Anonymous sources at suppliers are already making some big claims about the new mills to Automotive News Europe. The top of the heap is reportedly a 2.9-liter, twin-turbocharged V6 making up to 480 hp, based on the 3.0-liter engine in the Maserati Quattroporte and Ghibli. Below it is a turbocharged 2.0-liter four-cylinder that's claimed to produce between 180 hp and 330 hp for rear- or all-wheel drive applications. Finally, there's potentially a 2.2-liter turbo-diesel four with between 135 hp and 210 hp.
Little has been officially announced about the midsize sedan, but it was possibly spied testing recently hidden under the body of a Ghibli. It was rumored to be rear-wheel drive with a size between the BMW 3 Series and 5 Series, and a high-performance GTA version was also speculated. According to ANE, the vehicle won't be called the Giulia and won't hit the market in the US until 2016.
In addition to the midsize model's engines, FCA is also reportedly working on an updated version of its 3.0-liter diesel V6 sourced from VM Motori with new 275-hp and 340-hp versions. They are likely slated for Alfa's future large sedan and SUV.
