Audi Spain released an official video of the mighty new S8 cruising in Barcelona. The car is technically brilliant. Superb quality, great ride, and a new 4.0 liter V8 delivering 382 kW (520 hp) and 650 Nm (479.42 lb-ft) of torque which takes it from 0 to 100 km/h in 4.2 seconds. But even in the video you can see it is a bit too cold, too emotionless! Compared to this, Mercedes S63 seems like a lot more fun.
