Apart from the more powerful engine and dual-clutch gearbox, the S5 Evo was equipped with the same specifications as the standard S5. This meant that it used the same quattro permanent four-wheel drive system with variable torque distribution from its basic setting of 40% to the front and 60% to the rear axle. The Evo also featured a button for ‘comfort’ and ‘sports’ mode, the latter providing quicker gearshifts, better throttle response and a firmer ride.
The exterior of the car was also identical to the regular S5 and Audi officials on the day weren’t willing to confirm if the Evo-spec car would eventually enter production as a special edition model, according to the guys at InfoMotori who got to test drive it. If the Evo were to be built, it could serve as a stepping stone between the standard 354hp (260kW) S5 and the upcoming RS5, which is expected to feature a 450hp (335kW) version of the 4.2L V8 engine.
