Toyota Supra vs BMW M2 vs Porsche Cayman

The Toyota Supra has been in the news recently with reports like this one on MotorBiscuit alleging that a $55,000 model was sold for almost twice that price. How does it compare against the BMW M2 and the Porsche Cayman, both of which are about $10,000 more expensive than the Toyota Supra? AMCI Testing is a good agency to ask this question since it’s been in the business of evaluating cars and trucks for over 35 years. AMCI tests over 150 vehicles at its facilities in Southern California. In August 2019, AMCI Testing published the results of their closed-course laps testing on the Supra, M2, and Cayman.

The detailed specifications of the three cars are on this AMCI Testing page.

Test Specifications

All three cars were new at the start of testing. They were broken in by driving for 2000 miles, according to each car’s specifications, before track testing commenced. The cars had new, scrubbed, original equipment tires and electronic stability controls were turned off for the test.

AMCI Testing’s expert drivers drove the cars around their Streets of Willow Springs test tracks. They drove a total of 175 laps to figure out the vehicle configurations for the best performance for each vehicle. Each car was driven by multiple drivers to calculate a meaningful per lap average time from eight laps.

Test Results

The Toyota Supra turned in a faster average lap time than its pricier competitors: it clocked in at 1 min 9.75 secs while the M2 took 1 min 10.25 secs and the Cayman’s time was 1 min 10.97 secs. Not only did it go faster, but the Supra stopped a lot better as well: it’s 80-0 mph braking distance was 182.2′, the Cayman needed 191′ and the M2, 199.6′.

And, the Supra also did well in generating the highest G-force for turning a 180˚corner: 1.171 for the Supra vs 1.105 for the Cayman and 1.100 for the M2. For those looking for super sports car performance, the Toyota Supra provides more of it at a lower price than its closest competitors.
