The two new Cayman engines, smaller displacement versions of those in the 911, come just three years into the car’s product cycle, demonstrating the company’s resolve to reduce its environmental footprint.
Fuel consumption on the base model’s 2.9-litre six is down by up to 11 per cent depending on the transmission choice, while consumption on the S models is down by up to 16 per cent.
The double-clutch, automated-manual version of the base Cayman uses just 8.9 litres per 100km (9.2L/100km in manual form), while the Cayman S uses 9.2L/100km (9.6L/100km in manual).
The fuel efficiency improvements to the base Cayman engine come despite a larger displacement engine (up from a 2.7-litre unit on the previous model) and an 8 per cent power increase.
On the S model, displacement has remained the same, but power is up by 8 per cent.
