This Modified 911 Turbo S Wears 959-Esque StylingMarc Philipp GemballaMarc Philipp Gemballa revealed the Marsien GT, the brand's second model, as a roadgoing version of the Marsien off-road supercar from 2024.Based on the 992 Porsche 911 Turbo S, the Marsien GT sources 830 horsepower from an RUF-tuned twin-turbocharged six-cylinder boxer engine.Production is limited to 30 units, with pricing for the GT conversion starting at $888,660 (based on current exchange rates), sans the necessary donor car.Have some sympathy for the Porsche collectors out there. They've got every 911 from the history books in their collection, but they can't quite justify the roughly $2 million required for a 959. Still, they'd really like one, and who can blame them? That's where specialists such as the folks over at Marc Philipp Gemballa come in. The company started with the Marsien off-road supercar in 2024, and now it's back with the roadgoing Marsien GT, which turns new(ish) 911s into 959 lookalikes.Marc Philipp GemballaLike the Marsien before it, the GT is built from a 992.1-generation 911 Turbo S. From a styling standpoint, the Marsien GT is pure Porsche 959. The bodywork is made entirely from carbon fiber, and it's nearly entirely new compared with the first Marsien. According to Marc Philip Gemballa, only the doors and the roof are shared between the two—and the latter now hosts an intercooler-feeding scoop. The fuel cap is now located centrally on the hood, and there are active louvres on the front fenders and an active rear wingAdvertisementAdvertisementThe suspension, which has been tuned for the road rather than dunes like with the first Marsien, has been lowered to a standard ride height just under four inches off the ground. The setup uses an unequal-length control arm design that was developed specifically for the Marsien GT, paired with electronically controlled dampers that continuously adjust their compression and rebound forces.Like any 911 (or 911 adjacent) car worth its salt, the Marsien GT is powered by a flat-six. This one was tuned by the team over at RUF. It's twin-turbocharged and makes 830 horsepower and 603 pound-feet of torque. The automaker claims a 2.4-second zero-to-60 mph run and a top speed of 205 mph—with both figures carrying the caveat that they require a set of Michelin Pilot Sport Cup 2 tires to complete the job.If, for some reason, the thought of 830 horsepower doesn't quite excite you, Marc Philipp Gemballa announced that it is currently developing a more powerful unit that produces over 900 horsepower. That ought to do it for you.The Marsien GT is a bit more exclusive than its off-roading predecessor. While the company built 40 of the original Marsien, Marc Philipp Gemballa said this new version will be limited to just 30 units, bringing the total run of Marsiens to 70 vehicles worldwide. Pricing for the GT conversion starts at around $888,660, based on current exchange rates. Customers will need to budget sizably more, though, as that price does not include the necessary donor car or any of the plentiful options available for customization.➡️ Skip the lot.
