Progress report on test validation and refinement efforts from the Technical University of Graz (concerning the chassis dynamometer test) and TNO (concerning the road load/coast down test)

Discussion paper on “open issue 13” (and 11) concerning corrections for wind conditions that impact coast down tests and times for road load determination and ultimately the road load settings of the chassis dynamometer. This document summarizes the views of the special ad hoc group formed to consider this issue.

Discussion paper on the use of the torque meter in the WLTP coast-down methods to measure the running resistance as part of the road load determination. This document summarizes the views of the special ad hoc group formed to consider this issue.

Progress reports from TUG (chassis dynamometer corrections) and TNO (coast down corrections) covering preliminary results (as of 27.03.2014).

“Quick scan” study prepared for the Dutch Ministry of Infrastructure and Environment to evaluate the potential of “triple A” tyres to improve vehicle safety, noise emssions, fuel consumption, and CO2 emissions. Tyres in the EU are labeled to convey information on their energy efficiency, safety, and noise performance. Triple A refers to tyres receiving the highest ratings across these three criteria.
