Power-to-weight ratio is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance.
A grand tourer (GT) is a type of sports car that is designed for high speed and long-distance driving, due to a combination of performance and luxury attributes. The most common format is a front-engine, rear-wheel-drive two-door coupé with either a two-seat or a 2+2 arrangement. Grand tourers are most often the coupé derivative of luxury saloons or sedans.

The 4CL was introduced at the beginning of the 1939 season, as a rival to the Alfa Romeo 158 and various ERA models in the voiturette class of international Grand Prix motor racing. Although racing ceased during World War II, the 4CL was one of the front running models at the resumption of racing in the late 1940s. Experiments with two-stage supercharging and tubular chassis construction eventually led to the introduction of the revised 4CLT model in 1948. The 4CLT was steadily upgraded and updated over the following two years, resulting in the ultimate 4CLT/50 model, introduced for the inaugural year of the Formula One World Championship in 1950. In the immediate post-war period, and the first two years of the Formula One category, the 4CLT was the car of choice for many privateer entrants, leading to numerous examples being involved in most races during this period.
