The second-generation Porsche Panamera was unveiled nearly three years ago and it appears the company is working on a minor facelift for the popular model.

Recently spotted undergoing testing, this particular Panamera doesn’t look all that special as its front fascia carries over from the current model. However, bigger changes occur out back as the lower section of the liftgate is covered by white camouflage. It likely hides a new light strip which could echo the one used on the facelifted Macan or Cayenne Coupe.

Given the minor styling changes, it appears this is an early prototype for the 2020 or 2021 Panamera. As a result, the production model could incorporate additional design tweaks but nothing is official as of yet.

Little is known about the model at this point, but the Panamera lineup is pretty extensive as the entry-level variant has a turbocharged 2.9-liter V6 that produces 325 hp (243 kW / 330 PS) and 332 (450 Nm) of torque. One step above is the Panamera S which has a twin-turbo 2.9-liter V6 with 434 hp (324 kW / 440 PS) and 406 lb-ft (550 Nm) of torque.

Moving further up the ladder, the GTS features a twin-turbo 4.0-liter V8 developing 454 hp (338 kW / 460 PS) and 457 lb-ft (620 Nm) of torque. There’s an even more powerful V8 in the Panamera Turbo which packs 542 hp (404 kW / 550 PS) and 568 lb-ft (770 Nm) of torque.

There are also two plug-in hybrid variants. The Panamera E-Hybrid has a twin-turbo 2.9-liter V6 and an electric motor which enable the car to produce a combined output of 456 hp (340 kW / 462 PS) and 516 lb-ft (700 Nm) of torque.

The Panamera Turbo S E-Hybrid is even more powerful as it has a twin-turbo 4.0-liter V8 engine and an electric motor that work together to produce 671 hp (500 kW / 680 PS) and 627 lb-ft (850 Nm) of torque. This allows the car to rocket from 0-62 mph (0-100 km/h) in as little as 3.4 seconds before hitting a top speed of 193 mph (310 km/h).

Engine options will likely carry, but they could receive minor modifications for improved performance. Likewise, the plug-in hybrid variants could get a slightly longer electric-only range.
