The engine block is high-pressure die-cast aluminum for strength and light weight. Twin independent variable cam timing allows the camshafts to operate both intake and exhaust valves at different times in the combustion cycle, based on speed and load. And to further lessen weight, the intake manifold is manufactured from a composite.
