The XP-300 is particularly noted for its influence on the styling and technology of the 1950s and beyond, making it a cherished example of mid-20th-century automotive innovation.
The Buick V-8 engine – nicknamed Nailhead for its unique valve arrangement – was introduced in 1953 and powered the Wildcat concept vehicle a year later. Using a quartet of sidedraft carburetors, engineers coaxed 10 percent more horsepower from the engine than regular-production models, giving the Wildcat the power to back up its sporty styling.
The 1954 Buick Wildcat was a concept car that represented Buick’s bold vision for the future of automotive design and technology. As part of Buick’s series of Wildcat concept cars, the 1954 model showcased innovative features and styling cues that influenced the brand’s production vehicles.

The use of fiberglass for the body construction, the sleek and aerodynamic design, and the luxurious interior features were ahead of their time and demonstrated Buick’s forward-thinking approach.
The 1954 Wildcat remains a significant piece of automotive history, highlighting the creativity and engineering prowess of Buick during the mid-20th century. It is celebrated by car enthusiasts and collectors for its unique design and the vision it represented for the future of automotive design.
Developed for and debuted at the 1956 Motorama, the Buick Centurion’s futuristic design has been beloved for decades. With many features considered “new” today, this car was certainly ahead of its time. Buick enthusiasts will recognize the “sweep-spear” chrome on the Centurion as being similar to the 1957 Buicks. They might even recognize the rear fins as being like those on the 1959 models. The rest of the car, however, is one of a kind.
The Centurion uses a freestanding speedometer, with a fixed indicator and rotation dial. A television camera, mounted just above the tail cone, projects images from the rear of the car to a screen on the dash, thus eliminating the need for a rear view mirror. Centurion’s “wings,” tail cone, and canopy top reflect the influence that aircraft design had on many of GM’s designers.
