Porsche will release a midlife update for the Panamera saloon and Sport Turismo estate in early 2020, as evidenced by lightly camouflaged prototypes spotted testing in the open.

The earliest timeframe for the Panamera is likely towards the end of 2019, with the Mercedes-AMG GT 4-Door rivalling car sporting subtle revisions to its styling reflecting Porsche’s latest design ethos.

Perhaps the biggest update to the new 2020 Panamera will be the addition of a 48V electrical architecture.

As seen on the prototypes, a new front bumper and revised grille are on their way. However, a more discerning gaze might spot new sensor modules at both ends of the front bumper. This could mean that the Porsche Panamera might feature advances in semi-autonomous systems.

The refreshes are more than just skin-deep. Porsche is planning to introduce its first mild-hybrid powertrains for the Panamera. The S and 4S models will employ the same 2.9-litre twin-turbocharged V6 motor. Both variants are likely to adopt a 48V electrical architecture.

This allows the addition of a mild-hybrid system, using the integrated motor generator to recover electrical power to provide an efficiency boost, allowing the start-stop system to activate sooner. However, the typical Porsche customer is not out to eke the maximum efficiency from his sporting sedan or estate. More significant to the refresh is the inclusion of Audi’s electric compressor system, taking up the torque slack until the turbochargers spool up.

Semi-autonomous driving features and more advanced infotainment features are also part of the Panamera refresh.

The Porsche Panamera already sports the latest interior that Stuttgart has to offer, so expect more technology changes inside than cosmetic updates. Of course, this being a mid-cycle refresh, no dramatic changes are on the cars apart from more advanced infotainment features.

While Porsche is updating the Panamera for the next few years, the real news everyone around the world is waiting for is that of the Taycan. Slated for launch in September, Porsche’s first all-electric car has already garnered a lot of hype around it. A 600hp Porsche EV that can cover close to 450km on a charge, what’s not to like?
