Porsche is testing a new SUV prototype expected to replace the current gasoline Macan by 2028. The latest spy photos from Nürburgring reveal significant development in both the exterior layout and interior design. The SUV, known internally as project “Octan,” is still using the Audi Q5 body as a disguise, but the prototype is moving closer to its final production form.
Prototype Shows Revised Front and Wider Track
The prototype remains a mule wrapped in an Audi Q5 shell, but distinctive changes are visible. The headlights have been raised to a higher position, with large provisional openings around them. These areas reveal big intercooler radiators behind generous air intakes, though these are temporary parts. Porsche has added many small sensors on the sides, which measure forces on key structural points during testing.
The wheel arches appear filled out to cover a wider track than the Q5’s. This suggests Porsche is changing the SUV’s underpinnings to improve handling and stability. The additions also serve to lower aerodynamic drag and reduce noise. Underbody panels carry tooth-like extensions in critical areas, a common Porsche method to fine-tune airflow and performance during development. The rear bumper design hasn’t changed compared to earlier mule versions.


Interior Moves Toward Porsche’s Traditional Layout
Inside, the fake Audi displays have been replaced by a more Porsche-like setup. The prototype now features a digital instrument cluster behind a classic hood. A touchscreen sits on the centre console in a relatively conventional arrangement. This signals a move away from Audi’s curved digital displays toward Porsche’s more traditional control style.
The cabin isn’t final but shows clear progress. Porsche has been developing this SUV for over 18 months, and these changes suggest it is moving fast toward production-ready prototypes. These units may already be undergoing testing at Porsche’s Weissach facility before hitting public roads later this year.

Gasoline Engines and Hybrid Options Expected at Launch
It’s confirmed that the successor to the combustion-engine Macan will arrive around mid-2028. The new model will offer petrol engines including four- and six-cylinder variants with differing levels of hybrid assistance. Strong plug-in hybrid versions with eight-speed automatic transmissions and all-wheel drive will also be available.
Development costs are high, including a reported €1 billion license fee paid to Audi to modify the Q5’s platform with Porsche’s technology. Whether this investment will pay off depends on how well the final product meets expectations in driving, luxury, and brand value.
