Aston Martin DB11 V8

First AMG-engined Aston proves to be a V12-beating formula

by MATT SAUNDERS

ENGINE 3982cc V8, DOHC, 32v, twin-turbo / POWER 375kW @ 6000rpm / TORQUE 675Nm @ 2000-5000rpm / WEIGHT 1760kg / 0-100KM/H 4.0sec (claimed) / PRICE $368,000 HEREíS NO doubt that Aston Martin knew exactly what it was doing when it took the decision, four years ago, that would lead to the DB11 getting a twin-turbocharged V8 engine from Mercedes-AMG. Itís become an alternative to the Cologne-built twinturbo V12 and is an integral part of Astonís future, in all sorts of models.

Okay, the V12 has the faster 0-100km/h and higher top speed claims, so Gaydonís performance hierarchy isnít exactly in tatters. But with only 25Nm between the siblings and 115kg saved by the cheaper newbie, there was never likely to be much breathing space left for the pricier model. So why take the risk?

Interestingly there are reasons other than financial to consider whether your new Aston really needs 12 cylinders Ė and they're convincing.

On the back of that weight saving (and favourable redistribution of mass rearwards and within the carís T wheelbase), Gaydon has taken the opportunity to refocus the suspension and steering to make it handle better and involve its driver more.

Changes to the V8ís suspension include stiffer bushings and anti-roll bars front and rear, some altered wheel geometry and new adaptive dampers programmed for a greater spread of ride comfort and body control between the GT, S and S-Plus drive modes. Thereís a new lateral link in the multi-link rear suspension and a much greater sense of support from the rear axle. The spring rates in effect havenít changed, but the power steering calibration has, with an emphasis put on more weight and feedback and improved on-centre stability. But is it a better Aston Martin GT car? I guess thatíd depend how badly you want an Aston V12 engine.

But Aston has done a remarkably good job of making Affalterbachís 4.0-litre V8 its own. It sounds subtly different from that which youíll find in a Mercedes-AMG GT or an E63 S, thanks to new induction and exhaust systems. Itís more than potent enough to make the DB11 a first-class performer, and in some ways it even shows the V12 up a bit.

Having widened the gap between suspension modes, Aston has also created bigger and more clearly defined steps between the matching GT, S and S-Plus powertrain modes.

S suits the car best on the road, while S-Plus is for short bursts given it can make the car highly strung.

The vigour with which the car hustles from 3000 to 5000rpm is impressive. However, the DB11 V8ís handling is an even better advert than its engine. Improvements have been made to the carís feedback levels, body control and both its directional precision and its handling response.

It remains supple and compliant, but also keeps body movements in check.

The difference that weighty, newly communicative electric power steering system makes to your ability to gauge the level of grip under the front tyres is a big one too. It means you can explore the balance and adjustability of the chassis in a way you simply wouldnít risk in the V12.

At the end of a long drive, youíre left in no doubt that this car feels much truer to Aston Martinís long-standing tradition of building sporting grand touring coupes and proper driverís cars than its more expensive and powerful cousin. The DB11 V12 retains its place, of course, and as a more isolating, gentle-riding, luxurious distance machine, itís great at what it does. But for proof of the V8ís stature as simply a better-executed DB11, look no further than Aston Martinís plan to transfer most of the V8ís suspension and steering changes onto the V12 as part of next yearís model year revision. If I was going to buy a 12-cylinder DB11 Iíd wait until 2018 to do it. But on this evidence, I might not actually buy a V12 at all. M

Improvements to steering; V8 is the DB11 to have
