Porsche boss Matthias Mueller has confirmed long running rumours suggesting future incarnations of the Boxster and Cayman are in line to receive a four-cylinder boxer (or horizontally opposed) engine.
In an interview with Germany's Auto Motor und Sport magazine published last week, 60-year-old Muller said Porsche's road going sports cars would follow the lead of the company's hi-tech 919 Hybrid race car in receiving four-cylinder engines.
But while the 919 Hybrid runs a unique V4 engine with a yet to be official disclosed layout, the unit being readied for the Boxster and Cayman will follow the lead of Porsche's classic six-cylinder by adopting a 180-degree horizontally opposed layout as part of a modular turbocharged boxer engine strategy.
“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,” said Muller. “We will not separate ourselves from efforts to reduce CO2”.
His comments follow those reported exclusively by Drive in January where Mueller strongly hinted four-cylinder engines were on the way for the Boxster and Cayman.
In that interview Mueller ruled out the new four-cylinder engines for use in Porsche's performance icon, the 911.
"There is no idea to have a four-cylinder engine in a 911, he said at the time. "I think we are well prepared with the six-cylinder boxer engine so we will stay with that.”
When queried on the output of the new four-cylinder boxer engine, Muller said it would boast ''up to 400ps (295kW)''. The existing 3.4-litre six-cylinder boxer engine used by the existing Boxster and Cayman develops 243kW and 250kW respectively in new GTS range topping models revealed earlier this month.
