Last year, TopCar announced they would build 13 units of the carbon-bodied Porsche 992 Stinger GTR Limited Carbon Edition based on the 911 Turbo S, and now the Russian tuner unveiled one of them dressed in brown carbon fiber.

Porsche is one of the early adopters of carbon fiber but none of its existing models makes such an extensive use of it as TopCar’s Stinger GTR. In fact, all of the exterior surfaces of the car are made of carbon fiber, with the set including 84 parts replacing every single stock panel besides the lighting units and the greenhouse. The new parts are made of four layers of carbon fiber (external, internal, and two structural layers) and in this case, they are painted in a “chocolate” color for a unique look.

The basic carbon conversion costs €100,000 ($113,555) but the colored carbon fiber adds another €25,000 ($28,389) into the mix. The brown shade has been used in most of the body panels although some aero components are left in bare carbon fiber for a duo-tone look. Other optional extras in this example include the Kline exhaust which could cost up to €13,935 ($15,823) if it is made from Inconel.

You have probably noticed the striking center-lock wheels with a diameter of 21 inches at the front and 22 inches at the rear. While they are not listed on TopCar’s website yet, we are sure they will cost a hefty amount of money. Moreover, they are shod in Michelin tires measuring 265/30 ZR21 at the front and 335/25 ZR22 at the rear.

Inside, the extent of the modifications, including new black and brown leather upholstery on the seats, doors, and dashboard in combination with plenty of carbon fiber accents, makes us believe that the owner ticked the “advanced interior exclusive options” feature listed for another €35,000 ($39,732).

All the aforementioned costs are above the value of the donor car. This means that each of the 13 units of TopCar’s Stinger GTR Limited Carbon Edition will cost more than double the money compared to a brand new Porsche 911 Turbo S which starts from $203,500 in the US market.

TopCar didn’t mess up with the vehicle’s powertrain, leaving the stock twin-turbo 3.8-liter flat-six producing 641 hp (478 kW / 650 PS) and 590 lb-ft (800 Nm) of torque, combined with Porsche’s all-wheel-drive system and eight-speed PDK dual-clutch transmission. The fact that all body panels are made of carbon fiber could make the car lighter resulting in better performance but we don’t know if the improvements are noticeable. Still, the stock 911 Turbo S accelerates from 0-100 km/h (0-62 mph) in 2.7 seconds and has a top speed of 330 km/h (205 mph), which we guess is fast enough for pretty much anyone.
