3.6 L LFX V6

The LFX is an enhanced version of the LLT engine developed jointly by Holden and Cadillac. Introduced in the MY2012 Holden Commodore SV6/Z and the MY2012 Chevrolet Camaro LS/LT, it is 20.5 pounds (9.3 kg) lighter than the LLT, due to a redesigned cylinder head and integrated exhaust manifold, and composite intake manifold. Other components like the fuel injectors, intake valves, and fuel pump have also been updated. They also included the addition of Cam Phasing Variable Valve Timing. Power and torque are up slightly from the LLT. The compression ratio is 11.5:1. The LFX also features E85 flex-fuel capability.
