Audi has taken one of its most powerful engines and squashed it into the front of its smallest car, the A1. The engine in question is the 2,5-litre five cylinder unit already doing service in the TT RS, and due in the upcoming RS3. The engineers have put their heads together to get a full 370 kW and 660 N.m from this turbocharged unit. These are figures we would normally associate with the V10-engined version of Audi’s R8 supercar!
