Modification
Smart cars have been modified by Brabus of Germany, resulting in Brabus production models. Other companies modify the Smart to use motorcycle engines, such as the Suzuki Hayabusa 1340 cc inline four-cylinder. These cars are known as Smartuki. The most powerful models can accelerate from 0 to 60 mph (0 to 100 km/h) in less than 3.5 seconds. The original car was fitted with a mildly tuned engine and ran 0-60 mph in 4.5 seconds, 1/4 mile standing start in 12.4 seconds and a top speed of 132 mph (212 km/h). It is possible to push the GSXR engine further; nitrous Oxide will add another 50 bhp (37 kW; 51 PS) - 80 bhp (60 kW; 81 PS) and there is a turbocharged option.
Some companies and individuals upgrade the original engine to Brabus spec, but these have been taken even further by some with many aftermarket upgrade options available.
