New forged steel crankshaft provides the 91mm stroke and incorporates new holes in the counter weight is reduced rotating mass and improve inter-bay breathing. New forged steel con-rods and cast aluminum pistons complete the capacity-related changes.Performance improvement has been achieved through a number of changes carefully developed to be recognized engine.The cylinder Aston Martin V8 Bore and stroke has been increased from 89mm to 91mm and 86mm to 91mm respectively, giving a total displacement 4735cc.Increased cylinder bore is facilitated by a move to cylinder liners are pressed into blocks of pre-machined aluminum alloy, enabling thinner liner than is
possible with a cast-in design of the 4.3-liter engine.Other important changes include efficiency improvements in the dry flood lubrication system, including new flood casting with oil pick-up points moved from the front and rear on the side of the flood. Cylinder heads are modified with a new intake port and inlet valve size increase from 34.9mm to 35.9mm. This intake manifold has been modified to fit the new ports to optimize airflow.In the cabin, the newly built center console of die cast zinc alloy with a graphite silver finish is introduced along with a new ECU – first seen on the Aston Martin DBS in 2007. ECU – constructed from glass, polished stainless steel and polycarbonate – replaces the key used previously for the Aston Martin V8 Vantage. Revised car also includes a new route processing Hard Disk Drive
