The relatively light weight of the fuel cells led to his idea of a stable, narrow vehicle with a low center of gravity.

While waiting for fuel cell technology to catch up,[3] he eventually settled on a design for the car to have individual electric motors for each wheel.

[needs update] Actor George Clooney took delivery of the first Tango kit on August 9, 2005, which was a major milestone for the company.

The second car eventually found its way into the second-floor office of Google CEO Eric Schmidt as part of an April Fools' Day joke.

After passing many of the performance tests with ease, the car failed to complete the 100 mile durability run (one of the complicated set of requirements for the prize) and was eliminated from the competition.

One prototype vehicle has been produced by the company and was shipped to Prodrive in the United Kingdom in January 2005, where the design was refined for production models.

Commuter Cars states that the Tango's heavy battery pack and low ground-clearance combine to give it a center-of-mass 11 in (280 mm) from the ground, allowing for stable handling.

About two-thirds of the 3,000 lb (1,400 kg) curb weight in the prototype is taken up by the batteries, twin motors, and controller, mounted low in the frame.
