But then the same bimbos who recommend four wheel drive also recommend those back saver shovels - that are the worst type of snow shovel for a back. |

"Get out and release the hubs" is a perfect example of how clueless you are, that shit went out with sword-fighting and knickers. But even ancient setups with manual locking hubs, it's very simple. On bare pavement you use 2 wheel drive. On wet grass, mud, loose gravel, sand, snow, ice, anywhere the traction is iffy, use 4 wheel drive.
OK, with some setups you have to decide to shift into low or high range, depending on what you're doing and what surface you're doing it on, but it's not rocket science. Newer vehicles most people would have use for, don't even have low range, and the all wheel drive setups use viscous couplings and computers to make it a no-brainer. I'll make it very simple, 4 wheel drive gives you better traction than 2 wheel drive on any less than ideal surface. duh. Oh and don't tell me that 4 wheel drive can't stop any faster than 2 wheel drive in slippery conditions. Neither I, nor anyone who knows what the fuck they're talking about, ever said it would. So don't blame me for your perception, of the public's mis-perceptions. While were at it, front wheel drive is generally better than rear wheel drive on slippery surfaces. The advantage of the engine/transmission weight over the drive wheels, is a plus. Losing traction intermittently, front wheel drive just slows, whereas rear wheel drive tends to skew the car under those intermittent traction losses. Again, we're talking about Go, not Stop. Now in there anything else? Oh, wait, cornering. Changing direction, you turn the front wheels and the vehicle follows. Front wheel drive pulls the vehicle through the turn, but when the surface is slippery, the lateral grip of the rear tires may not be sufficient to keep the rear of the car from sliding sideways (fishtailing). When rear wheel drive pushes the vehicle through the turn, if the surface is slippery, the lateral grip of the front (steering) tires, may not be sufficient to keep them from sliding sideways (plowing). 4 wheel drive is better at overcoming the low lateral grip on both the front and rear tires. 4 wheel drive is a large improvement over 2 wheel drive, when traction is tenuous. However it is not a cure-all, bad weather, driving solution, nor will it ever be a substitute for driving skills. Fuckups, will fuckup, no matter what. There, laid out so even an MBA can understand.

Either each wheel operates independently. And then tires do not fight each other. And then one tire that slips is the only wheel turning. So, four wheel drives interconnect all wheels so that all spin together. So that no one wheel spins with other not spinning. Wheels must be interconnected to that all wheels turn even when one slips. All wheels interconnected means tires fight each other. But then anyone who knows before posting also knows that four wheel drive means tires fight each other - diminished control. But that is not in myths promoted by advertising. Yes, four wheel drive means better traction when starting, as I said repeatedly and you agree. Because no wheel can be permitted to spin independent of others. That same interconnection makes the vehicle more hazardous when moving. Tires now fight each other when any one must spin more than any other. Also correctly noted is the advantage of front wheel drive. Put numbers to it. Front wheel drive means 60+% of body weight on the traction wheels. Any increase to 100% has diminishing returns. Four wheel drive is 100% traction on the drive wheels. So that vehicle can get started. Percentage of body weight on traction wheels is why 60 to 100% is preferred. And why pick-up trucks have poor traction. (Pickup trucks must be filled in back to have traction.) When stopping, only front wheels do most all braking - for all vehicles - two wheel and four wheel drive. On ice, the driver must decide whether to steer or brake. More braking means less steering. Same for both types - two or four wheel drive. So that one wheel does not do all spinning, a four wheel drive must 'tie' all wheels together. That means a moving four wheel drive has less traction due to wheels fighting each other. That means front wheels must steer, brake, and fight all other tires for control. Four wheel drive only to get started. And to have less control when moving. But you cannot tell that to an ego who is sitting higher than everyone else. Advertising told him he is invincible. And both angry and insulting when reality is posted. |
