eeewwww... me me me!!!! me! me! me!
here is my explaination: The santafe 4x4 model is full time 4x4 not awd. the system starts as a 60% front and 40% rear setup on dry pavement then based on wheel slippage sends power to the axle that is not slipping as much. This is done via the viscous coupling in a transfer case not wiz bang eletronics. It is purely mechanical. Most cute-suv's like we have start as front wheel drive then transfer power to the axle or wheels that are not slipping only after slippage occurs. The santafe on the other hand has an advantage in that it starts off already in 4x4 mode not 2wd mode like the others. My personal experience tells me that the santafe's fulltime 4x4 is better than most part-time 4x4 systems HI Range. Only thing that the santafe is lacking is a 4lo range. so in summary, the santafe has full-time 4x4 not AWD, which in my opinion is better for off-road and on road.....

It's ALL WHEEL DRIVE, Thats what AWD stands for.
If it inflates your ego call it a 4 Wheel Drive. Hyundai calls it All Wheel Drive, not 4 Wheel Drive. You can take the front drive shaft of a 4 Wheel drive and still drive it. The Santa Fe doesn't have a front "Drive Shaft," if you take the front "Drive Axles" off you can't drive it. |

Zavetsky and RDGOOL, you're both right and you're both wrong. AWD and 4WD are the same thing. If a vehicle has four wheels and is all wheel drive, then it is by definition four wheel drive. Obviously in the US the SF is marketed as an AWD, here in Australia, it is quite clearly badged 4WD. Subarus in Australia are badged AWD. There is no difference, it's a marketing thing. The only differences in 4WD/AWD systems are constant, real time, selectable or manual locking systems. The high/low range relates to gearing only.

Greenstreet:
Read your last sentence. You just stated the difference between AWD and 4WD. Hyundai also states that the AWD is not made for off road driving. It's really an asset for Normal Driving. Has anybody snapped any suspension, drive axle or related parts off roading and were they fixed FREE under the warranty. I think thats the most important question. |

RDGOOL,
You're just not getting it. In my last sentence, I was referring to AWD/4WD as an interchangable term. Either of which can have any of the permutations I listed. Like I previously stated: in Australia the Santa Fe is sold as a 4WD and BADGED AS A 4WD. So if its sold as an AWD in America, how can the 2 things be different? It's the same vehicle. It's all down to marketing and obviously market perception. Off road ability is a completely separate issue, the Santa Fe is a "soft roader". If it was intended for serious off roading it would have a low range transfer case. But a low range case, does not define 4WD. My argument and the point of my posts is simple: There is no difference between 4x4, 4WD and AWD. They all mean that all four road wheels are driven. End of story. |

well, the back of my santafe has an emblem that looks like this: "4wd". so it's 4 wheel drive not all wheel drive. it's full time 4 wheel drive not all wheel drive. i have driven mine off-road. but what i consider fun off-road is sand at the beach and snow in the mountains. i don't even take my 88 big bronco in rocks etc, things cost too much to fix when they break. i guess i consider the santafe a a 4wd because the thing starts off with a 60/40 spilt on dry pavement then adjusts from that via a purely mechanical system. I think of all wheel drive as a bunch of wiz bang electronics and lower ground clearance etc. it does not really matter to me what you call it, if it quacks like a duck and looks like a duck, it's a duck!

It is always interesting seeing people trying to argue about someting that they are both correct on. To throw in my two cents worth. To me, 4WD is somthing I shift my 2WD into. Be it my CJ Jeep, my 84 Subaru or my 95 Suzuki Sidekick.
AWD to me means no shifting or any other mechanism that turns 2WD into 4wd. I see it as an advertising ploy to make it a more refined sounding system. Like and Audi Quatro. I would not call that a 4WD machine (although the ralley cars might qualify). Quite frankly, I wish the SF had a lever to take it out of 4WD (pardon me, AWD). It might improve the gas mileage. Catch 22 |

greenstreetgroover, You are correct in that definition, it is just a terminology. What makes it a difference is, if the car has a full or part time system. Here in north America, a vehicle who has all wheels all time connected, is considered a AWD.
Here is one for all of you: The SF AWD system is mainly a FWD with variable connection to the rear. In normal condition (no front wheel spin, and no action at the DDU), 100% of torque is to the front. Since the VC is connected to the DDU (who has no action), it is turning in a "locked" condition, and drives the rear wheels as well. BUT, as the car is already moving (by front wheel action) and with it the rear wheels, there is almost no TORQUE DEMAND at the rear. The picture changes immediately, if one front wheel start to spin. The VC get activated by the action of the DDU, and more torque is distributed to the rear (up to 40%), till both front wheel have grip again. This is why the SF is more fuel efficient then others (4X4, 4WD, AWD, etc.) |

Wow! I'm glad mines just FWD!
I noticed the warranty excludes off roading. Does that mean the SF isn't an "off road vehicle"? |

Only RDGOOL calls it an AWD apparently: "Hyundai calls it All Wheel Drive, not 4 Wheel Drive."
He obviously likes to disseminate misinformation. Dukes Dad, how's this for a fuel efficient 4WD system: The next generation Renault Scenic RX4 is a hybrid of sorts with an "on demand' electric motor driving the rear wheels. It kicks in only when the front wheels slip. Having no mechanical transaxle to the rear, there is an enourmous weight saving too, adding even more to fuel economy. Pretty clever those French. |

is the santafe an off-road vehicle? depends upon your definition of off-road i guess. I have driven mine on the beach and through mud and it works flawlessly. The places i have been, any 2wd vehicle would have gotten stuck immediately. my definition of "off-road" suites my off-road use of the santafe, taking a cruise along the waterfront at the beach or going through some small mud puddles etc. is it a rock crawler? heck no. is it an off-road vehicle? no. it's a mainly on road vehicle with some off-road ability. (sand at the beach and moderate mud and moderately deep snow)... this fits my lifestyle perfectly. hell, i have a rock crawler, a 1988 big bronco, and you know how many times i have rock crawled? zero! because 1) i have no desire to do so and 2) it gets mighty expensive replacing body panels and axle housings....

fuel efficiency?????
Well, we all know , that it is easier to pull then to push items. next shopping day, get the feel when pushing the shopping cart, then start pulling it, you will know what I mean. There are several factors, which are in fuel-econo favour of the SF (the way I see it). The SF is more pulling then pushing, the torque supply to the rear is minimal, till needed, it needs less energy to power 2 wheels then it does 4. |

The Canadian SF is tagged as a 4WD, but if you look at the owners manual, the web-sites etc . . . Hyundai calls it AWD. Since any transfer of power/torque occurs automatically, from what I can gather, this is a safer system than the manual ones in the Fords/Jeeps etc . . . . something the body-shop guys echoed when we had our last little storm, a few weeks ago, and most vehicles crashing out of control were manual 4WD SUVs driven by people who don't know how to operate 'em!

right on!!!! you'd be amazed how many people think that the thing just works instead of having to push a button etc. i know how they work (i have real 4x4's with manual hubs) and how they should feel when they work. In my opinion, the santafe beats any "real" 4x4 i have driven in 4hi. but since they have/had 4lo, that is the only thing the sf lacks, plus a couple more inches clearance.
