The upcoming Panamera facelift is expected to be unveiled before the end of the year.
Porsche recently celebrated the tenth anniversary of the Panamera, and while rumors have suggested the lineup will be expanded with new coupe and convertible versions, the regular version is also about to get a facelift. According to Autocar, the Mercedes AMG GT 4-door rival will be unveiled before the end of the year and will receive subtle exterior changes, including an altered tail-light design with an LED strip linking both units. The changes will bring the design in line with newer Porsche models like the updated Cayenne and 992-generation 911. The changes won't only be cosmetic, however.
Autocar claims that Porsche is planning to introduce its first mild-hybrid powertrains for the Panamera. The S and 4S models will use the same 2.9-liter twin-turbo V6 as before, but both models are likely to adopt the 48-volt electrical architecture that was recently added to the 2020 Audi S6 and S7.
This will allow the fitment of a mild-hybrid system, using the integrated motor generator to harvest electrical power to provide an efficiency boost and allow the start-stop system to activate sooner. Audi's electric compressor system is also expected to be included to fill in the gaps in torque delivery while the turbochargers spool up. Inside, the Panamera's interior is already as up to date as other new Porsche models, so we'll likely see more technology upgrades rather than design changes such as more advanced infotainment and assist features.
Expect the current Panamera's model range to carry over, but we could see some performance improvements. Currently, the entry-level variant has a turbocharged 2.9-liter V6 that produces 325 hp and 332 lb-ft of torque, while the Panamera S has a twin-turbo 2.9-liter V6 with 434 hp and 406 lb-ft of torque. Further up the range, the GTS features a twin-turbo 4.0-liter V8 developing 454 hp and 457 lb-ft of torque and the range-topping Panamera Turbo increases the output to 542 hp and 568 lb-ft of torque.
As for plug-in hybrid variants, the Panamera E-Hybrid has a twin-turbo 2.9-liter V6 and an electric motor producing a combined 456 hp and 516 lb-ft of torque, while the more powerful Panamera Turbo S E-Hybrid uses a twin-turbo 4.0-liter V8 engine and an electric motor to produce 671 hp and 627 lb-ft of torque.
