Here's your first full look at the updated Boxster, now with a turbocharged flat-four engine.

After 20 years of six-cylinder, naturally-aspirated power, Porsche is making big changes to the Boxster for 2017. Start with the name: They're not just Boxsters anymore, they're 718 Boxsters. The name is an homage to some little-known four-cylinder racers Porsche built starting in the mid-1950s. The reference is more than skin-deep—for 2017, all Boxsters will be powered by turbocharged flat-four engines.

The base-model Boxster, shown in gray, gets a 2.0-liter flat-four turbo making 300 horsepower and 280 lb.-ft. of torque, an increase of 35 horses and 74 lb.-ft over the outgoing Boxster. The Boxster S, shown here in orange, makes 350 horsepower and 309 lb.-ft, increases of 35 horsepower and 43 lb.-ft., respectively.

The 718 Boxster and Boxster S will arrive in U.S. dealerships in late June. The base model starts at $56,000, while the 718 Boxster S starts at $68,400.
