nice concept. Its good to see they can actualy go a decent distance. Unfortunatly, with a price above 100k, it may save gas, but not money. Its one of those "if you can afford it, gas isn's a problem" things.

I wonder if the power train is lighter than a standard motor. I would believe almost 7000 batteries would weigh a lot.

yea, but the prius is a hybrid. this is a full electric. the prius just has an electric motor that is ran off the alternator and a standard car battery. It works alongside a gas engine.

that sh*t is bananas! 0-60 in four seconds. too bad it will be a long time before it is affordable.

I read a bit about this on slashdot... shortly after reading about a fire on an airplane caused by a lithium ion battery. It would be an awefully impressive light show if one got in an accident. It would probably leave a pretty good crater in the pavement as well.

get it to sub 30k in 4 years and i'll get one out of college. I relly like how they are trying to make elecric cars more apealing now. my friend drove a prius, and he got sick of people calling his car the toyota "pris". He sold it, unfortunatly for a miata.

as for what bobski said, yea, theres quite a bit of potential energy there, but there is just as much energy in a gas tank. it takes heat and fire for a battry to explode, but if it did, you wouldnt want to be around it.

IIRC, it has less to do with the stored electrical energy and more with lithium's reactivity and combustion temperature.
Over-charging and/or shorting the output can cause a cell to overheat and catch fire or explode. A cell can short internally if physically damaged... Say in an accident?
Once the lithium is on fire, it will apparently strip the oxygen out of water to keep burning. Foam doesn't work well because of the high heat, so they (fire departments) tend to go for containment and simply let the fire burn itself out.

If you think a prius has a standard car battery and an alternator...you are the one that needs a lesson in what a hybrid is. The Prius has a 12 volt starter battery plus a 274 volt "battery array" (made up of 228 1.2-V cells) under the trunk.
Anyway, now that you understand there is a significant battery weight in the Prius, you can see why I mentioned it in the first place...if a hybrid equipped car weighs that much, imagine what the batteries would weigh on a full electric.

I saw an immaculate early-to-mid-90s black Lotus Elise in Indy over the weekend...they are simply gorgeous cars. Really aggressive, beautiful styling. When I lived in Chicago I used to park right next to an early-90s Elan, a cute little 2-seater that comes with a twin-cam, turbocharged Isuzu engine...I'd LOVE to have a Lotus someday.

I saw a red Exige and a red Esprit driving around after the F1 race this year. Both looked excellent.

The company's info says that their roadster is built at the Lotus factory along with the IC-engined cars. Makes sense, not having to yank-out the regular powertrain. Also, it appears that there are some changes to the body's appearance, again rightly done DURING assembly, not after.

Doesn't sound like a hack up job to me, other than that the body wasn't originally designed with electric propulsion in mind. I've seen similar "cobble-up jobs" done by "big name" auto manufacturers (cough, GM, cough).

For example, 1) the 1975 Chevy Monza was originally going to have a Wankel engine, but 6 months before intro, it was dropped (poor fuel economy and difficulty in meeting the brandnew 1975 emissions requirements) and replaced by a line of "normal" IC engines. Proof? It was a major service pain in the rear on those cars with the small V8 to replace two of the spark plugs that ended up inaccessible down in the engine bay. 2) The use of the 2.8L Citation V6 engine in the 1982 Camaro and Firebird. When the engine (which was designed for transverse mounting) was put in longitudinally, there were two "slight" problems- the distributor got crammed back against the firewall, making adjustment a MAJOR task, requiring a specially shaped adjustment tool to get to it for timing adjustments, and due to lack of stiffness in the interface with the transmission, two "stiffening rods" had to be bolted diagonally from the block to the tranny. And 3), the shoehorning of that same 2.8L engine into the Fiero to give it some measure of guts. Instead of installing the high-output version of the Quad-four engine (Oldsmobile property at that time), Pontiac chose to install the 2.8L V6, which just like the Monza 15 years previously, had a sparkplug issue- in this case, you couldn't get to the entire friggin' frontside sparkplug bank, as the firewall was right in front! Plugs had to be changed blindly, by feel alone. D-oh!

That 2.8 gets my vote for one of the worst engines I have ever driven or worked on. It was pure junk! My stock auto DX smoked my friend's manual V6 firebird. That thing was junk!

There are many problems with electric cars. I do not see them as the answer to replacing ic engines. Firt problem is energy density. You have enough energy in a reasonable volume of gasoline that only weights a few pounds to move people and a car a hundred miles. In an electric car the same energy takes up massive volumes and weighs a ton. Second, electric wehicles are not more environmentally friendly than internal combustion engines. it is just a different form of pollution that is being generated. Less smog in urban areas, but what do you think it takes to generate the electrical energy to recharge those batteries? it deestroys ecosystems and sometimes you uses petroleum products to make electricity. Then the battery technology isn't that great. batteries, once used up, have hazardous chemicals. what happens when millions or people are trying to dispose of old batteries every month?
I'm not claiming to have the answer, but i think that current research into enymatic processes that make ethanol out of natural biofuels is the more immediate answer if we want to keep using large IC engine vehicles. Or we could just all start riding bicycles to get around. Humans have the best efficiency at converting naturally supplied bio-mass into energy!

What we need is just a different kind of hybrid... One that steps away from the typical direct drive train. I would like to see a car using a small gas turbine with an electric transmission - the turbine is only connected to a generator while the wheels and mechanical accessories (power steering, A/C) are driven purely by electric motors. Train locomotives use a similar system, but with a huge diesel engine instead of a turbine.
Storing energy in batteries is what's so inefficient. The batteries would serve as storage for regenerative braking and supply power for sudden acceleration until the turbine spools up.
