Talk:FTP-75

On the HWFET: "The measurements are adjusted downward by 10% (city) and 22% (highway) to more accurately reflect real-world results." where does it say so in source [3] and why would it be adjusted downward by this amount? also there's not really a city or highway part in the HWFET which is highway only?

Maintenance, expert input
I did some maintenance on the driving cycles pages, but more work needs to be done. Specifically, I added some links to the United States and UNECE regulations that describe the cycle. In these references it is possible to get the actual speed vs. time data, so eventually new graphs can be produced to illustrate the article, as the current graphs are not vectorised.

The article describes the driving cycle, therefore, I do not know if an extensive discussion on how to measure the fuel efficiency or electric consumption is necessary. I think readers would appreciate that an expert (a technician doing these tests him or herself) explains the actual steps done in the industry based on his or her experience, with reference to standards of course, however this would overlap, I presume, the content on the article fuel economy in automobiles.

So, this is what I would like an expert to address: 2001:4CA0:2216:0:CCD2:B6B4:9D27:140E (talk) 11:25, 27 April 2014 (UTC)
 * Only the driving cycle, or
 * Driving cycle and test procedure for fuel consumption
 * New graphs for the driving cycles
