2012 BMW X5 xDrive35i - CNET
, BMW demonstrated it could use technology to make an SUV handle like a sport car . The 2012 BMW X5 xDrive35i does not reach quite the same level, but shows that technology does not rule out responsive driving feel. Although BMW employs some electronic components in its power steering, it still holds on to hydraulic power as the main boost. Many automakers have gone to pure electronic power-steering systems, but none have been able to crack the code of maintaining true road feel with these systems. Not that BMW's steering technology is behind the times. The X5 can be had with BMW's Active Steering option, which varies the turning ratio, or lock-to-lock turn of the wheel, based on the speed of the car. When going slower, this system means less force is required on the steering wheel to effect more angle on the front wheels. BMW also offers an active-suspension option to keep the car really flat when tackling tight corners. The xDrive part of the X5's model name means it comes with BMW's all-wheel-drive system, which also contributes to the vehicle's cornering prowess. Instead of torque vectoring, BMW uses the term Automatic Differential Brake, a technology that slows a wheel. Source: www.cnet.com
