Porsche recently introduced two high-performance version s of existing models in its product line, the GT4 version of the 718 Cayman and a Spyder variant of the 718 Boxster. Both are powered by a new flat-6 engine developed for them.
Although it might not have been just for them. Porsche has just confirmed it had bigger plans for this new unit than to have it service two niche products. We can expect to see the 6-cylinder mill migrate to other models across the company’s product range.
The new 4.0 engine in question has virtually nothing in common with the 3.0L 6-cylinder unit that powers the 911, according to Andreas Preuninger, head of Porsche’s GT division. The executive confided to the Car & Throttle website that his team developed several components for the new engine, including pistons, housing, crankshaft and cylinder heads, among other parts. The company took this costly step because the 718 cannot accommodate the 911’S engine. It was also decided that a 4cylinder turbo engine would simply not be credible in the eyes of many potential buyers.
We believe in normally-aspirated engines, especially for cars in that niche -- puristic cars. To be frank with you, we can use this engine in the future on other models maybe as well.
