Vectrix claims 68 mile range, but reading the spec sheet
(http://www.vectrix.com/Portal/1/Language/47/Page/16/Vectrix_Specs.aspx)
reveals that this is at 25mph. I'd say my lead-acid Force has a
realistic range of 35 miles for everyday use, but I'm sure I could
drive well over 68 miles at a steady speed of 25mph. So what's the
realistic range of a Vectrix?

I don't think they are doing anyone a favor by trying to sell vehicles
based on a range you won't really be able to get.

Sad to say, this kind of exaggeration has been a fixture of the EV world
since time immemorial.

THere are (or used to be) various standards for EV range testing - different
ones (figures) for Japan, EU, and US. These were promulgated in the 1980s,
IIRC, about the time that GM promised we'd be able to buy an electric
Chevette Real Soon Now. ;-) I've never seen any of them actually used for
computing advertised range.

I know there are people here who disapprove of legislation, but I think
Detroit's reaction to safety and emissions issues shows that until the law
requires standardized EV range testing (as it does for ICE fuel efficiency),
EV manufacturers are going to continue publishing fantasy-world range
figures.

The same argument can be made about federal MPG testing, which only
recently has tried to close the gap between 'test' numbers and
real-world efficiency:

The realistic range is probably around 40. It can be hard to fit a lot of
batteries in a small space on a scooter.

>From my 3 day experience I picked up the bike with 48 miles range I drove
14.5 miles up and down some challenging hills with some freeway topped out
speed. The hilly part was topped at about 35mph with lots of quick
acceleration. The few miles of freeway were at the 62mph top speed. The
distance meter read 19 miles down after the 14.5 miles. . I then charged &
it was finished charging very quickly. The manufacturer claims 80% charge
in two hours. I believe it. When I un plugged it had 52 miles on the
clock. Almost a day later I tried charging more and the batteries kept the
charge so well that the charger wouldn't charge anymore and shut off almost
imediately. I think the Vectrix is a very fine example of EV engineering.
