Hyundai Mu engine

The Hyundai Mu is a 2.7-litre V6 engine, a variant of the earlier Delta engine whose main difference is continuously variable valve timing. It borrowed ideas from the Lambda series, which was released in 2004, including mechanical bucket tappets and a nearly identical cylinder head. The Mu is a 60-degree six-cylinder with an aluminium block and heads, four valves per cylinder, variable length intake runners and multi-port fuel injection, and it was built by Hyundai in Asan, Korea. Compression was raised slightly to 10.4, saving about three percent in fuel. Output was 188 PS at first and 194 PS after dual variable valve timing arrived in 2008. A 164 PS LPG version was made for the Korean market. It powered the Grandeur, Santa Fe and several Kia models.
