1995 Buick Rivera Commercial
After a hiatus in 1994, the Riviera returned in 1995 with radical styling that departed from the previous generations' traditional image. A 205 hp (153 kW) naturally aspirated 3800 V6 was standard, with a supercharged version rated at 225 hp (168 kW) and 275 lb-ft (373 N⋅m) available as an option. Rivieras were now built-in Orion Township, Michigan, riding the same Cadillac-derived G platform as the 4-door Oldsmobile Aurora. The first of 41,422 Rivieras made in 1995 rolled off the assembly line on May 23, 1994.
In 1996, supercharged versions saw an increase in power to 240 hp (179 kW) and 280 lb·ft (380 N·m), as well as the 4T60E-HD transmission. 18,036 Rivieras were manufactured in 1996.
1997 saw suspension revisions, removing excess weight. An upgraded 4T65E-HD transmission featuring a larger 258 mm (10.2 in) torque converter and heavy-duty gearbox were added. 18,827 were made in 1997.
For 1998, the 240 hp (180 kW) supercharged V6 became standard. GM's OnStar service was added as an option, along with minor interior design changes and features including passenger heated seats. A total of 10,953 units were produced for 1998.
With sales of all coupes declining in the North American market, GM decided to discontinue the Riviera. 1999 was the car's last model year with production of 1,956 cars ceasing on November 25, 1998. The final 200 cars had special silver paint and trim and were denoted "Silver Arrow" models, a designation which hearkened back to several Silver Arrow show cars that had been built off Riviera bodies by Bill Mitchell.
Eighth-generation Rivieras received the most powerful V6 Buick engine since the Grand Nationals of the 1980s. The supercharged OHV V6 provided high torque and acceleration allowing 0 to 60 miles per hour (97 km/h) in under 7 seconds and turning the 1⁄4 mile in 15.5 seconds. Supercharged Rivieras achieved a fuel efficiency figure of 18/27 (city/highway mpg).
