Marc Philipp Gemballa has introduced the Marsien GT, a road-focused evolution of its outrageous Porsche 911-based Marsien. Where the original was designed to combine supercar performance with serious off-road capability, the new GT trades dunes and trails for high-speed road driving.
The Marsien GT is based on the 992.1-generation Porsche 911 Turbo S, but very little of the donor car’s exterior remains recognizable. Marc Philipp Gemballa replaces the body with extensively redesigned carbon-fiber panels while adding active aerodynamics, a roof-mounted intake, and styling inspired heavily by Porsche icons such as the 959.
Performance is equally dramatic thanks to a RUF-tuned twin-turbocharged flat-six producing 830 hp, helping the all-wheel-drive GT sprint from 0-60 mph in a claimed 2.4 seconds and reach a top speed of 205 mph.
This level of exclusivity and performance comes with an equally serious price. Marc Philipp Gemballa says the conversion starts at €770,000 before taxes, duties, shipping, options, or even the required donor Porsche, meaning the final bill can easily climb beyond seven figures.
The Marsien Has Come Back Down to Earth
The first Marsien was developed as an unusual mix of supercar and off-roader, complete with increased ground clearance and suspension engineered for use away from pavement. The GT takes the opposite approach, with Marc Philipp Gemballa redesigning the package specifically around road performance.
The body remains entirely carbon fiber, but the GT gains its own aerodynamic treatment, including active front fender louvers and an active rear wing. A central fuel filler, roof-mounted intake, aggressive front openings, and heavily sculpted rear bodywork further separate it from a regular Turbo S.
Those lightweight panels also help trim mass compared with the donor Porsche. Reports indicate the GT weighs around 165 pounds less than a standard 911 Turbo S despite its additional bespoke hardware.
RUF Turns the Flat-Six Up to 830 HP
Marc Philipp Gemballa again turned to RUF Automobile for the powertrain, continuing a relationship that also existed between RUF and Marc’s late father, Uwe Gemballa, during the 1980s. The GT’s upgraded twin-turbo flat-six produces 830 hp, with an even more powerful version exceeding 900 hp already under development.
Power reaches all four wheels through Porsche’s PDK transmission. On Michelin Pilot Sport Cup 2 tires, Marc Philipp Gemballa claims 0-60 mph takes just 2.4 seconds, while maximum speed is 205 mph.
Akrapovič supplies a bespoke titanium exhaust system, while KW Automotive helped develop the road-oriented suspension. Electronically controlled dampers continuously adjust compression and rebound, and a front-axle lift helps make the extremely low GT slightly easier to live with on real roads.
The Interior Gets Carrera GT Inspiration
Inside, the relationship to the 911 is more obvious, although Marc Philipp Gemballa has thoroughly reworked the cabin. Buyers can choose leather or Alcantara upholstery, accompanied by extensive carbon-fiber detailing and a raised center console.
That console takes inspiration from the Porsche Carrera GT, including a more prominently positioned gear selector. The approach gives the Marsien GT a sense of occasion that goes well beyond simply retrimming a factory Turbo S cabin.
Customization will play a major role in each build, meaning the already formidable starting price can rise substantially depending on a customer’s choices. Given the highly limited production run, few examples are likely to leave the factory with identical specifications.
Only 30 Will Be Built
Marc Philipp Gemballa plans to produce just 30 Marsien GTs worldwide. Combined with the 40 examples of the original Marsien, that will bring total production across the program to 70 vehicles.
That number carries personal significance, coinciding with what would have been Uwe Gemballa’s 70th birthday. Marc Philipp Gemballa is also careful to note that his company is separate from Gemballa GmbH, the tuning company associated with his father’s name.
Production is expected to begin in 2027, with customer cars following afterward. With only 30 slots available, the Marsien GT is far rarer than even the Porsche models that provide its mechanical foundation.
Nearly $900,000 Before You Buy the Porsche
The headline figure is €770,000, which currently works out to roughly $890,000, and that is only for the Marsien GT conversion. The price explicitly excludes the donor vehicle, taxes, duties, shipping, and additional personalization.
That makes the Marsien GT several times more expensive than the 911 Turbo S beneath it. Once the donor Porsche and options are included, spending more than $1 million on a finished car becomes entirely realistic.
For that extraordinary sum, buyers receive something far removed from an ordinary modified 911: carbon bodywork, RUF power, bespoke suspension, active aero, and production limited to just 30 examples. It may start life as a Porsche, but the Marsien GT’s price and engineering place it firmly in modern hypercar territory.
