## Abstract

The general layout for a front wheel drive, three-wheeled vehicle with two steerable driven wheels in the front of the vehicle, and the motor or motors located in the mid-section of the vehicle. The vehicle is designed for compact motors, in-hub motors, and direct connect motors which allow a significant portion of the vehicle's weight to be moved forward, while integrating location of the passenger seating, steering, and driven wheels allows for a highly stable vehicle. The layout maintains the traditional bucket or bench style seats as found in today's automobiles, and yet allows for weighting and cockpit adaptability for different market demographics.

## Claims

### Claim 1

A three wheel vehicle comprising:
two driven front wheels which allow primary directional control of the vehicle;
a single non-driven rear wheel;
a passenger compartment, the compartment comprising one or more traditional passenger seats;
a mid-section, comprising the area of the passenger compartment forward of the front of the seat;
a motor or motors to propel the vehicle either directly or indirectly through the front wheels, located in a position which transversely overlaps the mid-section.
