As good as Porsche's 718 Boxster and Cayman are, they possess a significant Achilles heel: the engine. While the Subaru-like, turbocharged, 2.5-liter boxer fours provided superior performance and alleged fuel economy, they lacked the atmospheric noise and character of the flat-sixes that graced Boxsters and Caymans (Caymen?) of years past.

According to a report by Autocar, however, Porsche will be giving the Boxster its flat-six mojo back in the form of the upcoming 718 Boxster Spyder. It won't be using just any old flat-six either, as Porsche plans to give the new Spyder the 4.0-liter, naturally-aspirated screamer straight out of the firm's 911 GT3.

The GT3 engine. In a Boxster. Where the hell do we sign?
