1981 Riviera advertising
The 1981 Riviera was stressed by the full-time Buick catalog as being on the "leading edge of Detroit technology" by combining weight-saving materials and engineering approaches, interesting synergistic approach to alluding of big changes.
The "egg-crate" grill gives the 1981 Riviera a whole new look
New changes this year came in the form of a redesigned grille folks called egg crate. Self-sealing US Royal tires were offered for the first time this year, along with a new "fluidic" windshield washer that used no moving parts to spray fluid in a fan pattern on the windshield.

This year the new "T-Type" replaced the "S-Type" with major refinements. New black accents and black side mirrors, along with sportier seats in cloth or leather were added, and the dashboard came with the simulated wood grain with the T-Type designation above the radio. The T-Type also came with a new, sportier leather wrapped steering wheel with the T-Type logo in the center, and all-new aluminum wheels with a distinctive R logo on the cap. New this year was the "Grand Touring Suspension" intended for quicker ratio steering and increased road feedback without a rough ride. |
Two new engines were offered: the base 252-cu. in. 4.1-liter V-6 and the optional 350 diesel V-8 (a converted gasoline engine), which caused owners and GM many problems. The standard Oldsmobile 307 motor was offered for the first time. It gave good gas mileage but slow performance. The T-Type continued with the 3.8 turbocharged V-6, but the other engines could also be ordered. |

The big new option was the Concert Sound six-speaker stereo system and electronic climate control. Gone was the '79-'80 digital trip monitor system.
Total production was 52,007, with only 11,793 V-6s for the model year, and 3,990 T-Type turbocharged V-6s. Diesel production was 16.1%, at 8,372, and not sold in California. Cruise was installed in 95.4%, or 49,596 of the 1981 Rivieras, and vinyl roofs increased to 76.5% of production, 39,775 total.
Prices were increased for 1981, with the standard model starting at $12,523, and the T-Type at $13,499. Production was up despite the higher prices, at 52,007 units. The changes in 1981 were a milestone in the Riviera line and a predictor of continuing change. |
