The focus for the industry is undoubtedly on improving efficiency, but in some projects engineers can spend less time thinking about fuel economy and more time improving speed and acceleration.

Hot hatches like this are defined by performance, how fast they can reach 100km/h from a standing start, how much lateral g you can generate on challenging road layouts and, when you're driving through populated areas, aural pleasure. The RS3 uses the same 2.5-litre turbocharged five-cylinder gasoline engine as the one that powers Audi's TT RS coupe.
