An anonymous reader writes: The biggest complaint about Tesla Motors' electric vehicles is that they're far too expensive for the average motorist. The Roadster sold for $109,000, and the Model S for $70,000. Chris Porritt, the company's VP of engineering, says their next model will aim for much broader availability. The compact Model E aims to be competitive with the Audi A4 and BMW 3-series, which both start in the low $30,000 range. To reduce cost, the Model E won't be built mostly with aluminum, like the Model S, and it will be roughly 20% smaller as well. The construction of the "Gigafactory" for battery production will also go a long way toward reducing the price.
