1973 Buick Regal I Sedan Dimensions, Size & Specs

The vehicle stands 1374 mm (54 inches or 4 feet 6 inches) tall, which gives it a relatively low and sleek profile for a full-size sedan. This moderate height helps in reducing aerodynamic drag compared to taller vehicles, potentially improving fuel efficiency slightly and enhancing high-speed stability. The lower height also contributes to easier entry and exit for passengers, while complementing the classic streamlined styling typical of the 1970s Buick design language.

The curb weight of the Buick Regal I Sedan ranges between 1787 kg to 1935 kg (approximately 3940 to 4266 pounds). This weight range is considerable for a sedan, reflecting the robust build and substantial materials used during that era. Heavier weight can contribute positively to a stable and smooth ride, especially at highway speeds, but it also tends to reduce fuel efficiency and may impact acceleration performance compared to lighter vehicles. Drivers can expect a solid, comfortable driving experience balanced by these weight implications.

The luggage capacity of the 1973 Buick Regal I Sedan ranges from 413 liters to 442 liters (about 14.6 to 15.6 cubic feet). This generous boot space reflects the vehicle’s design focus on practicality and family use, allowing ample room for groceries, luggage, or other cargo. For its time, such volume was quite competitive among full-size sedans, making it convenient for long trips or everyday use. The trunk size accommodates a wide variety of cargo, emphasizing the vehicle’s versatility.

The Buick Regal I Sedan features a ground clearance of 145 mm (approximately 5.7 inches). This is a moderate clearance typical of sedans from the 1970s, which strikes a balance between road handling and ride comfort. It is sufficient for urban and highway driving but might be less ideal for rough or uneven terrain. Ground clearance at this level helps maintain a lower center of gravity, which improves vehicle stability especially during cornering and reduces aerodynamic drag.

The Buick Regal I Sedan rides on 14-inch rims and offers tire size options including 185/75 R14, 195/70 R14, 205/65 R14, and 215/60 R14. These tire sizes were typical for full-size sedans in this period, balancing ride comfort, handling characteristics, and durability. The choice of multiple tire widths allows owners to prioritize either a smoother ride or potentially enhanced grip and stability, depending on their preference or regional availability.

Yes, the 1973 Buick Regal I Sedan, with its length of 5486 mm (18 feet) and width of 2007 mm (6 feet 7 inches), generally fits comfortably in a standard residential garage. Most standard garages typically measure at least 6 meters (20 feet) in length and about 3 meters (10 feet) in width, allowing adequate space not only for parking the Regal but also for opening doors and maneuvering around the vehicle. However, due to its wide body, garages with narrower widths might feel tighter, so it’s advisable to measure garage dimensions before parking.

The 1973 Buick Regal I Sedan maintained much of the large size and full-size sedan character of its predecessor but introduced some refinements. In terms of length and width, the 1973 model measures 5486 mm in length and 2007 mm in width. While direct predecessor dimensions vary by model year, generally there was a trend toward slightly longer and wider vehicles in the early 1970s to accommodate more interior space and comfort. These dimensional tweaks improved passenger space and road presence without drastically changing the car's footprint, emphasizing gradual evolution rather than revolution.

Compared to other American full-size sedans of the early 1970s, such as the Chevrolet Impala, Ford LTD, and Chrysler New Yorker, the Buick Regal I Sedan is similarly large, with its 5486 mm length and 2007 mm width placing it firmly within the full-size category. Many competitors had lengths ranging from around 5300 mm to 5600 mm with widths close to 2000 mm, making the Regal competitive in interior space and road presence. Its somewhat lower height at 1374 mm can help it appear sleeker than some rivals, which often featured taller profiles, emphasizing a balance of style and traditional American sedan size.

The Buick Regal I Sedan, produced from 1973 to 1977, represents the first generation of the Regal nameplate and marks Buick's response to the growing market for personal luxury sedans in the 1970s. This period was notable for large, comfortable cars with advanced features for their time and a focus on cruising comfort. The Regal combined Buick’s luxury touches with solid performance and spacious interiors. These years also reflect a transitional era in U.S. automotive design and regulations, handling emissions and safety changes while maintaining traditional styling cues beloved by customers.
