1 Gear is All You Need
Tesla Motors, makers of the much talked about Tesla Electric Roadster, has just announced that it has selected BorgWarner to produce the new Roadster 1-speed transmission (ratio of 8.2752:1, can go up to 14,000 RPM).

More Powerful and Efficient
The updated version 1.5 powertrain, which also includes a more powerful inverter and an enhanced motor design, will produce 30% more torque (to 280 foot-pounds) while also increasing the EPA rated range of the electric car by 10% to 244 miles (393 kilometers), up from 221 miles (255 klicks). The ¼ mile time for the car is now in the 12.9 second range.
