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.
With the new Cayman, Porsche is once again expected to set new standards in its class when it comes to driving performance. Compared to the previous model, the new version weighs less, shows a longer wheelbase, and has a new all-round chassis. Developed from scratch, this two-seater is the third sports car model series from the brand to have a cutting-edge lightweight body design.
The first two were the 911 Carrera and the Boxster. Design-wise, the lines are more prominent and reveal new proportions. Indeed, the new Cayman is more unique than ever. The main reason why the proportions were somewhat changed was to allow it to put focus on its quality as a sport coupé.
Having a wheelbase that is longer by 60 mm plus a broader track width, this new model has a more extended and lower look especially when you consider that the height is lower by 10 mm. For the Cayman S, the height is slower by 11 mm. This two-seat sports car though remains to be compact given that the overall length is longer by 33 mm. As mentioned, the new Cayman is lighter.
Depending on the equipment and the specific model, the new version can be lighter by as much as 30 kg. In addition, when compared to the previous model, fuel consumption for every 100 km is 15% less.
This is true despite the fact that the new version has better driving performance and the engine is more powerful. Further, the body is stiffer by 40%, which enhances even more the athleticism of the driving artist in bends.
Porsche disclosed as well that the Cayman will be upgraded and fitted with a number of optional features. This sport coupé will come with Adaptive Cruise Control (ACC), a first for this model.
This system is the one that manages the vehicle speed and the model’s distance in relation to the car in front of it. Included as well is the newly developed Burmester sound system. New as well is the Entry & Drive keyless system, which while optional, can be factory installed.
