Basically everyone in the automotive world is now aware of the Alfa Romeo Giulia by now. It’s a hot new rear-wheel drive Italian sedan that can be had with a Ferrari-derived V-6. However, there’s another engine being launched in the Giulia that may prove more interesting than the 505 horsepower beast, and that’s the new 2.2-liter MultiJet diesel.

Tracing back through history, most modern Fiat MultiJet diesel engines were developed by a Fiat-GM Powertrain, a subsidiary jointly owned by the two automakers. Since their attempt to merge failed rather miserably, some of the diesel engine technology still propagates through the two firms, including this new Alfa diesel.

The novelty of this 2.2-liter is that it features an aluminum block. This is a departure from the other 2.2-liter diesel used by FCA in products such as the Jeep Cherokee. The aluminum construction solves the usual weight problem with diesel engines, with this one weighing in at just over 330-pounds. To put that into comparison, that is similar to the weight of FCA’s Pentastar V-6 engine.

Thanks in part to a variable geometry turbocharger, this engine tops out at 180 horsepower and about 330 pound-feet of torque in the Alfa. Initial reviews of the Giulia with the new diesel in Europe are mostly positive in relation to the car’s power and dynamics. However, the reviews have noted that the diesel is not necessarily as quiet as one expects from a modern diesel. This news comes despite the fact the engine has a balance shaft in an effort to reduce NVH.

Regardless, the question now is rather or not this new mill will make its way into other FCA products. More specifically, it would seem this is a more than appropriate engine for the upcoming 2018 Jeep Wrangler, which is due out in 2017. Rumors have surfaced that a diesel version of the iconic off-roader may be in the cards for the North American market.
