3.6L V6 engine

Lighter but more powerful than its predecessor, this new 3.6L V6 engine employs sophisticated direct-injection technology and Variable Valve Timing to produce pulse-pounding oomph (323 hp, 278-lb-ft of torque) without sacrificing fuel economy. Optimized injectors deliver precise amounts of fuel directly to combustion chambers in the redesigned cylinder head, maximizing efficiency even at full throttle. That contributes to a pleasantly surprising 30 MPG (highway), according to EPA estimates for the 2LS. A new fuel pump and isolated fuel rail help it run more quietly, too. Overall, this V6 delivers an exhilarating but exquisitely balanced driving experience.
