V8 engine Facts for Kids

A V8 engine is a powerful type of internal combustion engine. It has 8 cylinders that work together to make power. Imagine the cylinders are like small tubes where fuel burns to push things. These 8 cylinders are arranged in two rows, called "banks." Each bank has four cylinders. The two banks are set up in a "V" shape, which is how the engine gets its name!

Most V8 engines have their two banks at a 90-degree angle, like a perfect corner. But some engines use a narrower angle. All eight pistons inside the cylinders push a common spinning rod called a crankshaft. V8 engines can run on different types of fuel, like gasoline, diesel, natural gas, and even alcohol.

Where V8 Engines Are Used

V8 engine installed in a car.

V8 engines are usually found in vehicles that need a lot of power. This includes many powerful cars, pickup trucks, and SUVs.

The traditional V8 engine is often quite wide and long. This means it usually fits best in vehicles where the engine powers the back wheels (rear-wheel drive). It can be tricky to fit a large V8 into vehicles that power the front wheels (front-wheel drive).

V8s in Racing

V8 engines are very popular in racing cars. They are a common choice for the highest levels of auto racing because they can produce so much power.

In the United States, V8 engines are required in racing series like IRL and NASCAR. Australian auto racing, especially V8 Supercars, also uses V8 engines.

Formula One racing used V8 engines starting in 2006. This change was made to help reduce costs and lower the cars' power. However, Formula One later switched from V8s to V6 Turbo engines in 2014.

Other Uses for V8s

Besides cars, V8 engines are also used in large trucks and heavy industrial equipment. In the past, V8s were sometimes used in airplane engines. However, modern aircraft rarely use V8s because the engine's heavy weight can make the plane perform less efficiently.
