New Toyota GR Supra vs Porsche 718 Cayman: costs
If power corrupts, having less of it isn’t a bad thing, right? To find out, we're pitting the new four-cylinder Toyota Supra against its main sports car rival from Porsche...
Buying and owning
Costs, equipment, reliability, safety and security
There’s no discount to be had on the Cayman and only a small one on the Supra, so the difference between them is just under £3000 in the Supra’s favour if you’re buying outright. If you don’t care about having an automatic gearbox, going for a manual ’box in the Cayman will save you exactly £2000. Both cars have relatively strong resale values, but they’ll still be worth about 45% less than their original value after three years and 36,000 miles.
Company car drivers will pay the top rate of tax for either car. But because the Cayman has a higher P11D value, it’ll cost you an extra £240 in benefit-in-kind tax over three years (assuming you’re in the 40% tax bracket).
The Cayman is also a little pricier to service, insure and fuel; in our real-world test it averaged 31.3mpg to the Supra’s 37.1mpg. Add up all your likely costs over three years and the Supra will be about £4000 cheaper to run.
When it comes to kit, Porsche is notoriously stingy and would charge you for wheels if it could. As it is, you get 18in alloys as standard, air conditioning and heated seats, and that’s about it. The Supra adds two-zone climate control, keyless entry and power-folding door mirrors.
It has more safety kit, too, including automatic emergency braking and lane-keeping assistance, neither of which are available on the Cayman, plus traffic sign recognition. Neither car has a Euro NCAP safety rating.
Toyota came third out of 31 manufacturers in the 2020 What Car? Reliability Survey, but the Supra was too new to be represented. Porsche, meanwhile, was down in 22nd place, with the Cayman ranking as the least reliable sports car in the survey.
