Well I suppose the usanians might get excited about it but on this
side of the pond we've had the C5 for years :-)
- Equiv to 135mpg
- 130mph
- 250 miles range (will be better when more improved batteries are out in
a few years)
- 0-60 in 3 secs or so.

Not all at once though.

If equiv to 135mpg and range 250 miles that suggests about $4 to recharge
the battery. Assuming 15cents/kWh thats 26kWh stored energy.

As max power is 185kW which assume for 130mph, actual range approx 8.5
minutes or about 20 miles.

All assuming 100% efficiency which of course is crap. I am in UK so someone
check my figures, but they don't stack up from where I am sitting.


Where are you going to do 130mph for 20 miles?

Efficiency overall charge to wheel should be around 90%.

I think you will find the range is cruising at 55mph, or 65mph, or an
averaged cycle.

I also calculated about 30Kwh is what it takes to achieve this sort of
performance.
