Retro Thing: This Vintage Electric Car Could Be Yours
About 2,300 CitiCars was produced between 1974 and 1977 in response to the OPEC oil crisis. It had a top speed of around 50 mph and a maximum range of 40 miles per charge - fairly impressive for a vehicle with a 3.5 HP motor powered by 48 volts from a stack of eight lead acid batteries. http://www.retrothing.com/2010/09/efftee...-run-seems.html
I am assuming that was a brainchild of Clive Sinclair. he was (and I guess still is) famous for amazing, innovative products. But unfortunately he didn't always think about the "side effects." His PCM (PWM? - I forget) amplifier (more power per cubic inch - by far - than anything else available) reputedly jammed radio and TV reception for several yards in every direction!
The problem with these cars is that the distance is a bit limiting and while they may be cheap to run, if you follow the power point back to its source you will probably find a coal burning electric station at the other end.
Even the Tesla above is very pricy but on Topgear they struggled to get half the distance they claimed. Also to fully charge it takes 16 hours off a standard GPO (4 hrs with a special fast charger) so they are not overly practical. I imagine to get the claimed distance of these new electric cars coming out you must not drive up any hills, not use the air con, don't use rapid acceleration and go on a diet.
