When the Tesla S Plaid was introduced, its official power rating raised a few eyebrows. Does it really produce 1020 horsepower? Let’s find out.

Here’s the first thing we liked about this video from Uptown Autosport of Mirabel, Quebec: It’s short, sweet, and it gets straight to the point. As you know, here at Mac’s Motor City Garage we like our technical info the same way: without embellishment. At one minute and 44 seconds, the video doesn’t take any more of our time than it needs.

Next, they addressed this question with the right piece of equipment: An Australian-made Mainline Prohub AWD chassis dynamometer. The many types of engine and chassis dynos all have their pros and cons, but a four-wheel dyno can handle the Tesla Plaid’s twin front/rear motors and all-wheel-drive, while the hub-drive system eliminates one pesky variable: wheelspin. And with 1000+ horsepower on the menu, that’s bound to be an issue.

If you’ve spent much time around dynos, you know that testing high-output machines  usually involves a considerable amount of noise, stink, and smoke filling up the shop, but thanks to the Plaid’s all-electric powertrain, this dyno run was eerily silent and  drama-free. We could call it anti-climactic, except for the result: 1067.3 horsepower and 878.6 lb-ft of torque, comfortably exceeding Tesla’s official number. Which certainly helps to explain how a 4800-lb, four-door luxury sedan can run the quarter-mile in the low 9-second range at 150 mph. Video below.
