The Rocky Mountain Institute has formed a plug-in electric vehicle (PHEV) consortium who will work with a group of companies, Google among them, to design what is in their opinion an ideal PHEV for the U.S.
This team is actually headed by John Waters who had once helped to design the EV-1 battery pack and has once worked with lithium-ion battery company EnerDel.
Mr. Waters has publicly declared that the Volts’ design and engineering are flawed and doomed to failure:
“[The Volt] is a 4,000-pound vehicle. The drag coefficient is around .30. They [GM] forgot everything they learned on the EV1 so for me, it is a very discouraging concept, the fact that it is inefficient.
Therefore if it is inefficient, it takes more batteries on board…and batteries cost money, and you’re not going to pay for them. So this is a concept that is not going to work.
So until they start hearing the RMI message, really, of lighten your vehicle, make it more efficient, and that the energy you put on board is a minimum…then you can afford it. The cost equation does work.”
It is a great thing that there are so many opinions out there, we must be on the verge of a revolution.
In terms of the curb weight for the prototype:
EV-1: 3084 lbs Chevy Volt: 3140 lbs
Sour grapes Mr. Waters?
Thanks to Alex for the tip.
