Tesla Roadster given extended 400 mile range

Electric cars are still on the periphery of becoming mainstream, but with Tesla’s latest update they are taking a step closer to practical success.
Despite the new Tesla Model S grabbing many of the eco-car headlines of late, company CEO Elon Musk has revealed the longstanding Tesla Roadster is being given a range extending boost.
Making the announcement via Twitter, Musk has confirmed the Roadster’s range for a single battery charge is being boosted to ‘almost 400 miles’.
He stated the update would “enable non-stop travel from LA to SF (San Francisco)” without the need for a lengthy recharge.

In order to make this possible, Tesla has taken the latest battery tech from the Model S and converted it for use in the new Roadster 3.0 package.
“Battery technology has continued a steady improvement in recent years, as has our experience in optimizing total vehicle efficiency through Model S development,” an official Tesla spokesperson said.

As well as introducing new battery cells – 31 per cent more efficient than their predecessors – the new Tesla Roadster is being enhanced through some aerodynamic and rolling resistance improvements.
The company stated: “Combining all of these improvements we can achieve a predicted 40-50% improvement on range between the original Roadster and Roadster 3.0.
“There is a set of speeds and driving conditions where we can confidently drive the Roadster 3.0 over 400 miles.
“We will be demonstrating this in the real world during a non-stop drive from San Francisco to Los Angeles in the early weeks of 2015.”
