The second-generation Porsche Panamera facelift has been spotted again, and this time we’ve gotten a look at part of its interior; namely, the dashboard. Here, earlier guesses have been confirmed where the revised Panamera is seen here to feature the new steering wheel design from the 992-generation Porsche 911, though most of the dashboard architecture appears carried over from the pre-facelift car.

As such, the centre console with the haptic feedback controls remains, as do the touchscreen display and the driver’s instrumentation set with a central analogue tachometer – of a similar design as the pre-facelift Panamera’s, rather than the vintage-look item in the 992 Neunelfer – flanked by digital displays.

Judged on its exterior, the development car here appears to be the Turbo variant, with twin LED DRLs on each side of the front bumper and a split deployable spoiler on the rear bootlid. Changes for this facelift include the aforementioned front DRLs which are now spaced further apart and a different styling treatment for the top centre of the front bumper where the licence plate resides.

The full-width, three-dimensional tail lamp assembly has also been mildly revised for the update, where a central light strip now appears more integrated with the main tail lamp elements which are now closer to the upper edge, in a fashion similar to that of the Sport Turismo facelift development car sighted earlier.

The Panamera’s powertrain line-up should be similar, if not identical to that for the Panamera Sport Turismo, which is expected to include a mild-hybrid setup pairing a 48-volt electrical architecture with a 2.9 litre biturbo V6 petrol which currently serves in Porsche as well as Audi models. This should augment the 440 hp/550 Nm outputs this produces in ICE-only form, on top of improving emissions and economy.

Transmission can be expected to retain the services of the eight-speed dual-clutch automatic which the Panamera currently uses, as is all-wheel-drive. At the upper end of the Panamera ladder, the firm’s 4.0 litre biturbo V8 petrol can also be expected to continue here, in both ICE-only and plug-in hybrid forms, the latter represented by the 680 hp/850 Nm Turbo S E-hybrid in current guise.
