    Lighter than the original version by 500 lb (230 kg), the lithium-ion conversion goes from 0–60 mph (0–97 km/h) in 3.6 seconds. The single gear ratio limits the car's maximum speed to just over 140 mph (230 km/h) at 13,000 rpm with proper gearing, though it has never been tested at greater than the electronic limit of 105 mph (169 km/h).
