The 991 Turbo is introduced 40 years after the first 911 Turbo prototype. The power figure is now exactly twice the original car. Fortunately the weight is not up two times for the heaviest 911. The 991 Turbo is 50 kg / 110 lb heavier than was the 997 Turbo 3.8 with manual gearbox. Sad news for the enthusiasts: the 991 Turbo is not available with manual gearbox / good news for the older 911 Turbo owners: their cars will not lose their value.

The PDK has the coasting function which means the gearbox is declutched from the engine under free run (like shifting to neutral with manual gearbox), so the engine can drop its rpms to idling speed and save some fuel. Now if you brake under coasting (approaching traffic lights for example), the engine is turned off. The engine in the 991 Turbo is the same unit that was in the 997 Turbo 3.8, just that fine tuning has given it 15 additional kilowatts of power to retain the power/weight ratio of the older car.

The 991 Turbo has the rear axle steering. The first Porsche to have the rear axle steering was the 991 GT3. The system was designed for the 991 Turbo in first place, but as the last moment decision it was also incoroprated into the GT3 that was launched before the Turbo. At speeds of up to 50 kmh / 31 mph, the system steers the rear wheels into the opposite direction of the front wheels simplifying manouvering and parking. Between 50-80 kmh / 31-50 mph, the rear wheels are not steered and at speeds above 80 kmh / 50 mph, the system steers the rear wheels parallel to the front wheels, so the car can easily change lane going sideways.

More show, less go - the standard wheels are 20", which are too heavy for the best performance. But most of the customers want 20" wheels and Porsche gives them. Optionally available are the radar-controlled adaptive cruise control system, camera-based road sign and speed limit recognition.

PAA - Porsche Active Aerodynamics

Porsche developed an active aerodynamic system for the 991 Turbo. It consists of a sturdy, retractable three-stage front spoiler, whose segments can be pneumatically extended, and a deployable rear wing with 3 adjustable wing positions. So, the 991 Turbo has the front and rear spoilers configurable for fast cornering on the race track or for the top speed on the straight track. In the performance position, all segments of the front spoiler are fully extended, and they generate considerable downforce at the front axle. Similarly, the rear wing is extended to its maximum height with the greatest angle of attack generating maximum downforce at the rear axle.

Turbo S

Unlike before, Porsche offers the 991 Turbo S from the start of the production of the 991 Turbo. The unique features of the Turbo S are the GT3 mirrors, slightly different front spoiler grilles and interior features. As before, the Turbo S is a heavily equipped verson of the Turbo. The powerkit adds 29 KW of power and the following equipment, optional for the Turbo, are standard for the Turbo S: PDCC Porsche Dynamic Chassis Control hydraulic rollbar system, Sport Chrono (Launch control and 0.15 bar overboost functions), dynamic engine mounts, PCCB Porsche Ceramic Composite Brakes, central lock wheels, full led dynamic headlights, adaptive Sport Plus seats (18-way adjustment, memory) and seat backrest shells upholstered with leather. The 991 Turbo S laps the Nürburgring Nordschleife in 7:27, which is 3 seconds faster than the 991 GT3.

The heavy weight of the 991 Turbo and the omission of the manual gearbox makes the 991 S WLS a choice of the enthusiast - the power-to-weight ratio is only about 5% poorer than of the 991 Turbo, but the car is 200 kg/440 lb lighter.
