Don’t get us wrong, the car is great but how would you feel if you supported the launch of a new model by being one of the first owners, only to find that said model received significant upgrades only one year later?

Surely that should feel like a slap in the face for some 2020 Supra owners, given that Toyota has given the 2021 model a hefty power upgrade. On paper, the 3.0-liter turbocharged straight-six engine now makes 382 HP and 368 lb-ft (498 Nm) of torque.

That’s a 47 HP increase over the 2020 Supra, which is officially rated at 335 HP and 365 lb-ft (494 Nm) of torque. But is the power difference between the two models really that big? Car&Driver wanted to find out so they took their long-term 2020 Supra and the new 2021 Supra to Livernois Motorsports & Engineering in Dearborn Heights, Michigan and let them duke it out on the dyno.

As it turns out, the 2020 Supra produces more power than advertised, with the measurements reading an impressive 346 horsepower at the wheels (WHP). Taking driveline losses into consideration, this means the 2020 model delivers way more than the official 335 HP. Unfortunately, Car&Driver does not reveal the exact power output at the crank.

As for the 2021 model, the dyno test reveals it delivers 388 HP at the crank – 6 HP more than the official rating. Rather curiously, the video does not reveal the 2021 Supra’s WHP figure so we don’t really have an accurate comparison of the actual power output at the crank of each model year Supra. What the dyno test does show is that the power difference is significantly smaller than 47 HP and that should be good news for folks with 2020 Supras in their garages.
