There are few driving experiences as rewarding as a jaunt in a 718 Cayman, a repeat winner of our 10Best Cars award. The Cayman’s pair of turbo fours (base gets a 300-hp 2.0-liter; the S has a 350-hp 2.5-liter) may sound unrefined, but they’re torquey and quick. An engaging six-speed manual is standard; a seven-speed automatic is optional. A GTS model is new for 2018. It uses a 365-hp version of the 2.5-liter engine and comes with a brake-based torque vectoring and adaptive dampers.
