About this car

The 2018 Porsche 911 GT3 delivers uncompromising performance in a Chalk-finished coupe body with a Black leather interior. Powered by a 4.0L H6 engine producing 500 horsepower and 339 lb.-ft. of torque, this rear-wheel-drive model pairs the flat-six with an automatic transmission and features a rear locking differential, variable intake manifold, and variable valve control. With just 12,649 miles, the GT3 combines track-focused engineering with everyday usability through its adaptive suspension, sport suspension, and 20-inch alloy wheels fitted with performance tires sized 245/35YR20 front and 305/30YR20 rear.

Inside, the two-seat cabin centers on supportive bucket seats with power adjustment for both driver and passenger, a sport steering wheel, and a front center armrest. The cabin stays comfortable via automatic temperature control with front dual-zone A/C, while the navigation system, 7.0-inch primary LCD, SiriusXM satellite radio, CD-MP3/DVD-Audio playback, and Apple CarPlay integration keep the driver connected. Bluetooth wireless phone connectivity, an 11 GB internal memory system, and two 1st-row LCD monitors complete the entertainment suite.

Exterior equipment includes body-color bumpers and door mirrors, heated and power-adjustable mirrors, a rear spoiler, and Bi-Xenon high-intensity discharge headlights with headlight cleaning and delay-off functionality. Additional visibility features comprise an exterior parking camera rear, rear fog lights, variably intermittent wipers, and a rear window defroster, while perimeter/approach lights and a fully automatic lighting system enhance presence and security.

About the Porsche 911 GT3 991

Production: 2011–2019
Cylinders: 6
Powertrain: Combustion
Body: Coupe

The Porsche 911 GT3 (991 generation) was produced between 2013 and 2019, marking a significant evolution in Porsche’s high-performance lineup. Approximately 10,000 units of the 991 GT3 were manufactured across its variants, including the standard GT3, GT3 RS, and limited editions, making it relatively rare compared to base 911 models. It is powered by a naturally aspirated 3.8-liter flat-six engine in early models, upgraded to a 4.0-liter in later versions (2017-2019), delivering between 475 and 520 horsepower depending on the variant. Performance highlights include a 0-60 mph time of around 3.0-3.5 seconds and a top speed exceeding 195 mph, with the GT3 RS achieving track-focused aerodynamics and handling.

For exotic car collectors, the 991 GT3 holds appeal due to its rarity, especially in manual transmission configurations offered in later years (991.2), and special editions like the GT3 Touring Package, which prioritizes understated styling. Historical significance lies in its return to a purist driving experience, with Porsche responding to enthusiast demand for manuals. Value trends show steady appreciation, particularly for low-mileage examples and RS variants, often fetching premiums in the $150,000-$250,000 range at auctions as of recent market data.
