The lighter, sportier, V8 Aston will undercut the V12 DB11 by £13k; due to make its debut at Goodwood Festival of Speed

Aston Martin has created a new, V8-engined entry-level DB11 by using the first Mercedes-AMG engine to come from its technical collaboration.

The new V8 DB11 is cheaper than the existing turbocharged 5.2-litre V12 DB11, but it is claimed to be the more dynamically able, thanks in part to its lighter weight and lower centre of gravity, due to the engine’s smaller capacity.

The twin-turbocharged 4.0-litre V8, familiar from the Mercedes-AMG GT, is built by AMG but has received unique calibration with its own ECU. The engine is installed by Aston Martin and produces 503bhp and 498lb ft of torque.

Although that peak power output is 97bhp short of the V12’s. The new model stays within a tenth of its pricier sibling over the 0-62mph sprint, taking 4.0sec to the V12 car’s 3.9sec. It tops out at 187mph, which is 13mph shy of the V12 car.

The V8’s lower placement in the engine bay comes as a result of new engine mounts and a bespoke, slimline wet sump. The V8 model is 115kg lighter than the V12 car, with a kerb weight of 1655kg.

The more compact engine is also located closer to the middle of the car’s wheelbase, which enables improved agility. Aston Martin chief technical officer Max Szwaj calls the V8 DB11 a car “with great depth of character and ability”.

This is enhanced by revisions to the suspension bushing, wheel geometry and anti-roll bar adjustments. The V8 DB11 also gets unique spring and damper settings, as well as a retuned electronic stability control system.

Aston Martin has applied minor aesthetic changes to the V8 model to signify its different powertrain. The 20in wheels get a unique finish, there are two bonnet vents rather than the V12 car’s four and the headlight surrounds are darkened. However, the cabin remains unchanged, with the same trim and options as the larger model and the availability of full ‘Q by Aston Martin’ customisation.

Along with being the more sporting DB11, the V8 model is expected to greatly increase the car’s reach, particularly in countries where emissions limits are strict, such as China. The V8 DB11 emits 230g/km of CO2 to the V12’s 265g. Claimed fuel economy on the combined cycle is 28.5mpg, compared with the V12’s 24.8mpg.

Aston Martin CEO Andy Palmer said: “With this new V8 engine option, we have broadened the DB11’s appeal by offering a car that’s more affordable while still blessed with the exceptional performance and memorable character that sets Aston Martin apart from its rivals”.

The V8 DB11 is on sale now, priced from £144,900 — £13,000 less than the V12. The new car will make its dynamic debut at this weekend’s Goodwood Festival of Speed. The first deliveries are due in the final quarter of this year.

Aston doing a lot right these days. V8 DB11 sounds excellent. Would love to see them using straight 6 engines again too, whether in DB11 or in the next Vantage.

No Never it has to be V8s & V12s.

Just before anybody says this is a Mercedes engine, let me just say it's not. It's an Aston engine, just that they were kind enough to let Mercedes use it too.

Don't forget what AMG stands for:

Aston Martin Group.

See, it's an Aston Martin engine!

This is quite sad to see an Aston Martin with an AMG engine. With AM designing and building their own sublime V12 engine in the DB11, surely they had the capacity to develop a smaller V8 version which would also have seen economies of scale too. The AMG V8 may make a nice sound but that's about it, it's not exactly a great engine. AM could have made a much better V8 themselves. Even the existing Jaguar V8 found in the Vantage is a far better engine that this AMG unit, despite its age, while it's proven in motorsport too.

It's a bit much to ask a company the size of Aston to create two completely different engines. The Merc engine will be reliable and powerful. It's a state of the art powerplant after all. It's not like they've stuck a pushrod GM V8 in it. And the technical backup they get with MB is first class too. Calm down for heaven's sake...

If the V12 is of a modular design then spinning off a V8 could easily be achieved with minimal cost and using the same production facilities.

You can't make a satisfactory V8 from every V12. Ask Jaguar, they tried to make both a V8 and a straight 6 from their legendary V12 and it just didn't work out well. And it took years of wasted work too... And with all of the complexity of a modern engine it would be even harder to do now.
Why go through all that when you can get a great engine and all the backup and subsystems you need from Mercedes?

Love the purple interior!!!

Crying shame. Worst fears realized. I have two Astons, and I have ZERO interest in an "Aston" with an off-the-shelf someone-else's engine -- it comprehensively ruins it for me. It doesn't matter at all how good that engine may be -- it's appalling in principal. An Aston Martin deserves an Aston Martin engine. Roadster, I am also a Jaguar fan, but you must know that the Vantage’s V8 is not a Jaguar engine. It’s “derived from” the Jaguar engine, but has bespoke, Aston-only, block, crank, rods, pistons, heads, cams, valves, etc. To me, that makes it an Aston engine. The AMG V8 is in no way an Aston engine and it has no business being placed in an Aston. To add insult to injury, it can’t even be seen under the bonnet/hood because it’s buried under a plastic cover. Maybe that’s because they’re embarrassed… How very sad.

I have both V8 & V12 DB11.

    It's got funky looks and a charming interior, but it's another small SUV, and another dynamic miss. Numb steering is just one thing keeping it from class best

    Diesel version of Skoda’s junior SUV is unobtrusive and undemanding, but we’d still go for the silkier petrol version of the Karoq

    Expensive and flawed but this understated diesel-electric Audi Q7 has a lot to offer

    Is the third gen Citroën C3 ‘fresh and different’ enough to take on its supermini rivals? We spend six months with one to find out

    A satisfying rework of the X3 that usefully improves its handling, cabin finish, space and connectivity to make this BMW a class front-runner again
