Acceleration

Stolen from Pistonheads... never mind TBs, this should improve my awful 0-64 ft times:

200 hp, 0-62mph in 1.785s.

So that is class 4 if I fit a Caterham-ish body and KumZZers?

More seriously, how long before we see a properly quick electric car on the hills?

I was just reading about that car too - video looks amazing.

Some of us have speculated about electric sprint/hillclimb cars - it's the perfect type of event for them because you only need a small battery. You could even make the battery "quick change" to further minimise size/weight. Reliability should be good as few moving parts and you can program the torque/power curve to whatever you like.

There was an electric Westfield at Curborough Marshall's sprint this year. It was one of the development cars for the proposed Westfield Electric race series that never got off the ground. As it was a prototype it had a number of things that could be improved such as where the motor was mounted - back of the axle in this case  so not ideal for weight distribution. The battery pack was also sized for a 20 minute race - that could be massively reduced for hillclimbs. Chatting with the owner, we reckoned it could be got down to 500kg without too much difficulty. I suspect in a single seater things could be further improved.

Is it wrong of me to like the idea of this  ?

Electric drive, a motor in each wheel and software control of power... I wish I'd thought of that.

Very little is new. Wheel hub electric motors came in around 1884   .
