The World's Fastest Electric Car
Roland Piquepaille writes "In this review, Forbes.com looks at the fastest electric vehicle in the world, the tzero roadster built by AC Propulsion Inc. 'The tzero does 0 to 60 mph in 3.6 seconds, according to the company, and it does it on only 200 horsepower.' The company says it starts faster than a Ferrari F355. It also has a limited range of 280 to 300 miles at 60 mph on a single charge. The company expects a price somewhere between a Porsche and a Ferrari, but Forbes says it carries a $220,000 sticker price. This overview contains more details and links. It also includes a rendering of the Tzero. Please note that the Forbes article has a very different focus from the one mentioned in a previous Slashdot reference."
The picture on the website says 100 miles at 60mph and 0-60 in 4.1 seconds (still not slow).
100 miles at 60mph is nothing special nor is it anything good.
What about the world's fastest SOLAR-electric car?
The Nuna II, just won the World Solar Challenge, travelling 3000 kilometers in just 31 hours, averaging around 97 km/h.

What about the Tengo?
It gets 0-60 in about 4 seconds, and a top speed of 130MPH. That is certainly better than 3.6 and 60.

Not trolling... I just honestly don't know.
How are electrical cars more energy efficent than gas powered ones? We get the majority of our electricity from burning fossil fuels.
If we all convert over to electrical cars, will be not just burning more oil and coal in our power plants?
Where the energy-saving step that I am missing?

..the only reason that 200hp can push the car to 60 in ~4 seconds is because the thing is the size of a matchbox (look at the Gallery pics, the car is about as big as a gas pump :D). I suffered with an MR2 MkII for a couple of years, this thing looks 2/3 the size...good thing it only has an hour range, my legs couldn't take much more.

Electric motors, unlike internal combustion engines, can generate maximum torque at zero RPM. This translates directly into excellent off-line acceleration, impressive 0-60 times, and all-round high performance. Around-town driving in an electric car should give the impression that there's a much bigger engine due to our preconceptions based on internal combusion (thus, the comment "only 200 hp"). Top speed, however, will seem stunted in comparison to that available from an internal combustion engine because they generally produce increasing torque with increasing RPM (especially below 2000 RPM).

Do a Google search for "Honda DualNote". The DualNote is a rear engined hybrid sports sedan concept Honda created about 1-2 years ago. It has a rear-mounted 300hp V6 gas engine attached to an electric motor and multi-gear transmission and two electric motors on the front axle. It had a peak HP of 450 and could get 48mpg in normal driving. It was even featured in the PS2 game Gran Turismo Concept. Now that is a hybrid to drool over.
Considering that hybrids have to carry around 2 engines, a fuel tank and batteries, probably not for a long time.
Smart sell 100s of thousands in Europe, but haven't even bothered bringing their amazing 2-seaters to the States, where the bigger, heavier and unaerodynamic a vehicle is the more successful it seems to be.
Smart used to just make the sub-sub-mini coupe, (which I'll admit is a bit odd even though I drive one) but now there is the sporty roadster, a very pretty car indeed which gets better economy than the Prius from it's turbocharged Mercedes engine, and costs less than a mid-range Ford. Pop over to www.smart.com and see what you are missing.
