Introduced in November 2014 at the LA Motor Show, the 991 Carrera GTS sits between the Carrera S and GT3. Base options included with purchase: power output of 430 PS (316 kW; 424 hp), Sport Chrono Package, Sport Exhaust System, Dynamic Engine Mounts, 10 mm lowered suspension, Porsche Torque Vectoring (PTV) system, LED daytime running lights with Porsche Dynamic Lighting System (PDLS), Sport Design Front Spoiler, Sport Design Side Mirrors, GTS badging, and 20-inch centerlock wheels. When optioned with PDK, acceleration from 0–97 km/h (0–60 mph) is achieved consistently at 3.8 seconds with the help of Launch Control.[citation needed] The 2016 model year also brought about the Rennsport Reunion Edition, limited to 25 cars, which featured a Fashion Grey livery and a 436 PS (321 kW; 430 hp) naturally aspirated 3.8-liter flat-six engine available exclusively with a manual transmission. It also included 18-way power sports seats, PASM adaptive suspension, Bose audio system, rear parking sensors, carbon-fiber dashboard trim, 20-inch sport classic wheels, adaptive headlights (PDLS, or Porsche Dynamic Light System), and a host of decals for the hood, doors, roof, and decklid plus a key fob painted the same Fashion Gray as the car, and a special leather case for the key with “911 Carrera GTS Rennsport Reunion Edition” lettering.
Porsche launched the RS version of the 991 GT3 at the Geneva Motor Show in 2015. Compared to the 991 GT3, the front fenders are now equipped with louvers above the wheels and the rear fenders now include intakes taken from the 911 Turbo, rather than an intake below the rear wing. The roof is made from magnesium. The interior includes full bucket seats (based on the carbon seats of the 918 Spyder), carbon-fibre inserts, lightweight door handles and the Club Sport Package as standard (a bolted-on roll cage behind the front seats, preparation for a battery master switch, and a six-point safety harness for the driver and fire extinguisher with mounting bracket).
The 3.8-litre unit found in the 991 GT3 is replaced with a 4.0-litre unit generating a maximum power output of 500 PS (368 kW; 493 hp) and 339 lb·ft (460 N·m) of torque. The transmission is PDK only. The car is able to accelerate from 0–100 km/h (0–62 mph) in 3.3 seconds (0.6 seconds quicker than the 997 GT3 RS 4.0) and to 0–200 km/h (0–124 mph) in 10.9 seconds. The 991 GT3 RS also comes with functions such as declutching by "paddle neutral" — comparable to pressing the clutch with a conventional manual gearbox – and a Pit Speed limiter button. As with the 991 GT3, there is rear-axle steering and Porsche Torque Vectoring Plus system with fully variable rear axle differential lock.
ntroduced in late 2012, the 991 Turbo has a twin-turbocharged 3.8-litre flat-6 engine generating 520 PS (382 kW; 513 hp) and 620 N·m (457 lb·ft) of torque.[25] The S version has an upgraded version of the engine generating a maximum power output of 560 PS (412 kW; 552 hp) and 700 N·m (516 lb·ft) of torque, but the torque is pushed to 750 N·m (553 lb·ft) with overboost function. Both of the versions have all-wheel drive. The Turbo and Turbo S was available exclusively with 7-speed PDK. The Turbo S can reach 100 km/h (62 mph) in 2.9 seconds as claimed by Porsche but has achieved 2.6 seconds by many car magazine tests. New technologies featuring adaptive aerodynamics and rear wheel steering are included as standard.
In October 2017, Porsche announced the 911 Carrera T (Touring), offering the base Carrera drivetrain but with shorter rear axle ratio, mechanical differential lock, PASM Sport lowered suspension, Sport Chrono package and sports exhaust as standard. Additional features include a reduced sound insulation, light-weight glass side/rear windows, Sport-Tex seats, a shortened shift lever, deletion of the rear seats and communication system (with their re-addition available as a no-cost option), Carrera S wheels, as well as optional rear-wheel steering, PDK transmission and bucket seats.
