1975 Pontiac LeMans: catalytic converters and RTS
Catalytic converters, standard radial tires and Radial Tuned Suspension arrive, the 455 leaves the LeMans, and the GT option becomes an automatic-only V8 package.
United States · researched through 2026-09-23
This record's own dek states that catalytic converters, standard radial tires, and Radial Tuned Suspension arrive for 1975, the 455 leaves the LeMans, and the GT option becomes an automatic-only V8 package. This record's own overview states that Pontiac's 1975 intermediate brochure lists the Grand LeMans as a two-door Colonnade hardtop coupe and a four-door sedan, the LeMans Sport Coupe two-door, and the LeMans two-door and four-door, with the 250 six and a column-shift three-speed standard, Turbo Hydra-matic standard on the Grand LeMans, and 350 two-barrel, 350 four-barrel, and 400 four-barrel V8 options, the only transmission option being Turbo Hydra-matic.
This record's own overview states that Radial Tuned Suspension, with GM-specification FR78-15 steel-belted radials, front and rear stabilizer bars, and firm shocks, was standard on the LeMans and LeMans Sport Coupe, together with the Maximum Mileage System of High Energy Ignition, a catalytic converter, and unleaded fuel. This record's own key facts state that the 1975 GT option, for two-door LeMans and Sport Coupe models, required a V8 and Turbo Hydra-matic and included a blacked-out grille, hood scoops, body-colored sport mirrors, wheel opening moldings, special Rally II wheels, GR70-15 white-letter steel-belted radials, and GT striping and identification.
Those same key facts state that the brochure lists no 455 and no manual transmission other than the standard column-shift three-speed for the 1975 LeMans. This record's own production section documents a Curbside Classic sales figure of 48,589 for the LeMans line, with the article giving no source or basis and not stating whether Grand LeMans cars are included, alongside an uncited compiler total of 27,110 for the Grand LeMans alone, which likewise does not state whether Safari wagons are included.1
This record's own production rows document nine separately scoped catalogue body totals, from 1,393 Grand LeMans Safari two-seat wagons to 23,817 LeMans Sport two-door hardtops, each an all-engine total that this record's own notes state must not be added into a series total unless a source states one. Those same notes state that no production split by body, engine, or GT option was found for 1975, and name the Standard Catalog of Pontiac, a 1975 Pontiac Accessorizer, Pontiac Historic Services, and the 1975 AMA specifications as the best remaining sources.2
This record's own prices section documents fourteen catalogue price points across nine body styles, from $3,590 for a six-cylinder LeMans two-door hardtop to $4,882 for a V8 Grand LeMans three-seat Safari. This record's own engines section documents the 250 six and 350 two-barrel, 350 four-barrel, and 400 four-barrel V8s without horsepower figures in this record, alongside a transmissions section documenting the standard column-shift three-speed on LeMans and Sport Coupe and Turbo Hydra-matic as the only transmission option, standard on Grand LeMans and required with the GT option.2
Twenty-four exterior colors are documented for the year without production counts, and four interior trims are documented from a standard LeMans cloth-and-vinyl bench to LeMans Sport Coupe Morrokide buckets offered at no additional cost. This record's own specifications section documents a 112-inch two-door wheelbase against 116 for four-doors, a 208.0-inch overall length against 212.0 for four-doors, a 77.4-inch width, and standard FR78-15 radials against GR70-15 white-letter tires with the GT option, and its performance, identification, and conflicts sections are all empty for the year.3

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.

No production split by body, engine or GT option was found for the 1975 LeMans. The rows below are separately scoped secondary figures (a sales number for the LeMans line and a production total for the Grand LeMans series alone) and must not be added together.
The paint list is PPG's 1975 Pontiac chart, whose header covers LeMans among other lines but which does not give per-series availability.
Best sources that would close this gap: the Standard Catalog of Pontiac 1926-2002 (production by series and body), a 1975 Pontiac Accessorizer or order guide (option codes and prices), Pontiac Historic Services, and the 1975 Pontiac AMA specifications.
Body-style rows from the Standard Catalog of Pontiac 1926-2002 are catalogue production totals of unstated accounting basis and do not identify sporting packages; they are separately scoped from any secondary totals already in this record and must not be combined with them.

- AMC Gremlin X and Spirit AMX Catalytic converters arrived, and steel-belted radials became standard with the X package.
- Buick Riviera Stage One dropped; the GS handling package continued on 3,101 of 17,306 cars.
- Buick Skylark Gran Sport, GS and GSX The endpoint: the Gran Sport survived only as a Century coupe trim package with the 231 V-6 or 350 V-8; no 455 was offered.

- Ford Ranchero GT The Ranchero GT continued on the 1972-76 Ranchero; 6,114 GTs were built, per reference-site counts in the Standard Catalog lineage.

- Plymouth Road Runner The Road Runner moved to the Fury host for one year.
- Pontiac Firebird and Trans Am The year the Trans Am took over the line: 27,274 built, more than twice the Formula.
- Pontiac Grand Am The last of the Colonnade Grand Ams: catalytic converter, a $4,887 start, and 10,679 built.
- Pontiac Grand Prix The LJ joins the line; the 455 is down to 200 hp net.
