(February 28, 2018) ATLANTA — The Porsche motorsport department is presenting Weissach's latest treat at the Geneva Motor Show — the 2019 911 GT3 RS with a race-bred chassis and a high-revving four-liter, naturally aspirated engine producing 520 horsepower and 346 lb.-ft. of torque.

Based on the 911 GT3, the RS has been refined even further, combining the most powerful naturally aspirated engine ever fitted to a road-legal 911 with a suspension that features recalibrated rear axle steering tuned for maximum dynamics and precision.

The new 911 GT3 RS accelerates from 0 to 60 mph in 3.0 seconds, which is 0.2 seconds quicker than the current 911 GT3 with PDK and 0.1 seconds quicker than the previous 911 GT3 RS. Top track speed of the GT3 RS is 193 mph.

Aerodynamics and lightweight construction have determined the design of the wide, weight-optimized body with its classic fixed rear wing. Like on the 2018 911 GT3, the front and rear fascia are made of lightweight polyurethane. Additionally, the front trunk lid and fenders on the 911 GT3 RS are made of carbon fiber and the roof consists of magnesium.

Like on the 2018 911 GT2 RS, NACA ducts in the front trunk lid optimize brake cooling without increasing drag. The front fascia features a spoiler lip that is larger than on the previous model, increasing downforce in conjunction with the larger side skirts. At the rear, the large wing mounted on the carbon fiber deck lid works in combination with a rear underbody diffusor. The result: The 911 GT3 RS produces more than twice as much downforce as the regular 911 GT3 at 124 mph.

The race-inspired appearance continues in the interior. Full Bucket Seats with carbon fiber reinforced backrests provide a high degree of lateral support to suit the vehicle's exceptional level of lateral grip. Lightweight glass for the rear window and rear side windows, lightweight door panels with door opening loops, reduced sound insulation, and the omission of rear seats emphasize the consistency of the material choices and the dedication to saving weight. The Alcantara steering wheel measuring 360 mm in diameter features a yellow 12 o'clock center marker.

The four-liter, naturally aspirated flat-six engine from Porsche pushes the sports car to new limits delivering 20 horsepower more than the engine in the 2016 911 GT3 RS and the current 911 GT3. Plasma coated cylinder liners, a central oil supply through the crankshaft with larger bearing diameters, larger connecting rod bearings and the rigid valve train with shims to provide valve clearance compensation all carry over from the 2018 911 GT3.

Capable of up to 9,000 rpm like the regular 911 GT3, the thoroughbred engine takes in ram air through openings in the rear quarter panels, and it is closely related to the unit used in current Porsche 911 race cars.

The unmistakable flat-six sound escapes the exhaust tips, which are made of titanium like the muffler itself. The engine is mated to a specifically tuned seven-speed PDK, which features performance-oriented gearing with the top track speed being reached in seventh gear, like all GT tuned PDK transmissions.

The 2019 911 GT3 RS is available to order now and is expected to reach U.S. dealers this fall. The MSRP is $187,500, not including available options or the $1,050 delivery, processing and handling fee. The Weissach Package is available for $18,000. The magnesium wheels can be ordered for an additional $13,000 in conjunction with the Weissach Package and will be available at a later date.
