I don't believe this is true for all cars, I'm sure the manufactures test every engine before dropping them in to the cars but track testing every single unit Not likely, way to much work and to much time. They test a hand full of them to make sure the components work as they should. Once the consumer gets their hands on it other problems may arise and those problems are handled as "Recalls".
My golf was brand spanking new, my trip odometer says 114 miles so does my engine odometer. No one drove my car, it had all the plastic still on it. They just cleaned and prepped it.
:facepalm:
Yes......bud, EVERY single car.
I have literally watch these cars drive off the line (At Mercedes US INTL AND Honda Mfg.) and onto the rolls test and bump test. 100% Broham. You're confusing track testing for the 2 mile test track scenarios that are only used up at R&D for new model testing. (FYI those tests are ALWAYS fun to do, might have a buddy lucky enough to do it for the NSX).
We do have quality checks that are windnoise, NVH, driver experience, etc. etc. about 10 times a day but thats a different story. That data is collected and measured and analyzed every day.
FYI your ABS is fully broken in as well before it leaves the factory. The ear piercing screech you hear around the rolls test is a very very good indicator of that. Each wheel is tested individually as well as a full reverse up to 15MPH and a HARD stop. 4WD Drive models get an even harder test.
Bump test is done 100% on a roll in 4post shaker after the roll test.
Waterleak testing is done after the roll test to indicate if anything was installed wrong or fell loose during the 4post shaking.
100%. 680 Vehicles a day. All are broken in from the factory. Shipping tape is NOT applied until after all of that happens and the vehicles are handed off to a third party for transport and placed onto trucks and trains.
EDIT: I'm also responsible for many miles on certain customer's vehicle due to various quality and engineering testing. We had some issues that we had to attend to. I probably stayed on that track for about 4-5 hours going back and forth. Shit happens man, and what better way to test whats actually coming off line than to pick one up off the line and do your testing?
