Confirmation de la motorisation V12 5.2 twin-turbo pour la DB11
"Naturally aspirated Astons, RIP. The new 2016 Aston Martin DB11 will be powered by a new twin-turbo 5.2-litre V12, the company announced today - spelling the end of a free-breathing, old-school era at Gaydon.
The news confirms CAR's earlier scoop that Aston's V12 would switch to forced induction, after our spies caught a prototype with intercooler switches onboard. The move comes as all car makers, from Porsche to Ferrari, scramble to downsize in a bid to cut emissions.
The new engine which will be unveiled officially at the 2016 Geneva motor show. It's described as a 'brand new V12' and the capacity is a chunky 700cc or thereabouts smaller than the outgoing, Ford-built powerplant.

Our sources suggest the 5.2 will become the company's most powerful V12 in history, despite the reduction in capacity; the twin turbochargers mean that its power output will be in excess of 600bhp. It will again be built in Cologne, at Aston's engine plant in Ford's factory.
We expect that the DB11 range will swell from a single engine to a choice of V12 or V8 power, as Aston Martin introduces a Mercedes-AMG-derived smaller 4.0-litre V8 in the coming months. It should increase the 'footprint' of the market it competes in, echoing the approach that's worked so well for big-selling Porsche."
