1973
The 1973 model year Darts received new front styling with revised fenders, grille, header panel, and hood. Massive front bumpers were installed to comply with new federal regulations, as well as side-impact guard beams in the doors and new emission control devices. New single-piston disc brakes replaced the more complex 4-piston units offered from 1965 to 1972. Chrysler's new electronic ignition system was standard equipment on all engines, and starter motors were revised for faster engine cranking. The K-frame was modified to accommodate a new spool-type engine mount that limited engine roll to 3. The upper ball joints were upgraded to the larger B-body units. Along with these chassis changes, the wheel bolt pattern on Darts with disc brakes was enlarged from 4 in (101.6 mm) to the 4.5 in (114.3 mm) pattern common to the larger B- and C-body Chrysler-built passenger cars. Darts with 4-wheel drum brakes continued with the smaller bolt pattern. The standard rear axle was still the 7" unit, but the heavy-duty option was now an 8" item rather than the previous 8" rear axle. Standard rear axle ratios were 2.76:1 with automatic transmission and 3.23:1 with manual, though other ratios were available. Vent wings were deleted from the Swinger but not from the 4-door sedans. A new "Quiet Car" package was available, consisting of extra sound insulation, premium exhaust hangers and an exhaust resonator. The Demon fastback was renamed "Dart Sport" in response to Christian groups' complaints about the 'Demon' name and devil-with-pitchfork logo. The high-performance model thus became Dart Sport 340, and 1973 saw styling changes to go along with the name change. The Dart Sport received the same new front end as the other Darts, and its taillights were changed to two lights per side, each with a chrome trim ring. These would remain unchanged through the 1976 model year.

1974
In 1974, the US federal 5 mph (8.0 km/h) bumper impact standards were expanded to cover rear bumpers as well as front ones, and as a result the Swinger and Dart sedan's rear bumpers grew much more massive. Taillights larger than the previous year's items were set above the rear bumper, rather than within it. Shoulder and lap belts were finally combined in all Chrysler products into a retractable, inertia-sensitive, single-buckle design Chrysler called "Unibelt", replacing the difficult-to-use separate lap and shoulder belts that had been installed through 1973. The Arab oil embargo of 1973, increased sales of smaller cars in the U.S. Dodge introduced the Dart SE (Special Edition) in mid-1974 as a four-door sedan and two-door hardtop. The SE included velour high back bucket seats with folding armrest, carpeted door panels, woodgrain instrument panel and deluxe wheel covers along with a TorqueFlite automatic transmission as standard equipment. The SE came equipped with the "Quiet Car" package introduced in 1973. The air conditioning system available on all Darts had increased capacity, quicker cooldown and lower minimum temperatures.[36] An evaporator pressure regulator valve, long used on larger Chrysler products, varied the compressor's capacity without cycling the clutch. The Dart Sport 340 was replaced by the Dart Sport 360 245 Bhp. as the 360 cu in (5.9 L) V8 engine replaced the 340 cu in (5.6 L) engine discontinued after 1973.

1975
The 1975 models were virtually identical to the 1974s, except for a new grille and that California and some high-altitude models were equipped with catalytic converters and so required unleaded gasoline. All 1975 models were required to pass a roof crush test and to meet this stringent requirement, additional reinforcements were added to all Dart 2-door hardtops. Heavy gauge steel in the windshield pillar area had been incorporated into the windshield, pillar and roof design. Darts were also equipped with an improved energy absorbing steering column which used multiple slots in the column jacket to replace prior used convoluted mesh design. At impact, force applied to the steering wheel curled the column jacket back over a mandrel mounted on the floor. Federal Motor Safety Standards briefly required that the front seat belts include a starter interlock system that prevented the engine from starting unless the front seat outboard occupant and the driver fastened their belts. The 198 slant-six engine was discontinued and the 225 became standard equipment on all models. As in 1974, the 360 V8 was limited to the Dart Sport 360 model. A 4-speed manual transmission was offered with the 6-cylinder engine for the first time in the North American market since 1965, and with a new 30% overdrive 4th gear ratio.[37] It was Chrysler's first application of overdrive since 1959. The final drive ratio in fourth gear was 2.36:1 on the slant-six cars equipped with 3.23:1 rear axle, and 2.15:1 on the V8s equipped with 2.94:1 rear axle. The result was less engine noise and wear and greater fuel economy. Also for 1975, heaters had 14% more heating capacity than in the previous year's models. The added capacity was the result of adding a third speed to the blower system, which provided 20% greater air flow at maximum setting.[36] The electrically heated backglass defogger grid timer cycle was doubled to 10 minutes. Additionally, sound insulation was improved.

1976
1976 was the Dart's final year in the North-American market. The rear-view mirror was mounted on the windshield rather than from the roof. Front disc brakes became standard equipment on 1 January 1976 in accord with more stringent U.S. federal brake-performance requirements, and a new foot-operated parking brake replaced the under-dash T-handle used since the Dart's 1963 introduction as a compact car. The grille's parking lamps were cast in amber, whereas the previous years had clear lenses with amber-colored bulbs. The Dart Sport 360 was dropped as a separate model in 1976, but the 360 cu in (5.9 L) four-barrel, dual exhaust (without catalytic converters) V8 was a $376 option (except in California) for the $3,370 Dart Sport V8 models with automatic transmission. Car & Driver magazine tested the Dart Sport 360 in the April 1976 issue, pitting it against the Chevrolet Corvette and Pontiac Trans Am, and found its top speed of 121.6 mph (195.7 km/h) to be second to the Corvette's 124.5 mph (200.4 km/h).
