Buick Grand National & GNX – Performance from an Economy V-6

The 1962 Buick V-6 was exposed in the February 1962 Motor Trend Magazine

What few may know and few remember, is that the hefty turbo V-6 found in the Buick T Type, Grand National and the amazing GNX started its life as an economy engine developed by chopping two cylinders off of the Buick Aluminum V-8 of 1961-63, casting it iron, and even going so far to not change the throws on the crankshaft to allow for the different firing pulses of a 6 vs. 8.

There was even a time when that trusty block design and casting were sold to Kaiser for the famous Jeep power plant! But the engine and the rights to use it were returned to GM in 1974. As we say – “the rest is history”. If AMC wasn’t willing to sell back the rights to the V-6, who knows whether the GN and GNX would have ever happened. See this sidebar on the history of the 1962-87 V-6.

The Grand National and its big brother performance-wise the GNX were spawned from the Buick Regal, originally introduced as a personal luxury coupe. The Regal was expanded to a full model line, beginning in 1982. To showcase its success in NASCAR racing, from 1982 to 1987, Buick introduced the Buick Regal Grand National, Regal T-Type beginning in 1982.

But the story of the Grand National begins with the first year of the new G-Body Regal, introduced in 1978. In this first year the Regal could be equipped with 3.8 L – 231.3 CID Turbocharged V-6 engine, known as the Regal Sport Coupe. The Regal Sport Coupe also included a handling package with performance tires and sport wheels. Bucket seats and a center console with a T-shifter were optional but available. This performance option was available through 1983.

A major facelift for 1981 gave the Regal a much more aerodynamic profile, helping make it possible for the car to compete on the NASCAR racing circuit. The sloping hood and nose of the car made it the favorite of several NASCAR teams. The car won many races in the 1981 and 1982 seasons – culminating in the NASCAR manufacturers title in both years.

A Road Test of the 1984
Buick Grand National

Few automotive magazines tested the 1984 Buick Grand National, some because the age of the muscle car as we knew it back then seemed past, and others because They thought the day of exciting US made cars was over.

Motor Trend bucked the trend (ironically) and ran a detailed 4-page story and true road test of the car. The captioned the article “This may be the Buick you’d really rather have”, a sardonic take off of the then current Buick Ad: “Wouldn’t you really rather have a Buick?”

Notable in their evaluation of the car were these points:

Looks: “Black is definitely beautiful here-the only remaining brightwork is the grille surround and matte-aluminum ac­ cents on the wheels. The result of all of the trim removal/blackening is a car that looks immediately more modern, incredibly slicker, all of a piece.”

Interior. “The Lear Siegler seats are upholstered in a textured nubby cloth in sand gray with soft, pleated gray leather inserts. The seats, like the rest of the car, are handsome and certainly look the part.”

Handling: “Handling is quite good, particularly when compared with the GN’s ordinary Regal and Regal Limited cousins.

Acceleration: The best of the car is under the turbo lump. It accelerates like no Buick since the GS series of old, and with 300 lb-ft (of torque) it should.
