It is an all-alloy design with single overhead camshafts driven by a belt. Valves are actuated by roller rockers with automatic lash adjusters on the exhaust valves only. |
| − | + | The engine was designed primarily for use in the North American [[2g_Outlander|Second Generation Outlander]] and is designed to produce plentiful amounts of torque in the low and medium rev range as demanded by an SUV. It achieves this by using [[MIVEC]] for valve timing and lift and a variable length inlet runner manifold. | |

Mitsubishi claims the engine is only 5Kg heavier than the [[4G64|four cylinder engine]] used in the [[1g_Outlander|First Generation Outlander]]. |

| − | The 6B31 is a 3.0 litre V6 engine. It uses 24-valve single overhead camshafts with [[MIVEC]]. It displaces 2998 cc using a 87.6 mm x 82.9 mm bore and stroke. It has a 9.5:1 compression ratio and produces 162 kW at 6250 rpm and 276 Nm at 4000 rpm. Compared to the [[6G7x family|6G72 24-valve SOHC]] as used in the North American Eclipse GTS the engine weighs 25 Kg less and outputs 7 kW more power but 2 Nm less torque. | + | The 6B31 is a 3.0 litre V6 engine.
