Porsche has introduced a mixed aluminium-steel body-in-white construction to its latest generation Cayman sports car, reducing the structure's weight by 47kg.
The new vehicle benefits from the use of die-cast aluminium, sheet aluminium, magnesium and high-strength steels and now weighs 1,320kg, compared to the previous generation's 1,330kg, helping to improve performance and efficiency.
Some of the weight reduction has been offset by a larger glass surface area and larger wheels.
Porsche said: “The body of the new Cayman is an entirely new development based on the body-in-white of the Boxster. Around 44% of the new Cayman body-in-white consists of aluminium, including the front body, floor and rear body, the doors and the front and rear boot-lids. At the same time, the car's static torsional rigidity has been boosted by 40 per cent.”
The Cayman uses either a 202kW 2.7-litre flat-six cylinder gasoline engine or a 239kW 3.4-litre engine which produce 192g/km and 206g/km CO2 respectively when mated to the six-speed manual transmission. The previous vehicle emitted 222g/km and 254g/km.
