Electric Car Faster Than A Ferrari or Porsche
jumpeel writes "CNN's Business 2.0 has photos and video of a Silicon Valley-made electric car with a 0-60 acceleration rate that's faster than a Ferrari Spider and a Porsche Carrera. From the article: 'In fact, it's second only to the French-made Bugatti Veyron, a 1,000-horsepower, 16-cylinder beast that hits 60 mph half a second faster and goes for $1.25 million.' The X1 is built by Ian Wright whose valley startup WrightSpeed intends to make a 'a small-production roadster that car fanatics and weekend warriors will happily take home for about $100,000 --a quarter ton of batteries included. The X1 crushed the Ferrari in an eighth-mile sprint and then in the quarter-mile, winning by two car lengths.'"

Any engineer worth his salt can tell you that electric motors put out a hell of a lot more torque than gasoline engines. Gasoline engines are restricted by the tolerances of their mechanical parts, even if the engine is capable of producing more horsepower under load. That's why raw horsepower figures are often a poor indicator of a vehicle's acceleration.
Diesel Locomotives were making use of this fact long before the electric sports car showed up. By transferring the power from the Diesel Engine to an electric transmission, modern locomotives are able to smoothly apply power curves of well over 300KW without any of the slippage or rough starts associated with the Steam Engine.
Honestly, this entire story isn't anything new. The TZero was trouncing expensive sports cars long before the X-1 was introduced. The only difference I can see here is that the owner of the X-1 appears to be looking to build a replacement for Formula-1's rather than creating a slightly more practical Porche type of vehicle.

I've got a vehicle that quick. It'll do 0-60 in 3.5, I've gotten 50MPG cruising on the highway at 80MPH (admittedly with a little tailwind), it goes about 200 miles on a tank of gas, and it cost me $2000 used.
It's a 600cc sportbike.

The solution allows at least 350 highway miles per charge and can be fully recharged in 5 minutes or less.
As far as I know, no current or on the horizon electric-only system can do this. Hydrogen / fuel cell are close, but that is something that just cannot be done with chemical batteries in the mass market (I have heard of research into areas of fast charging, but I know I don't want to have to stand near an electric supply that is transferring at over 6 MW (10 gallons in 3 minutes of gasoline is just over 6.3 MW equivalent energy transfer).

"II. Electric Vehicles
Electric vehicles are incapable of replacing more than a small fraction (5 or maybe 10%) of the 700 million internal combustion engine powered cars on the road due to the limits of battery technology. Dr. Walter Youngquist explains:
. . . a gallon of gasoline weighing about 8 pounds has the same energy as one ton of conventional lead-acid storage batteries. Fifteen gallons of gasoline in a car's tank are the energy equal of 15 tons of storage batteries. Even if much improved storage batteries were devised, they cannot compete with gasoline or diesel fuel in energy density. Also, storage batteries become almost useless in very cold weather, storage capacity is limited, and batteries need to be replaced after a few years use at large cost. There is no battery pack which can effectively move heavy farm machinery over miles of farm fields, and no electric battery system seems even remotely able to propel a Boeing 747 14 hours nonstop at 600 miles an hour . . .
Some promising research into new battery technlogies using lithium is being performed, but even the scientists at the forefront of this research admit, "We've got a long way to go."
Assumming these problems away, the construction of an average car also consumes 120,000 gallons of fresh water. Unfortunately, the world is in the midst of a severe water crisis that is only going to get worse in the years to come. Scientists are already warning us to get ready for massive "water wars."
Thus, the only way for us to replace our current fleet of gas-guzzling SUVs with fuel-efficient hybrids or electric vehicles is to seize control of the world's reserves of both oil and fresh water and then divert those resources away from the billions of people who already rely on them.
Even if were willing to undertake such an endeavor, the problem will still not be solved due to a phenomenon known as "Jevon's Paradox," whereby increases in energy efficiency are obliterated by corresponding increases in energy consumption.
The US economy is a good example of Jevon's Paradox in action. Since 1970, we have managed to cut in half the amount of oil necessary to generate a dollar of GDP. At the same time, however, our total level of oil consumption has risen by about fifty percent while our level of natural gas and coal consumption have risen by even more. Thus, despite massive increases in the energy efficiency over the last 35 years, we are more dependent on oil than ever. This trend is unlikely to be abated in a market economy, where the whole point is to make as much money (consume as much energy) as possible." - http://www.lifeaftertheoilcrash.net/SecondPage.ht
Here in the USA, most of your electricity comes from coal. We usualy use electricty to generate hydrogen. If we ever move to the "Hydrogen Economy" without some major production changes, we would be better off just creating a coal burning car.
I hate to break it to you, but the Hydrogen car is not about the environment. Sure, it's a nice side-benefit (large power plants are more efficient, hydro and nuclear help reduce pollution, etc.), but the real reason is economics. Oil is quickly approaching a price point to where it is no longer economically feasible to power our transportation infrastructure off it.
Shifting to hydrogen would change the economic equation, and free our infrastructure from a costly choke point. All the power would be consolidated at the power plant level where the government can more easily regulate the infrastructure and provide incentives for companies to provide cheap power.
I hate to be the bearer of bad news, but economic considerations tend to apply a lot more pressure than the toothless protests of environmental protection groups.
