The 1963 Buick Riviera was the production result of GM’s XP-715 design project, first offered to Cadillac before Buick won the chance to build it. Introduced on October 4, 1962, it gave Buick a sharp-styled, four-passenger luxury coupe aimed at the market led by Ford’s Thunderbird. Its 401-cubic-inch V8, available 425-cubic-inch V8, and restrained design made the launch model distinct from later Rivieras.
How did the 1963 Buick Riviera come about?
GM designer Ned Nickles showed design chief William “Bill” Mitchell a rendering for XP-715, a project initially associated with a possible Cadillac and the La Salle name. Mitchell ordered a full-size clay model. Cadillac and Chevrolet passed on the proposal; Pontiac, Oldsmobile, and Buick showed interest. GM held a division competition, and Buick won the right to produce it, according to Hemmings.
Buick wanted an upscale coupe that could attract affluent buyers and compete with the Thunderbird. The production Riviera paired formal, sharp-edged styling with a powerful V8 and chassis tuning intended to keep the car composed while preserving a soft ride. The NB Center describes it as Buick’s first entry into a personal-luxury market created and dominated by the Thunderbird.
1963 Buick Riviera specifications
The NB Center’s collection record describes a 1963 Riviera model 4747: a two-door, four-passenger hardtop built by Fisher Body. Its listed specifications and original base price are shown below; these figures are reported by that collection record, not independently verified here against a factory brochure.
#1 Best Overall
| Specification | 1963 Riviera |
|---|---|
| Wheelbase | 117 inches |
| Overall length | 208 inches |
| Standard engine | 401-cubic-inch overhead-valve V8, 325 hp at 4,400 rpm |
| Optional engine | 425-cubic-inch V8, rated at 340 hp |
| Transmission | Three-speed automatic |
| Original base price | $4,333 |
The NB Center lists power steering, power brakes, and automatic transmission as standard equipment. Hemmings identifies the engines as the 325-hp 401 Wildcat 445 and optional 340-hp 425 Wildcat 465. Engine availability and output changed in later model years, so these figures apply to 1963.
What made the launch model distinctive?
The Riviera’s character came from the combination of taut, formal styling and substantial V8 power. Hemmings describes attention to a low ride height and center of gravity, with body roll limited while retaining a soft ride. The design project’s concealed headlamps did not make the 1963 production car: cost considerations led to exposed quad headlamps beside decorative fender grilles.

That headlamp detail is an easy way to distinguish the first two model years from the 1965 update. The 1963 car also preceded the 1964 addition of Riviera lettering to the taillamps, wheelcovers, and hood ornament, as described by Hemmings.
How many 1963 Buick Rivieras were made?
Hemmings reports production of 40,000 Rivieras for 1963. For context, the same source reports 37,658 for 1964 and 34,586 for 1965. These are source-reported model-year totals, not figures checked here against a GM production ledger.
What changed on the Riviera after 1963?
| Model year | Headlamp and styling details | Engine summary | Production reported by Hemmings |
|---|---|---|---|
| 1963 | Exposed quad headlamps; decorative fender grilles | 401/325 hp standard; 425/340 hp optional | 40,000 |
| 1964 | Exposed quad headlamps; Riviera lettering added to taillamps, wheelcovers, and hood ornament | 425/340 hp standard; dual-carburetor 425/360 hp Super Wildcat optional | 37,658 |
| 1965 | Concealed headlamps; rear-fender scoop trim removed, ribbed rocker trim added, and rear bumper restyled with taillamps set into it | 401/325 hp returned as standard | 34,586 |
The model-year details and production figures in this comparison are reported by Hemmings. They show why the 1963 Riviera should not be described with the concealed headlamps or later engine mix associated with subsequent years.
Restoration note for prospective owners
Hemmings advises checking behind wheel wells and around fender openings, door bottoms, floors, and rocker panels for corrosion. Floor, trunk, and rocker repair panels are produced, but used parts may be needed for major components such as fenders, doors, trunklids, and quarter panels. The source also warns that scarce trim can add cost and complexity. This is a general inspection guide, not an assessment of any particular car or current parts availability.
