GMP 1:18 1986 Buick Grand National, Black

The Buick Regal is an upscale mid-sized car that was first introduced by Buick for the 1973 model year. The model was originally positioned as a personal luxury car, and typically offered in both coupe and sedan forms until 1997, when the Regal became sedan-only due to the decline of the personal luxury coupe market. For certain model years between 1973 and 2004, the Regal shared bodies and powertrains with the similar Buick Century, although the Regal was positioned as a more upmarket vehicle

For 1984, the Grand National returned, now in all black paint. The turbocharged 3,791 cc (3.8 L; 231.3 cu in) became standard and was refined with sequential fuel injection, distributor-less computer-controlled ignition, and boasted 200 hp (203 PS; 149 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 2,000 of which were Grand Nationals. Because this was the first year of production of the computer-controlled sequential fuel injection and distributor-less ignition, this is often considered the year and 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 kept up with the bigger V8s. 1⁄4 mile (402 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 V6 was listed at 17.0 and the Chevrolet Corvette at 15.2 seconds. Soon, performance enthusiasts determined the modifications that worked and the Grand Nationals easily broke into the 13-second territory. All Grand Nationals had the Lear Siegler-made cloth/leather interior which was only available for this year. An estimated 200 of the 1984 Grand Nationals were produced with the T-Top option which makes these the rarest of the Grand Nationals.

For 1986, a modified engine design with air-air intercooling boosted the performance even further to a specified 235 hp (238 PS; 175 kW) at 4000 rpm and 330 lb⋅ft (447 N⋅m) of torque at 2400 rpm. The Grand Nationals (quantity 5,512) and T-Types (quantity 2,384) were both produced in 1986. For 1987, performance reached 245 hp (248 PS; 183 kW) and 355 lb⋅ft (481 N⋅m) of torque. Buick dropped the T-Type package for Regal for 1987 models and opted for a "T" sport package instead. 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 "1987½ Buick Grand National" vehicles.
