Unveiled at the 2016 Geneva Motor Show on March 1, the 911 R shares most of its underpinnings with the 991.1 GT3 RS, but does not include the roll cage, rear wing, and associated bodywork for a weight saving of 50 kg (110 lb). The 911 R comes only with a 6-speed manual transmission, and has a top speed of 323 km/h (201 mph) due to a lower drag coefficient as compared to the GT3 RS. It also offers additional options including a lighter flywheel and removal of the air conditioning and audio systems. Production was limited to 991 examples, as a 2016 model. Some samples may have been registered in 2017.
