The GM EV1 weighed 2920 pounds and reported 164 Wh/mile used. It achieved this incredible efficiency with a very smart design. It had a ground breaking 0.19 coefficient of drag. The Toyota Prius is 0.25 and the Tesla Roadster is 0.35
The NiMh pack was 26kWh and weighed 1170 pounds, and achieved a 160 mile range.
The Chevy Volt lithium ion battery pack is 400 pounds and holds 16 kWh and can only be smaller than the NiMh EV1 pack.
Drop the Chevy Volt battery pack into an EV1 and you lighten it up by 770 pounds, now you have a 2150 pound car.
The Tesla Roadster has a worse coefficient of drag and aerodynamic loss doesnt exceed rolling resistance til about 40 mph, considering the .19 coefficient of drag for the EV1 I would expect that the EV1 to do at least as well. Lightening the car up by 26% should decrease the Wh/mile by around 13% if not more, getting it down to about 143 Wh/mile.
Now you have a Lithium Ion battery EV1 with a 112 mile range.
GM complained that the EV1 was too expensive to make.
The Volt has to have a similar AC motor, controller and management system to the EV1.
By deleting the gas motor, generator, fuel system, exhaust system, you should save around $5000 from the cost of a Volt. ( You also save the new owner tons of maintenance costs… )
So if GM can sell the Volt for $30,000 ( with tax credit ), the new EV1 should be about $25000.
$25000 for an electric car with 112 mile range would be instantly competitive in todays market.
I would love to see someone get their hands on an EV1 shell ( 40 of these exist in the hands of universities and museums, GM crippled them and gave them out after they criminally destroyed the rest ) and a Volt and gut the Volt for its battery and build a new EV1 just to prove a point.
