Audi is testing the new S4 in Nurburgring. The car features an aggressive body kit with larger air intakes, lower sports suspension, new wheels and quad exhaust tailpipes.
The model will be equipped with a 3 liter V6 TFSI engine producing close to 350 hp, while it is expected to make the 0-100 km/h in about 5 seconds. It will probably be presented at the Frankfurt auto show in September.
