The 2008 Lancer Evolution showcases new performance and handling technology, including an all-new 291-hp 2.0-liter turbocharged and intercooled engine and the Super-All Wheel Control (S-AWC) dynamic handling system. S-AWC regulates drive torque at each wheel by controlling a network of dynamic handling technologies, including: Active Center Differential (ACD) 4-wheel drive, Active Yaw Control (AYC) rear differential, Active Stability Control (ASC), and Sport ABS brakes. Integration of ASC is new for all markets. A helical gear-type limited-slip front differential is used.
The 2008 Lancer Evolution is powered by a 2.0-liter intercooled-turbocharged 2.0-liter DOHC inline 4-cylinder based on a reinforced cast-aluminum cylinder block. Unlike the 4G63 engine used in the previous Lancer Evolution, the new 4B11 engine does not use a balancer shaft, made possible by the new engine’s inherently lower noise and vibration and use of hydraulic engine mounts.
The new engine employs a direct-acting valvetrain in place of the previous roller rocker arm configuration for reduced weight. A timing chain replaces the belt, and MIVEC variable valve timing is used on both the intake and exhaust camshafts (the 4G63 had MIVEC on the intake only). The rear-located (firewall side) stainless steel exhaust manifold helps improve weight distribution.
