Fiat JTD engine

Multijet is Stellantis's term for its current common rail direct injection turbodiesel engine range. Most of the Fiat, Alfa Romeo, and Lancia range, as well as certain Chrysler, RAM Trucks, Jeep, and Maserati vehicles, are equipped with Multijet engines. Ownership of some Fiat Multijet designs is shared with General Motors as part of a settlement of the failed merger between the two auto conglomerates. The GM Powertrain Torino group in Turin, Italy, manages its interest in these engines. Some PSA Peugeot Citroën diesel engines are also rebadged JTD units, and vice versa. Fiat's common-rail diesel engine is also known as JTD, an initialism of Jet Turbo Diesel.
