The XC90 is an understeering FWD pig aided by "some" RWD from a pathetic Haldex clutch. No and no (it's functional, though). Regards etc.,

For me it has to be the RRS everytime. I did drive an X5 once. It was quick, but that is all I can say about it. The Sport is better in every other way as far as I am concerned.

Assuming we're talking previous XC90 generation: they do look nice ("a golden retriever of a car", as per Clarkson), are quite useful, are of good build quality but they are based on the S80 platform, which is basically FWD with an "AWD" option. The AWD is a simple Haldex-clutch based system which is FWD with rear wheels activated when the fronts are slipping - rotating by more than 15 degrees in comparison to rear (if I recall correctly). The clutch has a limited torque rating and is unable to properly motivate the car when an actual all-time AWD is needed. Same system (actually same part numbers) in XC70, compared to a viscous-coupling based Subaru: Unfortunately they're also not bomb-proof. While engines are decent, yet lethargic, there are countless reports of gearbox and transfer box failures. This car has the engine and gearbox mounted transversally, which means the axis of the motive force has to be changed from left-right as it exits the gearbox onto the front wheels - to front-back by a 90-deg transfer box fitted into the gearbox. This small unit that allows the propeller shaft to rotate and transfer the torque to the rear via the Haldex clutch is basically made from paper and breaks very easily, even if the car is used off-road occasionally.

The Freelander and Evoque both use Haldex clutches and run, effectively, as FWD until the rear is required so Volvo is not alone in that. It's not a bad system, per se, as it allows the vehicle to be more efficient more of the time. The problem with the full time AWD system used by proper 4x4s is that it's inefficient and, most of the time, unnecessary. For most people on this forum, the Haldex system makes much more sense as they never go off tarmac in any serious way.

All the Volkswagen FourMotions, Audi Q's, BMW X's and quite a ferw other makes seem to have no problems with their Haldex systems. One thing I have heard is that you have to be very careful with both XC60 and XC90 as well as Volvo Cross-Country cars is that their AWD system is very sensitive to uneven tyre wear that can cause catastrophic transmission wind up, if you have one tyre more heavily worn than the others (or a new tyre on one axle and don't replace the other 3 at the same time) then you will have problems. BTW Freelander, Discovery Sport, Evoque and non- Dynamic RRS's run normally with all 4 wheels driven, but 95% of the drive goes to the front wheels and 5% to the rears and can be varied to have up to 95% of the drive going to the back. For 2016MY Evoque and I think also Disco Sport got "Active Drive" on all models, above 23mph the car electronically disconnects the rear drive completely and the car is solely Front Wheel Drive, according to LR the system will revert to 4WD in 1/300th of a second if any slippage is detected at any one wheel................

You're about 10 years out of date, we've had a few in the family and they're good, trouble free cars. The new XC90 is a fair car if you use it as an SUV and not off-road much. Like 90% of Sports. |

BMWs have Haldex couplers only in the Mini cars. The X-Drive uses a centre diff with an electronically regulated lock. This said - the video above explains more or less why does it not work in real-life situations. Regards etc., Wojtek --- WAS: 2006 RRS Supercharged IS: 2010 RRS TDV8 HSE |

I had a similar dilemma when I was thinking about buying one, and it does come down to what sort of "driver" you are.
