Video: Tesla Model S On The Dyno
Before we get into the dyno numbers, let’s talk about Tesla’s power claims. From the factory, the Tesla Model S makes 416 horsepower and 443 ft-lbs of torque, with a 0-60 mph time of 4.4 seconds. These are impressive numbers, but how much of that power actually makes it to the ground?
A lot, as it turns out. On the dyno, the Tesla Model S put down a substantial 386 wheel-horsepower, meaning that there is less than a 10% drivetrain loss between the motor and the ground. A traditional ICE engine sees between 15% and 20% power loss between the engine and the wheels.
It is also remarkable just how quiet the Tesla Model S is; most dyno videos feature a deafening roar which, while not entirely unpleasant, can be a bit of an annoyance. Really, really makes us want to get one of those Tesla powertrains for a project car…
