You're looking at the next Porsche 718 Cayman GT4, spied on test during endurance testing at the Nurburgring in Germany.

It's set to provide a new way for purists to enjoy six-cylinder power in their 718, Porsche's junior sports car range that recently switched from six-pot boxer engines to flat fours - with a resulting loss in acoustic frenzy.

Porsche 718 Cayman GT4: six-cylinder power confirmed

Andreas Preuninger, head of the Porsche GT models, has gone on record as saying that the GT4 will be naturally aspirated, pointing to a detuned version of the 4.0-litre flat-six found in the new 911 GT3.

As the outgoing Cayman GT4 boasted 385bhp, that suggests the new one will likely deliver nearer 400bhp.

Brawny engine and drivetrain implants will take care of the firepower, but the chassis and bodywork will be given a significant makeover too; expect lightweighting and exotic materials galore to make the coupe perform, handle, corner and brake better than ever.

When can I buy the new 718 Cayman GT4?

Porsche is the past master of stoking interest in its model ranges as they gently age. With facelifted 718s already doing the rounds of testing, we'd suggest the new GT4 is likely to be a 2018 model year entry.

This car pictured in CAR magazine's spy photos is a chassis test mule, according to our spies at the Nordschleife, who report that the wheelarches are stuffed with foam packing to make the GT4 prototype look much wider.

'And the exhaust is also not really well fitted - another indication that there is a new engine in the car,' says our man with the long lens.

Other telltale giveaways that this is a GT-series Porsche are the delicate fixed rear wing, the lightweight alloy wheels wrapped in liquorice-thin, track-focused tyres, the lower ride height and a serious-looking rear diffuser to channel air under the car and create meaningful downforce during high-speed track work.

Yep, it looks like Porsche might have another mouth-watering driver's car on its hands...
