The Audi S4 is a sporty car produced with sedan, station wagon and convertible bodies on the updated A4 version. These versions of the S4 have the same engine as the previous version. This power unit is an all-aluminum 4.2 L, 40-valve V8 with two DOHC heads borrowed from the Audi A8 model. It has 253 kW (344 hp) / 7000 rpm, 410 Nm / 3500 rpm of torque and is more powerful than the RS2 and almost as powerful as the B5 RS4 model. The maximum speed is electronically limited to 250 km / h. Official data: The sedan reaches the speed of 0-100 km / h in 5.6 seconds (station wagon in 5.8 s, convertible in 5.9 s). The main changes are the new suspension springs and shock absorbers, as well as the new Torsen t-3 central differential, which delivers torque asymmetrically in a ratio of 40:60 and has the ability to deliver all 100% to the rear wheels if required.
