About Buick Regal Grand National
With a spirit that resembled the muscles cars from a decade or two before, the Buick Regal Grand National was all about speed, even getting its name from the NASCAR championship of the day. As the name suggests, the Grand National is basically a Buick Regal that has been supersized. Beginning in 1982, and then returning from 1984 to 1987, the Grand National began life with a 253-cubic inch, 4.1-liter Buick V6 engine mated to a three- or four-speed THM200 automatic transmission or three-speed manual transmission that achieves 125 horsepower at 4,000 revolutions per minute and 205 lb-ft of torque at 2,000 rpms. A few 1982 Grand Nationals come with a turbocharged 231ci, 3.8-liter V6 engine capable of 175 hp at 4,000 rpm and 275 lb-ft of torque at 2,600 rpm. After a year's hiatus, the Grand National returned in its signature all-black paint and the turbocharged engine as standard equipment. Retrofitted with a sequential fuel injection system, the horsepower increased to 200. By the end of the run, modification allowed the Buick Grand National Turbo engine to achieve 235 hp and 355 lb-ft of torque. Style-wise, the Grand National was a first cousin to the Regal, with only minor interior and exterior modifications. Still visible on the road today, Buick Regal Grand Nationals are part of the large inventory of cars available on eBay. Also available for fans of the car are Buick Grand National die-cast cars of varying scale, including 1/18 and 1/64.
