Now that the  Porsche  718 Boxster and Cayman GTS models have been introduced, we can look forward to the new 718  Boxster Spyder  and Cayman GT4.

Spy photographers have already caught the new Porsche 718  Cayman GT4  testing and reports suggest it will use a detuned version of the 911 GT3’s 4.0-liter naturally aspirated flat-six engineinstead of a turbocharged flat-four mill. We can expect to see the same powerplant make its way to the new Boxster Spyder, offering around 425 horsepower. The previous Boxster Spyder featured a 3.8-liter flat-six engine borrowed from the 911 Carrera, good for 375 hp. But considering the new GTS models have 365 hp, expect to see a more modest increase in performance for the Spyder and  Cayman GT4  to widen the gap.

As a driver-focused model, expect to see the new Boxster Spyder offered with a six-speed manual transmission as standard, while an optional seven-speed PDK dual clutch will be available. The sports car will also go on a diet with the automaker tossing out considerable cabin insulation, the radio, and even air conditioning. The electric folding soft top will also not be used, replaced by a manually-removed top.

The next 718 Boxster Spyder should make its debut sometime next year.
