Brabus Smart ForFour
A Brabus-prepared sports version has been available since 2005. It is powered by a turbocharged Mitsubishi 4G15 engine, developing 130 kW (177 PS; 174 hp), 27 PS (20 kW; 27 hp) more than the Mitsubishi Colt CZT.
The Brabus Forfour requires higher than standard octane fuel to develop full power. It can reach a maximum speed of 221 km/h (137 mph) and accelerate from zero to 100 km/h (62 mph) in 6.9 seconds. The Forfour was to be sold in the United States along with the revived Smart Formore vehicle. However, due to slow sales, the Forfour has been phased out from production
