These small commuter cars had a single seat and were powered by a 12 or 16 horsepower gasoline engine[2] or a 4 hp electric motor.[3] A diesel engine was offered,[2][3] but none were ordered with it.[2]

The 12 HP version was guaranteed to get 100 mpg‑US (2.4 L/100 km; 120 mpg‑imp)[2][3] when driven at a steady 40 mph (64 km/h).[2] The 12 HP version averaged 80 mpg‑US (2.9 L/100 km; 96 mpg‑imp), and the larger 16 hp averaged 60 mpg‑US (3.9 L/100 km; 72 mpg‑imp) to 70 mpg‑US (3.4 L/100 km; 84 mpg‑imp). The standard fuel tank had a capacity of 3 US gallons (11 L)[3][6] while a 10 US gallons (38 L) tank was optional.[3]

The engine was mounted behind the driver and was coupled to a snowmobile-style CVT belt drive transmission. Final drive to the rear wheel was by chain. The gasoline-powered Free-Way did not have a reverse gear in its transmission.[2][3] An electrically powered reverse drive was offered as an option,[2][3] but was never made available.[2]

Front view

The Free-Way had a welded tubular steel frame, with a secondary perimeter frame at bumper height to protect the driver from impacts. Suspension was fully independent, with two wheels in front and a single wheel in the rear. The fully enclosed two-piece fiberglass body was approximately 0.125 inches (3.2 mm) thick and had the color molded into the material and was available in high-visibility red, yellow, or orange.[3] The lower body included a full undertray to reduce the drag coefficient of the vehicle.[3][6]

The Free-Way had a single headlight and per federal standards were intended to be licensed as a motorcycle, but in some states they were titled as cars.[7]

About 700 Free-Ways were sold before the company closed in June 1982.[8]
