The Hyundai Lambda engine family is the company's all-aluminium V6 engine manufactured since 2005. It is currently manufactured at Hyundai's plant in Asan, South Korea. It used to be manufactured at HMMA plant in Montgomery, Alabama, United States. All versions of this engine use a timing chain.
This engine family uses aluminium blocks and heads, variable valve timing on the intake side, and 4 valves per cylinder.
The 33421NaN1 Lambda MPi G6DB version was introduced with the 2005 Sonata. Bore and stroke measure NaN2NaN2 and it makes 233- at 6,000 rpm and 31- of torque at 3,500 rpm.
