The Chrysler Pentastar engine family is a series of aluminium (die-cast cylinder block) dual overhead cam 24-valve gasoline V6 engines introduced for the 2011 model year in Chrysler, Dodge, and Jeep vehicles.

[2][3] The engine design allows the use of E85 or 87 octane fuel and features dual variable valve timing.

[4] Insiders initially reported that the engine would come in four basic sizes (3.0, 3.3, 3.6, and 4.0 L), each offered in various states of tune.

[5] The 3.6 L engine itself has different power ratings in different vehicles, and has higher output 305 hp (227 kW; 309 PS) and 269 pound force-feet (365 N⋅m) of torque when applied in the Dodge Challenger.

These improvements increase power as well as efficiency,[12] however the new version no longer supports flex-fuel capability.
