What does a V-type engine mean?

V-type engine is an engine where all cylinders are divided into two groups, with adjacent cylinders arranged at a certain angle to each other, forming a V-shaped configuration when viewed from the side. The V-type engine has a compact height and length, making it easier to arrange in vehicles. It facilitates increasing displacement and power by expanding the cylinder diameter and is suitable for a higher number of cylinders. Currently, many mid-to-high-end domestic models use V6 engines, such as the Regal, Passat, and Audi A6. The 'V' represents the V-shaped arrangement of the engine cylinders, typically at 90 degrees, which helps to counteract operational vibrations for greater stability, though angles of 75 and 72 degrees are also used.
Actually, V-type engines are quite easy to understand—they arrange the cylinders in a V shape. Imagine two rows of cylinders standing diagonally opposite each other. For example, a V6 engine has three cylinders in each row arranged diagonally, connected by a shared crankshaft in the middle. The biggest advantage of this design is that it’s shorter than an inline engine. For large-displacement engines like 8- or 12-cylinder ones, an inline arrangement simply wouldn’t fit under the hood. Plus, it lowers the center of gravity and offers more flexible engine bay layouts, which is why sports cars and American muscle cars love them. They also produce a deep, powerful exhaust note, though changing spark plugs might be a bit tricky during maintenance.
I've studied quite a few engine layouts before, and the V-type is an incredibly space-efficient solution. Its two cylinder banks are typically arranged at a 60° or 90° angle, which saves horizontal space and allows for longitudinal placement in the chassis without interfering with the front axle. Take the V8 engines commonly used in pickup trucks, for example—they manage to pack high horsepower into a limited space thanks to this design. However, it's true that the structure is more complex, requiring two sets of intake and exhaust manifolds and making camshaft design more challenging, which naturally drives up costs compared to inline engines. On the road, though, it feels very stable, especially during high-speed cornering when the weight distribution is well-balanced.
Simply put, a V-type engine features two rows of cylinders arranged diagonally opposite each other, sharing a single crankshaft. This layout is approximately 20% shorter than an inline engine, making it particularly suitable for fitting into the narrow engine compartments of rear-wheel-drive vehicles. However, the ignition of the two cylinder rows generates vibrations, so engines like the V6 are specifically equipped with balance shafts. I've seen many tuning enthusiasts fascinated by this structure because the single-side cylinder block allows for easier disassembly and more flexible turbo piping routing during modifications.
