It may have been nearly three years since the Tesla Roadster was discontinued, but it appears the company that built it still has great plans for its first production car. To that end, Tesla has announced a retrofit 3.0 update package that applies the knowledge gained from its newer Model S, helping the Lotus Elise-based electric sports car achieve a predicted 40-50% improvement on range.

Tesla is confident that in certain speeds and conditions, the Roadster 3.0 can travel over 400 miles (640 km). It is so confident, in fact, that it will prove the quoted range is achievable through a non-stop drive from San Francisco to Los Angeles in the early weeks of the new year.

The most significant addition is a new 70 kWh lithium-ion battery pack, with its 6,831 cells each storing 31% more energy than before. A new aerokit will also provide a 15% decrease in drag, bringing the total drag coefficient down to just 0.31 Cd. Added to that, there are new tyres with 20% lower rolling resistance, while improvements in the wheel bearings and residual brake drag drop the overall rolling resistance still further.

Owners can upgrade their Roadsters in the spring once the new battery pack has finished its safety validation, and Tesla assures that it will continue to improve the Roadster in years to come. It’s an interesting time for Tesla at the moment, certainly on our shores, what with reports of it being interested in bringing cars into Malaysia if tax incentives were reintroduced.
