, its tall overall gear ratios make for very fuel-efficient motoring. Nevertheless, the seven fixed ratios available in manual mode reveal its thoroughly athletic qualities.

In Germany the Audi A8 2.8 FSI with its extensive standard equipment costs from 61,900 euros incl. VAT.

Consistently enhanced
The A8 impressively embodies the progressiveness of the Audi brand: its extremely rigid lightweight body based on the Audi Space Frame principle, the powerful FSI and TDI engines, quattro permanent four-wheel drive and the highly acclaimed MMI operating system are a few of the elements that demonstrate Audi's impressive "Vorsprung durch Technik" in the luxury class.

The character of the Audi A8 is formed by a synthesis of dynamic and agile performance and exceptionally refined ride and acoustic comfort. While setting new standards with its agility and steering precision, the A8 displays handling with definite sports car qualities. Even long journeys are both relaxing and pleasurable.

To underscore the unique character of this luxury saloon, Audi has further enhanced the two major strengths of the A8. The rack-and-pinion steering with variable steering ratio and servotronic speed-dependent power assistance has been optimised and engineered for a more direct feel. The dampers, supports and tuning of the adaptive air suspension have been revised. As a result, the A8 shows an even more spontaneous response to steering input, tightly follows winding country roads and effortlessly maintains a smooth straight line at high speeds.

Air suspension with even more sensitive comfort
Gains in performance and handling are matched by those in ride comfort: the standard-specification adaptive air suspension is now even more sensitive in responding to fine bumps. The electronically controlled variable dampers are now fitted with new seals to reduce friction. These are combined with new valves that have optimised characteristic curves, and the entire hydraulics have also been retuned. The A8 absorbs expansion joint grooves with supple ease and without even the hint of a vibration. With the addition of an insulation package to reduce rolling noise and road noise, the luxury saloon from Audi offers outstanding comfort.

Exemplary soundproofing
Even the complete acoustics of the A8 have been optimised with the use of innovative materials – after all, Audi approaches noise insulation as a component of its intelligent lightweight construction. The result: without gaining weight, the Audi A8 achieves the lowest rolling, road and ambient noise levels in its class. Being one of the quietest cars in the world is an important element of the relaxing long-distance comfort that is a hallmark of the Audi A8.

Assistance systems bring comfort and safety
Drivers of the Audi A8 can rely on the support of the most up-to-date assistance systems. They serve to enhance comfort and combat driver fatigue on long journeys, thus making an important contribution to safety. The new Audi side assist in the A8 makes use of intelligent radar technology.

The system is especially designed for lane-changing manoeuvres and warns the driver of dangerous situations: whenever there is another vehicle in the critical zone, a yellow LED display in the exterior mirror housing lights up and remains on.

If the driver of the A8 activates the indicator to change lane even though the warning display is lit up, the LEDs become brighter and flash more quickly at shorter intervals. This signal is almost impossible to miss as the peripheral vision of the human eye is extremely sensitive to changes in contrast.

Audi lane assist warns the driver to prevent an unintentional departure from the lane. A small camera positioned above the interior mirror on the windscreen observes the road ahead of the car and a high-speed computer detects the lane marking lines. If the driver moves towards one of these lines without indicating, Audi lane assist makes the driver aware of this by a vibration in the steering wheel.

Still a step ahead in the luxury class
The clear and progressive design idiom of the Audi A8 stands out for its timeless quality. The exterior design has thus only been accentuated at carefully chosen points – from the modified single-frame grille and new exterior mirrors with integrated turn signals to the new wheel designs and LED tail lights with their innovative night design. To complete the range, the A8 is available in new paint finishes and with sophisticated aluminium trim inserts plus new interior colour schemes and inlays.

The Audi A8 thus resolutely continues its progress on the road to success. With sales of over 100,000 vehicles so far, the current model has already exceeded the total sales volume of its predecessor. And it is continuing to make gains year by year in a market segment that has remained flat overall. How come? Because the A8 steadily attracts customers from other brands with its clear character, while at the same time product loyalty and repurchase rates among A8 drivers are above average.

Audi developing electronic driving coach to boost fuel economy

Few factors affect fuel economy more than individual driving style, and anyone who's gotten behind the wheel of a modern vehicle equipped with an onboard computer has inevitably played the consumption game. Audi is taking the concept of an insta-mile-per-gallon gauge to the next level by developing a system that analyzes driver behavior and then tips off drivers on ways to reduce consumption.

The system was presented at the TechDay 2007 seminar in Germany, where Audi sought to draw focus on drivers, fuel usage and emissions reduction. The automaker contends that just by changing the habits of the driver, fuel economy numbers could be boosted by as much as 30-percent, without having to sacrifice "speed and dynamism."
The system also incorporates the vehicle's sat-nav to make route suggestions based on traffic and road conditions, something that should be available in next generation "digital road maps."

2008 Audi A4 Revealed

Audi today let loose images of the new 2008 Audi A4. First impressions? It really doesn't look all that different to the current A4, but it is.

Audi had set out to create the new A4 with excellent driving dynamics and sporty proportions in mind, in order to that the German manufacturer has had to do some serious changes.
Longer by roughly 113 mm (4.7 meters overall length), the new A4 has had some surgery to shorten the front body overhang while the bonnet and wheelbase are both longer than before. The differential has swapped places with the clutch (torque converter in the auto) to allow the front axle to move forward by 154 mm. Audi says this will ensure ideal axle-load distribution.

Audi has also tinkered with the suspension, the new A4 is blessed with a completely new suspension design, one which is mostly made from weight-saving aluminium.
One of the noteworthy technologies in the new A4 is the Audi drive select, a system which can vary the engine, auto transmission, steering and suspension damping characteristics to suit the driver's need, on the fly.

Enough about the cars design and technology, what about the power? Audi will give buyers a choice of five different engines, from 105 kW to 195 kW (not including the new RS4 obviously).
The four-cylinder petrol engines will all be turbocharged, like the diesels, and mated to either a six-speed manual gearbox, tiptronic automatic transmission or multitronic continuously variable transmission (CVT). The A4 will be driven via either front-wheel drive or Audi's famous quattro permanent all-wheel drive.
The new A4 will be on display at the Frankfurt Motorshow next month and also make its way to the Australian Iinternational motorshow (Sydney) in October.
"The all new A4 will be a great addition to our range. It offers a superb combination of stylish design, sophisticated technology, precise balance and handling and of course it will offer an excellent alternative for luxury car buyers when it arrives here next year," Audi Australia managing director Mr Hofmann said.
The 2008 A4 is expected to land in Audi dealerships around April next year. Pricing and Australian specifications are still not finalised.
