Video: Tesla Model S On The Dyno
In the world of performance cars, the dynamometer (or dyno for short) is a tool used for measuring the horsepower and torque of a vehicle. Usually this is used for tuning purposes, but some people just like to brag about how much power their car does (or doesn’t) have. We’re surprised it took so long, but someone finally put their Tesla Model S on the dyno…and the results are predictably awesome.
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…
