This is what I've been immersed in over the last 2 years. It's a street legal EV muscle car based upon an original electric city car made on the isle of wight in 1974.
Mine was one of the original prototype test vehicles for the British Electricity Council and is chassis number 003. Webster Race Engineering did most of the cage, tubbing, 9" axle and 4-link rear. It is a tiny thing.
That's the first elec car I've ever seen that I actually quite like!

Hello Pete. See you soon I hope? I need that Jaz bucket seat soon...
Cheers db!

That looks cool.
So what does it cost to 'fill it up' with electricity?
Had Npower set aside one of its cooling towers for your car alone?

No worries. Once Sywell is out of the way the only other car related gig I have is the NEC in November.
...and LOTS of concerts too!!
All the best.

Looks great Johnny!
Trying to work out 1870lbs, 500hp, 1000ft lbs with a 0-60 in 4..............but only 12ish seconds on the 1/4..........
Would have thought high 10s would be easy?
Calcs say it should be in the mid 9's!
Would also like to know what happened to the Charger.......??

I cannot say 9s at this stage because I have no idea how it will drive on the strip. It's v short and could be frisky. I need it to be at least a 12 sec car, but we shall see.......
It will be about 850kg in weight. 711kg without batteries or cabling.
Should be able to do 5 runs on full power between charges, or up to 50 miles of town driving hopefully.
Yep, still got the Charger - had it out this year a lot after a 2+ year sabbatical.
Impala sat in dry storage for the last 4 years with hardly any progress. It's next on the list after this leccy relic.
Glad you guys appreciate this project. Hope others will get it.

Very interesting, had me thinking for a while about how that might perform. That's a huge amount of torque to propel something so light and brick shaped, very likely to have some handling issues and then some.
Some thought's,
Assume it's direct drive? no clutch? Not likely to 60ft very well as you will be starting the motor from standstill , so it will take time for it to accelerate unless it breaks the tyres loose from the off which would probably result in a faster run if you could keep it under control.
Once the motor is turning at a decent RPM it's liable to pull like all hell, depends how far down the track you are at that point regarding the ET & trap speed.
Trap speed will probably be totally out of whack with the ET, way faster than it should be.
An electric motor will accelerate much faster than a piston engine can I would think, but it's starting from zero revs. If you were running it through some sort of clutch though, I could be a very different story....
More info please I'm intrigued!

A very interesting project More than a touch of Honda N360 about the body design.

Yes Blue, direct drive from the motors. The motors are linked via a coupling (they live in the trans tunnel) and then a custom 6" prop into the Ford 9" rear. The forget the gearing we went for but the 9" has a Spool and was built narrow for this car.
The motors are controlled by a digital controller, which acts like an ECU. Using a PDA we can plug in and dial in different power and throttle sensitivity.
The whole project was inspired by this White Zombie electric Datsun over in Oregon:
Gad you guys like it.

The motors will start in SERIES configuration with the voltage output of the controller (ECU if you like) at 320 volts (160v + 160v) and 1800 amps.
During a hard throttle run on the quarter mile – when certain parameters are met – the car’s controller will switch the motors in to PARALLEL mode. At this point the controller changes the voltage output to 160 volts and current 1800 amps. So parallel @ 1800A /2 = 900A @ 160v.

Gotcha, in that case this thing could really fly!

Can't wait to see that run.
If the estimated ET's are correct it should be interesting with that wheel base
Interesting thread. Thank you for sharing with us.
