When people think of fast cars, GM might not always be the first name that comes to mind. However, the American automotive giant has produced some surprisingly quick vehicles over the years. From stylish sedans to sporty coupes, these under-the-radar models showcase GM’s engineering prowess. Let’s explore some forgotten GM cars that delivered speed and performance beyond expectations.
Pontiac G8 GXP
The Pontiac G8 GXP, produced in 2009, was a powerhouse disguised as a family sedan. Under the hood, it boasted a 6.2-liter V8 engine capable of producing 415 horsepower. This model could accelerate from 0 to 60 mph in just 4.5 seconds, making it one of the fastest sedans of its time. Despite its impressive performance, the G8 GXP’s production was short-lived due to Pontiac’s closure.
Enthusiasts often praise the G8 GXP for its balanced handling and refined interior. With a limited production run, it has become a sought-after model for collectors. The G8 GXP remains a testament to Pontiac’s ability to blend performance with practicality.
Chevrolet SS
The Chevrolet SS, produced between 2014 and 2017, was an unassuming four-door sedan with a beastly heart. Equipped with a 6.2-liter LS3 V8 engine, it generated 415 horsepower, enabling a 0 to 60 mph time of around 4.7 seconds. The SS was essentially a rebadged Holden Commodore, bringing Australian performance flair to American roads.
Despite its understated appearance, the Chevrolet SS offered an engaging driving experience with features like magnetic ride control and Brembo brakes. Its lack of flashy branding and limited marketing made it a hidden gem for those in the know, offering impressive performance without the typical muscle car bravado.
Buick GNX
In 1987, Buick released the GNX, a limited-edition version of the Grand National that pushed the boundaries of what a Buick could be. With a turbocharged 3.8-liter V6 engine, the GNX produced 276 horsepower, allowing it to sprint from 0 to 60 mph in under 5 seconds. This made it one of the fastest production cars in America at the time.
The GNX featured modifications from McLaren Performance Technologies and ASC, enhancing its performance and exclusivity. Only 547 units were produced, making it a rare find today. The GNX remains an iconic symbol of ’80s American muscle and a testament to Buick’s performance capabilities.
Oldsmobile 442
The Oldsmobile 442, particularly the models produced during the late 1960s and early 1970s, was a formidable force on the drag strip. With its 455-cubic-inch V8 engine producing up to 370 horsepower, the 442 could achieve impressive acceleration times. It was a key player in the muscle car era, competing with the likes of the Pontiac GTO and Chevrolet Chevelle.
Known for its aggressive styling and powerful engine options, the 442 offered a blend of performance and luxury features, setting it apart from its competitors. Although Oldsmobile is no longer around, the 442’s legacy lives on as a cherished piece of American automotive history.
Cadillac CTS-V
The Cadillac CTS-V has been a performance icon since its debut in 2004. The second generation, produced from 2009 to 2015, was particularly noteworthy with its supercharged 6.2-liter V8 engine producing 556 horsepower. This allowed it to reach 0 to 60 mph in just 3.9 seconds, rivaling many high-end European sports cars.
Despite its luxury brand image, the CTS-V was engineered for speed and agility. It featured a refined suspension system and high-performance brakes, providing both comfort and control. The CTS-V demonstrated that Cadillac could compete on the world stage of performance automobiles.
Chevrolet Cobalt SS
The Chevrolet Cobalt SS, produced between 2005 and 2010, was a compact car with a surprising amount of power. The 2008-2010 models featured a turbocharged 2.0-liter engine producing 260 horsepower, allowing it to go from 0 to 60 mph in 5.5 seconds. This made it one of the fastest front-wheel-drive cars of its time.
The Cobalt SS offered an affordable entry into the world of sporty driving, with a focus on handling and performance. Despite its economy car roots, it earned respect in the tuner community for its potential for modifications and track capability.
Pontiac Solstice GXP
The Pontiac Solstice GXP, produced from 2007 to 2009, was a stylish roadster with a performance edge. Its turbocharged 2.0-liter Ecotec engine delivered 260 horsepower, achieving 0 to 60 mph in just 5.5 seconds. This made it a spirited option for those seeking open-top excitement.
The Solstice GXP was praised for its handling dynamics and distinctive design. While its interior and practicality were limited, the driving experience provided a fun and engaging ride. It remains a unique part of Pontiac’s history, showcasing the brand’s ability to deliver both style and speed.
