A few months ago, Porsche was spied testing a mysterious Panamera prototype. Believed to have been internally named the Lion, it allegedly had more than 800 HP from an updated variant of the plug-in hybrid powertrain found in the Turbo S E-Hybrid.

Now, that same powertrain is thought to have made its way into the Cayenne Coupe. What makes us say that? Our spy photographers snapped a prototype of the BMW X6, Audi Q8 and Mercedes-Benz GLE Coupe rival, in the Turbo S E-Hybrid guise, featuring a few updates that could signal the arrival of an even more powerful version.

Blink and you might miss the changes, but take a second look at the lower part of the rear end and you will see them. The Turbo S E-Hybrid model has a quad-pipe exhaust system with round finishers, yet this prototype has ghastly fake pipes that flank the real central-mounted ones. Furthermore, the rear diffuser and part of the bumper are wrapped in a thin layer of camouflage in another attempt to mask the updates.

The ’hybrid’ badges on the front fenders, rear charging port on the driver’s side and shape of the front and rear bumpers are the things that suggest that this is indeed a Cayenne Coupe Turbo S E-Hybrid. Porsche’s coupe SUV range-topping variant combines a 4.0-liter twin-turbo V8 with an electric motor and has a total system output of 670 HP (679 PS / 550 kW) and 663 lb-ft (900 Nm) of torque in the standard model, yet the rumored output of the more extreme version is 800+ hp.

This would inevitably make it quicker than its Italian sibling, the Lamborghini Urus; on the other hand, the Raging Bull is apparently considering the launch of the Urus Performante variant that will be more driver-focused and boast more power, readdressing the balance within the VW Group’s brands.
