Well, if you're the type of person who has "6,800 lithium-ion laptop batteries lying around", you probably don't concern yourself with how your car looks.

January 29, 2000 -- AC Propulsion' s tzero out-accelerated a Ferrari F355, a new Corvette, and a Porsche Carrera 4 in a series of impromptu 1/8 mile drag races held last weekend at Moffett Field in Mountain View, California, and at Calstart' s northern facility at the former Alameda Naval Air Station. The tzero was driven to the Bay Area from southern California last week. That journey spanned more than the geographic distance between those two areas, it spanned two cultures as well. Hot rodding, coming from the garages of Los Angeles, and high tech, growing from a garage in Palo Alto, are combined in the tzero.
The tzero is a silicon hot rod. It starts with the hot rodder's holy grail, horsepower - 200 of them. But the tzero harnesses the power with 120 IGBTs, equal to 7200 square millimeters of silicon-based control. The result is acceleration to 60 mph in 4.1 seconds, efficiency equivalent to 70 mpg, and emissions equal to zero. The tzero is an electric car.
The trip to Silicon Valley was planned to demonstrate the tzero to entrepreneurs and investors interested in the concept of a high-performance, environmentally-sensible, silicon-intensive automobile. As word of the tzero visit spread, the planned demonstrations took on an edge when a Ferrari-owner challenged the tzero to a race.
The race became reality when both Moffett Field and Calstart made their facilities available for the politically correct contest of speed. Saturday, January 22 dawned bright and sunny and an eager group of exotic car owners, high-tech gurus, venture capital investors and electric car enthusiasts gathered along the 4000-foot north taxiway at Moffett Field. Cones were set to mark the start and finish lines, and the tzero, with AC Propulsion vice-president Alec Brooks at the wheel, pulled up to the start line and sat silently. The Ferrari made glorious sounds as Rick Schick, a race car driver assigned to drive the Ferrari for the event paced the high-strung Italian thoroughbred up and down the track, warming its complex internals with nervous blips of the throttle and heating the tires with sudden burnouts. Finally the race was on. Immediately the crowd saw what it had not expected to see. The tzero leapt ahead at the start. The Ferrari' s 32-valve, 4-cam V8 engine screamed its delicious song in vain effort against the mute power of the tzero' s 120-IGBT-fed 3-phase induction motor. The spectators gasped at the sight of the tzero driving away from the automotive icon from Modena. At the end it was tzero by eight car lengths.
A Corvette C5, the newest example of American V8 muscle from Chevrolet stepped up to defend the honor of combustion power. Considered opinion had the Corvette, with its large displacement, high torque V8, putting up a good fight in the short 1/8 mile sprint. But against the tzero, the result was the same, proving in equally convincing fashion that American brawn fares no better than European sophistication against the tzero' s combination of light weight, high-current lead-acid batteries, and electric propulsion.
More races were run.
Different drivers wheeled the tzero. The result stayed the same. A Miata driver, unfamiliar with high power levels, got into the tzero and immediately blew away the Ferrari. She wants a tzero now. The Ferrari owner took a turn and was astounded by the continuous surge of smooth power. A newspaper reporter who arrived in an Escort allowed himself to be talked into driving the tzero and he beat the Ferrari. An investor from Sweden, after one victorious run in the tzero decided make a second run when challenged by his friend and investing partner who was proudly driving a brand new Porsche Carrera Cabriolet. By now everyone was surprised when the tzero lagged behind. Was the tzero battery dead? Was it collusion between two friends? Neither actually. The tzero inadvertently ran the whole race with its hand brake on, and the Porsche won by seven car lengths.

We have 12 laptops in the office, and in 3 years, all the batteries but one have died (they're Dells, and the Dell warranty doesn't cover the battery); and they aren't cheap to replace.
To replace all 6800 batteries every 2-4 years would be an expensive proposition (unless they can come up with a more reliable battery).

Hydrogen-based vehicles ARE electric vehicles.
The atomic bonds of H2 gas are just much more efficient at storing electricity than those weak ion based things we call "batteries".
The "Fuel Cell" is just an electric power source that is much more efficient output/weight.

However, with the single-gear Tzero's engine limited to just over 100 m.p.h. at 13,300 r.p.m.'s, it will never win an oval-track race against those supercars.
Unless of course you purchase the Scotty model, which comes with a guy in a red shirt (who surprisingly doesn't die) who rides shotgun, takes requests/orders from the driver to improve performance, whines about how the (di)lithium crystal batteries won't take the stress, then after a few tense seconds gets the car going 30 m.p.h. faster than it's rated to go.

Actually, the main reasons electric cars are not more popular are:
1) Lengthy refuelling time 2) Limited cruising range 3) Cost is not competitive - either the vehicle is prohibitively expensive (as in this case) or the batteries need to be replaced after a relatively small number of charge cycles, and the cost of electricity to charge the vehicle is not competitive with gasoline or diesel.
Solve all of these problems at the same time, and you will be wealthier than Billy G. (And less resented for your wealth) I won't hold my breath though, barring some revolution in battery technology, I put my best hopes for an alternative energy vehicle in fuel cells.
It has long been possible to get good acceleration out of an electric car, I remember a 1970's popular science article describing an electric vehicle with regular lead acid batteries that used an energy storage flywheel that recovered braking energy and fed it back into the transmission when you hit the accelerator for quick takeoffs. While you were idling at a stoplight, the battery would gradually be topping up the flywheel velocity, ready for a jackrabbit getaway on the green light.

Not only is the tZero a sporty little electric car with amazing acceleration, it can also achieve reasonable mileage and range using their hybrid range extended trailer. There are links in the AC Propulsion white papers section regarding the range extending trailer. Also, a link to a PDF
With this thing attached the car it gets a combined 40 MPG (highway driving at 100kph/60mph) and a range of around 380 miles. Not bad for a sports car. Another cool feature of the trailer is that it has a linked steering system; it's not a freewheeling trailer, rather the trailer wheels move with the car steering. This makes things like backing up (parallel parking and the like) much easier for those without experience towing a trailer.
Neat little car.

It says it costs about $3000 to replace the batteries, and it should be done every 20,000 miles.
Of course, that $3000 buys 1500 gallons of gasoline at $2/gallon, and if you're averaging 20 mpg you can go 30,000 miles.
So the gas car still wins, and we haven't even factored in the cost of the electricity to recharge the Tzero.
The Tzero might do significantly better in Europe, but that depends a great deal on how much electricity costs there.
