The production Riviera (unusually for a GM product) shared its bodyshell with no other model. It rode a cruciform frame similar to the standard Buick frame, but shorter and narrower, with a 2.0 in (51 mm) narrower track. Its wheelbase of 117 in (2972 mm) and overall length of 208 in (5283 mm) were 6.0 inches (152 mm) and 7.7 in (196 mm) shorter, respectively, than a Buick LeSabre, but slightly longer than a contemporary Thunderbird. At 4190 lb (1900 kg), it was about 200 lb (90 kg) lighter than either. It shared the standard Buick V8 engines, with a displacement of either 401 in³ (6.5 L) or 425 in³ (6.9 L), and Twin Turbine automatic transmission. Brakes were Buick's standard "Al-Fin" (aluminum finned) drums of 12 in. (304.8 mm) diameter. Power steering was standard equipment, with an overall steering ratio of 20.5:1, giving 3.5 turns lock-to-lock.The Riviera's suspension used the same basic design as standard Buicks, with double wishbones front and a live axle located by trailing arms and a lateral track bar, but the roll centers were raised to reduce body lean. Although its coil springs were actually slightly softer than other Buicks, with the lighter overall weight, the net effect was to make the Riviera somewhat firmer. Although still biased towards understeer, contemporary testers considered it one of the most roadable American cars, with an excellent balance of comfort and agility.The Riviera was introduced on October 4, 1962 as a 1963 model, with a base price of $4,333, although typical delivered prices with options ran upwards of $5,000. Production was deliberately limited to 40,000 or less to increase demand.With the same power as the larger Buicks and less weight, the Riviera had sparkling all-around performance: Motor Trend magazine found it capable of running 0-60 mph (0-96 km/h) in 8 seconds or less, the standing quarter mile in about 16 seconds, and an observed top speed of 115 mph (184 km/h), although 125 mph (200 km/h) was feasible with a longer run. Fuel consumption was a meager 13.2 mpg (18.4 L/100 km).The Riviera continued with minimal trim changes for 1964, differing mainly in substitution of the old Twin Turbine for the new Super Turbine 400. This was the first year that the Stylized "R" emblem was used on the Riviera, a trademark that would continue throughout the remainder of Riviera's 36-year production run. Under the hood, the 401 (6.5L) was dropped in favor of the 425 in³ (6.9 L) V8, with 220 SAE HP. A 'Super Wildcat' version was optionally available, with dual Carter AFB four-barrel carburetors, rated at 240 SAE HP.Changes for 1965 included the introduction of the Gran Sport option, which included the dual-quad Super Wildcat 425 V8, a numerically higher 3.42 axle ratio, dual exhausts, and stiffer, heavy-duty suspension. The 401 (6.5 L)V8 returned as the standard Riviera engine and the Super Turbine 400 transmission now had a variable pitch torque converter like the old Twin Turbine Dynaflow had two years before. Externally, the headlamps were concealed behind clamshell doors in the leading edges of each fender, as in the original design. Further back, the non-functional side scoops between the doors and rear wheel arches were removed, and the taillights were moved from the body into the rear bumper. A vinyl roof became available as an option, initially offered only in black.Total sales for the three model years was a respectable 112,244. All in all, the Riviera was extremely well-received and considered a great success, giving the Thunderbird its first real competition.This article is licensed under the GNU Free Documentation License.
