The new four-cylinder engines for the Porsche Cayman and Boxster will not just improve their fuel economy but also allow them to handle and brake more efficiently. Porsche is following the auto industry’s trend in trimming engine size. The offering of new four-cylinder engines also marks a return to its roots. The German sports car maker offered a flat-four engine from 1938 to the mid 1970s.
Porsche also offered inline four-cylinder engines into the 1990s. The new engine being prepared for the Boxster and Cayman will be based on Porsche's classic six-cylinder engines. They will also be part of a modular engine strategy – which entails using common manufacturing lines with the four- and six-cylinder engines sharing many parts, resulting to lesser cost and complexity.
“We will continue with the downsizing strategy and develop a new four-cylinder boxer engine, which will see service in the next-generation Boxster and Cayman,” Porsche chief executive Matthias Muller told Auto Motor und Sport magazine in an interview. “We will not separate ourselves from efforts to reduce carbon dioxide.” Muller suggested that the new four-cylinder boxer engine would provide “up to 395 hp.”
While Porsche has not disclosed which markets would receive the four-cylinder versions of the Cayman and Boxster, Muller has said that the Macan compact SUV would get a four-cylinder engine for the China to comply with legal requirements. Less expensive four-cylinder versions may also be considered for North America.
