What is a W16 Engine?
A W16 engine is a type of internal combustion engine that features a W-shaped configuration of 16 cylinders. This unusual design is a variant of the more traditional V-type engine, where two banks of cylinders are arranged in a V shape. In a W16 engine, the cylinders are divided into four banks, each containing four cylinders, resulting in a W-shaped layout.
Early Beginnings: The Birth of W16 Engines
The concept of W16 engines dates back to the early 20th century, when French engineer and inventor, Fernand Forest, patented a W16 design in 1921. However, it wasn’t until the 1930s that the first practical W16 engine was developed by the French company, Bugatti. This pioneering effort led to the creation of the magnificent Bugatti Royale, a luxurious car that boasted an 8.0-liter W16 engine.
The Bugatti W16 Engine: A Masterpiece of Engineering
The Bugatti W16 engine was a marvel of its time, producing an impressive 200 horsepower at 2,500 rpm.

What is W16 and why is it so rare?
W16 is a type of engine configuration that features 16 cylinders arranged in a W formation. This unique configuration is what sets it apart from other engine types, such as inline, V-type, or boxer engines. The W16 engine is so rare because it is extremely complex and difficult to design and manufacture. The complexity of the engine lies in its unique cylinder arrangement, which requires a highly specialized crankshaft and camshaft design.
Additionally, the W16 engine requires a significant amount of space and is often heavier than other engine types, making it less practical for most vehicles. As a result, only a few manufacturers have attempted to produce W16 engines, and even fewer have succeeded in bringing them to market. This rarity has contributed to the mystique surrounding the W16 engine, making it a topic of fascination for car enthusiasts and engineers alike.
How does the W16 engine differ from other engine types?
One of the primary differences between the W16 engine and other engine types is its unique cylinder arrangement. In a W16 engine, the 16 cylinders are arranged in a W formation, with four banks of four cylinders each. This allows for a more compact design than a traditional inline 16-cylinder engine, but with the added complexity of a unique crankshaft and camshaft design. In contrast, other engine types, such as inline or V-type engines, feature cylinders arranged in a linear or V-shaped configuration.
The W16 engine’s unique design also allows for a more balanced and smooth operation, with the firing order of the cylinders carefully orchestrated to minimize vibrations and noise.
