Tesla's top range a 'game changer'

Tesla Motors Inc crowned itself the maker of the world's fastest production car on Tuesday, saying a new version of its Model S all-electric sedan can accelerate from 0-97 kilometers per hour in just 2-1/2 seconds.

Tesla Chief Executive Elon Musk said the company will offer a larger upgraded battery pack for performance versions of its Model S and X vehicles that will extend range, while also allowing for super-fast acceleration.

The new 100-kilowatt-hour battery pack means the high-end version of the Model S sedan, called the P100D, will be the world's quickest accelerating car in production, the automaker said.
