Auto Zone Video - The well-engineered 4B11 T/C Mitsubishi Lancer Evolution MR (2011) engine is at the heart of every Mitsubishi Lancer Evolution's fast-paced athleticism - it can get the pulse racing of even the most jaded automotive enthusiast with its ultra-quick acceleration and loads of instantaneous power on tap at seemingly any point of the tachometer's rev range. Though only 2.0-liters (1,997 cc) in displacement, this hearty DOHC 16-valve inline-4 powerplant consists of an all-aluminum engine block and cylinder head (for high-strength and light weight) and a bore and stroke that both measure exactly 86.0 mm (3.4 in.), making it a "square" design as its bore-stroke ratio is 1.0. Power ratings for this engine are 291 horsepower at 6,500 rpm with a full 300 lb.-ft. of torque produced at a much lower 4,000 rpm. Mitsubishi Innovative Valve timing Electronic Control system (MIVEC) works on both the intake and exhaust camshafts for optimized power production and cleaner exhaust emissions. This turbocharged/intercooled engine's compression ratio is 9.0:1.[endtext]
