For electric vehicles, for example, a car with a range of 400 km according to the NEDC has a range of only slightly over 300 km according to the WLTP. Novel WLTP Cycle PN emissions levels are 2 to 3 times higher at the 600 m³/h, on average. There is an impact in the PN size distribution depending on the Brake conditions (speed, temperature, etc.). The WLTP test consists of four parts depending on the maximum speed: Low (up to 56.5 km/h), Medium (up to 76.6 km/h), High (up to 97.4 km/h), Extra-high (up to 131.3 km/h). These parts of the cycle simulate urban and suburban driving and driving on extra-urban roads and motorways. In principle, the WLTP cycle corresponds to the natural evolution of the previous NEDC standard , according to which each car was subjected to a set of tests attesting to its actual consumption. Going into the details, WLTP is the acronym of Worldwide (harmonized) light (vehicles) test procedure, that is a test procedure also intended for light The new WLTP laboratory test cycle is longer than the NEDC cycle in both time and distance - cars are now driven for 30 minutes and around 14 miles, compared to 20 minutes and less than seven miles.

Going into the details, WLTP is the acronym of Worldwide (harmonized) light (vehicles) test procedure, that is a test procedure also intended for light The new WLTP laboratory test cycle is longer than the NEDC cycle in both time and distance - cars are now driven for 30 minutes and around 14 miles, compared to 20 minutes and less than seven miles. The New European Driving Cycle (NEDC) and the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) are two type approval tests with the same purpose: to measure regulated pollutants and particle matter emissions, as well as fuel consumption on new cars. The old lab test – called the New European Driving Cycle (NEDC) – was designed in the 1980s and became outdated today due to several evolutions in technology and driving conditions. The European Union has therefore prepared a new test, called the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) that applies from September 2017. 1. Defined Cycle (WLTP-Brake Cycle) --- Topic closed Decision is to run the time based WLTP-Brake Cycle profile. The aim is to adjust the cooling air volume for the different dynos.

The "New European Driving Cycle" (NEDC) was initially developed as a theoretical measurement run and has been in application Europe-wide since 1992. A  The previous lab test – called the New European Driving Cycle (NEDC) – was designed in the 1980s. Due to evolutions in both technology and driving conditions,  Find out about the new WLTP (Worldwide Harmonised Light Vehicle Test taxed according to the CO2 emissions figure measured under the WLTP test cycle. They are based on standardised driving cycles (length, speed, equipment, temperature, etc) and measure pollutants, CO2 emissions and fuel consumption for  The old NEDC (New European Driving Cycle) is being replaced by the new WLTP (Worldwide Harmonized Light Vehicles Test Procedures) which is a longer   The WLTP driving cycle is divided into four phases, each with different average speeds: Low, Medium, High and Extra High.

Introduced in 1992, the NEDC protocol (New European Driving Cycle) has become outdated and has been gradually replaced by the WLTP protocol (Worldwide Harmonized Light Vehicles Test WLTP procedure: WLTP uses new Worldwide harmonised Light-duty vehicle Test Cycles (WLTC) to measure fuel consumption, CO 2 and pollutant emissions from passenger cars and light commercial vehicles. The new protocol aims to provide customers with more realistic data, better reflecting the daily use of the vehicle. WLTP procedure uses Worldwide harmonised Light duty vehicles Test Cycles (WLTC) to measure fuel consumption, CO₂ and pollutant emissions from passenger cars and light commercial vehicles, taking into account the specific characteristics of the individual model … The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) This page was last updated on 1st April 2021 The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) replaced the NEDC test procedure for establishing the official Fuel Consumption and CO2 emissions of new cars in September 2017, which became mandatory for all new cars (powered by an Internal Combustion Engine) by September 2018. Today we’ll talk fuel economy - the stuff that manufacturers tell us, and results I give you in my reviews. Every now and then you ask me, where do my result WHY IS WLTP ON THE WAY? Because the NEDC (New European Driving Cycle) – the current measuring cycle last updated in 1997 – has long been criticised by specialists and the public for the unrealistic data it produces (the test cycle is too lenient, doesn’t respond to current traffic and doesn’t take optional equipment into account).
