Marc Philipp Gemballa Marsien GT revealed with over 830hp

Based on the 992-series Porsche 911 Turbo S, the Marsien GT has been revealed ahead of its global premiere at the Pebble Beach Concours d’Elegance on August 13, 2026. Produced by Marc Philipp Gemballa GmbH, the Marsien GT is the company’s second limited-edition model – the first was the desert-focused Marsien of 2021. Including the 40 units of the latter and another 30 examples of the grand tourer (GT), there’ll be a total of 70 Marsiens produced. The 70-unit combined production run honours the 70th anniversary of Uwe Gemballa, Marc Philipp Gemballa’s father, the marque stated. 

• Has a carbon-fibre exterior, active aero and custom colour options
• Gets Michelin Pilot Sport Cup 2 tyres and an Akrapovic titanium exhaust system
• Revised six-cylinder boxer engine outputs over 830hp and 930Nm

Marsien GT design and interior

The exterior styling of the Marsien GT is the work of French automotive designer Alan Derosier. It features a one-off four-layer metallic colour called Anniversary Liquid Champagne Gold, in honour of the 70th anniversary of Uwe Gemballa. The colour is applied at a paint studio that the brand claims can “fulfil the most daring customer colour requests.” The brand also says that the Marsien GT has a full carbon-fibre exterior, consisting of over a hundred individual carbon-fibre components. The front axle-lift system has been retained from the 911 Turbo S, though.

Noticeably different elements over the donor vehicle include the uniquely shaped outside rearview mirrors (ORVMs), a top-mounted scoop, active air flaps on the front fenders, ram-air intakes, side skirts with integrated air channels, and a large active rear wing whose design is reminiscent of the Porsche 959's. Adding to these are the forged aluminium wheels wrapped in Michelin Pilot Sport Cup 2 tyres, an Akrapovic titanium exhaust system, and a carbon-fibre underfloor. All these lightweight measures ensure weight savings of 75kg over the donor vehicle, whilst the active aero features cool the brakes and reduce turbulence from the wheel arches, as per the brand.

Some of the stand-out design elements inside the Marsien GT are visible along the centre console, which itself is raised over what’s seen in the standard 911 Turbo S, but there’s also an aluminium gear lever that’s inspired by the unit found in the Carrera GT. Customers can opt this gear lever to be covered in either exposed carbon or mahogany wood, instead of softer materials like leather or Alcantara. The interior also features hand-stitched brand logo on the steering wheel, headrests, armrest and floor mats.

The centre console also sports a metal badge displaying the individual production number of each vehicle. Apart from the carbon bucket seats and dark grey Alcantara, the interior of this launch-ready example features champagne accents for much of the stitching, plus on the seatbelts and within the instrument cluster. There are also matte carbon-fibre accents and an Alcantara-trimmed roll bar. According to the brand, customers can purchase a carbon-fibre interior package that adds even more exposed carbon-fibre elements.

Marsien GT powertrain and suspension

Porsche engine specialist RUF Automobile is key behind the powertrain of the Marsien GT. Uwe Gemballa and RUF Automobile have collaborated to produce powertrains for various vehicles in the 1980s, said Marc Philipp Gemballa GmbH. Compared to the 911 Turbo S, the six-cylinder boxer engine of the Marsien GT features a remapped ECU (engine control unit) and enhanced variable-geometry turbochargers – this results in a claimed output of over 830hp and 930Nm of torque. The 8-speed dual-clutch automatic transmission (DCT) has also been revised to handle the extra power and torque.

The brand is currently working on a second-stage engine upgrade option, which will take the output to over 900hp. Even in its current avatar, the Marsien GT has a claimed top speed of 330kph and a 0-97kph sprint time of 2.4 seconds. That said, the Marsien GT retains the all-wheel-drive (AWD) system of the Porsche 911 Turbo S.

However, Marc Philipp Gemballa GmbH has partnered with KW Automotive for its car’s suspension needs. It claims that the new double-wishbone front setup has been specifically developed for the Marsien GT, with its electronically controlled dampers capable of adjusting and responding to changing road conditions within just 20 milliseconds. This suspension setup ensures that the Marsien GT offers precise control without sacrificing ride comfort that’s expected of a grand tourer, according to the brand.

Marsien GT price

The Marc Philipp Gemballa Marsien GT will be making its world premiere during the upcoming 2026 Monterey Car Week at the Pebble Beach Concours d‘Elegance in California, USA. Production will begin in 2027, with first customer deliveries commencing later the same year. The starting price of the Marsien GT will be EUR 770,000, not including the cost of the donor vehicle, i.e., the 992 Porsche 911 Turbo S. For reference, the latter starts at EUR 271,000 in Germany.
