Research on the results of the WLTP procedure for a passenger vehicle
Eksploatacja I Niezawodnosc, 2023 The article considers variables registered in the WLTP procedure. The test results of a passenger car with a compression-ignition engine have been analysed. The tests were carried out on a chassis dynamometer. The tests were performed for engine cold start and ran up to the point of reaching stabilized operating conditions.

The influence of wheel and tire aerodynamics in WLTP
2015The geometric shape of passenger car wheels can have a large influence on the aerodynamic drag of a vehicle as it has been shown already in different publications. In combination, tire and rim cause approximately 25% of the overall drag. Until now, the challenge for aerodynamicists is to find the rim / tire combination with the best aerodynamic ...

Contribution of tires and wheels to the WLTP
2019Starting in 1997, all fuel consumption and emission values in Europe were based on the so-called “New European Driving Cycle (NEDC)”. Although this cycle did not represent the typical vehicle-driver related fuel consumption values, it was very suitable for comparing cars and engines.

The challenges of WLTP emission regulations from the vehicle manufacturer’s point of view
2020Sustainability is one of the basic principles of the Daimler AG corporate strategy and a benchmark for its success concerning the entire value chain - from suppliers to products. A central aspect of Mercedes-Benz Cars is the “path to zero-emission driving” that merges three paths leading to the future of mobility: the combination of very efficient high-

WLTP – On the increased importance of aerodynamics and impact on development procedures
2016For some years a new test procedure has been developed among the UN for the determination of pollutant and CO2 emissions and fuel consumption, which should represent the average customer behaviour. Beside the EU various other countries are involved (e.g., India, Japan).

Impacts of WLTP Test Procedure on Fuel Consumption Estimation of Common Electrified Powertrains
SAE Technical Paper Series, 2019<div class="section abstract"><div class="htmlview paragraph">The new European test procedure, called the worldwide harmonized light vehicle test procedure (WLTP), deviates in some details from the current NEDC-based test which will have an impact on the determination of the official EU fuel consumption values for the new vehicles.

Road load determination in a wind tunnel compared to the WLTP wind tunnel method
2018A new type approval procedure for determination of pollutants, CO2 emissions and fuel consumption was introduced in the EU and various other countries in 2017. The WLTP (Worldwide harmonized Light vehicles Test Procedures) can be used to determine the road load of a vehicle using the wind tunnel method instead of using coast down testing procedures on ...
