So at first glance, this doesn’t look that different from the last Porsche Cayman. But the new 718 Cayman—like 911 Carrera, get it?—has some pretty substantial updates, just like its ragtop sister the 718 Boxster. Here’s the lowdown.

The new 718 Cayman, named after a famous Porsche race car from back in the day, goes four-cylinder for the first time ever. The flat-six engines from the previous car have been replaced by two turbocharged flat-fours, one 2.0 liters and one 2.5 liters. (You can only get one engine in a car at a time, sorry.) They’re rated at 300 horsepower and 350 HP, respectively, a bump of 25 horses from the old sixes.
