The V8 Vantage was initially powered by a 4.3 L (4300 cc) quad-cam 32-valve V8 which produced hp (kW) at 7,300 rpm and lb·ft (N·m) at 5,000 rpm. However models produced after 2008 had a 4.7 litre hp (kW) V8. 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 center of gravity. The cylinder block and heads, crankshaft, connecting rods, pistons, camshafts, inlet and exhaust manifolds, lubrication system, and engine management were all Aston Martin designs and the V8 engine was assembled by hand at the AM facility in Cologne, Germany, which also built the V12 engine for the DB9 and Vanquish.
