Quoted from Wired.com's article posted two days ago:
Quote:
Today?s supercars are powered by batteries as well as internal combustion engines. The leading examples are the Porsche 918, the McLaren P1, and the Ferrari LaFerrari. At near or over $1 million a pop, each uses a hybrid powertrain.
It?s obvious why. Improving fuel economy may not matter to people who pay annual gas bills with the change under their sofa cushions. Improving performance does. Electric motors produce instant torque, which translates to terrific acceleration. When cost isn?t a factor, you can slap a motor on each wheel and really pump up performance. The 918 uses 6.8 kilowatt-hours of electricity to get it from zero to 60 in 2.5 seconds while maintaining a combined EPA fuel economy rating of 22 mpg. The LaFerrari?s 32-pound lithium-ion battery pack can get it to 205 mph. The P1 has one of the best Nürburgring times ever. Those are results.
