A European consortium is wrapping up a three-year to develop a three-wheeled, natural-gas micro-car: CLEVER ( C ompact L ow E VE hicle for U R ban Transport).

CLEVER, a million (US$3.9 million) is an enclosed two-seater that the safety of a microcar, and the maneuverability of a while being less than other vehicles as it on compressed natural gas.

Its strengthened frame will the driver in a crash and the vehicle have a top speed of approximately 50

The 230cc BMW engine—modified by Institut du Pétrole (IFP) to use natural 12.5 kW (17 hp) of power and maximum of 15.5 Nm at 6,300 rpm.

IFP the swept volume of the engine allowing the engine to run more and bringing several benefits. The engine speed both emissions and lowers engine which enhances fuel It also produces less The increased displacement contributes to the torque, providing the level of needed in urban traffic.

Fuel consumption is estimated to be 2.4 km gasoline equivalent (98 mpg US), 59.5 g/km of CO 2 emissions.

The tank system.

The compressed natural gas is stored in two cylinders that are custom for ease of handling and refilling. The two gas bottles provide a range of 150 km (93 miles).

A problem with vehicles with a symmetrical layout is the tipping moment cornering, which cannot be at high speeds if the vehicle has a wheelbase.

To solve this the vehicle’s center of gravity can be towards the center of the corner, for by angling the complete vehicle—just as a does when it corners.

This is the approach used by three-wheelers”—and there have two basic technical methods to it:

Change the camber of the two parallel (front or rear) with or tilting the vehicle.

Angle the around a pivot relative to the of the two parallel wheels.

Vehicles use the first concept have around since the forties Neumann-Neander 1948) and the method has been used for concept (Mercedes Benz F300 Jet” 1997).

Vehicles that use the second include, for example, the “GM Lean dating from 1983, the from Vandenbrink and various vehicles from Honda, the Honda Gyro/Honda Stream from 1984. There has a BMW concept on this basis in the BMW in Munich since 1991.
