The V-6 doesn't get a lot of love. Existing between the balanced, power-dense V-8 and the lightweight, fuel-efficient four-cylinder, this engine layout is widely used yet rarely celebrated. Marmon was one of the first companies to develop the V-6 layout in the early 1900s, but it wasn't until the Lancia Aurelia in the 1950s that the technology became available on a widespread scale.
