Tesla engineers developed the specifications for the new gearbox and provided them to BorgWarner. The new powertrain delivers about 30% higher motor torque on a single gear ratio, and it achieves a 10% higher EPA combined range.

The Roaster torque will be increased to 280 foot-pounds, while the EPA rated range of the car will increase to 244 miles, up from 221 miles. The quarter-mile time for the car is now in the 12.9 second range.
