PORSCHE has unveiled the new 718 Cayman, the latest and fourth generation of the mid-engined, two-seater sports coupe with a new flat-four turbocharged Boxer engine delivering upwards of 300bhp.

Since its debut in 2005 the Cayman has earned a reputation as a driver's car among owners and fans alike.

Like the Porsche 718 Boxster, the new 718 Cayman models continue the tradition of the Porsche 718 mid-engined sports cars that won numerous races in the 1950s and 1960s, powered by four-cylinder Boxer engines.

The same new four-cylinder engines with turbocharging that first debuted in the 718 Boxster are shared with the 718 Cayman. As a result both, coupe and roadster Porsche models offer identical engine outputs for the first time.

The 718 Cayman is powered by a 2.0-litre engine while the 718 Cayman S features a 350bhp 2.5-litre engine.

This represents 25bhp more power compared to the previous models, with claimed fuel economy also increasing to 34.9 - 40.9 mpg combined.

Performance from the newcomers is impressive. The 718 Cayman S completes the 0-62mph sprint in 4.2 seconds.

The top speed of the 718 Cayman is 170 mph and the 718 Cayman S can reach a speed of 177 mph.

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