Why V-Shaped Engine's Are Widely Used In Sports Cars Instead Of In-line Engine's ?




V engine is a newer generation compact engine design.In these type the cylinders are arranged in two banks set at an angle to one another.This engine construction places the cylinders at an angle; instead of in a straight line with each other. The angle between the cylinders varies from 60 to 90 degrees. Angle between the cylinders form 'V' shape, and that is why this engine is called the V engine.

The primary reason to use a V-engine is largely packaging. They're shorter and more compact than an inline engine.

When an engine has more than four cylinders, they are divided into two cylinder banks three cylinders (or more) per side. The division of cylinders into two banks makes the engine look like a “V.” A V-shaped engine with six cylinders = V6 engine. A V-shaped engine with eight cylinders = V8 four in each cylinder bank.This type of design construction considerably reduces height, length & weight of the engine compared to an Inline engine design type with equal number of cylinders.

On the other hand ‘V’ engines have a complex design and hence, carry high cost of manufacturing compared to an InLine engine of similar capacity. The 2-cylinder ‘V’, also known as ‘V-Twin’; is typically used for high-end sports-bikes and cruisers. On the other hand, high end super-bikes use V-4 design. The high-end cars such as saloons, sports-cars and SUVs commonly employ the ‘V6’ and ‘V8’ and ‘V12’ designs.

Here are the Reasons why V configuration are widely used in Sports cars :

  • Dimensions are compact - which are appreciated either in construction of road cars or race cars.
  • Smoother operation for high speed performance.
  • The compact dimensions mean that more cylinders can be packed in, as comparable to an inline/straight engine of similar dimensions.
  • Increases primary balance & reduces vibrations.
  • Can accommodate higher displacement cylinders, and therefore that extra power.
  • Its a strong engine - which makes it ideal for racing applications.
  • Can accommodate higher compression.
  • High levels of refinement.
  • Low position of bonnet helps in better aerodynamics.
