This GTR prescribes a test cycle and test procedures to measure the emissions (including off-cycle) and fuel efficiency of light-duty vehicles. The GTR was adopted at the March 2014 session of the World Forum.

A supplemental "phase 1b" is underway to refine certain elements of the initial regulation. WP.29/AC.3 expects to consider a proposal for Amend. 1 to UN GTR No. 15 in November 2016 as result of Phase 1b activities.

A second phase is expected to address low ambient temperature, high altitude test procedures, and possibly durability and conformity issues.

A third phase would eventually include the addition of reference fuels, correlation across existing regional/national cycles, and introduction of emissions limits.

The latest draft version of the amended GTR is regularly updated by the WLTP informal working group.

The regulation is also supplemented by a gearshift calculation tool.

R83 covers emissions from all light vehicles (M1/N1) regardless of engine type and from heavier vehicles only if equipped with a gasoline engine. Under certain circumstances, R83 or R49 can apply to light vehicle CNG/LPG engines as well as to medium passenger and commercial vehicles (M2/N2) equipped with diesel engines. R83 also contains provisions specific to hybrid variations of the vehicles under its purview. Motor Vehicle Emissions Motor Vehicle Emissions UN Regulation No. 83 UN R83

9 May 2019 9 May 2019 | Why Aren’t Americans Plugging in to Electric Vehicles? Electric Vehicle Safety Electric Vehicle Safety GTR No. 20 GTR No. 20, To one degree or another, automated driving technologies take over functions previously assured entirely by the driver. At one level, driver assistance systems aid the driver in controlling the vehicle. However, technologies have advanced to the point where automated systems propose to replace the driver in controlling various aspects of vehicle behavior. For example, lane-keeping assistance systems propose to intervene in the steering of the vehicle in order to maintain the vehicle within a lane of travel. At the furthest point in the spectrum, autonomous vehicles propose to assume full responsibility for vehicle behavior without any driver intervention. As a result, such technologies undermine the fundamental assumption that the driver is responsible for the vehicle and thus present the regulatory community with a host of unprecedented opportunities and challenges in ensuring road safety. WP.29 has undertaken to address these issues on a global basis in order to seek uniform worldwide responses that will promote the use of these technologies while ensuring their safe introduction into road traffic.
