Tesla Motors Inc. is offering owners of the Tesla Roadster upgrades for their electric vehicles. For instance, Tesla is offering to upgrade the battery technology used in the Roadster, allowing it to provide 31 percent more energy than the original cells.
The upgrade also includes an aerodynamics kit, new tires and improvements to wheel bearings and brakes, which in total allows the Roadster to travel up to 400 miles. Tesla calls the upgrades collectively as Roadster 3.0.
Tesla said in a blog that it plans to demonstrate the new capability of the Roadster in the real world through a non-stop drive from San Francisco to Los Angeles in the early weeks of 2015.
Tesla launched the Roadster in 2008 and sold 2,500 units at $109,000 each. Since the Roadster was introduced while the world was suffering from a recession, Tesla also suffered from cost overruns and production delays that nearly sent it into bankruptcy.
The carmaker only reported a net income in the first quarter of 2013. Tesla chief executive Elon Musk said the carmaker will eventually offer a battery-pack up grade for the Model S, the only car in production.
