About the GNX:
For the final year, 1987, Buick introduced the limited production
GNX, for "Grand National Experimental", at $29,900.
Made in partnership with McLaren Performance Technologies/ASC,
Buick produced only 547 GNs with the interior trim package, that
were then sent off to McLaren and upgraded into the Buick GNX.
Buick underrated the GNX at 276 HP at 4400 rpm and a very
substantial 360 lb�ft at 3000 rpm of torque, although actual output
is 300 HP and 420 lb�ft.
This was created to be the "Grand National to end all Grand
Nationals." Changes made included a special Garrett AiResearch 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 EEPROM, 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 Stewart-Warner analog gauges,
including an analog turbo boost gauge.
Performance was measured faster than the Ferrari F40 and the
Porsche 930 with a 1/4 mile time of 12.7 seconds at 113.1 mph and a
0-60 mph time of 4.6 seconds (0.4 and 0.3 seconds quicker,
respectively). 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.
GNX #001 is the 1986 prototype currently owned by Buick and
sometimes makes appearances at car shows around the US.
The stealthy appearance of the all-black GNX and Grand National
(and the resemblance of its grill to his helmet's mouthpiece),
coupled with the fact that the Grand National was initially
released during the popularity of Star Wars movies, earned it the
title "Darth Vader's Car". Car and Driver covered the GNX model's
introduction with the headline "Lord Vader, your car is ready." Due
to the turbocharged six-cylinder engine, the Buick make, and the
black paint Grand Nationals were sometimes referred to as the "Dark
Side". The "Dark Side" contrasted with the more common V8 Mustangs
and Camaros that were popular at the time.
