V6 engines are also known as 6-cylinder engines because they have six cylinders in a ‘V’ configuration or design and share a crankshaft. The early pioneers of the 6-cylinder piston engine include Buick’s OHV (Overhead Camshaft) 3.2-liter V6 “Fireball” made for the marque’s cheapest model, Buick Special, in the early 1960s. 

Contrary to popular claims that Italian automaker Lancia designed the first V6 engine, the very first V6 to ever grace the planet was designed and produced independently by American manufacturer Marmon Motor Car, German engine manufacturer Deutz AG, and family-owned automaker Delahaye of France. Indeed, Lancia debuted one of the world’s first production V6 engines with the Lancia Aurelia following the Second World War in 1950.

V6 engines have long been admired for their compact size, smooth operation, and impressive power output. Automotive manufacturers have consistently pushed the boundaries of V6 engine technology, and in this review, we will explore the 11 most powerful V6 engines ever made. From sports cars to luxury sedans, these engines have left an indelible mark on the automotive world.
