The V8 Vantage was initially powered by a 4.3-litre (4,280 cc) quad-cam 32-valve V8 which produced at 7,300 rpm and at 5,000 rpm. However, models produced after 2008 had a 4.7-litre V8 with and of torque. Though based loosely on Jaguar's AJ-V8 engine architecture, this engine was unique to Aston Martin and featured race-style dry-sump lubrication, which enabled it to be mounted low in the chassis for an improved centre of gravity. The cylinder block and heads, crankshaft, connecting rods, pistons, camshafts, inlet and exhaust manifolds, lubrication system and engine management were all designed in house by Aston Martin and the engine was assembled by hand at the AM facility in Cologne, Germany, which also built the V12 engine for the DB9 and Vanquish.
