The Regal GNX, Buick's new high-performance show car, is designed to celebrate the heritage of the Buick "boosted" V-6 engine. The car name "GNX" honors the quickest production car of its day - the limited-build 300-horsepower intercooled and turbocharged 1987 Regal GNX.
Similar to its namesake, the GNX show car combines premium features while delivering significant power, but updated for the 21st century. The GNX show car debuted at the 2000 Specialty Equipment Manufacturers' Association (SEMA) show in Las Vegas.
In contrast with the original GNX, which was turbocharged, the GNX show car features a high-output supercharged V-6. Buick first offered production supercharged engines in 1991. Over the last 10 years Buick has been the world's leading supplier of supercharged automobiles.
"I doubt any auto manufacturer has derived more performance through the technology of supercharging and/or turbocharging the V-6 engine than Buick," said Mark D. Hines, Regal brand manager. Buick ushered in the modern era of mass- produced V-6 engines in 1962 with the Buick Special claiming Motor Trend Magazine's Car of the Year honors.
Engine output for the GNX show car is increased 20 percent over the production Regal GS. The engine delivers 300 horsepower at 5200 rpm and 300
lb-ft of torque at 3600 rpm. Increased power is derived through a custom intercooler, specially built cold airbox induction system, and custom headers which direct exhaust through a stainless steel exhaust system with catalytic converter and a Borla muffler.
The GNX show car has been lowered 1 1/2 inches from the production Regal GS. Custom-made polished aluminum spoked 18-inch HRE wheels and low-profile 255/45ZR16 Michelin performance tires provide a powerful, aggressive stance.
The body incorporates ground effects all around and is finished in a two-tone metalflake Star Black over a Silver Smoke gray lower trim. The effect of the paint scheme represents midnight under a starry sky. A custom body-colored mesh screen grille with monochromatic Buick tri-shield logo completes the look.
A raised, functional integrated hood scoop featuring three operational portholes on each side contribute to the
performance nature of the Regal GNX show car. The GNX's portholes, a Buick original design introduced in the late 1940s, keep the engine compartment cool for the high-performance supercharged 3800 V-6 engine.
The famous Buick porthole theme is extended to the rear of the Regal GNX show car where three polished stainless
exhaust tips exit through a center opening in the rear fascia. A three-inch high rear spoiler and a stainless exhaust heat shield in the fascia surrounding the exhaust tips complete the rear view.
Baer racing brakes provide stopping power.
The steering wheel, door panels, and shift knob and boot are finished in Star Black leather to compliment the exterior paint color of the GNX show car. A monotone Buick tri-shield is embroidered into front and rear seat headrests. The GNX moniker is embroidered into the front floor mats. The instrument panel insert and the driver and front passenger door control panel areas are painted exterior body color. Front and rear seats are trimmed in Star Black and gray leather.
