We've been lucky enough to see a restored 1953 General Motors Futurliner in person on several occasions, but we've never been able to catch one in action. That said, the folks at Hemmings managed to catch one make a pass down a quarter-mile drag strip.
The result? The behemoth needs a whopping 41 seconds to reach the finish line, where it's then traveling at a blistering 29 mph. Sure, that sounds hilariously pedantic -- but when you take into consideration the physics involved, it's mildly respectable.
Each of the 12 Futurliners built measured in at 33 feet long, 8 feet wide, 12 feet tall, and weighed in at 30,000 pounds. That's a lot of mass to move, especially considering the 1953 variants used a GMC 302 cubic-inch I-6 -- good for a scant 145 hp -- for propulsion.
