GT3 GT3 RS | Porsche 991 | Daddys-Carparts
With the introduction in 2012 of the latest GT3 model came the announcement of active rear steering. It is claimed by Porsche to provide higher lateral dynamics than previously available. Car speed inputs determine whether the rears steer in the same or opposite direction of the front wheels. It is the first GT3 offered only with automatic transmission. At the start of 2014, deliveries of the GT3 were halted following two fires. A subsequent recall to replace the engines of all 785 cars was announced in March 2014 before manufacturing of the GT3 would restart.
911 GT3 RS
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 Turbo-like intakes, 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 with 500 horsepower and 339 lb·ft (460 N·m) of torque. The transmission is PDK only. The drivetrain delivers 0-62 mph (0-100 km/h) in 3.3 seconds (0.6 seconds quicker than the 997 GT3 RS 4.0) and 0-124 mph (0-200 km/h) 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 Pit Speed limiter button. As with the 991 GT3, there is rear-axle steering and Porsche Torque Vectoring Plus with fully variable rear axle differential lock.
