1970 Dodge Dart IV Swinger Hardtop (facelift 1970) Dimensions, Size & Specs

The 1970 Dodge Dart IV Swinger Hardtop has a width of 1770 mm (69.7 inches), which is slightly narrower than many contemporary coupes. Modern performance and luxury coupes often range from 1800 mm (70.9 inches) to over 1900 mm (74.8 inches), meaning the Dart’s width offers a more compact footprint, making it potentially easier to maneuver in tighter urban environments while still maintaining classic styling.

The 1970 Dodge Dart IV Swinger Hardtop comes equipped with rims sized 4.5J x 14, paired with tires sized 185/70 R14. The 14-inch rim size with relatively narrow 185 mm wide tires (about 7.3 inches) and a 70% aspect ratio offers a balance between ride comfort and handling for its time. The tire’s taller profile (70% of width) helps absorb road imperfections, delivering a smooth ride, while the narrower width aids in easier steering but might limit grip compared to modern wider tires.

With a height of 1346 mm (or roughly 53.0 inches), the 1970 Dodge Dart IV Swinger Hardtop sits lower than many modern cars, contributing to a sleeker silhouette intended to reduce air resistance. This relatively low profile aids in a lower center of gravity, which can support more stable handling characteristics especially during cornering, although suspension technology of the era may limit performance compared to today’s vehicles.

Official curb weight data for the 1970 Dodge Dart IV Swinger Hardtop is not provided here, but vehicles of this class and period typically weigh between 1300 kg to 1600 kg (approximately 2866 to 3527 lbs). This moderate weight enables a sturdy and composed ride, with enough mass to ensure stability at speed, although it may result in less fuel efficiency and require more effort to achieve rapid acceleration compared to lighter modern cars.

A standard residential garage typically measures about 2400 mm (8 feet) wide and 4800 mm (16 feet) deep. The Dodge Dart IV Swinger Hardtop measures 4978 mm (196.0 inches) in length, making it slightly longer than the average garage depth. While it is possible to park the car inside, extra care or a slightly larger garage space may be required to ensure sufficient room for opening doors and moving around the vehicle comfortably.

Compared to earlier Dodge Dart generations, the Swinger Hardtop facelift of 1970 retained much of the overall size and proportions but featured subtle design tweaks for a refreshed appearance. The length of approximately 4978 mm was consistent with or slightly longer than previous models from the late 1960s, while width and height remained similar, maintaining the classic coupe stance. These incremental dimensional changes helped improve road presence without significantly affecting maneuverability.

In comparison to other American coupes of the early 1970s like the Chevrolet Nova or Ford Maverick, the Dart IV Swinger Hardtop is similar in length and width but tends to be a bit lower in height, at 1346 mm (53 inches). This lower profile gives it a sportier look. Its length of roughly 4978 mm falls into the mid-size range, which aligns closely with competitors, making it a solid choice dimensionally among contemporaries.

The 1970 Dodge Dart IV Swinger Hardtop, being a classic coupe, typically accommodates up to five passengers with two front bucket or bench seats and a rear bench seat. Interior dimensions were designed to offer reasonable comfort for its class, featuring a spacious front row and adequate legroom in the rear for smaller adults or children. However, headroom and rear seat space are generally more limited compared to modern vehicles, reflective of styling and safety standards at the time.

The 1970 facelift of the Dodge Dart IV Swinger Hardtop brought cosmetic enhancements such as revised front and rear styling elements including lighting and grille updates, contributing to a fresher look. Although core mechanical aspects remained similar to prior models, attention to trim detail and optional engine improvements helped maintain competitiveness. The facelift balanced classic muscle car aesthetics with evolving 1970s safety and emissions regulations.
