Enzo Ferrari chased victories in racing, and for that, he developed an upgraded version for the 166 model named 195 Sport and built it in two versions with a closed or an open top. Even though they were not completely new vehicles, since they were converted from the existing 166 models, Ferrari's four vehicles raced and won prestigious races from that era such as Giro dela Callabria, a class-win at the first 6 Hours of Sebring and the 1950 Mille Miglia race. The 159 Sport featured a curved hood with front air-intakes for the engine. Its trapezoidal grille with rounded corners was carried over from the 166 model. The round headlights from the front fenders were mounted as low as possible to ensure a better light on foggy weather. From its sides, the raked, split windshield offered the possibility, in the roadster version, to remove half of it and improve the aerodynamic. With a cabin fit for two occupants and a floor-mounted gear-stick, the 159 Sport provided a sporty ambiance. Its five dials were installed in the dash-panel center, with a big tachometer on the right and the speedometer on the left. In the middle, in a round chromed rim, there were the amp-meter, fuel-level, and the coolant temperature dials. A small rearview mirror adorned the top of the dash, right between the windscreens. Under the hood, Ferrari installed a modified version of the 166 engine. The carmaker enlarged the bore and raised the V-12's displacement to 2.3-liter. It paired it with a five-speed manual.
