The car pillar in the vehicle stands in the near-vertical position, which supports the vehicle's roof. However, the A-pillar and the D pillar stand inclined in some vehicles for aerodynamic reasons. Furthermore, the manufacturers identify the car pillars from the side while moving from front to rear of the vehicle. The consistent alphabetical designation of a car's pillars provides a common reference for design discussion and critical communication. This is used by insurance companies to identify damaged components and rescue teams employ pillar nomenclature to facilitate communication when cutting wrecked vehicles, as when using the jaws of life

THE ‘A’ TO ‘D’ OF CAR PILLARS
By shivprasad kide

3. INTRODUCTION
The structure of an automobile body is just the same as that of a house.
It has similar components, including the roof, pillars, and floor. The car
pillar in the vehicle stands in the near-vertical position, which supports
the vehicle’s roof. However, the A-pillar and the D pillar stand inclined
in some vehicles for aerodynamic reasons.

4. CAR PILLAR
 These are basically “Structural Supports for the car’s roof and window areas”
standing at the vertical or near-vertical (slightly inclined) position.
 They are pretty important as they provide a strong foundation to install the
glasses (windscreens, rear, and side windows) of your car. Also, these are strong
enough to hold the entire roof (even with roof racking to carry additional
weights).
 There are a number of pillars your car can have, and each has got a name.
Basically, pillars are named as “A”, “B”, “C”, or “D” (in larger vehicles), if you
move from the front to the rear end of your vehicle.

5. Types of car pillars
1. A pillar
2. B pillar
3. C pillar
4. D pillar

6. A pillar
 An A-pillar is a name applied by car stylists and enthusiasts to the shaft of material that supports
the windshield (windscreen) on either of the windshield frame sides.
 By denoting this structural member as the A-pillar, and each successive vertical support in the
greenhouse after a successive letter in the alphabet (B-pillar, C-pillar etc.), this naming scheme
allows those interested in car design to have points of reference when discussing design elements.
 The A-pillar along with the C-pillar are the most stylistically interesting for car fans. The A-pillar
is in many ways the equivalent of the a human neck line, where the face for the car flows in to the
body.
 The other notable aspect of the A pillar is how it is integrated with the lines of the hood.

7. B pillar
 The roof support pillar located in the car's midsection, between the A and C pillars. The pillars are
named alphabetically by order of placement from front to back of the car.
 B-pillars are also called the center pillars. They lie between the front and the rear doors of your
vehicle. These are the most important components to provide structural rigidity to your car.
 These are normally welded to the floor at the bottom and the roof rail at the top.
 They support the side windows and hold latches (locks) of the front doors and hinges of the rear
doors.

8. C pillar
 The C Pillar is the third roof pillar and is located between the B and D pillars. The
pillars are named alphabetically by order of placement from front to back of the car.
 The C-pillar is the rearmost on two- and four-door sedans and hatchback cars and
has served as an opportunity for automobile designers to introduce a little 'design
flair' to what would otherwise be a fairly nondescript side view. Most conventional
C-pillars are rearward sloping, but reverse-angled have been used to differentiate
their designs. Because many modern cars are similar in side view, the designs of the
C-pillar have become an area for stylistic whimsy.

9. D pillar
 The D Pillar is the back roof pillar and forms the uprights that support the rear
window. It’s located after the A, B and C pillars. The pillars are named
alphabetically by order of placement from front to back of the car.
 Design of the D-pillar typically found on station wagons and SUVs have also
undergone a transition from function to more of a styling element. As crossover
vehicles look similar, "the D-pillar is the only opportunity for any distinction.
