Buick Grand National Specifications

Buick introduced the Grand National in 1982 as a sportier, more powerful variation of the Regal. The car was named after the Nascar Grand National series of racing. Buick did not make a Grand National in 1983, but the model was reintroduced in 1984 and produced through 1987.

1982

The 1982 Grand National was offered in a two-tone exterior color scheme of light gray and charcoal gray. This vehicle was equipped with a 4.1 liter V6 engine that provided 125 horse power. It also offered the Gran Touring suspension system. The 1982 Grand National is very rare - only 215 were produced.

1984-1985

The 1984 and 1985 Grand Nationals were all black - the paint, bumpers, front air damn, and rear spoiler. The engine on these model years was upgraded to a 3.8 liter V6 turbo which provided 200 horse power. The vehicle used a sequential fuel injection system and the engine had electronic waste gate control. Only 2,000 Grand Nationals were made in 1984, and 2,100 were made in 1985.

1986

The 1986 Grand National also had a 3.8 liter V6 turbo engine, but significant changes were made to this model year to increase performance. An air-to-air intercooler was added, the exhaust system was redesigned, and the manifolds were modified. This resulted in a vehicle that had 235 horse power and could go from zero to 60 miles per hour in five seconds. 5,512 Grand Nationals were made in 1986.

1987

In 1987, the horse power of the Grand National was increased to 245 horse power. A special edition Grand National GNX was introduced which had 276 horse power. The '87 Grand National could complete a 1/4 mile lap in 14.23 seconds driving 98 miles per hour, and the '87 Grand National GNX could complete 1/4 mile lap in 13.43 seconds driving 103 miles per hour. This was the last year of the Grand National and also the most popular. Over 20,000 were sold.
