. 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

* Data determined in accordance with the measurement method required by law. Since 01 September 2018 all new cars are approved in accordance with the Worldwide Harmonized Light Vehicles Test Procedure (WLTP). You can find more information on WLTP at www.porsche.com/wltp. From 01 January 2019, all fuel consumption figures are shown as determined in accordance with WLTP. CO₂ figures will be shown as NEDC-equivalent values, as CO₂ based taxation will continue to be based on an NEDC value (derived from WLTP) until 06 April 2020. For Plug-in Hybrid Electric Vehicle (PHEV) range and Equivalent All Electric Range (EAER) figures are determined with the battery fully charged, using a combination of both battery power and fuel.
Values are provided for comparison only. To the extent that fuel and energy consumption or CO₂ values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. Optional features and accessories can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics which may result in a change in fuel or energy consumption and CO₂ values. Vehicle loading, topography, weather and traffic conditions, as well as individual driving styles, can all affect the actual fuel consumption, energy consumption, electrical range, and CO₂ emissions of a car.
