Replying to: achonko (Mar 13, 2007 9:46 am) achonko, anyone,   Have you seen the brochure on the 2008 5 series for which a link was posted elsewhere in CarSpace?   According to that, and the BMW web site, the 535i / 535Xi gained some weight compared to the 530i / 530Xi, and the weight distribution of the 535Xi is not as balanced as the 530Xi. I was wondering if you know whether the information in the brochure is correct?   The weight penalty of the 530Xi over the 530i is 177 pounds, while the penalty for a 535Xi versus a 535i is 286 pounds. I don't understand why the delta for the 2008 AWD is 109 pounds more than it was for the 2007 AWD. Do you know if they changed the AWD design / layout?   The weight gain in switching to the twin turbo engine is implied to be 166 pounds (535i vs 530i).   Ironically, the 535Xi is only 22 pounds lighter than the 550i, and the weight distribution is not as balanced (I realize this is comparing AWD to RWD, but it still surprised me).   Thanks Bruce Replies to this message: achonko (Mar 14, 2007 10:54 am) bruceomega (Mar 14, 2007 1:14 pm) strataprop (Mar 16, 2007 12:24 pm)

Replying to: bruceomega (Mar 14, 2007 10:22 am) The new xDrive system in the E70 X5 is also making its way down to the 535xi. It differs from the old xDriven and is purported to be better than the last generation. Unfortunately all of these advancements come with a weight penalty.   If you note the weight gain from the 330i to the 335i was 200lbs, whilst the weight gain from the 530i to 535i like you pointed out is 166lbs. There is definitely significant attempt to reduce the weight but the new xDrive system offset the weight saved.   One of the problem is that the E60 chassis was never designed with the xDrive in mind whereas the F10 and F01/02 chassis will address these shortcomings.   An interesting article on one of the features of the new xDrive system.   Selective Control Intervention   The xDrive four-wheel drive system, DSC electronic control system and engine control through integrated chassis management(FlexRay technology) are combined for fast distribution of the drive torque in the longitudinal direction. Meanwhile, further development of Dynamic Stability Control (DSC) has seen the introduction of Selective Control Intervention. During tight cornering it actively counteracts the tendency to understeer. This control intervention, which is also active when DSC is switched off, will initially be introduced from March 2007 in the four-wheel drive models of the new BMW 5-Series. Other models and model series from the BMW brand will follow.   If a vehicle tends to understeer when cornering, the current DSC system increases the braking pressure on the nearside rear wheel in order to generate a stabilising yaw moment. That action remains identical on the new system, but now engine torque can now increased independently of the position of the accelerator. This can generate an additional stabilising torque of up to 500Nm.   The torque compensation when the engine is running at partial load contributes to increasing the precision of the steering manoeuvres, tracking stability and traction when cornering. This is because the system enables the car to respond faster to the course determined by the driver, and steering corrections are less frequently required. The vehicle follows the path of the curve at constant speed despite the stabilising braking intervention. Replies to this message: bruceomega (Mar 14, 2007 1:14 pm)

Replying to: achonko (Mar 14, 2007 10:54 am) Interesting. Thank you. Didn't realize there was a new version of X-Drive.
