When this Smart Fortwo rolled out of the factory it was powered by a turbo 698 cc inline-three that made around 60 horsepower. However someone replaced the factory engine with a 1441 cc inline-four from a Kawasaki ZZR1400 (Ninja ZX-14) motorcycle. The new engine produces 200 horsepower for 333% more power.
