On one hand they shouldn’t on another hand “performance modes” are often priced based on the wear and tear they induce and it’s impact on the manufacturer warranty in terms of servicing costs. Even before Tesla you already had car manufacturers that basically locked out performance behind a pay wall even tho the car itself was identical to the “sport model”. Many of the German manufacturers had this practice for a decade if not more, the extra price difference is basically their estimated cost to the changes in MTF between when you push your car to 80-90% of its capability to 100%. And even before Tesla you already had aftermarket products and services that were designed to unlock that extra performance and yes they did often at least in principal voided the warranty.

Sounds like once the car is out of warranty and the cost of maintenance falls on the owner, the incentives change and the manufacturer should pay you to run your car in "performance mode".

  When the main warranty of the car is gone you still get warranty on the parts and service you pay for out of pocket, from BMW's perspective the cost of the "performance mode" is amortized beyond the initial warranty period too. We also see this in other things too you have differential pricing in say electronics and electronic components too, sure some of it is binning but not only quite often the "enterprise" tax is just the fact that these parts will be run longer and under more stress so their MTF is different. An HDD in a home computer will be under very different loads than one in a NAS. And quite often there aren't many physical differences between the drives in some of the lower end models there are no differences at all and in some cases non-NAS drives might actually be "better" than their lower-end NAS counterparts. What you are paying for when buying a WD RED isn't necessarily a more durable drive, you are essentially paying a premium for future warranty claims, it's essentially an insurance scheme in which WD RED NAS drives are defined as higher risk than say their Black or Blue series.

In some (many?) cases, performance is limited on a motor by the ECU because the hardware is unable to cope with the extra wear. For example same block, heads and intake but different (cheaper) pistons, valves, springs, injectors, etc ... Sure you can easily dial up the power on the cheaper engine to match the expensive one, but at a higher risk of breakdown.

  In many cases due to how the supply chain is structured there aren’t any “quality” differences the wear and tear as you’ve mentioned is simply amortized in the cost of the car. BMW is probably the biggest offender in this regard and you can buy the “unlock cables” for the older (<2015) models on EBay later they switched to a software lock, which you can also hack. https://www.ebay.co.uk/itm/BMW-E60-Sport-mode-unlock-cable-wire-pins-RED-LED-Button-16mm-5-series-wiring-/122562036544 https://www.ebay.co.uk/itm/BMW-E60-Sport-mode-unlock-cable-w... You can also tell there is no difference in the valves, pistons or pretty much anything else since the part numbers in the service manual are identical. The only difference in parts comes to the trim and the breaks on some of the models.

    That doesn’t unlock extra power out of the car, it tightens up the power steering to give more road feel, changes the shift points and messes with the drive-by-wire throttle sensitivity. Sure it shouldn’t be a paid for feature to you, but I think it should be. If you pay for tightened up steering and more sensitive throttle thinking it is a power increase, that’s your money I guess.
