700HP Lightning GT electric car available for pre-order




The electric sports car segment is about to heat up with the announcement that UKís Lightning Car Company is now taking pre-orders for its all-electric GT ahead of a scheduled launch date in early 2009. We first reported about the Lightning GT in June of last year but since then the carís design has been given a total revamp and final production specifications have been confirmed.

Powering the GT is a new 700hp electric powertrain featuring nano titanate battery technology, which is enough to propel the car from 0-60mph in a flat four seconds and take it a top speed of about 130mph. The electric drive system, dubbed Hi-Pa Drive, packs four permanent magnet brushless motors developing at least 120kW in each wheel and features full traction control and regenerative braking on all four wheels independently.

American rival Tesla Motors has had some major issues with the transmission system in the Tesla Roadster in months following up to their planned release date, however Lightning should have no such problems. Due to power being developed separately in each wheel, there are no gearboxes, differentials, axles, drive shafts or propshafts in the Lightning sports car.

One of the key benefits of electric vehicles is that they have maximum available power at the wheels at any speed, unlike a petrol engine where maximum power is only obtained high up in the rev range. Officials claim charging the batteries for just ten minutes will provide up to 250 miles of driving, and at current prices driving one mile will cost just 2.5 cents.

To save weight, the carís body is made from carbon fibre and Kevlar, and even with the full array of batteries on board the GT has a near ideal weight distribution of 48/52 front to rear. The car is also available with luxury items such as air-conditioning, satnav, and full leather trim.

I don't like the idea of independent motors. What happens if I stomp on the "gas" and one motor delivers less power than the other side? Do I fly into a wall?

I suspect that this car will be released as soon as the software they did those 3D renderings in is out.









(NOTE: Renderings done in Duke Nuke 'Em Forever, due out any day now)

I'm assuming it would have an electronically controlled differential or something similar to retain symmetrical power delivery.

wasn't one of the first cars ever made an all wheel drive where electric motors were connected to every wheel?

With 700hp it seems like it should be capable of way more than 130mph. Maybe the batteries run out by then.

It has no transmission, so you get one speed. The fact that it can do 0-60 in 4 seconds AND hit 130mph with one gear ratio is very impressive.

I think the charge time and range is more impressive.

10 minutes of charge for 250 miles? I'm guessing they mean 10 hours unless they re-invented the battery...that is still outstanding. But, once again, I'll believe it when I see it...

I think it's possible if you sap the entire powergrid in your neighborhood

That is awesome. I've been following this car for a while as my dad is moderately invested in the company that produces its batteries, Altaire Nano. Awesome, awesome tech.

If they're using the Altairnano batteries, then yeah, the individual cells can be charged in 10 minutes. But you'll need 600V service run into your garage to actually charge the umpteen thousand cells in the car in 10 minutes.

"HiPa" means the motors are from PML. PML did a concept hybrid Mini using those motors with 640hp that got something crazy like 80mpg.

I really don't want to know what this thing is going to cost. It'll be approaching midrange 6 figures, easily.

I'd be willing to bet they are coupled together at least by the control system ensuring that doesn't happen. There are too many lawyers out there...

Also, last I heard Tesla no longer has transmission woes since they decided to dump the 2 speed tranny and use a sturdy reduction gear (one speed).

That's an easy problem to fix, as it's been done with motors running conveyors for decades. But you also have to keep in mind that you don't always want both running at the same speed, or it would be like a locked rear end.

Not crazy about the rear of the car, what with the insane blindspot, but I welcome any new electric cars out there. Overall not bad looking, but price and lack of a running prototype will likely be the killers.

Good point.

That makes a seemingly simple design a bit more complex...
