JTD, an initialism for uniJet Turbo Diesel, is Fiat Group's term for its current common rail turbodiesel engine range. The MultiJet name is used in the second generation JTD common rail units. Most of the Fiat, Alfa Romeo and Lancia range has JTD engines. Ownership of some Fiat JTD designs is shared with General Motors as part of a settlement of the failed merger between the two auto conglomerates. GM Powertrain Torino group in Turin, Italy manages their interest in these engines. Some PSA Peugeot Citroën diesel engines are also rebadged as JTD.

A new generation JTD engine, Multijet II was introduced in Fiat Punto Evo in 2009.

Italian FNM is marinizing Fiat diesel engines like the four cylinder 1.9 L and five cylinder 2.4 L for boat propulsion, they are producing between 60-295 hp.

A small 1.3 L (1,248 cc) version (called the SDE, Small Diesel Engine) is produced in Bielsko-Biała, Poland and in Ranjangaon, Pune, India by Fiat India Auto. The Multijet 75 PS version was chosen in 2005 as the International Engine of the Year in the 1-litre to 1.4-litre category.

There are four versions of this engine: a 70 PS (51 kW; 69 hp), a 75 PS (55 kW; 74 hp) (used in the Fiat Punto, Panda, Palio / Albea, Fiat Idea, Opel Corsa / Combo, Opel Meriva, Suzuki Ritz, Suzuki Swift), a variable inlet geometry 90 PS (66 kW; 89 hp) (used in the new Fiat Grande Punto, Fiat Linea, Suzuki Ertiga, Opel Corsa, Opel Astra and Alfa Romeo MiTo), and a 105 PS (77 kW; 104 hp) is available to Lancia Ypsilon. At the time of the launch this was the smallest four-cylinder diesel engine available and has a fuel consumption of 3.3 L/100 km (86 mpg_-imp; 71 mpg_-US) in some applications. The engine is able to meet Euro IV pollution standards without the use of a diesel particulate filter.

In January 2008 Tata Motors introduced new Indica Vista model, which features new QuadraJet branded version of this engine. The second generation Ford Ka uses 1.3 Multijet named as Duratorq TDCi .

During 2009 Fiat launched a new generation badged Multijet 2, with a new injection management system (up to 8 injections per cycle, instead of 5) and able to meet Euro V pollution standards. It is available with several power outputs: from 75 PS (55 kW; 74 hp), with fixed geometry turbocharger, to 95 PS (70 kW; 94 hp), with variable geometry turbocharger.
