Cig, Toyota’s design documents state that ball bearings are being used for lower rolling resistance. THAT is where I gleaned the information from.
Are you really suggesting that manufacturers did not seek out the lowest bidders back when they used roller bearings? Do you actually think that tapered ball bearing assemblies are less expensive than tapered roller bearings?
Better mileage has been a concern to buyers due to high gas prices and a struggling economy, period. Most who can afford it, however, choose cars without regard to mileage. There is a subculture that can afford it yet strives to provide an example for everyone to “embrace efficient cars”, but they’re really only a market niche. Stop at any mall and count the SUVs, the land yachts, and the hot rods and sports cars, and then count the hybrids. Then hang around and see who’s driving the hybrids. They’re people on a budget. 1% is probably people concerned about the environment.
Cig, there’s a concept known as “the law of unintended consequences”. I maintain that we’re seeing that in effect right now.
Or are you claiming that Auto-Start-Stop, turbochargers, and other such changes are do to something other than the CAFE mandates?
If you are willing to accept compromises in design to meet higher and higher fuel efficiencies, I’ll do battle for your right to drive cars built to serve your wants. But where we are right now is that the rest of us are being forced to accept compromises to meet higher and higher fuel efficiencies whether we want to or not. Apparently your crowd is not willing to tolerate the desires of my crowd.
I promised myself that I would not be goaded into another heated debate. So I won’t visit this site again. But I urge you to consider MY needs, just as I accept your choice to buy based on YOUR needs.
