Spotted testing at the Nürburgring this week, the car will use a detuned version of the new 911 GT3’s 4.0-litre flat-six, although power is expected to increase over the previous generation's 380bhp, with 400bhp-plus expected.
“Natural aspiration is one of our main USPs,” said Andreas Preuninger, head of GT car development at Porsche. “At Motorsport, we think we can achieve throttle response and immediacy a little bit better with an atmospheric high-revving engine than any kind of turbo.”
Preuninger also confirmed that there are no plans to create any four-cylinder GT cars.
Autocar has speculated that the next Cayman GT4 will be powerful enough to wear the RS badge, which is reserved for Porsche’s most hardcore models, and Preuninger dropped a broad hint that it will come with both manual and PDK gearbox options.
“The aim is to always have the choice,” he said. “Now we’ve started with that strategy with the GT3, let’s hope that it pays off.”
Preuninger also said Porsche will crack down on speculators who buy GT cars to flip for a profit rather than to drive. “If you do it, you won’t get the next car,” he said.
The previous Cayman GT4 was priced from £64,451 — around £10,000 more than the Cayman GTS. If a similar pricing strategy is employed this time around, the new Cayman GT4 will cost just shy of £70,000.
