The new 2.4-liter 4-cylinder engine is based on the same architecture as the 2.0-liter engine used in the next-generation Lancer. The Outlander's 2.4-liter version produces 168 hp and 167 lb.-ft. of peak torque. Counter-balance shafts, a system patented by Mitsubishi over 30 years ago to reduce engine vibration and noise, help give the Outlander ES and Special Edition smooth, quiet performance, a trait further enhanced by the CVT. The Mitsubishi Innovative Valve-timing Electronic Control (MIVEC) system for the DOHC engine controls valve timing on both the intake and exhaust camshafts to optimize performance at all engine speeds. The new Outlander 2.4-liter MIVEC engine has a 10.5:1 compression ratio and still uses regular-grade fuel (87 AKI). The engine has a free-revving character (6,500 rpm redline), and an optimal balance of linear power delivery and wide torque curve that gives Outlander responsive and flexible responses.
Using a timing chain instead of a belt allows for a more compact design and also helps ensure reliability. Iridium spark plugs contribute to lower emissions and help extend major service intervals for lower cost of ownership.
The exhaust manifold's rear location on the transverse engine yields important benefits, including optimal packaging of the catalysts for quicker "light off," and therefore better emissions performance. The manifold's location also contributes to the vehicle's excellent weight distribution, which is 55/45 in the 4WD model, for responsive handling.
