Agnelli led the company until his death in 1945, while Vittorio Valletta administered the firm's daily activities. Its first car, the 3 ½ CV (of which only 24 copies were built, all bodied by Alessio of Turin) was based on a design purchased from Ceirano GB & C and had a 697 cc (42.5 cu in) boxer twin engine. In 1903, Fiat produced its first truck. In 1908, the first Fiat was exported to the US. That same year, the first Fiat aircraft engine was produced. Also around the same time, Fiat taxis became popular in Europe.
