Porsche Boxster GTS

According to a German media report, Porsche has confirmed plans to offer four-cylinder engines in its next-generation Boxster and Cayman small sports cars. No timetable was attached to the plan.

Flat fours are nothing new for Porsche as they were used in all pre-911 356s and 550s, as well as the 911-based 912 and the 914. The new four-cylinder is said to be a modular adaptation of the brand's current horizontally-opposed six-cylinder, allowing the use of the same manufacturing and assembly facilities as well as many common parts.

The current six displaces 3.4 litres so, assuming use of the same bore and stroke dimensions, the four-cylinder would displace 2.3 litres (2667 cc). Nearer term, Porsche has announced the addition of GTS models to both the Boxster and Cayman lines. It's the first time the GTS label has been applied to a mid-engine Porsche since the 904 of the mid-1960s.

In both cases, the GTS's 3.4-liter flat six delivers an additional 15 horsepower compared to their "S" model counterparts. The Boxster GTS is rated at 330 hp and the Cayman GTS at 340 hp. Torque has been increased by 7 lb.-ft in each case, to 273 lb.-ft in the Boxster GTS and 280 lb-ft in the Cayman GTS. flat six.

Both models also get distinctive trim identification and standard equipment upgrades.
