One such experimental car, the XP-300, featured a futuristic name reflecting its unusual design and light, sleek body made of heat-treated aluminum. Seen here during a test drive at the Orange County Airport in Santa Ana, this Buick boasted a 300-horsepower, supercharged V8 engine and reached a top speed of 140 miles per hour. Its 6.5 inches of ground clearance typified the “long and low” look GM promoted in the 1950s.
