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

Expect a new six-speed manual transmission, like that found in the latest GT3. Yep, Porsche continues to offer the purists' solution - and long may that continue...

The new Porsche 718 Cayman GT4

As the outgoing Cayman GT4 boasted 385bhp, that suggests the new one will likely deliver the full 400bhp, if not a little more.

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.

We drove a Cayman GT4 Clubsport racer to give you some idea of what to expect. Rear our review here.

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 2019 model year entry. Despite this car looking close to production, word is it won't be shown in 2018.

The outgoing GT4 wasn't a limited series production car and sales figures show that it actually out-sold the 2.7 in the last-generation Cayman. An extraordinary - and heartening - fact. More than 500 were registered in the UK.

Spy photos from Germany: the 2018 Porsche 718 Cayman GT4

There's some pretty serious aero on this latest prototype: check out the full-width rear wing and diffuser on our new spy photos (above). Twin exhuasts complete the look.

Other telltale giveaways that this is a GT-series Porsche are the lightweight alloy wheels wrapped in liquorice-thin, track-focused tyres, the lower ride height and Porsche's composite brake discs the size of brass band cymbals.

This car has a rollcage installed, but we expect that's to protect occupants when it's testing on the Nurburgring circuit. Note also the GT2 RS-style front splitter - designed to be so strong, that a man can stand on it without deforming. All the better to keep a constant downforce even at high speeds.

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