Alfa Romeo’s most potent engine right now is the turbocharged 1.75-liter four-cylinder that’s fitted to the 2015 4C sports car, where it rates in at 237 horsepower. However, the automaker is reportedly working on new, more powerful engines that are set to start appearing with the arrival of the highly-anticipated replacement for the 159 small sedan, due next summer.  

Sources have revealed to Automotive News (subscription required) that the new engines will come in both gasoline and diesel flavors, and feature four-cylinder and V-6 formats. The most potent will reportedly produce as much as 480 hp thanks to a twin-turbocharging system and direct fuel injection. This unit will likely be reserved for the high-performance version of the Alfa sedan, tipped to wear a GTA badge.

The gasoline units are said to come in 2.0-liter four-cylinder and 2.9-liter V-6 formats. The latter is said to based on the design of the 3.0-liter V-6 used by Maserati; like the Maserati unit, whose highest rating is currently 404 hp, the new Alfa engine may also end up being built by Ferrari.  

As for the 2.0-liter four, this engine is expected to be the volume unit. It’s referred to as the Global Medium Engine and is being developed to produce between 180 and 330 hp. It too will likely benefit from turbocharging and direct-injection technologies to boost output while reducing emissions.

The diesel engines will consist of 2.2-liter four-cylinder units and 3.0-liter V-6 units, all of them turbocharged. The four-cylinder diesels should develop between 135 and 210 hp, while the V-6 should offer between 275 and 340 hp. The V-6 is said to be a variation of the 3.0-liter V-6 diesel currently fitted in some Jeep and Maserati models.  

Beyond the new small sedan, the new engines will eventually appear in several other Alfa Romeo models confirmed to arrive before the end of 2018. These will include two compact cars, another variant of the small sedan (possibly a wagon), a range-topping mid-size sedan, two crossovers (small and mid-size) and a new sports car to replace the 4C.
