Buick Built the Blandest Sedan of the 1980s — Then Turned It Into a Dragstrip Legend Kendrick Lamar Named an Album After

Buick’s turbocharged Grand National looked like an ordinary 1980s Regal — until its GNX variant became dragstrip legend. In 2024, Kendrick Lamar named an album after it. Here’s the real story behind the numbers.

Buick spent most of the 1980s building sensible, forgettable sedans for buyers who wanted beige interiors and a quiet ride to the grocery store. Then the division built a turbocharged black Regal so quick off the line that it became the stuff of dragstrip legend — a car enthusiasts swore could embarrass exotics costing five times as much. By 1987, the ultimate version of that car, the GNX, was so capable that GM’s own published numbers undersold what it had actually built. Decades later, a Compton-born rapper would name an entire album after it, dragging a 37-year-old Regal variant into a cultural conversation Buick never could have predicted. This is the story of how the most boring badge in Detroit built one of the fastest cars in America.

A Doug DeMuro Deep Dive Into Buick’s Black Sheep

In a detailed walkaround review, YouTuber Doug DeMuro puts a 1987 Buick Grand National through his signature format — cataloging the car’s quirks and features before getting behind the wheel. DeMuro treats the Grand National the way he treats most cult classics: with genuine curiosity about why a car this understated became this famous, and why GM let a mid-size Regal coupe quietly become one of the quickest domestic cars money could buy for a few model years in the 1980s.

The review spends real time on the Grand National’s interior, from its monochrome black-on-black trim to the turbo boost gauge mounted front and center on the dash — a detail GM added specifically because the car’s turbocharged V6 made boost pressure something owners actually wanted to watch. DeMuro also walks through the driving experience, noting how unassuming the car feels at idle right up until the turbo spools up and the Grand National reveals what it was actually built to do.

A Name Borrowed From NASCAR’s Biggest Stage

The Grand National name didn’t come from a marketing department brainstorm — it came straight off the racetrack. Buick dominated NASCAR’s premier stock car division in the early 1980s, with driver Darrell Waltrip winning back-to-back championships in 1981 and 1982 behind the wheel of a Buick Regal, and the brand claiming the Manufacturers Cup both years. Buick wanted to capitalize on that success, so when it launched a special Regal coupe in February 1982, it borrowed the name directly from NASCAR’s Grand National Series.

That first Grand National was a modest affair: a naturally aspirated V6 making roughly 125 horsepower, wrapped in a two-tone paint scheme, with just 215 units built. Buick skipped the model entirely in 1983. The transformation that made the Grand National famous didn’t begin until 1984, when Buick swapped in a turbocharged 3.8-liter V6 and started chasing real performance instead of just racing nostalgia.

Why a Turbo Six Instead of a Big-Block V8

The Grand National’s turbo V6 wasn’t a performance-first choice — it was born out of necessity. New federal Corporate Average Fuel Economy rules in the 1970s pushed Buick away from thirsty V8s and toward a smaller, lighter six-cylinder architecture the brand had reacquired the tooling for back in 1974. For years that engine was neither smooth nor particularly powerful. What changed everything was the combination of turbocharging, electronic fuel injection, and an intercooler, added through the mid-1980s, which let Buick meet emissions and economy targets while still building an engine that could embarrass V8-powered muscle cars at the dragstrip. The Grand National became proof that a government mandate aimed at slowing cars down could, in the right hands, build one of the quickest cars of the decade instead.

By 1987, the final and most powerful year of the model, Buick built roughly 20,193 Grand Nationals, officially rated at 245 horsepower and 355 lb-ft of torque — figures widely considered conservative even at the time. That same year, Buick partnered with American Specialty Cars (ASC) and McLaren Performance Technologies to build something meaner: the GNX. Just 547 cars with Grand National interiors were pulled aside and sent through the ASC/McLaren conversion, which added a Garrett T3 turbocharger with a ceramic impeller, a larger intercooler, reworked engine management, a stiffened suspension, and a unique rear differential cover.

GM officially rated the GNX at 276 horsepower and 360 lb-ft of torque — numbers that period dyno tests and several outlets have since put closer to 300 horsepower in reality. Buick’s own literature claimed the GNX would hit 60 mph in 5.7 seconds and clear the quarter-mile in 14 seconds. Independent testers who got their hands on one in period ran it considerably quicker, into the low 13-second range in the quarter-mile — fast enough that the car has been the subject of enduring dragstrip lore ever since, including period comparisons to exotics that cost many multiples of its $29,900 sticker price (itself nearly double the $15,136 asked for a 1986 Grand National).

That’s also why the Grand National’s badge-engineering story resonates with collectors who normally skip past Buick entirely. This wasn’t a flagship built with unlimited budget and a blank check from corporate — it was a mid-size Regal that Buick’s engineers kept quietly sharpening year after year until it outran cars twice its price. The GNX, in particular, stands as proof that the right turbocharger and the right small team can do more for a car’s reputation than a bigger engine ever could.

The Album That Introduced the GNX to a Whole New Generation

For decades, the Grand National and its GNX variant lived almost entirely inside car-collector circles — prized by enthusiasts, largely unknown outside them. That changed in 2024, when Kendrick Lamar titled his surprise album GNX directly after the Buick. Lamar has said he came home from the hospital as a newborn in an ’87 Buick Regal, the same model year the GNX was built in, and the album’s cover shows him leaning against the trunk of the car. A representative for his label confirmed the title was a direct reference to the Buick, not a stylized acronym invented for the project.

The connection turned a 37-year-old Regal variant into a trending search term almost overnight, and comment sections on decades-old Grand National reviews filled with new viewers discovering the car for the first time because of a rap album rather than a car magazine. It’s a strange second act for a car Buick built to quietly outrun expectations — the GNX was always a car designed to surprise people who underestimated it, and in 2024 it did exactly that to an entirely new audience.

What to Know If You Want One Today

Part of the Grand National’s lasting appeal is how little it looks the part. There’s no scoop-covered hood or loud graphics package — just a blacked-out Regal coupe that happened to house one of the quickest factory drivetrains GM sold that decade. That restraint is exactly why collectors chase them now: values for well-kept Grand Nationals and GNXs have climbed steadily, with a GNX selling at Mecum for just over $105,000 as far back as 2014, and concours-grade examples now valued well into six figures by collector-car insurers.

Anyone shopping for one today should treat the turbo 3.8-liter V6 and its period-correct Garrett turbocharger as the car’s most important — and most expensive to get wrong — component. Originality matters enormously to value, so a verified GNX build sheet, matching numbers, and documentation from the ASC/McLaren conversion are worth far more than a Grand National that’s simply been dressed up to look like one. With 547 real GNXs built in a single model year, surviving examples are scattered, closely tracked by their owners, and rarely offered for sale — which is exactly why a rap album in 2024 was enough to send an entirely new generation looking for one.
