TESLA Motors announced its prototype “Roadster 3.0” package, which Roadster owners will be able to purchase in the future to update the battery pack, aerodynamics, and tires of their 2008-2012 Tesla Roadster electric sports cars.

Tesla chief executive officer Elon Musk said the updates are likely to improve the Roadster’s rated range 40 to 50 percent, from 393km to nearly 644km.

Tesla stated in a blog post: “There is a set of speeds and driving conditions where we can confidently drive the Roadster 3.0 over 400miles (644km).”

“Battery technology has continued a steady improvement in recent years, as has our experience in optimising total vehicle efficiency.

“We have long been excited to apply our learning back to our first vehicle,” said Tesla.

The new battery cells have 31 per cent more energy density, boosting battery pack capacity from 53kWh to 70kWh in the same form factor.

Modern computational methods with an add-on kit were used to improve the car’s aerodynamic profile.

Tesla expected that the aero kit reduce the car’s drag coefficient by about 15 percent to 0.31. The coefficient of rolling resistance of the new tyres will be 8.8kg per ton, down from 11.0kg/ton for the Roadster’s original equipment tires.
