The 1975 Dodge Dart and Swinger (Valiant, Duster, and Scamp were similar)

For 1975, the Dart continued essentially unchanged in most of its essentials. Cosmetic changes were minor, with a new, less pointy grille; new lower deck trim applique and up-and-over stripes on Dart Sport and Dart 360 Sport; new fabrics (including velour), new seats (including various buckets), and new colors (silver, red, two golds, and cinnamon).

Following the success of the Plymouth Valiant Brougham and Dodge Dart SE, which provided an upscale feel and appearance to the aging but still competitive small cars, Dodge continued selling four-door SE sedans and two-door SE hardtops. New for all SE models was a chrome plated grille, and red vinyl roof (added to the existing green, white, black, and parchment options). More colors were available for the color-keyed SE wheel covers.

Valiant, Duster, and Dart together claimed a whopping 28% of America’s compact car market — well more than double Chrysler’s overall market share.

The essentially identical 1976 Dodge Dart Sport hit 121.8 miles per hour in a Car & Driver test, easily beating the Ford Mustang II Cobra (106 mph) and Pontiac Firebird Trans Am (118 mph). It was, in fact, beaten only by the Chevrolet Corvette L82, which only went up to 124.5 mph.

Transmissions

The Darts’ most popular transmission to use the three-speed TorqueFlite, with a part-throttle kickdown to eliminate the need to floor the gas, providing greater responsiveness, smoother driving, and lower gas consumption. It was an extra-cost option on all but SE and Dart 360, and was generally column mounted. The Dart Sport and Dart 360 Sport (when equipped with bucket seats and consoles) used the same transmission, but mounted in the console, with a button push required to move from Drive to lower gears, and from Neutral to Park or Reverse.

transmissions

Three manual transmission options were available, all synchronized in all forward gears; The base three-speed had either the traditional column mounted shifter or a floor mount; the floor mounted shifter was an extra cost option. A four speed with a Hurst shifter was available on the Dart Sport with Rallye package, and included a reverse warning light.

fuel pacerInteresting options for 1975 included a crank-operated metal sun roof (which tilted open) on most models; a folding rear seat for extra storage on Sport (increasing hauling capacity to 35.6 cubic feet), with included trunk floor carpeting and side trim panels; the Fuel Pacer, which illuminated the fender mounted turn signal light when the car was given too much gas; electric and forced-air rear defoggers; and Sure-Grip differential (similar to Posi-Trac in that when one rear wheel lost grip, power was transferred to the other), which required either disc brakes or a V8 engine. A heavy duty suspension, standard on Dart 360 Sport, was optional on all models, with heavy duty front torsion bar springs and rear leaf springs, and a front antisway bar. Three-speed electric wipers and washers were available on all models as an option.

Instrument panel

The instrument panel on all Dart models had simulated wood-grained trim on the instrument panel cluster; it went across the full instrument panel, including the glove box door, on SE, Custom, and Swinger. The instrument-panel padding was non-reflecting.  Gauges were provided for engine temperature, alternator and fuel, with lights for low oil pressure and brake malfunction.  Ventilator doors under the dash could be opened to allow fresh air to flow in (unless air conditioning was installed).
