Cayman GT4’s success inspires Porsche to look at giving the new Boxster Spyder the full GT treatment
13 April 2015

Porsche is considering building a GT4 version of the new Boxster Spyder.

Spurred by demand for the Cayman GT4 exceeding all its internal predictions, a senior source at the company said, “We are looking at it right now. Much of the engineering has already been done for the Cayman, so we think this might be a good direction for us.”

A GT4 Boxster Spyder would most likely adopt the hardware seen in its Cayman equivalent. The Spyder already shares that car’s 3.8-litre engine but lacks its GT3-derived fully adjustable front suspension and bespoke rear suspension. It would also gain full GT3-specification brakes in place of the 911 discs on the Spyder, plus the Cayman GT4’s aerodynamic package.

Porsche would need to watch its pricing because, at £60,459, the Spyder is already close to the £64,451 asked for the Cayman GT4, higher in its model hierarchy.

In the meantime, Grant Larson, the chief designer of the Boxster Spyder, has revealed more details on how the Spyder shed 30kg relative to the Boxster GTS, despite its bigger 3.8-litre engine.

Savings included 11kg by fitting sports seats, the same again from the car’s largely manual roof arrangement and 9kg from deleting air-con. In total, 55kg was saved, from which items including bigger brakes (12kg) and wheels (2kg) can be deducted.

Meanwhile, Porsche says the success of the GT4 makes an RS version more likely.
