Despite lacking a combustion engine, the Roadster Sport is by now means a slouch, launching from zero to 100km/h in just under four seconds.
The Sport model uses a hand-wound stator and increased winding density for lower resistance and higher peak torque.
Agility has also been improved with Yokohama’s Ultra High Performance tyres and improved suspension with adjustable dampers and anti-roll bars that will be tuned to the driver’s preference.
“This car can beat nearly anything in its price class – yet it is twice as efficient as compact hybrid sedans,” said Michael van der Sande, Tesla’s senior vice president of global sales, service and marketing. “If you refuse to compromise on performance or the environment, the Roadster Sport is your only option.”
The Roadster Sport starts at $128,500 in the United States, with Tesla offering the more than 1,100 people currently on the waiting list an option to upgrade to the new model.
The Californian-based company also plans to begin producing the all-electric, zero-emssion Model S five-passenger sedan in 2011.
