Story
1958 Dodge Coronet
The Coronet was Dodge's entry passenger-car line for 1958. Dodge called the six-cylinder path Coronet Standard and the V8 path Coronet Custom, but both belong on one model-year family page. Two- and four-door sedans, two- and four-door Lancer hardtops, and the Lancer convertible were the five passenger bodies. Royal, Custom Royal, Regal Lancer, and the separately named wagon lines remain different identities.
Six, Red Ram, and D-500
The 230-cubic-inch L-head six made 138 gross horsepower. Regular V8 buyers could select the 252-hp 325 two-barrel or 265-hp four-barrel Power Package. The D-500 engine package substituted the new 361 wedge with a 305-hp single four-barrel, a 320-hp dual-four-barrel setup, or the announced 333-hp Bendix electronic-fuel-injection system. The EFI cars were recalled and converted, so an Electrojector claim requires unusually strong serial, component, service, and ownership evidence.
Push buttons, Torsion-Aire, and Total-Contact brakes
A three-speed manual was standard, PowerFlite was limited to the six and regular 325, and TorqueFlite served the V8 paths. Rear-axle ratios followed engine and transmission, with Sure-Grip available for permitted V8 applications. Longitudinal torsion bars and unequal-length control arms carried the front; semi-elliptic leaves located the live rear axle. Total-Contact drums were standard, with body-specific sizing, optional larger drums, and optional vacuum assist.
Swept-Wing details and cabin
Quad headlamps, the broad grille, plain Coronet fin upsweep, rear-mounted Coronet script, and body-specific Lancer roof or convertible structure distinguish the family. The factory brochure emphasizes Magic Fabrics, full-width seating, push-button automatic controls, and optional power equipment, radio, heater, Airtemp air conditioning, and Highway Hi-Fi. Paint, upholstery, two-tone placement, and equipment still require the selector and one car's protected evidence.
Production and proof boundaries
A compiled production sheet reports 77,388 Coronets. Secondary body and engine rows reconcile to that total, but Dodge did not publish a clear D-500 count and no reviewed serial ledger resolves engine, transmission, axle, paint, trim, option, plant, date, or survivor intersections. The seven retained base-price rows describe bodies and base engine classes, not D-500, transmission, accessory, destination, or delivered totals.
