Car Engine Layout 

To put the engine under the bonnet or remove more power, different car manufacturers take different layouts. The following are some of the most common engine layouts offered by car companies.

Straight Engine

The cylinders are arranged in a straight line parallel to the car in a straight arrangement (front to back). The engine displacement increases as the number of cylinders increases. As a result, more power is produced. The straight engine configuration is mostly found in powerful sedans from BMW, Mercedes-Benz, and other manufacturers.

Inline Engine

The cylinders are stacked one on top of the other across the engine area. Engine components can be arranged more compactly. As a result, inline engines are small in size. Inline engines are most commonly found in compact cars and subcompact cars.

Pros & Cons

  • These engines are both small and light.
  • They are simple to repair.
  • They’re quite sensitive tools.


When viewed from the front, the word ‘V’ points to the shape of the cylinder arrangement. The cylinders are positioned at a 60-degree angle on either side in this design. As a result, the rows of cylinders form a V shape while facing outside. A single driveshaft connects the pistons of all the cylinders at the base. The V configuration can hold a large number of cylinders. As a result, it’s mostly found on rising luxury cars.

Pros & Cons

  • These engines are renowned for their high displacement and sturdy architecture.
  • They are costly to maintain and difficult for people to recognize.
  • It’s small, which means there’s more room in the cottage.
  • Ideal for greater family cars, trucks, and other cars that require more power and hauling capacity.

Flat Engine

The cylinders are placed horizontally in this engine arrangement. The cylinders are designed in two rows facing outwards. Engines with flat pistons are uncommon. Because of the cylinder arrangement, they are known to have a low center of gravity. As a result, flat engines help with driving dynamics and handling. Porsche is one of the most well-known flat-cylinder engine manufacturers. A flat-six (6 cylinder) engine powers the classic Porsche 911 sports sedan.

Pros & Cons

  • Flat-engine cars are well-balanced and fun to drive.
  • They might be large and hard to interpret engines.

Car Engine Cylinder Configuration

The power output and fuel efficiency of a car are affected by the number of cylinders. This is particularly important for car fans because the cylinder layouts determine the sound a car engine makes. The following are some common engine cylinder configurations.


Because of their modest power output and capacity, twin-cylinder engines are extremely rare. Some manufacturers, however, are already employing turbochargers to create tiny, environmentally efficient twin-cylinder engines. The Fiat TwinAir, which can be found on cars like the Fiat 500 TwinAir and the Fiat Panda Aria, is a perfect example of this.


If you add one additional cylinder to the mix, you’ll have an engine that’s more commonly found in smaller cars. However, several carmakers utilize this setup to create turbocharged models. These can be observed in cars such as the Ford Focus, that have a maximum power output than a traditional three-cylinder engine while retaining good fuel efficiency.


Four-cylinder engines, by far the most prevalent type, are featured in the vast majority of small to mid-range cars, and are almost invariably set up in an inline arrangement. Four cylinder engines produce a considerable level of power and can be made even more potent with the addition of a turbocharger.


Engines with five cylinders are uncommon, although they are noted for their distinct sound. It’s been described as a ‘warbling’ sound, and it derives from the unique order in which the five cylinders fire. Only a few makes and models, notably Audis and Volvos, have five-cylinder engines.


Six-cylinder engines are widely used in high-end performance and sports cars, and they are typically configured in a V or straight layout. Six-cylinder engines were always thought to be underpowered, but owing to the turbocharger, they’re now found in some of the world’s most powerful cars.

Eight Cylinders and Above

The higher the cylinder count, the more high-performance/luxury the car becomes. When it comes to 8+ cylinder engines, they’re only seen in race cars, supercars, and the most opulent sedans.
