Grand National, T-Type and GNX[edit]

In 1982, the Regal Grand National debuted, which was named for the NASCAR Winston Cup Grand National Series (the "Grand National" term was part of the Cup series nomenclature until 1986). Buick had won the Manufacturers Cup in 1981 and 1982, and wanted to capitalize on its success: "What wins on Sunday, sells on Monday". These 1982 cars were not painted black, which may confuse those not familiar with them. All started out as charcoal gray Regals that were shipped off to a subcontractor for finishing.

Originally intended for a run of 100 units, Cars and Concepts of Brighton, Michigan, retrofitted 215 Regals with the GN package. Most obvious was the light silver gray firemist paint added to each side. Red pinstripes and billboard shadow lettering proclaiming "BUICK" were applied. The wheel opening moldings and rocker panel moldings were blacked out using black vinyl tape. Finally, a front air dam and rear spoiler were installed. On the inside, special "Lear-Siegler" seats were installed. These seats are fully adjustable and were covered with silver brandon cloth with black vinyl inserts. The front seat had Buick's "6" emblem embroidered onto them. To finish it off, a special clock delete plate was added to the instrument panel which contained the yellow and orange "6" logo and the words "GRAND NATIONAL BUICK MOTOR DIVISION."

The '82 GN came with a naturally aspirated 4.1 L V6 engine with 125 hp (93 kW) at 4000 rpm and 205 lb·ft (278 N·m) of torque at 2000 rpm. Of the 215 Regal Grand Nationals produced in 1982, at least 35 were based on the Buick Regal Sport Coupe package with the turbocharged 3.8 V6 engine with 175 hp (130 kW) at 4000 rpm and 275 lb·ft (373 N·m) of torque at 2600 rpm. There were only 2022 Sport Coupes produced in 1982, and the number of cars with both the GN and Sport Coupe packages is estimated to be less than 50.

For 1983, there was no Grand National. The Sport Coupe model was renamed the T-Type; 3732 were produced (190 hp (140 kW) at 1600 rpm and 280 lb·ft (380 N·m) of torque at 2400 rpm). The T-Type had been used on other Buicks, starting with the Riviera in 1981 (in 1979 and 1980, it was the S Type). The 1983 Regal T-Type featured tube headers, Hydro-Boost II brakes, 200-4R 4-speed overdrive trans and 3.42 rear axle (7.5").^[4]

In 1984 the Grand National returned in all black paint. The turbocharged 3.8 L became standard and was refined with sequential fuel injection, distributor-less computer controlled ignition, and boasted 200 hp (150 kW) at 4400 rpm and 300 lb·ft (407 N·m) of torque at 2400 rpm. Only 5,204 Turbo Regals were produced that year, only 2000 of which were Grand Nationals. Because this was the first year production of the computer controlled Sequential Fuel Injection and Distributor-less ignition, this is often considered the year/model that started the development of the legendary intercooled Grand Nationals. The performance of this package was well ahead of its time and the “Little V6” easily matched that of the bigger V8’s. Quarter mile (~400 m) performance was listed at 15.9 seconds at stock boost levels of 10 psi (0.69 bar), while for the same year, the Chevrolet Camaro was listed at 17.0 and the Chevrolet Corvette at 15.1 seconds.^{[citation needed]} Soon, performance enthusiasts determined the modifications that worked and the Grand Nationals easily broke into the 13 second territory. All Grand Nationals for this year had the Lear Siegler-made cloth/leather interior which was only available for this year. An estimated 425 of the 1984 Grand Nationals were produced with the T-Top option which makes these the rarest of the Grand Nationals.

1986 Grand National

In 1986, a modified engine design with intercooling boosted the performance even further; in 1987 it reached 245 hp (183 kW) and 355 lb·ft (481 N·m) of torque. Buick dropped the T-Type package for Regal in 1987. There were only 7,896 Turbo Regals produced in 1986. In 1987, when Turbo Regals reached their peak in popularity, a total of 27,590 Turbo Regals were produced through December, with those models produced between September and December of that year window stickered as "1987 1/2 Buick Grand National" vehicles.

In 1987, a lightweight WE4 (Turbo T) option was offered. Only 1,547 of this variant were produced. They were painted black and treated to the same blackout package as the Grand National, including bumpers, grille, headlight and taillight trim. The differences between a WE4 and the Grand National were the interior trim package, wheels, exterior badging, aluminum bumper supports, and aluminum rear brake drums as opposed to the Grand National's cast iron, making the WE4 a lighter and faster car. The rear spoiler was only available as a dealer installed option. 1987 was the only year that the LC2 Turbo option was available on any Regal, making it possible to even see a Limited with a vinyl landau roof and a power bulge turbo hood. Turbo Regal Limiteds were one of the rarest models of Turbo Regals produced second only to the GNX at 1,035 Turbo Limiteds. Turbo Regal Limiteds could be ordered with many options with most having chrome external trim but for $35 could have been built with the full black-out trim option making them extremely rare. Limiteds were treated to a very luxurious interior with plush carpeting and optional bench pillow seats and a column shift. The 1987 model would be the end of the manufacture of the RWD "G-Body" Regal, but GM had to extend the build of the Grand National to meet customer demand into November.

For the final year, 1987, Buick introduced the Limited Production GNX "Grand National Experimental" at $29,900. Produced by McLaren Performance Technologies/ASC, Buick produced 547 with the Grand National interior trim Package. They were then sent off to McLaren Performance Technologies and upgraded into the Buick GNX. Buick underrated the GNX at 245 hp (183 kW) and a very substantial 360 lb·ft (488 N·m) of torque.^[5] This was created to be the "Grand National to end all Grand Nationals." Changes made included a special Garrett T-3 turbocharger with a ceramic-impeller blowing through a more efficient and significantly larger capacity intercooler with a "CERMATEL (Ceramic/Aluminum) coated" pipe connecting the intercooler to the engine. A GNX specific E-EPROM, low-restriction exhaust with dual mufflers, reprogrammed Turbo Hydramatic 200-4R transmission with a custom torque converter and transmission cooler, and unique differential cover/panhard bar included more of the performance modifications. Exterior styling changes include vents located on each front fender, 16 inch black mesh style wheels with VR-speed rated tires, and deletion of the hood and fender emblems. The interior changes of the GNX included a serial number on the dash plaque and a revised instrument cluster providing analog Stewart-Warner gauges, including an analog turbo boost gauge. Performance was measured with a quarter mile time of 13.2 seconds at 104 mph (167 km/h) and a 0-60 mph (97 km/h) time of 4.3 seconds.^[6] GNX #001 is the 1986 prototype currently owned by Buick and sometimes makes appearances at car shows around the US. The GNX used a unique torque arm that was mounted to a special, GNX only, rear differential cover, for increased traction. The torque arm rear suspension alters the suspension geometry, making the body lift while planting the rear tires down, resulting in increased traction.
