Porsche 911 R

In 2016, Porsche unveiled a limited production 911 R. It has an overall weight of 1,370 kilograms, a high-revving 4.0 L six-cylinder naturally aspirated engine from the 991 GT3 RS, and a six-speed manual transmission, while an air conditioning system and an audio system are removable options to save weight.

Current generation
Revealed at the 2016 Geneva Motor Show on March 1, the 911 R shares most of its underpinnings with the GT3 RS, but removes the rollcage, rear wing, and associated bodywork for a weight savings of 50 kg. The R comes only with a 6-speed manual transmission, and has a top speed of 201 mph (323 km/h) due to a lower drag coefficient compared to the GT3 RS. It also offers additional options for a lighter flywheel and removal of the air conditioning and audio systems. Production will be limited to 991 examples, starting as a 2017 model.
