Porsche is planning to introduce a flat-four engine on the Boxster and Cayman models, later on this year.
Downsizing is everything these days and while the Boxster has become famous with its flat-six engine, smaller than the one used on the more powerful 911, the model will now get an even smaller engine. In fact the new unit will be so small that two cylinders will be left on the assembly line. According to the guys at flat6news.com, the Porsche Boxster will get a four-cylinder engine under its hood, which will be unveiled later on this year. The same unit will also be adopted by the new Cayman generation.
Our source is saying that the new flat-four engine will come as a 2.5 liter unit, with DFI (Direct Fuel Injection), VarioCam Plus and a single turbocharger. The unit will produce a total output of more than 350 BHP (261 kW) and it will have a peak torque of 487 Nm (360 lb-ft). The red zone will be at 7,500 rpm and the unit will be mated to an updated PDK transmission. The Porsche Boxster and Cayman equipped with a flat-four engine will be officially presented to the public in September, during the 2013 Frankfurt Motor Show.
