Tesla S gets souped up speed

Electric carmaker Tesla got gearheads buzzing this weekend with its announcement of a tweak to its Model S luxury sedan to give it super speed. The souped-up version will go 0-60 mph in 4.5 seconds and get about 320 miles per charge.

Green Car Reports has more on the specs:

The sportier version features the same 85 kilowatt-hour, 300 miles-per-charge battery pack found in the 2012 Model S Signature series.

“That’s quicker than a [Porsche] 911 [Carrera],” joked [Tesla CEO Elon] Musk. “Not bad for an electric luxury sedan.”

In fact, it’s better than some of the gas-powered cars in its class, including a few that Tesla fans say look remarkably similar to the Model S:
