Abstract
The lightweight electric vehicle comprising two front wheels and a rear wheel comprises a high-strength load-bearing chassis comprising a base, sides and bulkheads as a safety cell for the driver. A separate lightweight plastics body forms an aerodynamic tear drop-shaped outer skin. Both the body width of about 1 m and the chassis width of about 60 cm are very narrow. This gives high travel performance, minimal weight, air resistance and energy consumption. In addition, increased overall safety, good road holding and a high degree of manoeuvrability are obtained.
Claims24
A lightweight electric vehicle comprising
- a load-bearing narrow shell-shaped chassis of high-strength rigid construction forming a safety cell for surrounding a driver, said chassis having a pair of coextensive side walls, at least one front transverse connection connected to and between said side walls and one rear transverse connection connected to and between said side walls, each said side wall extending upwardly to maintain the body of a driver between said side walls;
- a pair of front wheels connected to and situated outside said chassis;
- at least one rear wheel connected to said chassis;
- and
- a separate light-weight plastics body of an aerodynamic slender tear-drop outer shape covering all said wheels and said chassis.

A lightweight electric vehicle comprising
- a narrow load-bearing shell-shaped chassis of high-strength rigid construction for receiving a driver, said chassis having a front bulkhead at a forward end, a rear bulkhead at a rear end for supporting a driver, and a pair of side walls extending between said bulkheads, each said side wall extending upwardly to maintain the body of a driver between said side walls;
- a pair of front wheels mounted on said chassis near said front bulkhead and located laterally outside said chassis;
- at least one rear wheel mounted on said chassis near said rear transverse connection;
- and
- a lightweight body having an aerodynamic slender tear-drop shape covering at least said front wheels and said rear wheel.
