Our 2026 Porsche 718 Cayman GTS 4.0 Rating
FORPORSCHE RATING: 10/10
Pros
4.0L naturally aspirated flat-six transforms the character of the entire car; 394 hp with a spine-tingling engine note; GTS suspension tuning; the Cayman in its most complete form.
Cons
Most expensive non-RS 718 Cayman; flat-six increases fuel consumption vs. turbo 4-cylinder variants.
Verdict
The definitive Cayman. The flat-six is transformative and makes the GTS 4.0 feel like a completely different car to any four-cylinder 718. If the budget stretches this far, this is the one to buy.
