Hi Paul, I never wished this to start an argument as we are all I hope avid EVers. My post was simply to show that a well designed drive train is capable of high mileages even when tugging around a heavy body and I totally agree with other posts that removing weight and lowering the CD will inevitably reduce the need for higher capacity battery packs. The Volt/Ampera has a 16kWh pack but only allows around 10.4kWh to be used for longevity and many are covering over 150,000 miles with little or no capacity loss as I believe the loss is above the allowed amount. As for proving the range, yes you need to drive steadily but it is an art many EVers develop naturally and this forum link https://speakev.com/threads/50-mile-club.304/page-11 will show that it is exceeded regularly.
What has surprised me is that my Volt/Ampera exceeds the range efficiency of my Lotus Elise EV which only weighs a tonne although is using an older drive train which uses the original gearbox fixed in third..

No they don't. 30 to 35 miles on battery. You would have to prove that, Of course the i-MiEV will go further if you drive 40 MPH. I was speaking of normal driving.

Volt/Ampera's regularly do more than 50 miles on their 10.4kWh battery packs and that includes dragging round a backup four cylinder engine in a steel chassis. -------------- next part -------------- An HTML attachment was scrubbed...
