Even Porsche has to worry about fuel economy, C02 emissions and weight.
Two popular Porsche sports cars, the six-cylinder Boxster and Cayman, will be getting downsized four-cylinder turbo engines. And, starting next year, they’ll be marketed as the 718 Boxster and 718 Cayman.
The 718 designation signals the move to smaller engines. It is also a historical nod to Porsche’s past success with flat-four engines. In the late 1950s, the 718 was the highest performing Porsche racing engine, developing 142 horsepower and competing at the 24 Hours of Lemans.
Porsche, in a statement, wasn't specific about when the four-cylinder engines will replace or be added to the Boxster and Cayman. But the company does say the new engines will be “equally powerful” as the current generate sixes.
That means the new 718 engines will need to develop at least 265-horsepower, an output that should be easily achievable for Porsche. Subaru, which offers a similarly designed flat four turbo engine in the WRX, has one version that develops 305 horsepower.
It is not clear if the four-cylinder engines will be added to the lineup as entry level engines or if they will replace the six-cylinder motors.
Both Boxster and Cayman have only been available in North America with six-cylinder engines capable of delivering 30 mpg on the highway.
