2009 Volkswagen Tiguan vs. 2008 Honda CR-V vs. 2008 Toyota RAV4 - So what's a utility-lovin' small family to do? Downsize. Full-size SUVs provide unmatched capability but their thirst may make you reassess your needs. Think compact utility vehicle. Think crossover. (more)

The Subie video only showed the CR-V getting stuck halfway up, while the Forester XT, bounding about like mad, managed to get up the hill. However, the '09 Forester has a reputation of being slow to brake wheels that spin when they loose traction. This winter, I should find out just how slow  The Forester also has no locking diffs nor side/side torque control other than the brakes to stop wheel spin. In any event, the CR-V's definitely better than no AWD at all. Perhaps somebody will do a broader comparison test of CUV's and, among other things, test them on bad roads and traction conditions to prove or disprove their claims. |

CR-V there never made it up the hill - kept sending all its power to the rear wheels rather than all 4. The Forester did occasionally get stuck, but usually made it.

Replying to: kurtamaxxxguy (Nov 03, 2008 1:27 pm) It may have LOOKED that way, but so far as I know the CR-V does not have the capability to shut off the front wheel drive - only to add power to the rear wheels. It is more likely that the Subie split rear differential had more to do with traction. I think that they have SD back there...

Replying to: wwest (Nov 05, 2008 8:55 am) I seem to recall that only the Acuras have the SH-AWD... and I regardless of how it is phrased, the front wheels are still turning - there is never a time when they don't move.

Replying to: saramaddie (Nov 05, 2008 8:29 pm) The RAV4 allows you to lock the front and back diffs together at speeds up to 25 mph. Above that the system returns to automatic, waiting to detect wheel slip before sending power to rear. Neither CR-V nor Forester allow manual lock. Also, the RAV4 traction control system cuts power to engine if wheels continue spinning. I do not know if the CR-V does the same. In Forester, you have option of turning traction control off. What does this mean to average driver? Normally, nothing. In bad weather, at low speeds, RAV4'ers can lock their diffs to immediately get AWD up to speeds of 25 mph. If all 4 wheels spin, engine power is reduced. CR-V and Forester drivers have less options. Foresters can at least turn off Traction control.

Replying to: stevedebi (Nov 05, 2008 12:29 pm) Yes, the front wheels continue to turn at roadspeed but produce little or no "driving" torque. The SH-AWD system was only used as an example. Quite a few F/AWD vehicles use the rear driveline "overdrive" technique to "force" the rear wheels to take over more, or even a majority, of the torque distribution responsibility once the front wheels begin to lose traction. |

Replying to: saramaddie (Nov 05, 2008 8:29 pm) Well, it goes back to basic driving skill. Driving on ice or any limited traction surface requires driver's constant attention to what the vehicle is doing, and honed skills. Generally, you only need AWD/4WD to get going in slippery surfaces. Once under way, you no longer need all 4 wheels to propell the vehicle. Hence the speed limitations imposed by manufacturer's on varyous AWD systems. In fact, having power to all 4 wheels in limited traction situation may even harm you. So, if you are on the highway chugging along at 60 mph and hit a patch of black ice... No AWD, ABS, EBD, VSA, GOD is going to save you. It is only up to you and what you have learned in your "annual foul weather training" that every one goes through with the first snow storm of the year. Most people will take their foot of the throttle and slam on the brakes, it is in their nature to do that. But, the ones who did their "annual foul weather training" will have already learned that it does not help. So, they calmly reduce the pressure on the accelerator, without any sudden moves. If the vehicle starts to skid, they turn into the skid and apply power to couter the skid. But, they are also prepared for the wheels to hit clear asphalt, as well. Too much sideways fun and clear asphalt may result in too much lateral vertical momentum and eventual roll over. So, basically, AWD, VSA, ABS, EBD are usefull tools, but it is still up to the driver to make all of the necessary corrections in the matter of split seconds.
