. Pioneer, millionaire, bestseller: the 991 series has been the most comprehensively-developed generation of the 911 to date – and the most successful too, with 233,540 units produced. The final specimen has now rolled off the production line: a 911

991 series review
The 991 generation was launched in 2011 as one of the biggest development steps in the history of the 911. Nearly 90 percent of all components were newly designed or had undergone substantial further development. Thanks to a lightweight body made of an innovative aluminium-steel composite, it was the first time that a new 911 had weighed less than its predecessor. The chassis, which benefitted from a 100 millimetre-longer wheelbase than the model that it replaced, could be equipped with a new, optional roll stabilisation system –
The host of innovations continued in the 911
The 991 generation also proved the ideal basis for special models and radical sports cars.
And there was more to come: The fastest and most powerful 911 racing technology ever seen in a production road-going 911 appeared in 2017 in the form of the 515 kW (700 PS) 911 GT2 RS. Its naturally aspirated sister followed a few months later. The 911 GT3 RS had a racing chassis and a 382 kW (520 PS) four-litre naturally aspirated engine, perfectly combining road and race track.
Right on time to mark the 70th anniversary of

The consumption and CO2 emission values were determined in accordance with the new Worldwide Harmonized Light Vehicle Test Procedure (WLTP). The NEDC values derived from this should continue to be specified for the time being. These values cannot be compared to the values determined in accordance with the NEDC measuring procedure used up to now.
911 GT3 RS: Fuel consumption combined 13.2 l/100 km; CO2 emissions 303 g/km
911 GT2 RS: Fuel consumption combined 11,8 l/100 km; CO2 emissions 269 g/km

^ The published electricity consumption (kWh per 100 km), charging times (hours/minutes) and kilometre (km) range are estimates determined in accordance with the Worldwide Harmonized Light-Duty Vehicles Test Procedure (WLTP) – see www.porsche.com/wltp. The WLTP is the test procedure used in the European Union and does not apply in Australia, where the New European Driving Cycle (NEDC) remains the appropriate test standard under ADR 81/02. Actual figures will vary as they are dependent on many factors including driving style, road and traffic conditions, weather conditions, a vehicle’s features, equipment, accessories, condition, load and use. Extra features and accessories (attachments, tyre formats, etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics can also affect the electricity consumption and performance values of a car. The published charging times are estimated using the vehicle’s charging equipment and European charging facilities, with the battery temperature under optimum conditions and the vehicle having an initial charge status of 5%. CO2 emissions can also be generated at the power source when vehicles are being charged, unless 100% renewable energy is used. As Australian models have not been tested in accordance with the NEDC procedure, the published figures do not apply in Australia and must not be relied upon in making a decision as to whether to purchase a vehicle.
