On This Day In 1927, Sunbeam's "Slug" Broke The 200 MPH Barrier

Lots of cars these days can hit 200 miles-per-hour. It’s not nothing, but it’s not anything either. But back in 1927, 200 was unheard-of. That is, Until Sunbeam’s “Slug” broke the record at Daytona Beach with Major Henry Seagrave behind the wheel.

Wolverhampton, England-based Sunbeam is probably a lot more familiar to you all as the builders of cheerful little sportscars like the Alpine and the Tiger, which the company built before eventually getting wrapped into Chrylser Europe’s demise and absorption into Peugeot. But before the brand got pigeon-holed into building small cars with a little more pep than usual, it was trying to make land speed records.

Starting off with the Sunbeam 350HP, the company put some of its airplane engines onto simple frames to try and stretch the limits of what land vehicles could do. In speed maniac Malcolm Campbell’s hands, the 350 HP, which had become the fourth in Campbell’s line of Blue Bird record cars, hit 152 MPH in 1924. But that wasn’t enough for Sunbeam. And that’s where this car came in.
