The Tesla Model S EV will start at $49,900 after a $7500 tax credit and 440-volt charging will be available. That base price is for the 160-mile range pack; there will also be a 230-mile range pack and a 300-mile range pack. It goes to 60 in 5.6 seconds and can fit 5 adults and 2 children. The Model S powertrain includes a liquid-cooled 9-inch motor, floor-mounted battery pack and a single-speed gearbox, delivering effortless acceleration, responsive handling and quiet simplicity — no fancy clutchwork or gear-shifting required. Model S costs as little as $4 to fully charge. Will start production mid 2011!
