AUDI E-TRON : A high-performance sports car with a purely electric drive system

Audi presents the highlight of the IAA 2009: the e-tron, a high-performance sports car with a purely electric drive system. Four motors – two each at the front and rear axles – drive the wheels, making the concept car a true quattro. Producing 230 kW (313 hp) and 4,500 Nm (3,319.03 lb-ft) of torque, the two-seater accelerates from 0 to 100 km/h (0 – 62.14 mph) in 4.8 seconds, and from 60 to 120 km/h (37.28 – 74.56 mph) in 4.1 seconds. The lithium-ion battery provides a truly useable energy content of 42.4 kilowatt hours to enable a range of approximately 248 kilometers.

The most important development related to batteries for electric drives are lithium-ion cells. Numerous experts throughout the world are working on their further development for use in cars, with the primary objectives being to reduce weight and increase capacity and performance. Audi has also opted for this technology, both for use in a hybrid production vehicle, such as the upcoming Q5 hybrid, and in the e-tron test platform.

The requirement specification for the concept vehicle goes far beyond battery technology and the replacement of the combustion engine with an electric drive system, however. The Audi development engineers decided back in the concept phase to design practically every component and technology based on the new requirements of electric mobility. The interaction of all elements has a decisive influence on the factors efficiency, range and practicality.

2010 AUDI A5/S5 CABRIOLET

The 2010 AUDI A5/S5 CABRIOLET softtop results in a genuine Cabriolet facade, making the AS/ S5 Cabs instantly recognizeable as convertibles, not coupe wannabes when the rain clouds open up. Plus, the softtop boasts Audi's Acoustic Roof technology, which features 0.6-inch-thick sound-deadening foam that creates a serene, coupelike ambiance.

Moreover, the cloth top that opens in 15 seconds and closes in 17 (BMW's power hardtop on the 3 Series needs 22 to open and 23 to close) allowed Audi to reduce weight and optimize cargo capacity, which, at 113 cubic feet with the top down, is 3.9 more than that of the 3 Series.The 50/50-split back seat folds forward, swelling capacity to 26.5 cubic feet. For cold-weather, open-roof motoring, the

Cabs offer a neck-warming, head-level heating system that uses a three-level-adjustable fan to send hot air through a vent on the top side of the seatback. Even niftier, the Audi's softtop can be operated at speeds of up to 31 mph.

Of the four variants coming stateside, the 211-horse 2.0T quattro strikes us as the consummate all-around option, its all-wheel drive remedying the base front-drive 2.0T's compromised traction in the wet and moderate torque steer under aggressive throttle. Further, the quattro's six-speed auto is more rewarding than the front-drive's CVT. Itching for a V-6? There's the 265-horse 3.2 quattro, which feels plenty quick but not as lively as its torquier 2.0-liter counterpart. For the ultimate thrill ride, the S5 Cab is the ragtop of choice, its seven-speed dual-clutch auto and 333-horse supercharged V-6 delivering the mightiest punch, its quattro and torque-vectoring Sports Rear Differential providing the most tantalizing experience.

Audi TTS roadster

The quickest TT ever is still trying to catch up to the Porsche Boxster.

Audi is ascendant lately, witha string of endurance Tacing wins,
worldwide sales up four percent in 2008 to crest one million for the
first time, and the R8 powering the brand into the supercar arena. So
perhaps it's not so surprising that the company has the confidence to price its new TTS roadster, the hottest version of the TT, within spitting distanceof the Porsche Boxster ($775 more, actually).

Not that it's quite an apples-to-apples comparison. The TTS comes with
more standard equipment, most notably all-wheel drive and a dual-clutch
automatic transmission, if you want a similar whiz-bang gearbox in a
Boxster, you have to shell out a whopping 63420. On topof that, the TTS's
heavily tweaked direct-injected. 2,0-liter turbocharged in-line four puts out 10 hp more than the base Boxster anda significant 44 lb-ft more torque. Audi engineers modified the block and the cyhnderheadas well as the connecting rods, pistons, lutbocharger, and injection.system to make sure the boostedengine wouldn't self-destruct.

The result is a claimed o-to-60-inphtimeaf 5.1 seconds, nearly
matching the more powerful {and $9325 more expensive) Boxstcr S. The
TTS is also quite frugal, considering its performance. Its ETA combined
fuel economy rating of 24 mpg is the same as those of the Suzuki SX4
Sport and the base Mitsubishi Lancer, two cars that would be specks in
the Audi's rearviewmtrror in a drag race.

The TTS drives Uke a very fast, very grippy, and very expensive Volkswagen GTI. We love the GTI.but we want a $50K roadster to have a bit more brilliance in the steering and a bit better chassis balance,
Audi did what it could; it lowered the suspension, fitted
adjustable magnetic dampers, and quickened the reaction of
the Quattro system, but this is still no mid-engine sports car.
