As Green Car Guide reaches its tenth anniversary of seeking out the most economical cars in all categories, we’ve been rewarded with a Porsche 718 Cayman that can manage over 40mpg.

Now known as the 718 Cayman, the fourth generation of the mid-engined, two-seater sports coupe has new flat-four turbocharged ‘boxer’ engines delivering upwards of 300 hp.

The same new four-cylinder ‘boxer’ engines with turbocharging that first debuted in the 718 Boxster are shared with the 718 Cayman. As a result, coupé and roadster Porsche models offer identical engine outputs for the first time. The 718 Cayman derivative is powered by a 300 hp (220 kW) 2.0-litre engine. The 718 Cayman S features a 350 hp (257 kW) 2.5-litre engine. This represents 25 hp more power compared to the prior models, with NEDC fuel economy also increasing to 34.9 – 40.9 mpg combined.

The 2.0-litre engine of the 718 Cayman produces up to 380 Nm (plus 90 Nm) of torque, generated between 1,950 – 4,500 rpm. The 2.5-litre engine of the 718 Cayman S features a turbocharger with variable turbine geometry (VTG), technology previously only used in the 911 Turbo.

The 718 Cayman with PDK and optional Sport Chrono Package has a 0-62mph time of 4.7 seconds (4.2 seconds for the 718 Cayman S). The top speed of the 718 Cayman is 170 mph, and the 718 Cayman S can reach a speed of 177 mph.

The comprehensively retuned chassis of the 718 Cayman has increased dynamic responsiveness and cornering grip; springs and anti-roll bars have been designed to be firmer and the tuning of the shock absorbers has been revised. The steering, which has been configured to be ten per cent more direct, enhances agility and consequently increases driving pleasure further still. The rear wheels, which are half an inch wider, in combination with the re-developed tyres result in an increased lateral force potential and hence greater cornering grip.

Driving dynamics options such as the Sport Chrono Package and the Porsche Torque Vectoring (PTV) electronically-controlled rear limited slip differential allow the sporting character of the 718 Cayman to be further custom-tailored to suit individual preferences. Another available option is Porsche Active Suspension Management (PASM) with -10 mm lower ride height. Additionally, in the S model, PASM sport suspension combined with a – 20 mm lower ride height is offered for the first time.

The Sport Chrono Package can be adjusted via the mode switch on the steering wheel. Supplementing the previous settings of ‘Normal’, ‘Sport’ and ‘Sport Plus’ is the ‘Individual’ programme, which is able to call up previously programmed individual settings for various systems.

The new 718 Cayman models are available to order from Porsche Centres in the UK and Ireland. For the first time, the coupé is priced below the roadster – in a similar way to the 911 models. First deliveries begin in the autumn.

The 718 Cayman is priced from £39,878, and the 718 Cayman S costs from £48,834.
