City cars such as the Alfa Mito, Fiat 500 and Opel Corsa were compact to suit their environment so needed an equally compact diesel unit to fit their tiny engine bay; the 1.3 D that Fiat had already developed was the obvious candidate.
The first generation of MultiJet engine was produced in huge quantities, fitted over dozens of manufacturers and models. A class leader, it even won the International Engine of the Year.
In 2009, Fiat reworked the first generation with a new injection system that was capable of delivering 8 injections per combustion cycle at a pressure of 1400 bar (20000 PSI). These upgrades boosted power, and made it more efficient than ever, complying with Euro V emissions standard; which resulted in a further increase in application.
The 1.3 JTD will go down as one of the biggest collaborations amongst manufacturers as used by: Alfa Romeo, Chevrolet, Chrysler, Citroen, Fiat, Ford, Opel, Peugeot and Suzuki. Don’t you just love it when a single part fits 25 models?
