Turns out Toyota was a bit conservative on its power claims.
Since we first had our first chance to digest all the specs of the new Toyota Supra, two numbers stood front and center: power and torque. Toyota promised the car’s 3.0-liter turbocharged inline-six engine produces 335 horsepower and 365 lb-ft of torque. Thanks to Car & Driver, its actually way more powerful than that.
After they strapped down the 2020 Toyota Supra to an all-wheel drive dyno in Michigan, the numbers rolled in. At its peak, the Supra put down 339 horsepower and — wait for it — 427 lb-ft of torque. At the wheels. Toyota claims 335 horsepower and 365 lb-ft of torque at the crank, which makes Car & Driver’s dyno results a big difference.
As a rule of thumb, most cars lose about 25 percent of their horsepower through the drivetrain before actually reaching the ground. However, it’s worth stressing that each type of car, and even each individual car, is different. Even leaning as conservative as 10 percent power loss, the new Supra produces around 370 horsepower at the crank. That’s extremely close to the 2019 BMW Z4 M40i’s quoted 382 horsepower figure.
What will tuners achieve?
Car & Driver managed to launch their Supra to 60 mph in just 3.8 seconds. On top of that, the car ran the quarter-mile in just 12.3 seconds at 113 mph.
Those are already impressive figures, but what happens once tuners unlock the car’s full potential? It looks like we may be in for a new age of ludicrously powerful Supras, a status the A80 MkIV model achieved in the 1990s. And you know what? I absolutely can’t wait to see how much power a tuned version can actually make.
Now, this is just one car. However, given BMW’s B58 engine has been around for a few years now, it’s likely the other Supras make similar power to this one.
