The 1958 Chevrolet Grows
In Size
Chevrolets moved to larger bodies for 1958 – over 9 inches longer, and the over all chassis had a wheelbase increase of 2.5 inches. Styling was radically different and would signal a major change in looks going forward.
General Year Information – 1958 Chevrolet Facts
By adopting an all-new Safety Girder chassis for 1958, Chevrolet brought to market a completely re-engineered and restyled line. Body revisions included lower, wider, longer sheet metal, a new front end with dual headlamps, gull-wing rear fender with rear deck sculpturing and revamped side trim. All 1958 Chevrolets with V-8 engines had additional, large, V-shaped ornaments on the hood and deck, or in the case of wagons, the tailgate.
New names were given to the two lower series: Del Ray and Biscayne, replacing 150 and 210 designations. And models available within each line were altered as well. The sedan delivery was cataloged as a conventional model, but strangely, not with the station wagons – now a sub-series unto themselves.
Gas filler now under door in trunk latch lid panel. On Impalas the center tail lens housed a backup lamp. A great deal of bright metal trim on 1958 Chevrolets was made of aluminum.
NOTE: The model numbering system changed in 1958. Model numbers and Body Style Numbers were now identical.

The 348 CID V-8 engine was called “Turbo-Thrust” and it was unrelated to the Small Block V-8. The offset valves resulted in the scalloped rocker covers, giving it a distinctive look. The offset valves were designed to reduce the block’s overall length To Learn more about the 348-427 V-8 click HERE
After slow sales & a lack of buyer enthusiasm, Chevrolet dropped the 2-door Nomad in 1958 and renamed the 4-door Bel Air Townsman the Nomad. Sales went up by about 4-times. You can see the Nomad in the 1958 Brochure HERE.

DEL RAY SERIES: 1100 I-6 & 1200 V-8. The Del Ray nameplate was now the Chevrolet entry series. “Del Ray” nameplates filled the rear fender coves of the four models in the low-priced line. The styling of the line had single belt moldings and lacked bright metal side window trim. The Series Station Wagon was called “Yeoman” and was trimmed as a Del Ray.
Del Ray interior appointments were the most basic Chevrolet offered with a standard steering wheel, rubber floor mats and little bright highlights on the dash, seats, and door panels.
BISCAYNE SERIES: 1500 I-6 & 1600 V-8. Only two body styles were available under the Biscayne name, although two Brookwood station wagons used the same level trim. The passenger car styles had “Biscayne” in script at the leading edge of the rear fender cove, and the station wagons had “Brookwood” in script in the same location. Biscayne side trim moldings outlined the upper and lower edges of the cove but did not connect. Ahead of the cove, a bi-level belt molding, with slight forward taper, was installed. This belt molding was connected to the single, lower cove outline trim at the rear.
Like the Del Ray models, Biscaynes came standard with small hub caps, no sill moldings, and no fender ornaments, but they did feature slightly up-market interior trims. The Series Station Wagon was called “Brookwood” and was trimmed as a Biscayne.
BEL AIR SERIES: 1700 I-6 & 1800 V-8. This series was the highest trim and a new model was added, the Impala, that was even more luxurious. (Impala models are covered here as a separate model. though not considered as such in 1958).
The base Bel Air had the series name in script and a Chevrolet crest at the rear of the coves. The upper edge of the coven was outlined with a single level molding that slashed down and back, below the body belt dip, to intersect an elaborate horizontal molding arrangement. This could best be described as a “spear-shaped” molding. It had an indented concave contrast band towards the rear, and a horizontally grooved, missile-shaped “spear tip” at the front. There were also four chevrons on the sides of the front fenders, four short vertical strips on the lower rear fender bulge, front fender top ornaments, chrome outlined side windows, grooved rear roof pillar beauty plates and full wheel discs.
Interior appointments were rich and luxurious. The convertible was moved to the new Impala and increased in price by $300. The Bel Air Station wagon wad called “Nomad” and was trimmed as a Bel Air with a tailgate replicating the famous 1957 Nomad.
Impala Models – part of the Bel Air line in 1958. The Impala sport coupe and convertible were even more impressive than the Bel Air models. Trim features included “Impala” in script and a special Impala insignia, as well as crossed-flag emblems at the front of the cove; broad, ribbed body sill panels, and large, faux chrome plated air scoops ahead of rear wheel wells. Significant, and a treatment that would mark Impalas going forward until 1966 was a triple tail lamp treatment that replaced two taillights on other models. The Impala sport coupe had a chrome-edged, rear facing dummy air scoop and curved contour crease molded into the back of the roof.
On the inside, a competition style two-spoke deep hub steering wheel with Impala medallion was fitted. The dashboard had “Impala” in script as well. There was a chrome rear radio speaker grille, again, with “Impala” in script and medallion between rear seat back dip. Interiors were unique to the Impala and more sport-like in execution.
