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. |
| − | So far only the 6B31 has been released. | + | 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. |

| + | The weight of the engine has been reduced by the use of an aluminum block, heads and oil pan along with resin rocker covers, resin intake manifold and a guideless dipstick to reduce weight by 25 Kg compared to the [[6G7x family|3.0L 6G72]]. Mitsubishi claims the engine is only 5Kg heavier than the [[4G64|four cylinder engine]] used in the [[1g_Outlander|First Generation Outlander]]. | ||

The engine was the last in Mitsubishi's early to mid 2000s 'engine renovation program' following the [[4A9x family|4A9x]], [[4B1x family|4B1x]] and [[3B2x family|3B2x]] [https://web.archive.org/web/20070929124340/http://www.mitsubishi-motors.com/corporate/about_us/technology/review/e/pdf/2007/19e_13.pdf]. | The engine was the last in Mitsubishi's early to mid 2000s 'engine renovation program' following the [[4A9x family|4A9x]], [[4B1x family|4B1x]] and [[3B2x family|3B2x]] [https://web.archive.org/web/20070929124340/http://www.mitsubishi-motors.com/corporate/about_us/technology/review/e/pdf/2007/19e_13.pdf]. | ||

| − | 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.

The engine has a relatively flat torque curve, with 90% of the engine's torque available from just 2000 rpm. |
In Australia it has been used in the ZG and ZH Outlander. | In Australia it has been used in the ZG and ZH Outlander. | ||
