The model year 1987 holds a truly hallowed status in the annals of American muscle car history, largely due to the concluding production year of the Buick legendary rear-wheel-drive G-platform Regal coupe. This was a time which witnessed the apex of a surprising performance revival, establishing a clear pecking order of that spanned the understated performers all the way to a all-out asphalt destroyer. Although they all were based upon the same basic chassis, the Buick Regal Limited, the Turbo T, the Grand National, as well as the mythical GNX each had a distinct personality, set of of specifications, and intended buyer. Understanding the subtle and not-so-subtle differences is key to truly grasping the genius behind Buick's final last performance stand of the 1980s.
The Foundation of Force: The Regal Limited and Turbo T
At the foundational bottom of this power pyramid sat the surprisingly flexible often frequently underappreciated variants: the Regal Limited with the turbo engine and the Turbo T-Type. The Regal Limited was primarily traditionally the brand's comfort-focused package, replete with plush seating, ample brightwork trim, and a compliant suspension. However, for that final year, astute customers could discreetly spec this luxurious plush coupe the addition of the potent powerful LC2 3.8-liter V6 intercooled powertrain, effectively birthing a true predator in sheep's clothing. This allowed for a a stealthy high-performance experience without the aggressive overtly aggressive styling of more famous blacked-out siblings.
Conversely, the Turbo T, often known its its WE4 RPO code, represented a more more focused philosophy to lightweight performance. Buick designed the Turbo T as a more agile counterpart for the heavier Grand National, attaining this through utilizing lightweight aluminum bumper reinforcements and aluminum wheels. Visually, it was in direct opposition the all-black Grand National, retaining most of the factory brightwork trim and being offered in a wide spectrum factory exterior colors. This was the purist's choice for those that valued unfiltered performance and a more responsive feel over the iconic unmistakable style presence of more famous better-known infamous all-black counterpart.
The Dark Icon: The Grand National (WE2)
When many people envision a 1980s Buick muscle vehicle, the image vision which instantly springs to mind is the the menacing Grand National. Designated as the WE2 Regular Regular Production Production Option (RPO), the '87 Grand National was not so much of a mechanically separate model but rather an all-encompassing iconic styling and trim package. This model shared the identical same powerful LC2 3.8L intercooled V6 and 200-4R automatic transmission found in the Turbo T. But, its unmistakable trait was its monochromatic all-black exterior scheme, a look that earned it the famous nickname "Darth Vader's car" and "the Dark Side."
This sinister sinister aesthetic was meticulously enforced across the entire entire car. All of the the body molding, including the window surrounds and the grille grille, was blacked-out. The vehicle rode upon specific fifteen-inch steel steel wheels with a contrasting black-painted center section, creating a truly very distinctive look. On the interior, the Grand National featured a specific dual-color black and gray cloth upholstery, with the turbo six logo embroidered into the front front headrests. The model also was equipped with the stiffer F41 Gran Gran Touring suspension, which provided the vehicle sharper handling to match its impressive accelerative performance.
The Apex Predator: The Grand National Experimental (GNX)
While the Grand National was the king of the street, the GNX GNX was nothing less than the pinnacle of American domestic muscle cars of 1987. Developed as a a final farewell to the Regal chassis, Buick sent just five hundred forty-seven fully-optioned optioned Grand Nationals the facilities of ASC/McLaren a a comprehensive re-engineering. The goal objective was simple simple: to create the "Grand "Grand National|Grand National} to end all Grand Nationals." The outcome was a machine machine which was so so fast it was able to beat most of the world's day's most expensive supercars, such as Ferraris and Lamborghinis.
The upgrades were extensive highly very impactful. ASC/McLaren installed a more efficient Garrett ceramic-impeller ceramic-impeller turbocharger, a more efficient intercooler, a a custom programmed engine control management unit (ECU). The 200-4R was recalibrated firmer quicker gear changes, critically most importantly, the entire here rear axle setup was completely re-engineered. It included a unique unique ladder bar and a transverse Panhard rod, which dramatically improved traction virtually completely eliminated axle hop during brutal launches. Fully appreciating the complete full Difference between 1987 Buick Regal Limited Turbo T Grand National GNX requires a thorough dive of the engineering that ASC/McLaren invested in this extremely very rare vehicle.
Breaking Down the Specs, Options, and Visual Cues
When analyzing these four models, the differences distinctions in specifications and options are made even more clear. Officially, the LC2 found in the Regal Limited, Turbo T, and Grand National was conservatively conservatively rated at 245 horsepower with 355 pound-feet of torque. By dramatic comparison, the GNX, thanks to its extensive upgrades, was officially pegged at two-hundred and seventy-six horsepower and a staggering staggering three-hundred and sixty lb-ft of torque, although actual dyno readings have repeatedly proven these figures to have been grossly underestimated, the true true output being well above 300 horsepower.
In terms of appearance, the hierarchy was just as defined. The Turbo T the Limited were sleepers of the group, frequently wearing chrome bumpers being available a a wide range of exterior paints. The Grand National, of course, was exclusively black, creating an unmistakable intimidating aura. The GNX, in turn, elevated this menacing theme a step further. It featured lightweight fender flares, functional heat-extracting louvers on the front front fenders, a set of a style of 16-inch black mesh cross-lace rims which set it apart instantly even from even a regular Grand National. Options like removable roof panels were widely ordered on the Limited, Turbo T, but Grand National, however, no GNX was ever officially produced the T-top this feature, in an effort to maintain optimal chassis rigidity.
Summary: A Legendary Hierarchy of Power
In the final analysis, the 1987 Buick Regal lineup represents a masterful case study of product tiering the art of performance evolution. From the surprisingly unexpectedly fast and comfortable Regal Limited and the agile Turbo T, the brand offered a spectrum range of forced-induction power to suit varying tastes and budgets. The Grand Grand National subsequently solidified this power into an unforgettable and intimidating style package, creating a cultural automotive phenomenon which endures even this very day. Crowning this all was the mighty GNX, a limited-edition rare supercar which served as a definitive final statement point, cementing the G-body platform's status within the halls of performance legends. Each model model was special distinct in its own right, but together they formed a unforgettable lineup which defined domestic performance for a a generation.
