8 Of The Greatest Buick Muscle Cars You Never Knew About

For its final year, Buick offered the Grand National in special GNX form, which stood for Grand National Experimental. Co-developed with McLaren Performance Technologies, only 547 were built, with McLaren returning them with a claimed 276 hp and 360 lb-ft, which was really closer to 300 hp and 420 lb-ft. It was the “Grand National to end all Grand Nationals” and came to define Buick performance for generations. It had an upgraded turbo with a ceramic impeller, a special exhaust, and a Hydramatic 200-4R transmission with a custom torque converter.

It was styled to look the part with an all-black exterior, front fender vents, 16-inch black mesh-style wheels, and an emblem delete kit. Inside, Stewart-Warner analog gauges and a serial number dash plaque were some of the unique upgrades.

It was a monster, and it could outdrag a Ferrari F40 and Porsche 930, clocking a 12.7-second quarter mile and hitting 60 mph in 4.6 seconds.

To this day, the GNX is considered one of Buick’s finest moments and a true collector car that sells for supercar money.
