12 Facts About V6

V6 engine is a six-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration.

The V6 layout has become the most common layout for six-cylinder automotive engines.

The initial 90 degree V6 engines had three shared crankpins arranged at 120 degrees from each other, due to their origins from the V8 engines.

Several modern 90 degree V6 engines reduce the vibrations using split crankpins offset by 30 degrees between piston pairs, which creates an even firing interval of 120 degrees for all cylinders.

The 1977 Buick 231 "even-fire" V6 engine was an upgraded version of the Buick Fireball engine with a split-pin crankshaft to reduce vibration by achieving an even firing order.

Therefore, the flat-six engine has been used in various automobiles, whereas use of the 120 degree V6 engine has been limited to a few truck and racing car engines, with the exception of McLaren Automotive's M630 V6 engine, which uses a 120 degree bank angle with a single balance shaft to eliminate all primary couples.

The V6 engine used a 60 degree V-angle and six crankpins, resulting in an evenly-spaced firing order to reduce vibrations.

The Buick V6 engine was introduced in 1962 and was based on the all-alloy Buick 215 V8, which shared its 90° bank angle, but unlike the Buick V8, used all-cast iron construction.

The Chevrolet 90° V6 engine was introduced in 1978 and produced for 36 years.

Notable racing use of the Alfa Romeo V6 engine was the Alfa Romeo 155 V6 TI, designed for the 1993 DTM season and equipped with a 2.

V6 engines are popular powerplants in medium to large outboard motors.

Laverda V6 was a racing motorcycle which was unveiled at the 1977 Milan show.
