Porsche 718 Cayman – The Middle Kingdom

Porsche’s latest mid-engine Coupe raises the bar in most respects.

When Porsche launched the original Cayman in 2005, they emphatically stated that it was not a Boxster Coupe. With more powerful engines set up for sharper response and higher revving capability, and a much stiffer structure than its roadster sibling, the Cayman was a more driver-focused car designed to bridge the gap between Boxster and Carrera.

Unfortunately, this message was not clear to the buying public who asked why, contrary to the accepted norm, this Coupe was more expensive than what was perceived to be its Roadster sister.

Accepting its inherent mid-engine balance and the Porsche engineer’s ability to create near perfect handling, the fundamental cornerstone of the Cayman’s dynamic excellence was its exceptional structural stiffness.

This meant the Cayman quickly gained favour with hard-core Porsche enthusiasts and track day addicts.”

“Over time however, succeeding generations of Boxster became better and better, with the recent 981 generation approaching the dynamic prowess of its fixed-head stable-mate,” he recalled. “The 718 Boxster has a 19,000Nm/degree torsional stiffness number that significantly closes the handling gap when you drive the two cars back-to-back.”

The body-in-white weighs about 5.0kg more, but the extra reinforcement and new rear suspension design helps the 718 Cayman set the sportscar benchmark for structural stiffness, with an impressive 40,100Nm/degree. This exceeds the big numbers of some super sports cars with carbon-fibre centre tubs!

With the further dynamic improvements built into the 718 Boxster, Porsche now considers the Boxster and Cayman as having morphed from two separate model lines into one.

Thus, Porsche presents the 718 Boxster and Cayman in the same conventional way the Cabriolet and Coupe do in the Carrera range, with both open and closed variants now sharing identical drivetrain and engine outputs.

There is no question that the 350hp 2.5 litre single VTG technology turbocharged flat-four that powers the 718 models is punchier and more effective against the stopwatch than the 3.4 litre, naturally-aspirated six that went before.
