It might not have the right M gearbox, the right M limited slip differential or the shortest name, but the fact of the matter of the matter is, the M135i is one of the coolest cars to get for about €40,000 (in Germany).
German tuner Versus Performance have found the 3-liter TwinPower had much more to give and have boosted it from 320 PS to 390 PS by playing with the software (€1,899). Additionally, as much as 418 PS if you also take into account a custom sports exhaust that adds another €4,599 to the price.
Also added to the M135i is a set of custom shocks and springs: €1,799 for the kW Variant 3 or €2,499 euros for the KW Clubsport Coilovers 2-Way.
