AutoTech Video: We Drive Elon Musks Personal Tesla Roadster Sport The CEO’s Roadster came fully loaded with all the carbon fiber you could dream of — which it needs to keep weight around 2,700 lbs. The fully electric car has a 990 lb battery that delivers 215 kW of power. It’s capable of propelling the Roadster to a supercar-fast 0-60 mph in only 3.7 sec. Not only is the Roadster fast, but it also has an enormous range of 245 miles. A fully charged battery stores 56 kWh of electric energy (the Volt’s battery stores 16 kWh). During hard testing in the mountains we clocked 165 miles before the low battery warning light came on. Considering our driving, it’s hard to believe Top Gear only made it 55 miles.
