In 1984 the Grand National name was revived on the turbo Regal, all black, with a 3.8 litre V6 (engine code LM9) rated 200 hp and 300 lb-ft, using sequential fuel injection, distributorless ignition and an electronic wastegate. Of 5,204 turbo Regals built that year, about 2,000 were Grand Nationals.
The quarter-mile was listed at 15.9 s at stock boost of 10 psi. About 200 had the Astroroof option.
