Another 2020 Toyota Supra Proves Its Mettle On The Dyno, Tuners Rejoice!

There’s a new video showing the new Toyota Supra putting out significantly more power than the official ratings, which kind of cements the rumors that have been circulating for the past few months.

Evidence of the Toyota Supra being more powerful than advertised first landed in late May, with one of the first examples revealing that it produces 339 HP and 427lb-ft (578Nm) of torque at the wheel during a test from Car&Driver.

Car Throttle took a UK press car to the dyno in order to see just how much power there is under that sculpted body and quelle surprise, it also pushes way bigger figures than it’s supposed to.

This car put out 376 HP and 410lb-ft (555Nm) of torque – probably at the crank, but the video doesn’t make it clear- over the official 335 HP and 364lb-ft (494Nm).

Since the news first broke that BMW would provide the hardware for the new Toyota Supra, experts in the tuning world knew that it would be very easy to extract more horsepower from the reborn Japanese icon.

Surrey Rolling Road, which tested Car Throttle’s Supra, basically confirmed that the B58 engine used here and in various BMWs is, as always, performing above its official ratings. They also found that the engine in the Supra is a bit restricted at the top of rev range, which means the tuning potential is even bigger than you might think.

How big? Charlie from Surrey Rolling Road says that a BMW M140i, which uses a previous version of the same engine, can, with a remap and an exhaust, comfortably push 450 HP and reckons that the Supra has a lot more power hidden inside.

    It’s a BMW engine that’s been out for more than 3 years and tuners have been tuning it since day one.
    What is the news here?

  • Ben

    These things pushing 450hp+ would be impressive.

    • Mr. EP9

      It’s definitely possible.

    • Bash

      Same thought, heck I was thinking 470-500 at least.

  • leer1976

    Yep. Not a Supra. This is a BMW with a Toyota designed body on it. Never mind the fact the the Supra was always GT 2+2 not a 2 seat sports car. This is not a Supra.

    • Vassilis

      Would prefer it never existed at all?

      • leer1976

        Would have preferred if Toyota would have taken the chassis from one of the 2 Lexus coupe chassis they currently have. As for the “it has to have a straight six. ” That’s a bunch of bull as well. The only other Japanese Sportscar of the same ilk that had a inline six. The Nissan GTR. Did away with it in favor of their V6 and no one complained and it was an absolute beast.

        • Vassilis

          But those are longer cars and maybe that chassis is also heavier with worse rigidity. Also, the GT-R jumped segment with the R35.

  • Don’tBeSoStupid

    You could quite literally use the “it wasn’t that good until this moment” argument for everything. Not just cars and generations but pretty much every design ever. Supra peaked. Once you set the standard you better be ready to back it up.

  • ErnieB

    The last Supra created a mystique that set a high standard for this to live up to. Most were waiting for this super sports car Supra and instead just got a recycled bmw parts bin sports car with a Toyota designed body- I can understand why most think they sold out. Although a good sports car, it’s not the “halo” car Toyota should have created imo.

    How much is Toyota paying “auto journalists” to push this fake Supra to their readers/viewers?
