Turbocharged V12 for Aston Martin’s DB11

ASTON Martin has released a teaser video for its forthcoming DB11 supercar and revealing that it will be powered by a 5.2-litre twin-turbocharged V12 — the first time the marque has embraced forced induction.

The origins of the engine remain a mystery for now, but it is likely to be downsized version of the hand-built 6.0-litre Mercedes-AMG unit that powers the SL65 sportscar and S65 coupe, cabriolet and sedan range.

In 2013, Aston signed a powertrain agreement with Mercedes-AMG to replace the company’s ageing engines.

At the time, only a replacement V8 was mentioned, prompting speculation that V12 power would disappear from the range.

However, the video suggests the Mercedes collaboration has either cleaned up the old unit or – more likely – replaced it with Mercedes metal, GoAuto reports.

No power, torque or performance figures accompany the 30-second snippet, but using Mercedes’ 463kW/1000Nm 6.0-litre as a guide, the new 5.2-litre DB11 could have about 400kW and 860Nm, although its smaller, higher-revving capacity is likely to push the power higher while sacrificing torque.

Aston’s current power champion – the V12 Vantage S – pumps out a hearty 441kW from its naturally aspirated 6.0-litre V12, while the DB9 that the DB11 will replace has 409kW from its 5.9-litre V12.

It is unlikely the company will let the DB11 to take a step back in power.

Aston’s previous range of Ford-sourced, naturally aspirated V engines were feeling the weight of emissions regulations around the world, as well as the United States corporate average fuel economy (CAFE) ruling.

But like many other manufacturers, Aston has looked to turbocharging to bring emissions back into line without sacrificing performance.
