When it comes to classic cars, Buick may not be the first name that springs to mind for speed enthusiasts. However, beneath the refined exteriors of several Buick models lies an unexpected prowess for performance. These vehicles combine luxury with power, often surprising those who underestimate their capabilities. Here’s a closer look at nine Buicks that prove the brand is no stranger to performance excellence.
1987 Buick GNX

The 1987 Buick GNX is often hailed as one of the fastest production cars of its era. With its turbocharged 3.8-liter V6 engine, the GNX boasted 276 horsepower and a remarkable 360 lb-ft of torque. This was enough to propel the car from 0 to 60 mph in just 4.7 seconds, a feat that put it in direct competition with much more expensive sports cars of the time.
Only 547 units were produced, making the GNX a highly sought-after collector’s item today. Its stealthy black exterior and understated design only add to its allure, making it a true sleeper in the world of muscle cars.
1970 Buick GSX

The 1970 Buick GSX was a limited edition performance package for the Buick Gran Sport. Available in Saturn Yellow or Apollo White, the GSX was equipped with a 455 cubic inch V8 engine, capable of producing 360 horsepower and 510 lb-ft of torque. This power made the GSX one of the most formidable muscle cars of its time.
Its distinctive styling, featuring bold stripes and a rear spoiler, signaled its performance potential. The GSX was more than just about straight-line speed; it also came with upgraded suspension and handling features, making it a well-rounded performance machine.
1965 Buick Riviera Gran Sport

In 1965, Buick introduced the Riviera Gran Sport, a performance-oriented version of its luxury coupe. It featured a 425 cubic inch “Super Wildcat” V8 engine that delivered 360 horsepower and 465 lb-ft of torque. The Riviera’s elegant design was matched by impressive performance, offering a balance of luxury and muscle.
The Gran Sport package included dual four-barrel carburetors, a Positraction differential, and an upgraded suspension. This combination made the Riviera Gran Sport not only fast in a straight line but also capable in handling, a rare quality for cars of its size and era.
1971 Buick Centurion

The 1971 Buick Centurion might be better known for its full-size luxury, but the optional 455 cubic inch V8 engine gave it surprising performance credentials. With up to 315 horsepower and a substantial 450 lb-ft of torque, the Centurion had the muscle to back up its imposing presence.
This model year saw the introduction of new emission controls, which affected power ratings across the industry, but the Centurion still managed to offer a compelling blend of comfort and performance. It was a testament to Buick’s ability to integrate power into its luxury offerings seamlessly.
1986 Buick Regal T-Type

Often overshadowed by its successor, the GNX, the 1986 Buick Regal T-Type was nonetheless a formidable performer. Equipped with the same 3.8-liter turbocharged V6 engine as the GNX, the T-Type offered a lighter and slightly less powerful package, but still delivered impressive performance.
The T-Type was a favorite among enthusiasts for its sleeper status, offering a conservative appearance with the heart of a turbocharged beast. It set the stage for the GNX, proving that Buick was serious about performance in the mid-1980s.
1969 Buick Skylark GS 400

The 1969 Buick Skylark GS 400 was a more performance-focused variant of the popular Skylark model. It featured a 400 cubic inch V8 engine that delivered 340 horsepower and 440 lb-ft of torque, making it a contender in the muscle car segment.
Its combination of power and relatively understated styling made the GS 400 a sleeper hit among muscle car enthusiasts. The availability of the Stage 1 performance package further enhanced its performance credentials, solidifying its place in Buick’s performance history.
1973 Buick Century Gran Sport Stage 1

The 1973 Buick Century Gran Sport Stage 1 was a rare gem in the waning era of muscle cars. This model came equipped with a 455 cubic inch V8 engine, producing 270 horsepower and 390 lb-ft of torque, impressive numbers given the tightening emission regulations at the time.
Despite being on the cusp of the oil crisis and stricter emissions standards, the Century Gran Sport Stage 1 offered enthusiasts a taste of classic muscle car performance. Its combination of power and luxury made it a unique offering in the Buick lineup.
1985 Buick Somerset Regal

The 1985 Buick Somerset Regal might not scream performance at first glance, but it offered a surprisingly engaging driving experience. While it didn’t boast a massive V8 under the hood, this compact model was equipped with a spirited V6 engine that provided a nimble and responsive ride.
Its lightweight construction and compact size made it more agile than many expected, offering a balance of economy and performance. The Somerset Regal was a departure from Buick’s traditional large luxury cars, showcasing the brand’s versatility.
1997 Buick Regal GS

The 1997 Buick Regal GS marked a return to performance for the brand in the late 1990s. Under the hood, the supercharged 3.8-liter V6 engine delivered 240 horsepower and 280 lb-ft of torque. This power allowed the Regal GS to accelerate from 0 to 60 mph in just over 6 seconds.
The Regal GS combined Buick’s trademark comfort with unexpected speed, making it a favorite among those seeking a performance-oriented sedan. It proved that Buick could still deliver excitement and power, even as the automotive landscape shifted towards more efficient and practical vehicles.
