Tesla Model S Concept Not much details announced. It will be a full electric car like the Roadster. It may be built on an existing platform to save cost. Rumors of 440V fast charging system have been flying around. Different battery size will be offered (more capacity for more $$$). It's a 5 seater. And the concept has a 17in screen stuck on the dash. If it ever sees the day, it will cost around $60k. The Fisker Karma is a much more tangible prospect than the Model S. Fisker had been in a long legal battle with Tesla over industrial espionage and contract, etc... It won in Fisker's favor. The Karma is a PHEV like the Volt. It means that the electric car has a backup gasoline engine to run the electrical system. It can either be charged at home, or be filled up at the gas station. Electric car/hybrid car. The Karma's party piece is the design. The body was styled by Henrik Fisker, who has worked on some of the most beautiful cars in the world such as the BMW Z8, Aston Martin DB9 and the V8 Vantage. It also features a novel optional solar panel roof to charge the batteries. The price is much higher around $90k, but it's already sold out for the first year of production, and the car produces maximum of 408hp and a massive 959lbft of torque. The technological aspect is developed by California based Quantum Technology. There is also a convertible version previewed earlier this year.
