Yes, there will be another Cayman GT4 with a six-cylinder naturally aspirated engine and manual gearbox.

The success of the original GT4 has been well noted by Porsche management, providing a great "halo" model for the range.

The Cayman GT4 was heavily oversubscribed and sold out much quicker than expected, as demonstrated by the secondary market levels.

The flat-six engine is a defining characteristic that cannot be replicated by a four-cylinder turbo. Indeed, the five-cylinder engine in the Audi TT RS has considerably more character than the new four-cylinder 718 engine. If you drive a four-cylinder 718 (maybe try one as a courtesy car) you will appreciate what a difference it makes to the character.

Porsche is understandably rather shy to talk openly about future models, as they prefer customers to focus on buying cars from the existing range.

The traditional approach of Porsche's sales strategy is to offer the more exciting models later in the product cycle of a given range.

There will be another Cayman GT4, but we need to be a little patient...

...and after the next generation GT3 and GT3 RS, there may even be room in the product line for a GT4 RS!
