The 2008 Audi S5
Why It's Special:
Walter de’ Silva, Head of Volkswagen Group Design, says “The Audi A5 is the most beautiful car I have ever designed”; not to argue with an auto industry giant, but we think he really meant the Audi A5’s sexier, faster counterpart – the Audi S5. Not to imply that the A5 isn’t a stunner, but when you throw in the S5’s aggressive bumpers, larger wheels, dual exhaust, brushed aluminum mirrors and larger rear spoiler you end up bordering on automotive design perfection.
Under the Hood:
While it’s easy to get caught up in the gorgeous lines of the S5’s body, there is plenty to appreciate beneath its metallic skin. Under the hood lies Audi’s world-class 4.2-liter FSI (Fuel Stratified Injection) DOHC V8, the same engine used in the RS4 saloon and the new R8 supercar. Nestled in the S5, the V8 has been modified from its performance origins to better suit the car’s GT characteristics. Most notably the S5 has a two-stage magnesium intake manifold which is able to optimize runner length and thus, combustion efficiency across the entire rev-range. The results are 354hp @ 7,000rpm and an insanely flat torque curve. 85% of the engines peak torque is available from 2,000rpm, and the maximum 325 lb-ft are available at a lowly 3,500rpm, mind boggling numbers for a naturally-aspirated V8.
Gear changes are handled by a 6-speed manual transmission, topped-off with a precise short-throw shifter. Dynamic handling is provided by an advanced independent suspension, utilizing an aluminum 5-link design up front and a trapezoidal-link rear suspension. The S sports suspension also features firmly tuned springs and dampers to give the driver precise feedback and control. As with all Audis, the S5 is equipped with the amazing Quattro all-wheel drive system. Engine torque distribution defaults to 40/60% front to rear and is continuously variable, constantly adjusting to varying road and traction conditions.
The Verdict:
The effective combination of FSI power and Quattro all-wheel drive results in a car capable of 0-60mph in 5.1 seconds and quarter mile times in the low 13-second range. Perhaps what’s most amazing about the S5 is that the car delivers all this performance without sacrificing practicality. Inside you will find four real seats that actual people can fit in, along with a huge trunk out back. Really the perfect car for that 9am tee-off and post-lunch autocross event.
