Nice. I like that method better, where the engine only provides electricity and all drive is from electric motors.

I love the race mode on the Porsche, which sounds like it acts similar to the F1 KERS system from last year.

But I agree: I love the idea of a gas engine powering the batteries only. And I love the Evora :heyes: :heyes:

I'll take one of each, please.

YUMMY!

Note I didn't read the article.

The down side of this method is your energy conversion losses. Chemical to Mechanical to Electrical driving the motor, or worse yet (by at least 10%) Chemical to Mechanical to Electrical to ElectroChemical (battery) to back to Electrical. In a parallel drive method you can cut out at least some of the Mechanical to Electrical conversion.

But then on the otherside the engine can be tuned to be super efficent in a very narrow output range, since it doesn't have to move a car from 1% to 100% effort from 1mph to 100mph. So the above losses might be offset by this gain. If I remeber right a helcopter company got 400+ STEADY STATE HP (not peak) out of an STi engine doing this.

Although when your talking steady state efficency, there's more effective fuels and inductions to do it with.

that same 'helicopter company' also ditched the sti motors and went to one of those more efficent engines (aka a turbine).

also a nice proper looking hybrid.

Sweet. User Power stationary mode is an interesting concept, especially for boy scouts and the paranoid.
