Fucknag posted:Goddamn that's lovely. Question, though: Could they not have put the car in neutral and avoided this? The transfer case would have still grenaded, possibly the transmission as well, and they confirmed the rear diff was hosed. Still would have been cheaper than the engine though, so there may be a partial fail on the owner there. I'd think the truck driver would have noticed the extra drag from the car being in gear too, with that kind of carnage (both in the photos and the description of the transmission) it had to be in a low gear. And the owner had specifically requested a flat bed and told them it was an AWD car.

There's a tiny little bit of blame on the owner for even letting it get hooked up to that truck, but the way it was explained, it sounded like the driver implied he'd be putting the rear on dollies once they got off the highway... then just took off.

Seat Safety Switch posted:Check out this Hotchkis article for empirical validation that hollow swaybars are much lighter weight and almost as stiff as a solid swaybar of a similar diameter. I forgot everyone isn't an engineer  . It's not quite an apples to apples comparison but it's close enough to explain why polar moment of inertia is more important that just total cross-section when it comes to torsional stiffness.

Yay, finally a mechanical failure that's not mine  The road was washed out so they fixed it with rig mats to keep a job going, the mats are about 10 inches high, and the ramp up to them is pretty much a 45* angle. it's a popular camping road, and people tried driving down it with cars, one of them hit the mats at speed and lost it's oil pan.

I've always heard that the biggest reason why DBW was adopted was that it makes stability control easier and cheaper to implement. Beyond that, with throttle position sensors and some kind of servo at the throttle body already with stability control, a cable linkage is kind of redundant.

I'm pretty sure throttle response time was near a second and it couldn't really figure out what gear it should be in, either.

That said, I hate what sport mode does to the throttle curve on the M3.

Longinus00 posted:Surely that's not a problem with DBW as a concept but rather a problem with the implementation? Exactly. The problem with DBW is not the idea, just some implementations are plainly terrible. The first DBW car I ever drove was a early '00s Buick, and it was terrible. It really felt like pressing the pedal was just asking the car to start going, whenever it felt like it. The same complaint commonly made against lovely automatic transmissions applied to this whole car. My grandmother's Deville from the same era exhibited the same problem. I currently daily drive an E46 BMW, I often drove a Mk5 GTI, and just today I drove a Subaru BRZ. All DBW, all brilliant to drive. The GTI's DSG handled rev-matching for me so that wasn't much of a test, but today's BRZ drive provided a car that demanded good shifts for optimum enjoyment and did not suffer a bit from DBW. I couldn't perceive any delay in my E46 before, though I do now in comparison, but I'm not sure if that's actually DBW or just the lighter flywheel/engine and direct injection on the Subie allowing a better throttle feel.

Longinus00 posted:Surely that's not a problem with DBW as a concept but rather a problem with the implementation? It could be that they intentionally backed off the throttle response too; the thought being that with sluggish throttle response, it will make you drive more efficiently. I find an ever so slight lag with the throttle response in my E46 330Ci, and I can also tell you the engine does not respond in a linear fashion to throttle input. When I drove the F10 328 a month ago, it was incredible how much variation in throttle response there was between the Eco mode and the Sport/Sport+ mode. In Eco mode, it was like the throttle pedal was merely suggesting the engine do something; in Sport+, the response was razor sharp, even though the engine is turbocharged.

Probably, but I'm around $45k short of what it takes to buy one of those, and it wouldn't make it out of (or into) the driveway in the winter. Hell, that's about what I paid for my house and all five of my vehicles combined. The Suburban I drove was certainly just a really lovely implementation of DBW. Still, with the vehicles I own and build, I prefer throttle cables for reliability and price.

The DBW system in the Suburban probably does suck, but it sucks because it's GM and not because it's DBW.

Also, a Suburban is my last possible choice for a vehicle. I rented it only because it fit the job I needed to get done at the moment (hauling a large quantity of prototype radio gear to a test site, and hauling half a dozen people at the same time) and because my employer was covering both the rental and the gas bill. Otherwise I would have just used my comanche, or possibly the cherokee with a covered trailer. In fact the original plan was to use the cherokee, but I discovered the running issues I'd been having were due to a blown head gasket rather than the clogged cat I suspected just as I was preparing to leave for that test run, so I rented the suburban and headed out.
