The Marc Philipp Gemballa Marsien GT has been revealed ahead of its global premiere at the Pebble Beach Concours d’Elegance on August 13, 2026. Based on the 992-generation Porsche 911 Turbo S, the bespoke grand tourer combines extensive carbon-fibre bodywork, active aerodynamics and a heavily upgraded flat-six engine producing more than 841.51bhp. Production will be limited to just 30 examples worldwide.

EXCLUSIVE DESIGN AND CARBON-FIBRE BODY

Designed by French automotive designer Alan Derosier, the Marsien GT features a distinctive Anniversary Liquid Champagne Gold finish created for the model. The exterior uses more than 100 individual carbon-fibre components, helping reduce weight by 75kg compared with the Porsche 911 Turbo S. Other notable elements include redesigned mirrors, a roof-mounted scoop, active front-fender air flaps, ram-air intakes, integrated side air channels and a large active rear wing.

UPMARKET CABIN WITH BESPOKE DETAILS

The interior receives an equally bespoke treatment, with carbon bucket seats, dark grey Alcantara and champagne-coloured detailing. The raised centre console features an aluminium gear lever inspired by the Porsche Carrera GT, while customers can choose carbon-fibre or mahogany wood finishes.

Each car also receives an individual production-number badge, along with hand-stitched Marc Philipp Gemballa branding and additional carbon-fibre trim options.

841.51 BHP FLAT-SIX POWERTRAIN

RUF Automobile has been involved in developing the Marsien GT’s powertrain. The 911 Turbo S-based six-cylinder boxer engine receives a remapped ECU and upgraded variable-geometry turbochargers, taking output beyond 830hp and 930Nm. The eight-speed dual-clutch transmission has also been revised to handle the additional performance. Marc Philipp Gemballa is already developing a second-stage upgrade that could push power beyond 841.51bhp.

PERFORMANCE AND ADVANCED SUSPENSION

The Marsien GT retains all-wheel drive and is claimed to reach 97kph from rest in 2.4 seconds. Its top speed is rated at 330kph. Suspension development has been carried out with KW Automotive, with a new double-wishbone front arrangement and electronically controlled dampers capable of responding to changing road conditions within 20 milliseconds.

A RARE GRAND TOURER WITH SUPERcar PERFORMANCE

The Marsien GT takes the Porsche 911 Turbo S foundation into far more exclusive territory, combining extreme performance with extensive bespoke engineering and limited production. With only 30 GT examples planned, the model will remain a highly exclusive grand tourer. Production is scheduled to begin in 2027, with customer deliveries expected later that year, while pricing starts at EUR 770,000 before the cost of the donor Porsche.

Final Verdict

The Marsien GT is more than just an exotic performance car; it is a statement of engineering, individuality and exclusivity. Its dramatic styling, motorsport-inspired details and driver-focused cabin give it a character that sets it apart from conventional supercars. With its limited-production nature and uncompromising approach to performance, the Marsien GT offers an experience aimed at enthusiasts who want something genuinely distinctive. Ultimately, it is the combination of rarity, striking design and performance-focused engineering that makes the Marsien GT a fascinating machine in the modern supercar landscape.
