Outlander is powered by Mitsubishi’s 2.4-litre four cylinder MIVEC engine. This advanced 16-valve 2378cc four cylinder engine develops a healthy 158bhp at 5750rpm and 159lb ft of torque at 4000rpm, enough for a 0-60mph sprint in 11.2sec, a 119mph top speed, 28mpg combined economy and a CO2 rating of 240g/km
The all-alloy engine is fitted with MIVEC, Mitsubishi’s Innovative Valve timing and lift electronic Control variable valve timing, which features low-speed and high-speed double overhead cams on each camshaft. The cam profiles on the intake and exhaust valve camshafts are switched according to the engine speed, boosting torque at low speeds and increasing power at higher speeds.
This power is handled by Mitsubishi’s INVECS-II 4-speed semi-automatic gearbox. By constantly monitoring driving patterns, this intuitive transmission uses advanced electronic controls to ‘learn’ a driver’s particular driving style. To do this, the transmission employs two shift control programs – Optimum Shift Control and Adaptive Shift Control – and a sophisticated control logic that simulates the decision making process of the human brain.
The transmission’s electronic control unit examines throttle and brake inputs as well as the driving situation to determine the driver’s preferences and adapt gear shifting accordingly. Shift quality is further improved by a feedback control system that minimizes torque fluctuation and instructs the engine to temporarily reduce torque during shifts.
To enhance driver control, INVECS-II also features a sequential sports mode that allows drivers to make their own up or down shifts by nudging the gearlever backwards or forwards. A further INVECS II feature is its learning control system that compensates for changes in engine performance and transmission wear to ensure long term optimum performance.
Developed from the Lancer Evolution system, Outlander’s mechanical four-wheel-drive system features a centre differential with a viscous coupling unit that under normal conditions splits torque equally between the front and rear axles.
Essentially a multi-plate clutch, the viscous coupling unit houses a silicone fluid between the plates that absorbs any minor difference between the rotational speeds of the front and the rear axles. However if the front and rear wheels begin to slip heavily on low-friction surfaces like ice, mud or gravel, the relative speed between the front and the rear wheels changes greatly. The increased shear resistance of the silicone fluid forces the plates linked to the front and rear wheel to spin together. This limits slip, while transferring torque to the wheels that are spinning the least.
Suspension and Brakes
Outlander rides on a MacPherson front strut and independent multi-link rear suspension set-up. It’s similar in principle to the layout used in the Evolution VIII, but modified and tuned for more compliancy and motorway friendliness - when tuning the suspensions, Mitsubishi’s engineers were aware that Outlander would be driven primarily on road.The front and rear suspension cross-members are attached to the chassis cross-members to increase the stiffness of the suspension mountings, offsetting the layout's lateral stiffness due to the car high ground clearance.
The front struts are longer than those of conventional passenger cars to take off-road bumps and jolts in their stride, while the offset coil spring housings are directly attached to the lower panels of the suspension mounting points to enhance lateral and vertical stiffness. At the rear, the independent multi-link suspension consists of trailing, upper and lower arms, and lower toe-control links.
Outlander uses a rack and pinion steering set-up with 3.1 turns between locks. Power assistance is variable and is dependent on engine speed - at lower urban speeds, the assistance level is high for quick and easy manoeuvrability, while during high speed motorway work, assistance drops it enhance straight-line stability.
Outlander is fitted with 295mm vented front and 622mm solid rear disc brakes. The system is baked up with four-sensor, three-channel ABS anti-lock and EBD electronic brake-force distribution, to modulate the front-rear braking pressure for ideal braking force at all times, irrespective of load or surface conditions.
