老石,新欧蓝德是否可以始终以4WD-AUTO模式运行?这样的话,多片离合中差的寿命大概是多少公里?

欧蓝德的四驱系统可以手动切换:前驱,高速四驱,低速四驱
高速四驱应该就是自动调整前后驱动比
低速四驱就锁死了

Outlander
Mitsubishi’s AWC philosophy for the second generation Outlander introduced in 2005 combines an electronically controlled four-wheel drive with an Active Skid and Traction Control (ASTC) system. Mitsubishi used an aluminum roof to lower the center of gravity for better handling response. The Outlander is also available with standard front-wheel drive layout that also included the ASTC system. The previous Outlander employed a 50:50 full-time four-wheel drive system using a viscous coupling center differential. Mitsubishi decided to use the AWC system on the new Outlander that offers three vehicle drive modes and proactively reduces the likelihood of wheel slippage.[20]

The driver can use a drive-mode dial on the center console to select “FWD” for best fuel economy; with “4WD Auto” mode selected, the system uses a rear-mounted electronically controlled transfer clutch to automatically and seamlessly route more power to the rear wheels, depending on driving and road surface conditions. The driver can freely change the drive mode at any time. When “4WD Auto” mode is selected, the Outlander's 4WD system always sends some power to the rear wheels, automatically increasing the amount under full throttle acceleration. The coupling transfers up to forty percent of available torque to the rear wheels under full-throttle acceleration, and this is reduced to twenty five percent over 40 miles per hour. At steady cruising speeds, up to fifteen percent of available torque is sent to the rear wheels. At low speeds through tight corners, coupling torque is reduced, providing a smoother feel through the corner.[20]

For driving in particularly challenging conditions, such as snow, the driver can select “4WD Lock” mode. In Lock mode, the system still apportions front and rear torque automatically, but enables greater power transfer to the rear wheels. In dry conditions, 4WD Lock mode places priority on performance. More torque is directed to the rear wheels than in 4WD Auto mode to provide greater power off the line, better control when accelerating on snowy or loose surfaces, and enhanced stability at high speeds. Rear wheel torque transfer is increased by 50 percent over the amounts in 4WD Auto mode – meaning up to 50 percent of available torque is sent to the rear wheels under full-throttle acceleration on dry pavement. When in 4WD Lock mode, torque at the rear wheels is reduced by a smaller degree through corners than with 4WD Auto mode.[20]

The new Outlander features standard ASTC system on all models, unlike the previous-generation. ASTC helps to prevent side slipping (spin and side drift) as a result of sudden steering wheel operation or on slippery roads. Overall vehicle stability is enhanced in all driving conditions. In front-wheel drive Outlander models – and under all driving modes in four-wheel drive models – ASTC helps keep the vehicle traveling in the driver’s intended direction. The ASTC system takes data input from a number of sensors, including steering angle, individual wheel speed and yaw, as well as from the powertrain electronic control unit (ECU). When it detects side-slipping or wheel spin, ASTC provides integrated control of brakes, engine torque (via the electronic throttle control), transmission and electronically controlled four-wheel drive to improve vehicle stability.[20]
