A prototype of the new Porsche Boxster has just been spied in the midst of testing at the Nurburgring. While on the surface it looks just like the current Boxster, under the skin it is sporting a brand new engine, namely a new turbocharged unit.
One key reason why the new Boxster and Cayman will adopt four-cylinder engines is to reduce the firm’s CO2 emissions. While Porsche fanatics may be disappointed that four-cylinder engines will be used in the next Cayman and Boxster, Porsche boss Matthias Muller recently said that this smaller engine will be able to deliver up to 395 hp thanks largely to the forced induction.
As the following video highlights, the new turbo’d flat-four certainly sounds different to the current 3.4-litre flat-six naturally-aspirated engine.
This new four-cylinder engine will become just the latest in a long-line of horizontally opposed engines produced by Porsche over the decades and follows on from the four-cylinder engine revealed for the Macan not too long ago.
Interestingly when speaking with Automotive News recently, Muller revealed that the new turbocharged four could eventually be used in other Porsche models, including the 911 depending on how it is received by customers and fans.
