TdS Report #32: Team Profile: Hybrid Challenger II

We last saw this vehicle at the Tour de Sol in 1996, but it had many
difficulties. "I don't even want to talk about it," said Clarence Ellers. "We
found a lot of bugs and worked them out."

This conversion of a Chevy Lumina is a parallel hybrid. The rear wheels are
driven by a 1987 Volkswagen Vanegan engine and transaxle and the front is
driven by a brushed DC motor. "There is a knob under the dash that sets the
change-over speed. You run on electric at all speeds under that. When you get
up to highway speeds it switches automatically over to gasoline."

"There are 26 Optima Yellow-top batteries, wired as 13 pairs in series. That
gives a 196 Volt system." A set of flexible solar panels are glued to the roof
and are used to keep the 2 12-Volt batteries charged.

"I bought the car in 1990. About 1992 I converted it in about 6 months. I've
been driving it for 12 years. It has accumulated about 4000 miles since it is
mostly a prototype."

The car and the patent it is based on are for sale. "I would like to sell the
patent rights for $100,000, non-exclusive. I'll consider any offer for the van
