Pentastar V6 receives a major efficiency improvement for 2016. The 3.6 litre Pentastar V6 has a 6% better fuel economy, a torque below 3000 rpm jumps nearly 15%. It is possible by a combination of 2-step variable valve lift (VVL), upgraded variable valve timing, improved intake ports and a new intake manifold.
The interesting feature of the engine is its Variable Valve Lift(VVL). The system varies the valve lift from .230-inch at low speed to .410-inch when higher power demands are required. The lower lift reduces pumping losses, then at around 2,800 rpm the system switches to the high-lift lobe. It’s all activated by oil pressure and solenoid valves.
