MONTEREY, Calif. — The seventh Rennsport Reunion is now in full swing at Laguna Seca, serving as the ultimate gathering for Porsche enthusiasts. And amidst this international celebration of all things Porsche, the iconic automaker seized the opportunity to unveil its latest creation – the Porsche 911 GT3 R rennsport. This limited-production race car, based on the GT3 R, is specifically designed to deliver unparalleled performance on the track.
What sets the rennsport special edition apart is its departure from the constraints of traditional racing series regulations. While the regular 911 GT3 R adheres to the FIA GT3 competition rules, Porsche threw caution to the wind with the GT3 R rennsport in order to provide the 77 fortunate owners (yes, only 77 will be made) with the ultimate in performance. Visually, this means that nearly every aspect of the exterior has been reimagined, with only the hood and roof borrowed from the standard GT3 R. As a result, Porsche’s engineering efforts have yielded a race car that boasts enhanced aerodynamics and increased downforce.
For instance, Porsche replaced the traditional mirrors with cameras that provide a live feed to video monitors within the cabin. The substantial new wing required additional vertical supports to withstand the heightened levels of downforce. Additionally, the open rear fascia not only reduces weight but also grants a breathtaking view of the mechanical marvel within.
Furthermore, sidestepping powertrain regulations has allowed Porsche to extract even more power from the rear-mounted, 4.2-liter flat-six engine, which now revs up to an impressive 9,400 rpm. The output has been ramped up from 557 horsepower to 611 horsepower in the rennsport model. Porsche has equipped this version of the engine with specially-designed pistons and camshafts, and it is optimized to run on bio-ethanol fuels. However, conventional fuel can still be used without any issues. The exhaust system has been completely revamped and is now devoid of mufflers, resulting in what Porsche describes as “an authentic and extremely emotional engine sound.” Nevertheless, two optional exhaust systems are available, featuring catalytic converters and mufflers, to comply with noise restrictions at certain tracks.
The sequential six-speed gearbox remains largely unchanged, with the exception of a higher sixth gear that boosts the top speed by 12 mph compared to the standard GT3 R. The chassis, featuring a double-wishbone front and multi-link rear suspension with KW racing shock absorbers, remains unaltered as well. However, Porsche has developed a new Michelin tire compound exclusively for this car, delivering improved warm-up and drivability characteristics compared to the GT3 R.
Other minor enhancements include unique brake pads with titanium backing plates, shaving off a couple of pounds, as well as a lighter fuel tank and the removal of the air conditioning system. Admittedly, the ultra-wealthy collectors who purchase these cars with the intention of driving them may miss the air conditioning, but Porsche made it clear that weight reduction was the primary focus, aiming for a curb weight of 2,734 pounds.
These race cars are reserved for the elite, with a base price starting at a staggering $1,046,000, excluding options and transportation fees. The lucky 77 individuals who manage to secure one of these coveted vehicles can choose from seven different exterior colors and three distinctive paintwork designs. Porsche’s generous customization options for a race car include striking hues like Ruby Stay, Signal Orange, and Agate Gray Metallic. The three paintwork designs on offer are named “Rennsport Reunion Design,” “Flacht Design,” and “Speed Icon Design.”
