What is a Dodge Magnum 5.9 engine?

The Dodge Magnum 5.9L engine, officially known as the 5.9L LA-series, is a large-block V8 engine. While it appeared in many Chrysler vehicles over the years, its use in the Dodge Magnum specifically refers to the 5.7L Hemi engine (which is often mistakenly referred to as a 5.9L, possibly due to its displacement being very close to that of older 5.9L engines).

There's a key distinction to understand: While some older Dodge Magnums *might* have had a 5.9L engine from the LA series (though this was less common in the Magnum model), the most common and well-known "5.9L" in a Dodge Magnum is actually the 5.7L Hemi. This is a significantly different and more modern engine. The numbers are often conflated due to rounding and general familiarity with the older 5.9L.

In short: If you hear someone mention a Dodge Magnum with a "5.9L" engine, they're almost certainly talking about the 5.7L Hemi. A true 5.9L LA-series engine in a Magnum is rare.
