The Marc Philipp Gemballa Marsien GT transforms the brand’s off-road supercar into a road-legal version designed for pavement. Built on the 992-generation Porsche 911 Turbo S, it replaces the original Marsien’s rugged suspension with a lower, street-focused setup and features a carbon-fiber body inspired by the iconic 959.
From off-road to on-road
The GT is the second model from the German tuner, following the 2024 Marsien off-roader. Only the doors and roof remain from the first version, with the roof now including an intercooler scoop. The rest of the bodywork is new, featuring active louvres on the front fenders and a deployable rear wing that adjusts aerodynamics automatically. The fuel filler sits in the center of the hood, echoing the 959’s design.
Its suspension uses a custom unequal-length control-arm setup with adaptive dampers that continuously adjust compression and rebound. Ride height is set just under four inches, balancing track capability and street usability. While lower than the off-road Marsien, it retains enough clearance for everyday driving.
830 horsepower, 30 units, no donor included
The flat-six engine receives tuning from RUF, increasing output to 830 horsepower and 603 pound-feet of torque. The factory Turbo S already produces 640 horsepower, so the upgrade focuses on power delivery. The tuner claims a 0-60 mph time of 2.4 seconds and a top speed of 205 mph, though both figures require Michelin Pilot Sport Cup 2 tires.
For those seeking more power, a 900-plus-horsepower version is in development. No timeline has been provided, but the company confirmed work is underway.

Production is capped at 30 units, fewer than the 40 built of the original Marsien. The conversion starts at $888,660, excluding the donor 911 Turbo S or optional upgrades. With the base Turbo S priced around $230,000, the total cost will likely exceed $1.1 million before customization.
Tuners have often tried to recreate the 959’s appeal. Its rarity—only 292 were built in the late 1980s—and its reputation as a technological milestone have made it a popular reference point. Most reinterpretations have been one-offs or small runs, but few have matched the original’s blend of performance and design. The Marsien GT emphasizes the aesthetic, offering modern reliability that the 35-year-old 959 lacks.
Exclusivity drives demand. With only 70 Marsien models of any kind in existence, owners gain a car that stands out. The driving experience may be the biggest advantage, as the original 959 delivered despite its high price.
Marc Philipp Gemballa has not shared a delivery timeline, but deposits are likely secured given the limited run. The company did not confirm whether existing Marsien owners receive priority, though some may return for this version.
A similar focus on exclusivity appears in other segments of the automotive market, where limited production runs create desirability.
