A team was assembled in Indianapolis to build the LSR car. What emerged on 12 February 1928 was the Stutz Black Hawk Special—a comparatively small streamlined car powered by a 180.4 cu in (2.96 L) Miller V-16 (more accurately a U-16) engine with intercooled twin superchargers. The intercooler was formed into the engine cover, allowing air flowing over the car’s body to cool the air/fuel mixture before it entered the engine. The car was made up of a central body, with each wheel housed in its own streamlined fairing. The Black Hawk was perhaps the first car to be designed with the aid of a wind tunnel. Scale models were tested in both the Curtiss and the Army Air Services wind tunnels. Reportedly, the car’s wind resistance was measured as .0061 lb/mph². The Black Hawk was 15 ft 9 in (4.80 m) long with a 112 in (2.84 m) wheelbase. The body was only 24 in (0.61 m) wide, and the car’s total width including the wheels was around 60 in (1.52 m).
