DB9 engine



The people of Aston Martin will not be so presumptuous to call their twelve-cylinder as the best in the world. They state this only of its sound qualities. This are subjective sentiments and more difficult to verify. This is concerning a Ford group engine, at which Cosworth already should have helped to develop. The initial development is probably of Porsche. Comparing bore and stroke, then the relationship is significant. However, imagine it is not so easy to transform a V6 into a V12.

Vanquish engine


It is not enough to extend the individual components such as cylinder block, -head and crankshaft, because for example the firing order must be distributed completely new. Also changes the torque conditions of the crankshaft, because the way from the first cylinder up to the power supply to the clutch is more than doubled. And look the again increased level of speed. While the moments are comparable, the capacity increases once more 2.4 fold.

DB7 Vantage engine



BMW has made in the 70's also of a six- a twelve-cylinder. However, it was thought of an inline engine, which considerably simplified the matter. Here can possibly even the cylinder heads and until the chain drive the complete engine control be assumed. So good the developer of the new Aston Martin V12 do not have.
All in all there are not so many engines in the history of Aston Martin. Before the Second World War, there is the 1.5 - and 2.0 four-cylinder. The latter changed 1936 for more practicality in everyday life. The first civilian versions after the war have already the from Walter Owen Bentley for Lagonda constructed six-cylinder. In the DB 4 comes then a new design of Tadek Marek also with six cylinders.
