2019 Porsche 718 Boxster Spyder Spied Testing a Flat-Six Engine

The Porsche 718 Spyder lineup is adding a naturally aspirated Boxster model.

All three 718 Spyder offerings currently feature turbocharged four-cylinder engines, but this year, we will see the introduction of the 718 Boxster Spyder with a naturally aspirated, flat-six engine. The German automaker has already confirmed the Spyder and the Cayman GT4 will stay naturally aspirated, but output will be closer to 400 horsepower than 500. Look for a six-speed manual transmission to be paired with the engine, although there are rumors a PDK will be offered as an option.

Spied testing near the Arctic Circle, this particular prototype is still wearing the Sport Design package’s front apron that comes standard on the GTS, but the production model will likely have a different bumper. The rear appears to be testing a new diffuser for the updated exhaust layout.

The 4.0-liter flat-six engine is expected to be a detuned version of the 911 GT3’s powerplant, while a proper diet will keep the Boxster Spyder as lightweight as possible.
