Porsche is developing a new four-cylinder engine set to power entry-level model

High-ranking officials at Porsche's Weissach research and development center in Germany have confirmed that engineering work is progressing on a four-cylinder horizontally opposed gasoline engine, details of which were first revealed by Autoweek earlier this year. The new boxer unit--which is earmarked to power a new mid-engine, entry-level model that insiders describe as a spiritual successor to the iconic 550 Spyder--looks set to become an integral part of Porsche's future model plans.

Those obsessed with torque bemoaned Mercedes’ high-revving 6.2-litre V8 when it was launched in 2005, but just as the world has come to accept the naturally aspirated engine, the company has now unveiled a new twin-turbo 5.5-litre V8. Up to 563bhp – which is the same as the SLS AMG – and 663lb ft, which is much more than the 479lb ft the modern-day Gullwing supercar manages. The engine is an all-new 5.5-litre V8 (5461cc to be exact) with direct-injection technology, an aluminium crankcase and two turbochargers.
