The Boxster Spyder will use a naturally-aspirated flat-six

Porsche is reportedly developing a new high-performance variant of its 718 Boxster that will share its powertrain with the 911 GT3.

Keeping with tradition, the hottest version of the 718 Boxster will be branded as the Spyder. However, unlike other 718 models to date, the Boxster Spyder won't use a turbocharged four-cylinder; Instead, it'll use the same basic drivetrain found in the 911 GT3.

That means, according to Autocar, the Boxster Spyder will be powered by a naturally-aspirated 4.0L flat-six. That powerplant makes 500 horsepower in the GT3, but it's likely to be detuned for the Boxster. Still, expect a healthy figure somewhere in the 425 horsepower range. A six-speed manual transmission will be fitted as standard, with a seven-speed dual-clutch set to be offered as an available upgrade.

The previous Boxster Spyder, unveiled in 2015, used a 375 horsepower 3.8L flat-six borrowed from the 911 Carrera S.

In order to further boost performance, the 718 Boxster Spyder will be put on a thorough diet that will see removal of things like air conditioning, a radio and sound deadening material. The Spyder will also ditch its conventional cloth roof for a lighter "tent top."

No official launch date has been revealed for the 718 Boxster Spyder, but the high-performance roadster is expected to debut during the first half of 2018. Look for the Spyder to carry a starting price in excess of the $81,900 Porsche charges for the Boxster GTS.
