American auto giant FCA might soon bid farewell to its popular V6 engine and instead usher a new inline-6 configuration machine.

A report published by Allpar on Tuesday suggested that a possible straight-six engine was in the works at the company, which would eventually make its way to numerous FCA vehicles in the coming generation.

This development in the automaker’s shed is, however, in contrast to earlier reports which mentioned major upcoming updates to the Pentastar V6 engine. The machine, as we know, was on deck for turbocharging, direct injection, and improved variable valve timing to meet more stringent fuel economy regulations.

However, contrary to this, FCA has allegedly transformed the Pentastar into an inline-six reportedly due to packaging and size benefits. Reports citing internal sources suggest that the company was targeting for a length not more than 3-inches longer than the current 3.4-litre inline-4 engine. As far as the power is concerned, we expect that the new engine will reportedly displace less than 3.0-litres to avoid additional taxes in global markets. However, we expect the power to rival the 5.7-litre Hemi V8 engine, thanks to the turbocharging.

Reports suggest that the turbos are likely to be single twin-scroll units for FCA’s common brands, while twin turbos could grace Alfa Romeo and Maserati products. Apart from that, the engine which is reported to be named as “Tornado” would also see its applications in Ram pickups and the Dodge Charger and Challenger. Among the upcoming models under the FCA’s sun, we can expect the new inline-6 engine to be debuted in the Jeep Wagoneer. According to the report, if not the Wagoneer, the next generation Jeep Grand Cherokee is on the table for the new engine.

We are not clear if the upcoming inline-6 would share the same platform as the inline-four in the company’s line-up, which can, in turn, lead to significant cost-cutting. If an inline-6 does come to fruition, we likely won’t see it until after 2020 when the Wagoneer is scheduled to debut.
