MARSIEN GT
U.S. orders for the Marc Philipp Gemballa Marsien are now available through Grand Prix Motorcars.
Legendary Platform
The MARSIEN GT is the second car from Marc Philipp Gemballa GmbH, and the road-focused evolution of a program that began at Pebble Beach in 2021. Where the original MARSIEN crossed between tarmac and desert, the GT commits to the road: precision driving, everyday usability, grand touring intent.
Each car starts as a Porsche 911 Turbo S of the 992 series and is then rebuilt around roughly 1,500 newly engineered components - bodywork, suspension, exhaust, taillights, door handles, wiring loom, chassis systems, interior. Alan Derosier, who shaped the original MARSIEN, led the design.
Carbon and Aerodynamics
The exterior is full carbon fiber - over a hundred individual components, including air channels, mirrors, wheel arch liners, and a single rear panel running from the A-pillar to the wing. Together with a carbon underbody replacing the standard aluminium floor, the car sheds 75 kilograms against the 992 Turbo S it began as. The panels are made by German carbon specialists who also supply OEM sports car manufacturers and Formula One teams.
The active aero runs on pneumatics. Front fender louvres vent high-pressure air out of the wheel housings, cutting front-axle lift. The rear wing sits raised and angled for downforce and high-speed stability, and doubles as an air brake. A roof scoop feeds the intercoolers directly, separate ram air intakes feed the engine, and side skirt intakes cool the rear brakes.
Powered by RUF
The engine work stays with RUF Automobile - founded in 1939, and the house that built powertrains with Uwe Gemballa in the 1980s. Four decades on, the two names are back on the same car.
Uprated VTG turbochargers, revised ECU mapping, and reworked transmission settings take the twin-turbo flat-six past 830 horsepower and 930 Nm. A second-stage upgrade beyond 900 horsepower is in development. Behind it sits a bespoke titanium quad exhaust by Akrapovič - as much a signature as a component.
Precision Engineering
KW Automotive developed an entirely new double-wishbone front suspension for the GT, with multi-link at the rear and a road-focused damper system built on KW's DDC V5 technology. Two electromagnetic proportional valves inside each damper control compression and rebound independently, reacting in twenty milliseconds. A drive mode selector on the wheel shifts dampers, transmission, and engine mapping together.
Ride height sits at 100 mm, with a front-axle lift adding 60 mm for driveways and ramps. Forged aluminum center-lock wheels - 20-inch front, 21-inch rear - carry Michelin Pilot Sport Cup 2 tires.
Inside, the center console is raised around an aluminum shifter drawn from the Carrera GT. Hand stitching on the logo, paddles, floor mats, headrest, and armrest. A metal badge in the console carries the car's number out of thirty.
