Audi's diesel-powered R10

Remember Audi's diesel-powered R10 TDI sports-prototype, which won the Le Mans 24 Hours last month? Well, the brits decided to put it against a Harrier GR7 "Jump Jet" multi-role combat aircraft in a race at RAF Wittering in England yesterday (6 July). If you think the Harrier gave it a beating, guess again….

Although the R10 didn’t actually win in the standing one-kilometre race, it gave the Harrier a scare as the Jet won just by one-tenth of a second !

The Audi, the first diesel-engined sportscar to win the famous Le Mans race, was quicker off the line - despite the R10 TDI being designed to start races from a "rolling" as opposed a "standing" start and faster to 150mph than the aircraft.

But the Harrier, piloted by Flight Lieutenant Pete Keenlyside, ultimately just beat the Audi to the 1km by literally a "nose" before the jet took off in a spectacular vertical climb.

Audi R10 driver, Allan Mcnish, comments: "I had a practice run against the Harrier moments before the race ‘proper’ and I came very close to beating it - it was a very close run contest. It was essentially a ‘fun’ race but when a racing driver and a pilot get together it quickly becomes serious. For our diesel-powered Audi, which we didn’t modify or prepare specifically for this event in any way, to come so close to beating a Harrier jet-fighter I believe was a tremendous achievement once again for TDI power."

2009 Audi S4 powers

we can say that Audi has improved its fuel efficiency by almost 26 percent. The 2009 Audi S4 Sedan

engine-driven belt of 2009 Audi S4 powers the mechanical charger, providing full thrust right from idling speed. The 3.0 TFSI delivers its maximum torque at 2,500 rpm and maintains this constantly until 4,850 rpm. As you move to the fourth gear, the car goes from 50 to 75 mph in just 4.4 sec. Customers will also be provided with an option of choosing between a regular six-speed manual gearbox and a seven-speed “S-Tronic” dual-clutch transmission.

Talking about the DSG, it can be operated in a manual mode, via paddles, as well as in an automated mode. The wide gear ratio spread of 8.0:1 will allow the seven-speed gearbox to take advantage of the increased power and torque of the 3.0 TFSI. The S-Tronic transmission will come equipped with Audi’s Drive Select feature, using which the driver will be able to 2009 Audi S4

select between “comfort,” “auto” and “dynamic” modes. These three modes affect shift speed, throttle response, and the speed-sensitive steering.

Apart from the three modes, “comfort,” “auto” and “dynamic”, there is a fourth mode as well, using which driver can program according to his or her own preferences. However, the latter will be available only if the car is equipped with the optional MMI operating system. 2009 Audi S4 will also have a new rear differential, which will be controlled by an array of sensors and a high-speed computer. Other features of the car include a sport new interior, xenon headlights, a more aggressive body kit, and 18-inch wheels. There will also be an option of going for Adaptive cruise control and Bang & Olufsen audio.

Audi S4

Audi justifies its smooth drive to fame yet again, with the superior performance oriented 2009 Audi S4. Style, technology and performance have always been hallmarks in all Audi models, but this time it’s even better. Exterior refreshment is seen in the 2009 Audi S4, as well as an engine redesign. The 2009 model has a V8 engine that improves the performance in most aspects. There are two trims available for 2009: the Cabriolet and Cabriolet with Tiptronic. The S4 sports convertible is like an altered version of the A4. With aggressive looks, comfort, convenience and super ride quality, the sports car looks good and feels great.
