Audi has launched at the 2015 Frankfurt Motor Show the new generation S4. On the outside, the German sports model comes with a more aggressive design. We see a new radiator grille, modified bumpers and bigger wheels.
Under the hood of the 2015 Audi S4 is a V6 3.0 TFSI engine that can deliver 354 horsepower and 500 Nm peak of torque. Thanks to an automatic transmission, the car can run from stand still to 100 km/h in just 4.7 seconds, while the top speed is electronically limited to 250 km/h.
As for the fuel consumption, the German model will take you just 7.4 liters / 100 km (31.8 mpg US) and will emit just 170 grams of CO2 per kilometer.
As you would expect, the new Audi S4 has a quattro all-wheel drive system and a self-locking central differential that in normal mode will drive the power in a 60% to the rear wheels.
