You did not say you were paraphrasing, you said "the manual calls for," which I believe a reasonable person would assume to mean you are quoting. Further, your paraphrase was not accurate.That's why I did not say, "Direct quote from manual:"...partial throttle, moderate rpm, gentle braking...". I was paraphrasing.
The recommendation on avoiding heavy braking isn't to prevent mechanical damage, it's because the brakes don't achieve maximum effectiveness until broken in. And Ford's recommendation says nothing about partial throttle or moderate RPM. Indeed, occasional hard acceleration will promote, not hamper, ring seating. As an example, this instruction sheet from Mahle Motorsports--a leading international development partner and supplier to the automotive industry--is far more detailed than any Owner's Manual I've seen, and it recommends only 20-30 minutes--not 1,000 miles--of driving using part throttle and varying loads/RPM. After that, it recommends 5-6 full-throttle acceleration runs to 75% of max RPM.
I suspect the majority of break-in recommendations from auto manufacturers are less about preventing mechanical damage and more about giving a new owner time to get used to driving a new vehicle, especially one whose driving characteristics may change as components wear in.
Manufacturer recommendations for breaking in modern cars are all over the map, so words like "typical" are meaningless. Even Ford's recommendations are not consistent; the manuals for the 2021 MY and 2022 MY Bronco Sports are different. Do you think something changed between model years that required a different break-in procedure?The bottom line is -- as with essentially all vehicles ever made -- the Bronco Sport should be broken in. The typical number of miles is the 1,000 stated by Ford.
A fact is provable. To prove this claim you would have to define "most" and "hard." I get your point; it's reasonable to assume that someone test driving a vehicle is not concerned with break-in requirements (if any), but an unprovable assumption cannot be fact.Many people are hard on cars (read: ignore break-in requirements) when they test drive them. That's a fact.
A perfectly reasonable position. I get it. Again, I'm not discounting anyone's concern about their dealer allowing other customers drive their special-ordered vehicle without permission--that would annoy me as well. But my concern would not be about mechanical damage. My concern would be about my relationship with the dealer.As with so much of this stuff, it's a personal choice. My position -- speaking only for myself -- is that I do not want to pay full MSRP for a "new" vehicle that may have been thrashed.
