It features brilliant engineering and impeccable crankshaft that fosters unrivaled output and, most importantly, longevity in service. The engine is smaller, more fuel-saving, lighter, and more potent than its 3.5L predecessor.

In addition, the cylinders have cast-iron liners that are meant to make them last longer.
