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.

Originally, AMG's new front-engined sports car was tipped to revive the iconic SLC name first used by the SL coupe back in 1971.
