Although the 992 generation Porsche 911 stays true to the instantly-recognizable look of the model, there are numerous key changes which differentiate it from the outgoing 991 generation.

Front – At the front, you’ll notice sharper hood edges instead of curves. Rectangular air vents replace the oval-shaped look of its predecessor. Its sculpted hood returns as well, paying tribute to 911 models of the 1970s.

Profile – One of the most unique design features of the Porsche 911 is how meticulously the iconic profile of the vehicle is preserved. From its signature sloping rear pillar to its powerful wheel arches, the exterior shape is very similar to the previous variant. Some subtle changes you’ll notice include revised door handles and rounded door seams.

Rear – The biggest design changes are visible when you view both the 992 and 991 from behind. Now wider and more aesthetically pleasing, the 911 now features an expansive thin set of taillights that spans across the engine cover. This adds an eye-catching symmetrical look to the 992. A re-sculpted lower front fascia and more prominently flared rear fenders add another aggressive touch as well.

When you compare the interiors of both the 992 and 991, you’ll immediately recognize some noticeable changes. Taking center stage inside the 911 is its new digital layout set inside a wide dash featuring prominent straight lines. Adding to the sleeker interior look of the 992, the array of buttons found inside the 991 have been removed. Their functions are preserved within the massive 11-inch touchscreen found in the center of the dash. Other new features include an optional night-vision system along with an available 360-degree camera system. Sure to be appreciated by all 911 drivers, one key component remains the same. The tachometer is placed front and center in the instrument panel for easily visibility. The superb driving position of the 911 remains preserved inside the 992 generation.

There are numerous revisions and tweaks to the powerful turbocharged engines of the 992 Porsche 911 generation that are worth mentioning. A larger central intercooler is found at the rear, replacing the twin intercooler units of the 991 generation. This change results in a 12% larger size that allows for lower intake-air temperatures. Better-flowing exhaust manifolds also help power delivery on the 992. Engine compression ratios have increased from 10.1:1 to 10.5:1 while maintaining 16-psi of boost pressure. Carrera S horsepower outputs increase from 420 to 450 as a result. Although brake rotor sizes remain the same, the newly optional PBSB (Porsche Surface Coated Brake) system helps enhance braking performance.

Among the most revered in the segment, the legendary Porsche PDK automatic transmission has undergone some changes for the 992 generation of the 911. Gearing has increased from 7 to 8 speeds for the current-gen 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.
