A U.S. publication has gotten their hands on a new Toyota GR Supra and hooked it up to a dyno. The car produced more power than officially stated.
BMW, which have been reported before on other occasions to under quote its power figures, apparently did so with the engine in the Supra too.
According to Toyota, the car is supposed to output 335bhp and 494Nm of torque but the dyno threw up figures of 339bhp and 578Nm of torque instead. Car&Driver did the run with the car running in fifth gear and since these numbers were wheel horsepower outputs, it meant that at the crank, the 3.0-litre turbo straight-six could have actually been pushing around an impressive 370-380bhp.
On a side note, the magazine noted that the peak torque figure achieved may be a little inflated as the car’s torque converter probably isn’t fully locked until higher up in the rev range.
This also explained how the magazine managed to clock the car doing its 0-96km/h timing in a scant 3.8 seconds while its official 0-100km/h figure was 4.3 seconds.
