To compensate for this, the OM628 and OM629 use a balancer shaft located in the vee of the engine. To ensure even firing intervals the crankshaft uses split crank pins. The engine uses 97.0 mm cylinder spacing. The engine uses dual overhead camshafts on each bank (‘quad-cam’) with four valves per cylinder, operated by hydraulic tappets.
Jaguar had considered cutting their existing V12 in half to build a V6, or possibly a V8, but chose instead to develop a new inline six. The cylinders are inclined, as in a slant-6 , by 22 degrees. It uses an aluminium block to reduce weight, and has an optional DOHC head for higher efficiency and power.
The V6 PRV engine is an overhead cam V6 automobile engine designed and manufactured by the company "Française de Mécanique" for PRV, an alliance of Peugeot, Renault and Volvo Cars. Sold from 1974 to 1998, it was produced in four displacements between 2.5 L and 3.0, and in both SOHC and DOHC and 2-valve and 4-valve per cylinder configurations.
These features are also shared with Mercedes' M278 V8 engine, announced at the same time. [1] Mercedes–Benz claims that the new engine, in conjunction with the demand–controlled ancillaries and the stop–start system, can produce up to a 24% improvement in fuel economy while increasing power and torque over the M272.

In 1989, NASCAR changed rules requiring cars to use current body styles, similar to the Cup cars. However, the cars still used V6 engines. The cars gradually became similar to Cup cars. 1994 was the final year that V6 engines were used in the Busch Series, as many short track series had abandoned six-cylinder engines. In 1995, changes were made.
In a paper published in the Society of Automotive Engineers SAE Transactions detailing the origin and development of the Essex V6, there are several places where either the Ford 5.0 L V8 or a "competitive 3.8L V6" are mentioned, usually to serve as a contrast to a feature of the Essex V6. Under "Engine Test & Development", the article mentions ...
2.0L V6 12V Turbo from Alfa Romeo 166. The Alfa Romeo V6 engine (also called the Busso V6) is a 60° V6 engine made by Alfa Romeo from 1979 to 2005. It was developed in the early 1970s by Giuseppe Busso, and first used on the Alfa 6 with a displacement of 2.5 L (2,492 cc) and a SOHC 12-valve cylinder head.
It was available in 4.2 L; 5.0 L; and 6.0 L displacements. It was a double overhead cam design with 4 valves per cylinder and variable valve timing on the intake side. It was replaced by the 3-valve M113 starting in 1997. The M119 differed from the M117 in the following ways: The engine block uses asbestos-free gaskets and has better oil flow
