The new '3.0 Package' for the Roadster, which is due to be offered to existing customers in spring 2015, features developments that are a product of the company's experience with its Model S saloon.
Key to the upgrade pack is the adoption of new battery cell technology that boosts the energy capacity of each by 31 per cent. This means the Roadster's battery pack now delivers approximately 70kWh, up from its previous 53kWh.
Revised aerodynamics deliver a 16 per cent reduction in drag coefficient, down from 0.36 to 0.31. This is achieved with a retrofitted aero kit, as opposed to major changes to the existing panelwork. Lower rolling resistance tyres, new bearings and tweaks to the brakes further serve to improve the Roadster's range.
The company estimates a 40 to 50 per cent improvement in range, compared to the original Roadster. In standard form it could cover 245 miles on a single charge; in 3.0 form expect it to cover around 370 miles.
