The Smart Fortwo is a rear-engined two-seater city car.
The Smart features an automated manual transmission without a clutch pedal, 6-speed for the first generation, 5-speed for the second. Input from floor-mounted shifter or optional steering wheel-mounted paddles controls a servo-operated clutch and sequential automated gearbox. The vehicle may be driven in automatic mode, though the shift points are not as smooth as in a traditional automatic transmission. In paddle shifter mode, the operator controls the shift points but cannot feather or adjust the speed of the clutch. Thus some skill, and a slight lifting of the accelerator pedal, is required to achieve a smooth shift.
The Smart features interchangeable body panels—whereby one car can easily assume a different look. To accommodate a licensing agent's notation of a vehicle's color, the fortwo is sometimes registered as silver or black based on the Tridion frame color, which remains constant regardless of the body panels.
The engine ranges featured turbocharged three cylinder motors. Originally, the base petrol engine had 599 cc, but displacement increased to 698 cc with an early restyling. It was available in 37 kW (50 hp) or 45 kW (61 hp) variants. The turbodiesel engine has 799 cc displacement with 30 kW (40 hp). Engines are mounted in the rear of the vehicle.
