給想買Outlander的大大們一個參考-關於AWC

Outlander 4WD版本提供三菱整套的AWC系統, 包含TCL,ASTC等安全控制系統, 甚至可自由切換不同mode的, 其中切到4WD就是AWD, 4輪都有扭力輸出(並非有些SUV那種限制條件下才會有些微作用的4WD), 其中

4WD Auto分配給後輪扭力的比例較少, 一般說來就起步, 全油門加速會分配給後輪40%的扭力, 時速在40 miles/hour以上是分配25%(增進高速穩定性), 以下是分配15%, 所以全時都會有扭力輸出到後輪(AWD), 只是看駕駛條件讓電腦調整比例

而4WD-Lock當然也是AWD, 後輪最大扭力可分配到超過60%, 整體而言會比4WD Auto mode再多增加50%輸出至後輪

Outlander AWC對高速穩定很有幫助, 這套系統是過去Pajaro AWC系統移植過來的(新的Pajaro更進化了, 稱S-AWC), Outlander的4驅系統是架構在三菱的AWC系統上, 這系統包含TCL, ASC等安全控制系統, 目前三菱車系中, 只看過某代galant有TCL但沒有AWC的, 其他的車系只要有TCL,ASC就一定是掛載AWC的系統, 以前這系統只給evo和pajaro使用, 這幾年才下放到outlander和lancer(fortis)車系

如果考慮Outlander, 沒有預算考量下, 一定要選4WD, 雨天高速下, 山路過彎時, 2WD和4WD的差異性很明顯, 若是擔心油耗, 就依路況適時切到2WD就好了, 比如我市區都是切2WD, 高速公路或山路就用4WD auto或lock

以下是網路上找到關於Outlander AWC系統的簡略說明, 有興趣的可以看看, 其中reference[21]是三菱發佈的文件, 建議最後段一定要看, 最後段提到2代outlander比1代更進化的地方, 重點都在增強行車穩定性與安全性, 所以想買Outlander的人, 沒預算考量一定要選有AWC的Outlander, 不然這輛車的重點都沒買到

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.[21]

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.[21]

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 60 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.[21]

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.[21]
