The original E92 M3 boasts 420hp from its powerful naturally aspirated 4.0 liter V8 engine. The GTS version is boosted to 450 hp, which makes 112.5hp per liter displacement. The power-to-weight ratio is also improved, by lowering the gross weight of M3, now the figure is 3.4 kg per hp. Almost perfect for a racing car, but lets not forget that M3 GTS is street legal.
Furthermore, the 7-speed M Dual Clutch Gearbox is re-tuned for maximum performance. The suspension is also revised. With these upgrades – GTS accelerates from 0 to 100 km/h in 4.4 seconds and the top speed is 305 km/h.
