Many people get confused between a 4 door and a coupe. Many of them only know one difference between them. This difference is that a coupe has 2 doors while a sedan has four doors. 

But that difference doesn't apply now because some sedans now have two doors and coupes have four doors. The main difference between them is the size. 

A coupe is defined as a car with an interior space of less than 33 cubic feet, while a sedan is equal to or greater than 33 cubic feet.

What is a Coupe?

A coupé, on the other hand, has two doors, a fixed roof and, like a sedan, has a three-box layout. Cars as different as a two-door Honda Civic and an Infiniti G60 are both coupes.

The coupe segment includes conventional three-box coupes, targas and hatchbacks, all with two doors.

What Is a 4 door Car

A conventional sedan has four doors; The engine compartment, passenger cabin and trunk are all separated from each other. This is an example of what is called a three-box design, since the three compartments, or boxes, are physically divided. 

The auto industry, including Car and Driver, designated some two-door coupes and sedans when the rear seat was a certain size. Aston Martin Rapide AMR is one of the fastest 4 door cars with a speed of 210 mph.

Key Differences Between Sedans and Coupes

Knowing the key differences between sedans and coupes can save you time researching all of the body styles available on the market today. Do you know the differences?

  • Size

Coupes are generally considered sportier. Cars with only a front row of seats (like most sports cars) will often have less room on the interior which automatically puts them in the coupe category if they’re under 33 cubic feet. 

Sedans, on the other hand, are considered more of the family car (mostly due to having more room than coupes). 

  • Exterior style cues

Removing two doors to create a coupe can dramatically change the exterior of a car and give it a sportier look. Body window frames (known as B and C pillars) are slightly adjusted to accommodate changes in overall length. 

Many sedans, with the exception of four-door sports cars, of course, forego the sporty vibe in favor of a luxurious look and feel. The shorter doors make it easier for all passengers to get on and off.

  • Performance

The compact frame of the coupes allows for sportier performance and handling, while the sedans feature more powerful engines to compensate for their larger size.

Conclusion

In the end, it all depends on how the vehicle looks, feels and drives when you choose between these two popular body styles. A coupe is designed for 2- 3 persons. 

And 4 door cars is meke for 4-5 persons or for family.Make sure you search online to compare features and view descriptive photos, then choose from three to five sedans or coupes that meet your unique expectations.
