. 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 1 September 2017 certain new cars have been type approved in accordance with the Worldwide Harmonised Light Vehicles Test Procedure (WLTP), a more realistic test procedure to measure fuel/electricity consumption and CO₂ emissions. As of 1 September 2018 the WLTP replaced the New European Driving Cycle (NEDC). Due to the more realistic test conditions, the fuel/electricity consumption and CO₂ emission values determined in accordance with the WLTP will, in many cases, be higher than those determined in accordance with the NEDC. This may lead to corresponding changes in vehicle taxation from 1 September 2018. You can find more information on the difference between WLTP and NEDC at www.porsche.com/wltp.
Currently, we are still obliged to provide the NEDC values, regardless of the type approval process used. The additional reporting of the WLTP values is voluntary until their obligatory use. As far as new cars (which are type approved in accordance with the WLTP) are concerned, the NEDC values will, therefore, be derived from the WLTP values during the transition period. To the extent that NEDC values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. They are intended solely as a means of comparing different types of vehicle. Extra features and accessories (attachments, tyre formats, etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics and, in addition to weather and traffic conditions, as well as individual handling, can affect the fuel/electricity consumption, CO₂ emissions and performance values of a car.
