Not quite; he kept the Geo transaxle, but "gutted" it so all it had was 2nd gear. It then ran lighter weight oil (not the usual 90w gear lube).

That's what James Worden was all about.  He obsessively tuned efficiency in
his EVs.  That's why he routinely won the Tour de Sol, and also part of why
his cars were too expensive to ever sell well.

That's him! Efficiency was his goal; and he was good at it achieving it.

The cars were expensive simply because they were hand-made in such low quantities. The efficiency enhancements added little to their cost, but helped them sell better. So they were probably a step in the right direction.

I think Worden saw the GM EV1 as his real competition. It was another exceptional EV that was designed from the ground up for efficiency. Neither car was the "same old thing" -- an EV conversion of a standard ICE vehicle, with an old forklift motor and off-the-shelf batteries. Instead, they showed us what an EV can really do if designed right from the very beginning.

I think the genius of Bob Rice was to realize that a) scratch-built EVs really *can* be built cheaper and simpler than ICEs, and b) Worden's improvements could be applied to *any* EV that was built from scratch.
