If you google for the right stuff you will find some of these conference papers. you will certainly find a lot of governmental test data. You will even find some industrial references and test data on start stop system on power generation.
You will also find a lot of crap. The crap, I hate to say, is typically generated by car forums, full of opinions and maybe some individual measure that just don’t hold water as far as I’m concerned. Also, car news sites are notoriously badly informed on this topic. Quote:

Although the urban cycle might be a reference or base line, it doesn’t reflect my driving style or anybodies for that matter. So I’m not sure how to relate or extrapolate any test results in an urban cycle to my personal situation.
So unless somebody can convince me what my FE gains would be based on these urban cycle they are meaningless statistical data.
Just be slightly altering my driving style I can increase or descrease my FE by far more then 6-8%. Quote:

maybe, it really depends on the number of start/stops in a give time frame against the otherwise idle time Quote:

Good, it seems our biggest difference is around what you can find with google!
