Raw Power!

At the heart of the Buick Grand National is a beastly powertrain that left its rivals in the dust. The most iconic variant, the GNX, featured a turbocharged 3.8-liter V6 engine that churned out an impressive 276 horsepower and a staggering 360 lb-ft of torque. These figures were exceptional for the era and propelled the Grand National to be one of the fastest American production cars of its time.

Performance Stats

Thanks to its potent engine, the Grand National delivered an exhilarating performance on the road. Accelerating from 0 to 60 mph took just around 5.5 seconds, while the quarter-mile sprint was accomplished in approximately 13.5 seconds, putting the Grand National in the same league as high-performance sports cars of its day.

Timeless Style

The Buick Grand National featured a sinister and aggressive design that turned heads wherever it went. Ditching chrome accents in favor of a stealthy all-black appearance, the Grand National exuded an air of understated menace. Its sleek body lines, flared wheel arches, and iconic “Power 6” badge on the front fenders added to its aura of mystique.

Limited Edition GNX

The pinnacle of Buick Grand Nationals was the GNX, of which only 547 were ever produced. The GNX was a collaboration between Buick and ASC/McLaren, resulting in an even more formidable performance machine.

The Grand National’s robust engine and aerodynamic design made it a formidable contender on the track, further solidifying its reputation as a performance-oriented machine.

Due to its limited production numbers and cult-like following, the Buick Grand National has become a highly sought-after collector’s item. The combination of its unique styling, exceptional performance, and historical significance has made it a prized possession for car enthusiasts and collectors worldwide. Today, well-preserved Grand Nationals, particularly the GNX models, command high prices in the collector car market.
