This record's own dek describes 1973 as the year a hatchback body appears in the source body table for the first time, with the Super Sport offered with any engine per the source; the enthusiast-compiled total stands at 369,509 cars, of which 35,542 were Super Sports. This record's own overview states that every count comes from the same single enthusiast compilation, NovaResource.org, with ratings again carried as SAE net figures for the year.1

Three body-style rows are documented, 91,012 hatchbacks, 194,197 cars in the source's own "2 Door Sedan" column, and 84,300 four-door sedans, with the 35,542-car Super Sport figure kept separately scoped rather than folded into any of them. Four engines are documented: the 250 six coded L22 at 100 net hp, the 307 V8 coded L14 at 115 net hp, and two 350 V8s, L65 at 145 net hp and L48 at 175 net hp. The installation figures in this record's production table again sum exactly against its own V8 cylinder-count row: 142,798 307 V8 cars plus 120,274 350 V8 cars equal the 263,072-car V8 row also documented here.1

Four transmissions carry their own installation counts: 37,613 three-speed manuals, 8,140 M20 four-speeds, 78,194 M35 Powerglide automatics, and 245,562 M38 Turbo Hydra-Matic 350 automatics, the last figure alone accounting for two-thirds of this record's own 369,509-car total for the year. This record's own key facts cite Chevrolet's price schedule effective December 4, 1972 directly, listing Nova base prices from $2,376.70 for the six-cylinder two-door coupe to $2,791.86 for the V8 Custom hatchback, with the Nova SS option priced separately by body: $79.00 on Custom models, $107.50 on the coupe, and $122.50 on the hatchback.

This record documents an extensive, individually priced options list running past forty codes, including six separate Nova SS rows split by body style and by black (Z26/YF8) or white (Z26/ZR8) striping, all matching the three body-specific prices in this record's own key facts. Also documented are the L48 350 four-barrel at $102 with a note that it requires power disc/drum brakes, the Z54 Interior Decor/Quiet Sound Group at $33 and standard equipment on Custom models, and six factory sky-roof color choices, each priced identically at $179.00.

Twenty-nine solid exterior colors and nineteen interior trim codes are documented, a noticeably larger palette than this record's earlier sections describe for other parts of the car. This record's own specifications section is unusually developed for the year, carrying a 111-inch wheelbase, 194.3-inch overall length (195.1 inches on Custom models with impact strips), 72.4-inch width, curb weights for six body and series combinations ranging from 3,137 lb to 3,256 lb, and a separately stated 210-lb weight addition for the L48 350 paired with Turbo Hydra-matic; its performance section remains empty.

This record's own identification section documents cowl-tag series XX for Nova and XY for Nova Custom, body codes for the hatchback, coupe and sedan, and two assembly-plant abbreviations, L for Van Nuys, California and W for Willow Run, Michigan, restating that any engine could be ordered with the Super Sport for 1973. Its conflicts section logs two disputes: a two-unit gap between this record's 369,509 total and Wikipedia's 369,511, and a Super Sport price conflict where Wikipedia's single $123 figure is noted in this record's own treatment as matching only the hatchback's $122.50 price rounded, against the factory schedule's three body-specific figures which this record's own treatment says the page should present instead.1

The numbers

1973 Chevrolet Nova — Hatchback appears in the source body table; SS offered with any engine per the source. Enthusiast-compiled production: 369,509 cars; Super Sport 35,542.

Coverage: Partial — researched sections are shown; missing ones are not yet sourced. Researched through 2026-09-22.

Every figure is labeled with how sure we are. Reported means a manufacturer, registry, or reference figure we cite but have not reconciled against factory records ourselves. Disputed means credible sources disagree and both are shown. Rows are separately scoped; don't add them together unless the note says they make up a total.

All counts are from one enthusiast compilation (NovaResource.org), which says its numbers were compiled from many sources and carry no guarantee; the underlying Chevrolet documents were not seen. Status is reported, or estimated where the source itself marks a value approximate or rounded.

Rows are separately scoped. Body, cylinder, engine-displacement and transmission rows each describe the whole line from a different angle and must not be added across groups.

A value missing from this table was marked unavailable ("?") or zero in the source and is not shown; missing does not mean zero.

Also in 1973

  • AMC AMX The Javelin AMX's best year. 5,707 were built, a quarter of them with the 401, alongside the Trans Am Victory decal and the Pierre Cardin interior.
  • AMC Gremlin X and Spirit AMX The V8 Gremlin X continued, with new stripes and an available Levi's denim-look interior. No production split has been found.
  • AMC Javelin The SST name dropped away and new twin 'TV-screen' taillights arrived. Javelin production reached 25,195, alongside the Trans Am Victory decal package.
  • Buick Riviera Stage One (260 hp net) joined a separate GS handling package; 1,234 Stage Ones and 3,933 GS cars of 34,080.
  • Buick Skylark Gran Sport, GS and GSX On the new Colonnade A-body the GS became a Century Gran Sport package; 6,637 were built, 728 with the 455 Stage 1.
  • Chevrolet Chevelle and Malibu SS The Colonnade Chevelle's only SS year: RPO Z15 on the Malibu coupe and, for the first and only time, the station wagon, with a 245 net hp 454 available.
  • Chevrolet El Camino SS The new Colonnade El Camino could still be ordered with RPO Z15 SS equipment; no El Camino SS count was found.
  • Dodge Challenger The six was gone: every 1973 Challenger hardtop had a V8, the 318 standard and the 340 optional, with the Rallye now sold as a package.
  • Dodge Charger The Charger's best-selling year of the original era, 119,318 cars, came as the 440 lost its Magnum name and the car moved toward personal luxury.
  • Dodge Dart GTS, Swinger and Demon Renamed Dart Sport, the fastback's 340 model sold 11,315 in the 340's final year.
  • Ford Maverick Grabber The 200 six became standard as the 170 was dropped; Classic Industries counts 32,350 Grabbers.
  • Ford Ranchero GT The Ranchero GT continued on the 1972-76 Ranchero; 15,320 GTs were built, per reference-site counts in the Standard Catalog lineage.
  • Ford Thunderbird The 429 4V was standard and the 460 4V optional in the sixth generation's best-selling year.
  • Ford Torino The 1973 Torino kept the 1972 body behind a heavier bumper; the Gran Torino Sport fell to 51,853 SportsRoofs and 17,090 hardtops while the 351 Cobra Jet remained the performance engine.
  • Mercury Cougar The last Cougar convertible and the last 351 Cobra Jet year, with production up to 60,629 as buyers shifted to the XR-7.
  • Mercury Montego GT The Montego GT fastback's second and last year; a vehicle profile reports 4,464 built.
  • Oldsmobile Cutlass, 4-4-2 and Hurst/Olds On the new Colonnade Cutlass the 4-4-2 was a W-29 appearance and handling option, and the Hurst/Olds came in white or, for the first time, black: 1,097 built.
  • Plymouth Barracuda and 'Cuda V8 only: the 318 became standard on both Barracuda and 'Cuda, the 340 moved to the option list, and production rose for the only time after 1970.
  • Plymouth Duster 340 and 360 The 340's last year in the Duster produced 15,731 cars with power front disc brakes now standard, and the Spacemaker Pak fold-down rear seat joined the line.
  • Plymouth GTX, Belvedere and Satellite For 1973 the GTX name survived only through the Road Runner's optional 440 four-barrel, which came with TorqueFlite only; Mueller's Muscle Car Source Book counts 749 of them.
  • Plymouth Road Runner A secondary count puts production back up to 19,056, the highest of the 1971-1974 Satellite-based years.
