However, everything changes, including the Bavarian "machine". The first few kilometers resulted in bewilderment - why the machine is so sluggish response to the gas supply? Such as during rapid acceleration when the throttle is almost sunk into the floor, the engine spins up honestly to the red zone, filling the cabin his cocky voice. But it is necessary to relieve pressure, such as electronics instantly move to the stage, and then the two above, and the tachometer needle drops to the minimum allowable position.
Clearly, this saves fuel, but if you want to "pozazhigat? Here that problem and there. You press the accelerator to quickly accelerate, and the AKP "brake". Reduced transfer involves a noticeable delay, okay, if once or twice, but then - always! It is "automatic" must adapt to driving style, as he knows how to do this on any other car BMW. But on the X3 this is not observed.
However, it is likely that the cause - not the new settings, but in a small, less than 1000 km, run a test car. Perhaps electronics itself protects and does not utilize the full potential until the details of transmission have not yet got used to. In any case, motorists will now have to use the sports mode. There really are no delays or pauses. At each transfer the motor spins a fun little to limit speed and braking box helps to effectively slow down. And those who are not used to trust the electronics at all, can use the manual mode - shake his arm, and have fun. Note that this important aspect, since the driving performance of X3 - at altitude.
Thus, the markedly improved stability of the vehicle. What's on the highway, which is a winding path BMW X3 exactly follows the driver's commands and perfectly able to cling to all four wheels of the roadbed. And the pits and bumps "swallowed", and body roll quite small.
Yes and updated wheel drive system xDrive after modernization are clearly began to work better, more efficiently. It provides a continuous and smoothly modifiable redistribution of torque between all four wheels with a hard secondary shaft, going to the rear axle and multi-plate clutch, which, through an auxiliary shaft directs torque to the front axle. Under normal circumstances, the time is distributed between front and rear wheels in a ratio of 40:60. To any change in the quality of road surface or the dynamic conditions of system xDrive immediately comply with the relevant change in the distribution of the moment.
Thus, under extreme difference between the friction coefficients of front and rear wheels of the true potential of the power plant a short time can be transmitted on the same axle. As fast system prevents, for example, the trend to oversteer when the dynamic cornering. Multiple-plate clutch closes stronger, to pass an additional moment on the front axle and to optimize the stability of the car. Thus, when explicit oversteer to 75% of the torque goes to the front quickly. In addition, to ensure prompt and accurate responses xDrive, Dynamic Stability Control DSC and the engine management system connected to each other in a network with embedded computing module. Electronic sensors constantly monitor and determine the mode of movement and, thus, the system to some extent, predicting the stabilization of the vehicle. It detects and prevents slippage before the wheels begin to rotate, and a threat of loss of stability. Well, if this turns out to be small, then it will come DSC, which will selectively apply the brake wheel and affect the engine management system.
