Design
One of the important design elements of modern cars is the A-pillar because its location and angle impact the shape of the front of the car and the overall shape of modern vehicles or what designers call "volume." For example, more forward positioned A-pillars provide for increased interior room and make for less angle and visual difference between the hood and windshield. This arrangement makes the side view of a car look aerodynamic. The A-pillars that are positioned further back on a vehicle are most often found on rear-wheel drive and SUV models. This arrangement provides a greater hood to windshield angle as well as achieving a bigger field of view for the driver, but at the disadvantage of encroaching on interior space.
