My name is John & I am Ford Motor Companies Fuel Economy Technical Expert. After working for over 20 years improving conventional production car/truck FE I wanted to try something with fewer constraints.

As you can see in the ebay photos it is a tandem seated reverse trike. This design offers the lowest frontal area and Cd.

The vehicle and powertrain have been optimized with computer based simulation. GPS based coast down tests were used to confirm the Cd.

The best FE of 125mpg was achieved using narrow motorcycle wheels and a small rear sprocket. I have had it up to 106mph and it was still accelerating.

It is offered for sale because I am nearly finished building another one like it except it is a plug in hybrid. The garage is full something has to go.
