Porsche: four cylinder powerplant in the works

Porsche is working on a new four-cylinder petrol engine that would power its new baby roadster, the Boxster, the Cayman and potentially even the 911.

Outgoing head of R&D Wolfgang Durheimer said at the Detroit show: “We have a four-cylinder boxer engine under development.” He admitted that the unit can be applied to the Boxster and Cayman.

There was some indication that the sub-Boxster Porsche would borrow bits from a sister car built by Volkswagen and Audi, and while that route would certainly cut down on development costs for all three cars, Porsche seems to be bent on powering its version with a beating heart designed and developed in house. Sources said that the new flat four motor is 2.5 litres and can churn out around 360bhp in turbocharged form.

Durheimer said that for the time being, Porsche plans to keep to the flat-six for its bread-and-butter sports machine, the 911. However, there's no telling how long more this would hold.

I have been a car fanatic since 1989, when my father was changing our family car then to a Toyota Corolla 1.6 GL fitted with a Twin Cam 16 valve engine that was carburetor-fed, a big deal back in those days. The automobile technology and industry fascinates me and I hope to broadcast these interesting developments to everyone out there through this blog.

Just license one from a certain Fuji Heavy Industries and give it twin turbo + Doppelkupplungsgetriebe

^Agreed. Subaru's been at this game (turbo boxer 4s) for so long, and they make some awesome cars. Loving the Top Gear reference, btw. :)

This would be a great innovation to the cars of Porsche. It may look like the four-cylinder is a standard type of engine but Porsche was able to make it more powerful that it can boost more than 300+ horsepower in a turbocharged form. I'm kinda anxious if the new engine would work with the current porsche boxster coolant, oil and other things. Anyway, looking forward to see the actual performance of this new four-cylinder petrol engine.
