Claim 6

The vehicle of claim 4 further comprising dynamic braking means, the brake means including by-pass valve for bypassing the pumps and recirculating hyraulic fluid through the motors, and means operated by a brake pedal for varying the flow resistance of the by-passed fluid to vary the load on the motors.

Claim 7

A lightweight automobile comprising: a monocoque body having an aerodynamic shape forming a smooth continuous top and bottom surfaces, four wheels, means independently suspensing the wheels from the body including spring means between the wheels and the body for transferring the weight of the body to the wheels, four drive assemblies connected respectively to the four wheels and positioned inside the shell of the monocoque body, and means supporting the weight of each drive assembly directly from the body, whereby the weight of the assemblies is transferred to the wheels through the spring means, the drive assemblies including drive shafts to the associated wheels for rotation of each wheel, each drive assembly including a motor and a gear drive transmission means coupling the motor to the associated wheel.

Claim 8

A lightweight automobile comprising: a monocoque body having an aerodynamic shape forming a smooth continuous top and bottom surfaces, four wheels, means independently suspensing the wheels from the body including spring means between the wheels and the body for transferring the weight of the body to the wheels, four drive assemblies connected respectively to the four wheels and positioned inside the shell of the monocoque body, and means supporting the weight of each drive assembly directly from the body, whereby the weight of the assemblies is transferred to the wheels through the spring means, the drive assemblies including drive shafts to the associated wheels for rotation of each wheel, each drive assembly including a motor and a gear drive transmission means coupling the motor to the associated wheel.

Claim 9

Apparatus of claim 6 further including means associated with each wheel suspension means for adjusting the level of the body relative to the ground at each wheel.

Claim 10

Apparatus of claim 6 further including an engine mounted within the body, and a ejector pump driven by exhaust from the engine, the ejector pump pumping air into the body shell to cool the engine.
