CLEVER stands for Compact Low Emission VEhicle for URban Transport and is the result of three years of research and design. This vehicle combines the safety of a microcar, and the useful maneuverability of a motorbike, all while powered by a natural gas fueled engine.
This vehicle that looks a lot like the Brinks Dynamics Carver is powered by a 230cc BMW engine modified by the Institute Français du Pétrole to accept the natural gas. This engine produces 17 hp and a maximum torque of 15.5 Nm at 6,300 rpm giving the CARVER a top speed of 62 mph. The gas bottle fuel tanks provide a range of approximately 93 miles.
This three-wheel vehicle leans, just as a motorcycle during cornering (exactly like the Carver) using two hydraulic actuators to rotate the cabin around a maximum of 45° each way. The system is controlled by a computer which calculates the desired lean angle by taking into account speed, tilt angle of the cabin, and lateral acceleration.
