What is it?
The revolutionary Chevrolet Volt, a mainstream electric car that goes on sale in the US later this year and hits the UK in late 2011.
Based on the Vauxhall Astra platform, the Volt is a four-seat hatch powered by lithium ion batteries that can be recharged by plugging into the mains, or on the go by a 1.4-litre petrol engine.
GM is confident the Volt will be capable of up to 40 miles' range on a single charge, although accepts that heavy usage - such as climbing or high-speed running - will reduce that.
Although unlike every other EV, fluctuations in range don’t really matter, because the Volt can fire up its petrol engine to ensure there’s always drive to the front-wheels.
The electric motor is rated at 110kW or 150bhp, and delivers a healthy 273lb ft of torque, about the same as a 2.0-litre diesel.
The lithium ion battery pack is water-cooled and heated. Cooling is particularly important, because excess heat can kill lithium ion cells. GM is promising the battery pack will last the life of the Volt, which is interpreted as 150,000 miles.
Given the battery capacity and the Volt’s range, the engineering spec allows for 6000 full charge or discharge cycles, events that eventually will reduce the battery’s storage capacity to 70 to 80 per cent of what it was capable of when new.
What’s it like?
The most significant point is that the Volt is just like a normal hatchback to drive, with the added significant benefit of being very quiet.
We had a short drive on a simple, flat test circuit and found that the Volt steers, rides and handles in a very similar manner to the Chevy Cruze saloon. That means it’s more comfort-oriented than the sportier Vauxhall Astra.
Driving the Volt is very simple. With the ignition on, press a starter button and the dashboard lights up and bings into life, just like a PC. In the centre console there’s a PRND selector exactly where the gear-shifter is on a regular car, and in the footwell are two pedals: accelerator and brake.

Re: Chevrolet Volt
So your test was "We had a short drive on a simple, flat test circuit". It might be capable of 40 miles on its electric motor, as long as you don't want to go uphill or fast. It has no head room and the leg room of a Corsa and the price is to be announced. And your conclusion. should we buy one - yes. Someone normal might come to the conclusion that the answer should have been no. Limited range, no announced price but likely to high, poor passenger space

Re: Chevrolet Volt
Why did they have to develop a smaller, uglier, less spacious and more dated model? They could've put this technology in an Astra. Instead they built this ugly pile. Then again they could've also put this technology in a SAAB. But that would never do in the U.S. of A.
As with all other GM products, except SAAB, I won't be buying one.

Read tha article - the shape comes about after extensive wind tunnel testing to be as aerodynamic as possible + needs to be a saloon type shape to fit all the batteries in. It has been designed as a hybrid not a car adapted to a hybrid which dont work as well. Has to be reasonably small to keep weight down.
This technology cost a fortune to develop thats why it needs to put into a manufacturer that sells a lot of vehicles which isnt saab - no-one buys them. Hence Chevy in the US and Vauxhall over here.
I actually think it looks pretty good as far as hybrids go - far better than the ugly Prius + the Honda Insight.

Re: Chevrolet Volt
Is it that difficult to build an electric car? The trick is not building a car that works, it is getting it to the market at a price the market will pay. We dont know prices, but seriously doubt they can be sold at a remotely sensible price. Take a Prius as an example. It has all the same stuff in it (even if the principal is different) but a much smaller electric motor, and most importantly, a hugely smaller battery pack. And its those batteries that are the real cost. And yet it starts at nearly £20,000. With all those added costs a Volt would need to be nearer £30,000, and that as has been stated is for a car a size smaller on the outside and 2 sizes smaller inside. We know toyota subsidised the Prius at least to start with, but they are a hugely rich company. GM cant subsidise the Volt, as they dont have any money
Add to this that in the UK any large scale take up of 'charge at home' electric cars would put a huge dent the the tax take, and that would have to come from somewhere else, like road charging.
I think it is interesting technology, but for now until batteries get much much cheaper i think this is an answer to a question no one will be able to afford.

Re: Chevrolet Volt
Interesting to finally read a little more technical detail about it. 6000 charge cycles is a significant achievement: Apple make a big noise about their latest laptop battery being good for 1000 charge cycles. At one charge a day, or 40 miles per charge, that translates to a battery life of 16 years or 240,000 miles.
A shame though that it's a strict 4 seater and a size smaller than a Prius - that pretty much rules it out as being of interest to us as our main car, and I suspect it's going to be too expensive for a second car.

But it seems a bit daft to only have four seats - not exactly practical. The price will most probably be too expensive for most people, too. However, once the price of the batteries come down, the electric car could well be the way forward. We'll see when Renault introduce their models, along with Peugeot's BB1 and everything else that seems to be 'on the horizon'.

I'll just say hello all as this is my first post here.
If I understand it properly from the limited first report, it only uses the engine to charge the on-board batteries...so why is it necessary to use a relatively large 1.4L petrol engine only to charge batteries?
Wouldn't a smaller petrol engine be more efficient or even a smaller diesel?

Re: Chevrolet Volt
GM desparately needs the Volt to be a huge success, otherwise it could be curtains for the company. And by the looks of things the car deserves to do well. I hope GM pulls it off.

Re: Chevrolet Volt
A GM spokesperson was quoted last week, "...Chevrolet Volt may cost less than the expected $40,000 price tag..."
Giving them the benefit of the doubt, say $37.5k; which in the normal run of things would translate to a GBP35k OTR price.
