Is not every day that you have the chance to see an electric car tested on a dyno machine, but the guys over Dragtimes were the first ones to have the Tesla Model S Performance tested on dyno – as far as we know.
The end result is a pretty monstrous 388 horsepower at the rear wheels. The factory-stated horsepower is 416 horsepower, meaning this beast only loses 28 horsepower through its drivetrain. That’s a mighty astounding number considering the 2013 Viper GTS loses 80 horsepower through its drivetrain. That’s a 12.5-percent loss for the viper versus a 6-percent loss for the Tesla – mighty fine work, Tesla. Then again, Tesla has the advantage of having a direct-drive system and no traditional transmission to gobble up horsepower on the way to the wheels.
The Performance model is offered exclusively with the larger capacity 85 kWh battery and is priced at $87,400 or $79,900 if you deduct the $7,500 federal tax credit.
