The new engine builds on the strengths of the
old one and adds
iron - coated
cylinder walls, graphite - coated pistons, reinforced pistons made out of a new steel alloy, a freer - flowing intake, and a pair of new 350 - bar (5,000 psi) direct injection fuel pumps (one on each
cylinder bank) to yield an increase of 67 hp and 74 lb - ft of torque over the previous iteration of the 4.4 - liter eight -
cylinder.
The engine dumps the
old 1.4 - liter's
iron block for an aluminum construction, which with the aluminum
cylinder head, makes all - aluminum engine with an obvious reduction in weight.
