Porsche Money Can Buy

The Marsien GT made its world premiere at the Pebble Beach Concours d'Elegance on August 13, 2026, during Monterey Car Week. The reveal follows the success of the original Marsien, a desert-racing Porsche 911-based supercar of which 40 units were built between 2021 and 2024. Every single buyer of the original Marsien optioned the engine upgrade from 750 hp to 830 hp. So Marc Philipp Gemballa made 830 hp standard on the GT. The message is clear about the kind of customer this car is built for.

The Marsien GT is a road-focused grand tourer, not a track special. The intent is a car that can be driven daily, that offers real-world usability alongside supercar performance. The 60mm nose-lift system, the adaptive dampers with 20-millisecond response time, and the standard ride height of 3.9 inches all point toward a car designed to be used rather than stored.

The Marsien GT does not modify a 911 Turbo S. It transforms one. The 1,500 custom components touch every system: powertrain, aerodynamics, suspension, body and interior. The result shares only the doors and roof with the original Marsien. Everything else has been redesigned.

The Porsche 959 was revealed in 1983 as a concept and entered limited production in 1986 and 1987. It was, at the time, the most technologically advanced production car in the world: all-wheel drive with a computer-controlled split, twin sequential turbochargers, active suspension, tyre pressure monitoring, and a top speed of 317 km/h. It won Paris-Dakar twice. It influenced every high-performance car that followed it for thirty years.

The Marsien GT draws on the 959's visual language deliberately. The wide haunches, the large rear wing, the prominent fender treatments, the overall sense of a car that is wider and lower and more present than any factory 911: all of these are references to what the 959 represented in its era. Marc Philipp Gemballa is making a statement about legacy as much as about engineering: the Marsien GT is the heir to a tradition of taking the 911 beyond what Porsche itself was willing to attempt. His father did it in the 1980s with gold-spec wide-body conversions. The son is doing it with carbon fibre, RUF engines and pneumatic active aerodynamics.

Marc Philipp Gemballa GmbH is a legally separate entity from the original Gemballa GmbH, the company founded by Uwe Gemballa in 1981 and now under different ownership. Marc Philipp established his own company in 2019, working with the Uwe Gemballa estate. The naming, the heritage references, and the family connection are explicit parts of the brand identity, but the commercial and legal structures are entirely independent.

The original Marsien, the desert-racing off-road supercar, was built in partnership with RUF, KW and other specialists. All 40 units sold. The Marsien GT is the natural progression: the same core philosophy, the same specialist partnerships, applied to a road-focused grand tourer instead of a desert racer. The 70-unit total production run (40 Marsien plus 30 GT) honours the 70th anniversary of Uwe Gemballa, who would have turned 70 in 2026. The Marsien GT is simultaneously a new product launch and a tribute. Both dimensions are fully intentional.

The Marsien GT arrives at a moment when the market for Porsche-based ultra-limited specials has never been more active. Porsche itself has no immediate hypercar successor to the 918 Spyder. That gap has been filled by a generation of small-volume specialists: Singer, Tuthill, Kalmar, RML, and now Marc Philipp Gemballa. Each takes the 911 platform as a starting point and produces something that Porsche's own product planning, homologation requirements and volume targets prevent the factory from building.

The Marsien GT's 830 hp puts it above the 911 GT2 RS (700 hp) and the Carrera GT (605 hp). Its 0-60 time of 2.4 seconds beats the Turbo S (2.6 seconds). Its production volume of 30 units makes the GT3 RS feel almost common. And its price, well over a million euros all-in, places it in a category where the buyers are not comparing it to other Porsches. They are comparing it to other expressions of what the 911 platform can become when given to someone who has no interest in the standard answer.

The market for extreme Porsche-based specials has expanded significantly in the last five years. Each approach is different. Each targets the same buyer: someone for whom the factory 911 Turbo S is not enough, but who wants their car to retain the 911 as its foundation.
