The Lancia Beta range was developed after Fiat took over at Lancia. The name 'Beta' was chosen to signify the 'start again' idea now that Lancia had come under the control of Fiat, and because 'Alpha' would have been confused with 'Alfa (Romeo)'. The 4-door berlina was launched in 1972 with a Fiat-designed fastback body that did not have a hatchback. The Beta was given a dohc engine from the Fiat 124 Sport, but developed and built by Lancia and came in 1483cc, 1592cc and 1756cc versions, a 1297cc engine was added in 1974 for the Beta 1300, and the 1756cc engine expanded to 1995cc in 1975. Piero Castagnero designed the Beta coupe in house for Lancia in 1973, and this was given sportier versions of the 1592cc and 1756cc engines. The final version of the Beta was the 3-box saloon version called the 'Trevi' and designed by Pininfarina.
