A prototype version of the new Porsche Panamera has been spotted testing in winter conditions, as the German firm prepares to launch the third-generation model for the end of 2023.
The model, which was not wearing the Porsche badge, was pictured with a solid black exterior paint. Its front-end design is similar to the current Panamera, while the rear features new lights and an updated spoiler.
The new Mk3 model, which goes by the internal working name 972, looks set to continue the German company’s long tradition for small, evolutionary changes between generations, with an exterior design that subtly progresses the look of the six-year-old second-generation Porsche Panamera. Underneath the steel and aluminium bodywork, though, Porsche is lining up more significant modifications for its BMW 8 Series Gran Coupé and Mercedes-Benz CLS competitor.
With the two-year-old Porsche Taycan saloon leading the firm's electric vehicle push, the Panamera is due to receive a revised range of petrol powertrains, all with heavily reworked exhaust systems and tweaked software aimed at meeting the upcoming Euro 7 emission regulations.
Along with updated versions of today’s twin-turbocharged 2.9-litre V6 and 4.0-litre V8 engines, featuring 48V mild-hybrid properties, the new Panamera looks set to adopt a heavily revised plug-in hybrid powertrain that is also planned for the upcoming Mk4 Cayenne SUV.
Details remain scarce, but Autocar has been told that successor models to the 4 E-Hybrid, 4S E-Hybrid and range-topping Turbo S E-Hybrid will receive both revised petrol engines and electric motors in combination with a larger-capacity battery pack and newly developed software that will enable faster charging rates.
Although nothing is official yet, the overall power output of each Panamera variant is said to have been increased.
In combination with revised driving mode functions, the reworked plug-in hybrid system is expected to offer “significantly more” than the 31 electric-only miles of the current E-Hybrid models.
