Updated 1PM EST 12/26 Tesla has announced its new Roadster 3.0 prototype which will improve the car in three ways: improved battery life; a new aerodynamic kit; and a wheel upgrade.
Tesla says its improvements will increase range by a predicted 40-50 per cent between the original Roadster and the Roadster 3.0 specification.
Firstly, Tesla says it has improved the efficiency of its original lithium ion battery by 31 per cent with a new output of 70kWh. Additionally a new retrofit aero kit will reduce drag by 15 per per cent while a set of new tires and upgraded wheel bearings will result in a further 20 per cent rolling resistance improvement.
The company says it will demonstrate the improvements with a non-stop test drive from San Francisco to Los Angeles in the early weeks of 2015.
