Pentastar motor

from allpar

Here are some of the major innovations, as far as we can tell:

Variable cam timing with dual independent cam phasing to flatten the power output
Exhaust manifold integrated into the head itself
Chain drive
Canister-free oil filter element on top of the engine — prevents landfill, allows incineration, eases oil changes
Oil to antifreeze oil cooler in the "V"
Lightweight block — saves on aluminum and reduces overall vehicle weight (improving balance, too); reportedly 20 lb lighter than GM’s V6 block, saving $40/engine on aluminum
