The S2 was initially easy with a 2.2 L turbocharged locomotive which produced 220 hp (162kW) with late models producing 230 hp (169kw. It will make 0-100 kilometer/h in 5.8 seconds, keeping to a high velocity of 246 kilometer/h (154 mph. The S2 avant reaches 100km/h in 6.1 seconds and has a best velocity of 242 kilometer/hour.

The 3B locomotive fitted to the other S2 models (MY91 & 92 but) is pretty often very to the 20V turbocharged RR engined which was fitted to the high propagation of the UR Quattro which ceased product in 1991. Both work the like trusty 2226cc stop, a KKK24 turbo and same Motronic locomotive administration systems.

The job of shoe-horning this locomotive into the serial 4 Coupe was gated to Schmidt Motor sport by Audi in 1990. The single differences to the RR facility (AFAIK) are in the position of some auxiliary components. One better change, non now linked to locomotive, is that the RR diligence uses the super-strength '016' infection whilst the 3B in the S2 Coupe used the one '01A' infection as was fitted to the usually aspirated 20V Coupe Quattro.

The torque feature of the 3B locomotive is mill tuned by the ECU to be only inside the good controlling margins of the 01A gearbox. As such, the 01A infection is the weakest contact in the string for anyone considering important might & torque hikes on their loved 3B engined S2.

Fortunately the 016 infection can be bolted onto the 3B locomotive with no better trouble. The right hold clash home is taken to control a couple with the stimulation tool on the 016 tranny.
