Toyota Supra: More Power Than Advertised?

Not everyone was enthusiastic about Toyota’s decision to co-develop its Supra with BMW. As an icon of the brand, some complained that Bavarian involvement sullied what should have a been a purely Japanese automobile. We wouldn’t go that far (though certain telltale signs of BMW’s hand come off as slightly off-putting). Still, an interior that borrows heavily from the Z4 is hardly a major issue, especially since everyone knew they’d be platform partners going into this.

As well, partnerships can bring advantages. In addition to actually resulting in the car being built, Toyota’s relationship with the Germans means an engine that miraculously makes more power the second you place it on a dynamometer.

Following some on-the-pavement testing of the Toyota Supra, Car and Driver noted that the coupe’s BMW-sourced twin-scroll turbo 3.0-liter inline-six was outperforming vehicles that should have been a little out of its league. Are the A90 Supra’s power specs understated?

Possibly. This is a powerplant from BMW, after all.

Scheduling some time with an all-wheel-drive dyno, the outlet suggests the Supra’s stated 335 horsepower and 365 lb-ft of torque are a misnomer. The real numbers should be closer to 339 horsepower and 427 lb-ft of torque at the wheels.

From Car and Driver:

For our test, we headed to Livernois Motorsports and Engineering in Dearborn Heights, Michigan. We strapped the Supra to the Dynojet all-wheel-drive dynamometer, as the car’s stability systems only play nice when all four wheels are spinning. For this observation, we ran the test in the eight-speed automatic transmission’s fifth-gear ratio of 1.32:1 to achieve a full sweep of the tachometer. We experimented with the 1.00:1 ratio of sixth gear but were unable to reach the engine’s redline. The power output in sixth gear, however, matched our results of those in the higher gear.

All dyno-derived figures, of course, come with a complimentary grain of salt. C&D‘s findings aren’t likely to appease those who bemoan the fact that Toyota’s pride and joy utilizes a German motor, though it could help silence complaints that the new car barely makes more power than a 2JZ-equipped Mk4. We’d recommend a side-by-side showdown to settle things once and for all.

Sadly, there probably aren’t enough unmodified examples of the A80 left to make that a reality.

Clients included several of the world’s largest automakers, global tire brands, and aftermarket part suppliers. Dissatisfied with the corporate world and resentful of having to wear suits everyday, he pivoted to writing about cars. Since then, that man has become an ardent supporter of the right-to-repair movement, been interviewed on the auto industry by national radio broadcasts, driven more rental cars than anyone ever should, participated in amateur rallying events, and received the requisite minimum training as sanctioned by the SCCA. Handy with a wrench, Matt grew up surrounded by Detroit auto workers and managed to get a pizza delivery job before he was legally eligible. He later found himself driving box trucks through Manhattan, guaranteeing future sympathy for actual truckers. He continues to conduct research pertaining to the automotive sector as an independent contractor and has since moved back to his native Michigan, closer to where the cars are born. A contrarian, Matt claims to prefer understeer — stating that front and all-wheel drive vehicles cater best to his driving style.

    Meh, this is nothing new. The Gen I Ford Probe advertised "crank" HP and torque were wheel HP and torque.

    Also uglier than people had expected after having seen the concept 4-5 years ago.
