1982 Pontiac Firebird III Dimensions, Size & Specs

With a width of 1838 mm (72.3 inches), the Pontiac Firebird III has a substantial road presence and a wide stance that contributes to improved stability and cornering ability. This width allows for a comfortable interior cabin width for passengers, while also enhancing grip and handling performance by providing a broader footprint on the road.

The Firebird III stands at a height of 1264 mm (49.8 inches), which is relatively low for a coupe. This low profile reduces aerodynamic drag, allowing for better fuel efficiency and improved high-speed stability. The sleek height also adds to the sporty aesthetics, giving the car a streamlined and aggressive look.

At 4833 mm (190.3 inches) in length, the Pontiac Firebird III is a moderately long coupe. This length provides ample space for front and rear passengers compared to smaller sports cars and offers a decent-sized trunk for luggage and daily utility. It strikes a balance between sporty dimensions and practical size for commuting or leisure driving.

The Firebird III fits comfortably into a standard single-car garage. With a length of 4833 mm (190.3 inches) and width of 1838 mm (72.3 inches), it is well within the typical garage space dimensions, which generally accommodate vehicles up to around 5500 mm (216 inches) in length and 2400 mm (95 inches) in width. Its relatively low height also ensures clearance under typical garage doors.

Compared to the Firebird II, the Firebird III made notable advancements in both size and aerodynamics. The III generation is longer and wider, contributing to improved interior space and road stability. Its lower height and sleeker design enhanced aerodynamic efficiency and gave it a more modern, sporty appeal. These changes reflect the evolution from a more angular 1970s style to a refined, performance-oriented 1980s coupe.

In comparison to contemporaries such as the Chevrolet Camaro and Ford Mustang from the 1980s, the Pontiac Firebird III holds similar dimensions. It is slightly longer than some competitors, offering more cabin and trunk space, and its width of 1838 mm (72.3 inches) also aligns with the average for muscle cars of the time. This parity in size allowed the Firebird III to compete effectively in its segment while providing distinctive styling.

While the exact weight can vary depending on engine and trim level, the Firebird III typically weighs around 1500 to 1600 kilograms (3307 to 3527 pounds). This moderate weight for a muscle coupe enables it to maintain agility and speed while offering solid road grip. Its weight plays a key role in balancing performance, fuel efficiency, and handling.

The Firebird III is designed as a two-door coupe with seating typically for four passengers. Its width of 1838 mm (72.3 inches) and length of 4833 mm (190.3 inches) provide reasonably comfortable front seats and usable rear seating, especially in comparison to smaller sports cars. However, rear space is more suitable for short trips or smaller passengers due to the coupe's sloping roofline and compact rear legroom.

Throughout its decade-long production run, the Pontiac Firebird III maintained consistent exterior dimensions, with minor variations due to facelifts and trim updates rather than structural redesigns. This consistency was typical of the era and allowed owners to expect stable handling and space characteristics. Most dimensional specifications like length, width, and height remained effectively unchanged through the generation.
