The 991-generation 911 was launched in 2013 on an entirely new platform, only the third since the original 1963 Porsche 911 (901)  was introduced. But, despite being less than three years old, the current 911 is set to receive a facelift in 2015. The update will include the entire lineup – although the 2016 GT3 RS  will carry over unchanged for at least a couple of years – but it seems as if the non-Turbo models are the ones to benefit from the more important upgrades. At least under the hood.

As for the 2015 911 Turbo and Turbo S  , both will get minor tweaks inside and out, and we now know that they get a bump up in power output as well. Expect the Porsche 911 Turbo and Turbo S to officially debut at the Detroit Auto Show  on January 11th. With that debut right around the corner, Porsche has finally filled us in on what we’re going to see on the updated models. Keep reading to see what you can expect when they land in Detroit early next year.

Updated 12/23/2015: Porsche dropped a new video for its new 911 Turbo in which it wants to prove that the new sports car is perfect for everyday usability. Hit "play" to watch it!

At a glance, the facelifted 911 Turbo and Turbo S are pretty similar to the models they replace, but there are some noticeable changes. Up front, there are narrow, LED daytime running lights that, along with the addition fin in the central air intake, contribute to the look of a wider stance.

To the sides, the Turbo and Turbo S have been fitted with 9x20 inch wheels up front and 11.5x20 inches in the rear – 0.5-inches wider than previous years. The wheels on the Turbo S were also redesigned, carrying a seven spoke design compared to the previous 10 spoke design. Just like the Carrera, the door handles now come without plastic inserts.

To the rear we find 3D rear lights with aura-like illumination – similar to what we see on the Carrera. The openings for the exhaust have been redesigned, as well as the dual tailpipes. The most notable design changes is the rear lid grille. It now has longitudinal louvers on the sides and a separate cover in the middle that optimizes the engine’s air inductions.

For the most part, the interior has been carried over unchanged. The facelifted model does however have an analog clock mounted to the top of the dash and there have been some technological updates as well. Both cars are equipped with the Sport Chrono Package with a mode switch and re-sponse button. The new 360 mm steering wheel will look familiar, as it has been adopted from the 918 Spyder. The mode button allows the driver to switch between Normal, Sport, Sport Plus, or Individual – all of which change the way the vehicles drives and reacts.

In addition to the steering wheel, both trims now have Porsche Communication Management with Online Navigation – a newly developed infotainment system. With a glass, multi-color touchscreen, it is mounted flush with the center console and includes the standard Connect Plus module. Navigation accesses traffic data in real time and routes can be visualized with 360-degree images and satellite images. Some vehicle functions can be controlled remotely by smartphone, which can now be connected via Wi-Fi, Bluetooth, or USB cable. Like previous years, a Bose sound system is standard and a Burmester system is available for an up-charge.

The 911 Turbo and Turbo S now come with 20 additional horsepower over previous years – bringing the Turbo up to 540 horsepower and the Turbo S up to 580 horsepower. Both cars still utilize the 3.8-liter, flat-six, but that engine has been modified in each to accommodate the power increase. On the Turbo model, Porsche modified the inlet ports on the cylinder head, added new fuel injection nozzles and increased fuel pressure. The Turbo S has received new turbochargers and larger compressors to accommodate its increase in power.

Both cars now have a dynamic boost function that effectively improves engine response by maintaining charge pressure during load changes. Essentially, fuel supply is cut when the throttle is released, but the throttle valve remains open. By doing this, the engine responses almost instantaneously with the next press of the accelerator – meaning you’ll experience better response times when shifting. Fuel consumption has been improved slightly, while performance has been improved. The Turbo S Coupe hits 62 mph from a stop in just 2.9 seconds, with a top speed 205 mph. The 911 Turbo now hits 62 mph in just 3.0 seconds with a top speed of 198 mph. In comparison to previous years, that is 7.4 mph and 3.1 mph faster, respectively. The new 911 turbo will launch in Germany starting in January 2016. The base, 911 Turbo will start out at 174, 669 Euro ($185,620,) while the 911 Turbo Cabriolet clocks in at 187,759 Euro ($199,521). The 911 Turbo S comes in at 202,872 Euro ($215,592) and the Turbo S Cabriolet starts out at 215,962 Euro ($229,502.) These prices are before available options, taxes and delivery, while the conversion rates are accurate as of the time of this writing. As always, Porsche’s facelift for the 911 is just a mild update meant to keep the sports car in line with other products in this crowded niche. The visual upgrade and the added oomph won’t do much to change the vehicle’s behavior on the road and the track, but customers expect a refresh once in a while, and Porsche needs to step up and deliver. The increased power and technological updates of the 911 Turbo and Turbo S will help these cars carry on as one of the most desirable vehicles in the world.
