Porsche is now pursuing a plan that could see pure-electric Boxster and Cayman variants using the company’s new PPE architecture offered alongside updated versions of today’s models featuring hybrid and plug-in hybrid drivetrains.
The plan would mirror the move taken by Porsche with the next-generation Macan, which will continue to be produced on its existing MLB platform with new hybrid drivetrains while offering the choice of a pure-electric variant based on the PPE architecture.
Speaking about Porsche’s plan for the second-generation Macan, Blume said: “For at least two to three years we will have both. At that point, we can decide whether to upgrade the combustion engines to the new Euro 7 standard or go full electric. The pace that countries are changing is different – China wants electric now, Russia is in less of a hurry, for instance.”
The new mild-hybrid and plug-in hybrid drivetrains intended for the 718 models are developments of those already engineered for the larger 911, according to sources. The electrification measures are among changes designed to allow Porsche’s existing combustion engines to meet the upcoming EU7 emissions standards.
However, while the hybrid systems scheduled to appear on the facelifted version of the eighth-generation 911 early next decade are based around Porsche’s horizontally opposed six-cylinder petrol engine, those being earmarked for the new 718 Boxster and Cayman are set to use the smaller-capacity flat four engine introduced by Porsche in 2016.
Both units feature a 48V electrical system and disc-shaped electric motor integrated into a modified version of the existing Boxster and Cayman’s seven-speed dual-clutch automatic gearbox.
The mild-hybrid system has been conceived to provide an electric boost to the petrol engine for added performance potential and increased efficiency, albeit without the ability to provide an electric-only driving mode. The plug-in hybrid also provides electric boosting but has been built around a battery of sufficient capacity to offer extended pure-electric running.
