Re: [EVDL] '83 Chevy Impala...?

More like 3800 pounds. I had an '85 Impala, remember
these are full-size Chevrolets and not "down-sized"
models as the rest of the Chevy lineup went to,
although they were a bit lighter than some previous
full-size Chevrolets. This design went to 1991, then
in 1992 they went to the new aero style.

reference:
http://www.caranddriver.com/features/2042/10best-of-1983-151-chevrolet-caprice-classic.html

1983 Caprice V8: 3900 pounds. The V6 wasn't a lot
lighter, it was basically 3/4 of a ~450 pound V8
engine.

A lot of those vintage Caprice/Impala had soft springs
and won't handle much extra weight, but it is quite
easy to fit stronger springs to these models.

If you start with a lighter car, you won't have to
purchase as many batteries to get the same range &
acceleration. But if you need lots of room with
relatively good handling, this is a good car. It has a
traditional frame and you should be able tuck away 30
or so 12V batteries in its vast confines.

Re: [EVDL] '83 Chevy Impala...?

Guys,

Thanks for the straightforward, detailed responses! I'm still not
sure about this car as a candidate as I would at least have to tighten
the suspension way down to be happy driving it regularly. One really
good thing it has going for it is that it's not super tall and narrow
like some of the modern economy cars. I really hate body-roll. { : p
Also, it's got surprisingly good git-up for such an old motored and
heavy car.

Maybe I need to borrow it for a week and see if I can get excited
about driving it full-time-ish.

Thanks again for the input,
Trot, the never-sure, fox...
