Pentastar upgrade

For 2016, FCA released an updated version of the 3.6 L engine. This engine now features upgrades to the variable valve timing (VVT) system, two-stage variable valve lift (VVL), a new intake manifold, new valve springs, new piston rings, new fuel injectors, new ignition coils, a cooled Exhaust gas recirculation, EGR, lower internal friction and lower weight. It also features a higher compression ratio, increased from 10.2:1 to 11.3:1. These improvements help to increase power as well as efficiency. The new version, however, has lost its flex-fuel capability.

Production

The Pentastar engines are made in three different factories: Dundee Engine Plant, Trenton Engine Plant and Saltillo South Engine Plant.

Insiders initially reported that the engine would come in four basic sizes (3.0L, 3.3L, 3.6L, and 4.0L), each offered in engine tuning, various states of tune. The 4.0L has been dropped from the list and a 3.2L added, while Fiat's investor website, as of December 2011, specifies the 3.0L with Fiat's MultiAir technology. The 3.6L engine itself has different horsepower ratings in different vehicles, and has higher horsepower (305 hp) and torque (268 lb-ft) as used in the Dodge Challenger

Single and Twin-turbocharged variants had been planned for 2015. These engines were projected to produce around , respectively. Direct injection was also planned.

Due to the new ownership structure, Fiat has obtained the right to use these engines, and currently adopt them in the larger models of Lancia and Fiat brands.
