Narrowest race car ever? 1923 Aston Martin spans 18 inches

Yes, the bodywork of the “Razor Blade” land-speed-record car measures just over a foot-and-a-half at its widest point

The car was developed as part of an effort to seize the one-hour “light car” top-speed record from rival AC Cars (yes, the Cobra folks). It was fitted with a bespoke 55-horsepower twin-overhead-cam four-cylinder hewn from half of an eight-cylinder Grand Prix engine. The powertrain and wind-cheating bodywork together helped get the Razor Blade exceed speeds of 100 mph (160 km/h) but attempts at the overall record were thwarted by the car repeatedly throwing off its front outside tire.

Nevertheless, later in ’23, the narrow-bodied Aston netted a record for quickest one-mile and one-kilometre pass from a standing start; it would spend the rest of the decade, and then two decades more, participating in other various forms of competition.

The car may be narrow, but you’re going to need some fat pockets to park it in your garage: the asking price is a swell £750,000, or about CDN$1.3 million.
