The 1955 Dodge lineup, consisting of the entry-level Coronet, Royal, and ornate Custom Royal, was a major departure for the company. Driven almost out of business in 1953 and 1954, the Chrysler Corporation was revived with a $250 million dollar loan from Prudential and new models designed by the legendary Virgil Exner. The Dodge lineup was positioned as the mainstream line in Chrysler's hierarchy, between Plymouth and DeSoto.
The 1955 Dodge was all-new with a longer 120 in (3048 mm) wheelbase and 212.1 in (5387 mm) overall length than the 1954 cars. They shared their basic mechanicals with the De Soto, but featured special styling. These cars lasted through the 1955 and 1956 model years before being replaced by the all-new 1957 design.
There were six body styles and four trim lines for 1955:
The Coronet (and Suburban station wagon) was the base model. This was the only line to feature the 230 in³ (3.8 L) Getaway I6 as well as the 270 in³ (4.4 L) Red Ram V8. Coronets were available in all body styles except the convertible. Sedans feature "Coronet" badges on the fenders, while the station wagons are called "Suburban". Although the hardtop coupe was officially named "Lancer", it wore only "Coronet" badges. Turn signals were standard on the Royal and Custom Royal models but optional on the base Coronet.
The Royal (and Sierra wagon) were the next step up. Featuring only the V8 engine, the Royal also lacked the 2-door sedan and wagon models available in the Coronet line. Early hardtop coupes lack the "Lancer" script, although they were officially Lancers, but later models wore "Royal Lancer" badges.
The flagship model was the Custom Royal. All hardtop coupe and Custom Royal-only convertible models were called "Custom Royal Lancer", and the "Custom Royal" sedan gained the Lancer badge soon after its introduction as well. The Custom line featured unique chrome tailfins (although early model year cars went without this trim), special tail light surrounds, and an upscale interior. Backup lights were standard on the Custom line but optional on all others. The Custom Royal also featured the hemi 270CID Super Red Ram engine.
The La Femme was a special package oriented towards women, who made up an increasing share of Dodge buyers. It came in Heather Rose and Sapphire White colors and included a cape, boots, umbrella, and shoulder bag that matched the floral tapestry-like fabrics. Changes to the car include built-in compartments in the seatbacks to hold these accessories.
The 1956 D-500 was a high-performance model derived from the standard 1956 Dodge but differing in many ways. It included a heavy duty suspension and other chassis upgrades from the New Yorker and Imperial lines, upgraded brakes, and a high-performance 315 in³ (5.2 L) Hemi-head V8. A four-barrel Carter carburetor pushed output to 260 hp (194 kW) and 330 ft·lbf (447 N·m). The 3-speed manual transmission was standard, with the PowerFlite 2-speed automatic as an option. A rare NASCAR-specific option was the D-550-1, which upped power to 285 hp (213 kW). The D-500 originally used only the Coronet 2-door sedan and Royal Lancer hardtop and convertible bodies.
Power came from either a 230 in³ Chrysler Flathead engine straight-6 or one of two 270 in³ V8s. The regular Red Ram V8 was standard on the Royal and optional on the Coronet. A Hemi-head V8 was standard on the Custom Royal, called the Super Red Ram. A rare Power Pack was optional, consisting of a four-barrel Carter carburetor and dual exhausts good for 193 hp (144 kW) with the Hemi engine.
Two transmissions were offered: a three-speed manual with optional overdrive and Chrysler's two-speed PowerFlite automatic. The PowerFlite was controlled by a dash-mounted lever, though this was changed to a push-button setup for 1956.
The cars used a special coil spring/kingpin suspension in front and regular leaf springs and a live axle at the rear. Power steering was optional. A six-volt electrical system was updated to 12 volts in 1956.
