Porsche 911 Generations Compared
As the next chapter in the storied heritage of the Porsche 911, the new 992 marks the beginning of the latest evolution of the world’s most iconic sports car. Debuted in 2012, the outgoing 911 generation carried the 911 into the future with enhanced performance and a driver-focused interior. The all-new 991 continues this exceptional pedigree while staying true to its legacy. If you’ve been wondering exactly how these two generations are different from one another, Porsche Ann Arbor has created this side-by-side comparison which examines the distinctions between the 992 and 991 generations.

While the 992 remains true to the iconic shape of the model, there are a few significant distinctions which separate it from the outgoing 991 generation.
Front – Up front, the hood of the 992 features sharper edges as opposed to the curved nature of the 991 hood. This sculpted hood design pays tribute to 1970s 911 models. Similarly, the oval-shaped air vents of the 991 now have a more rectangular appearance on the 992.
Side Profile – A key attribute of the Porsche 911 is its ability to continue forward while preserving the iconic profile of the vehicle. The 992 generation carries the powerful wheel arches and signature sloping rear pillar that have made the 911 instantly-recognizable worldwide. Some slight updates include revised door handles and rounded door seams.
Rear – Perhaps the most noticeable design differences between the 992 and 991 are evident when both models are viewed from the rear. Wider and more eye-catching than ever before, the all-new 911 now includes an expansive thin [BK3] set of taillights which stretch across the engine cover. This stylish complement gives the rear end a sense of symmetry. You’ll also notice more prominently flared rear fenders and a re-imagined lower fascia.

There are also some key differences between the interiors of both the 992 and 991 generations. Showcased inside the all-new 911 is a revised digital layout placed inside the wide dash featuring prominent straight lines. Contributing to the minimalist look of the 992, the collection of physical buttons previously found inside the 991 have been replaced. Their functionality has been transferred to a massive 11-inch touchscreen now found in the center of the dash. Other new options include an available 360-degree camera system and an available night-vision system. Despite the changes, one essential element remains unchanged. The tachometer remains positioned front and center within the instrument cluster. The iconic driving position of the 911 is also preserved inside the 992 generation.

Several revisions and updates have been made to the powerful lineup of turbocharged engines offered on the all-new Porsche 911. An enlarged central intercooler is found at the rear, offering a more balanced system than the twin intercooler units fitted to the 991 generation. This engineering development has resulted in a 12% larger size which lowers intake-air temperatures. Improved exhaust manifold flow helps boost power delivery on the 992. Compression ratios within the engine have been increased from 10.1:1 to 10.5:1 while maintaining a boost pressure of 16-psi. As a result, the horsepower output of the Carrera S has increased from 420 to 450. While the brake rotors remain the same size, the newly-optional PBSB (Porsche Surface Coated Brake) system provides greater stopping power.
Consistently ranked among in the segment, the proven Porsche PDK automatic transmission has received some changes for the 992 generation of the Porsche 911. Gearing has increased from 7 to 8 speeds for the all-new 911, making no compromises on either performance or fuel economy. In fact, this new unit saves space in the drivetrain. The gearshift for this new transmission is noticeably smaller than the one found inside the previous generation as well.
