Aston Martin Valkyrie V12 secrets exposed | carsales

[JOHN] Cars like the Aston Martin Valkyrie
only come along once in a generation. The fruits of a partnership between a famous
British sports car maker and its F1 partner, Red Bull. The radical Aston hypercar is the brainchild
of none other than legendary Formula 1 aerodynamicist, Adrian Newey. Now, Newey isn’t one to compromise, so when
he wanted a naturally aspirated V12 to power the Aston hypercar, he wasn’t prepared to
settle for an off the shelf item. Instead he called his old friends at former
Formula 1 engine builder, Cosworth. Because only Cosworth could deliver what he
wanted, a V12 that weighed just 200 kilograms, revved to the high heavens, produced a cool
1000 horsepower, and lasted for more than 100 000 kilometres. And that’s why we journeyed to the British
engine builder’s HQ, to get up close and personal with the man who delivered what most
thought was impossible. So this is Bruce Woods, he is the managing
director of Cosworth, and this guy has been involved in everything from Formula 1 to Fast
Fords, but I believe this has been a particular challenge for you. [BRUCE] Yes, absolutely. It’s an incredible thing to have the opportunity
to work on, and this is definitely going to be one for everybody involved to tell their
grandkids about, so this is something very special for Cosworth. [JOHN] I think first, actually, Bruce has
to tell us about where we’re standing now because I’ve been to some industry test beds
in my time, but this room is absolutely insane. [BRUCE] This is one of ten dyno cells that
we have at Cosworth. Three in a row here, and amazing capability,
so these were designed for Formula 1. You wouldn’t find cells like this in any
other facility other than Formula 1. [JOHN] Tell me if this is true or not, but
normal dynos are pretty boring places, aren’t they, you just spin up a wheel, it produces
horsepower. This thing can replicate the forces of a full
record setting lap at the Nurburgring. How cool is that? [BRUCE] It is an amazing bit if kit, so 1000
kilowatts, 100% overload, so you can run 2 megawatts, 24000 RPM, and when we’re running
through a Nurburgring cycle, then with the transient capability, we can replicate all
of the gear shifts, so it’s a real spectacle to see the engine. The maximum power is made at 10500 RPM, and
we’re not rev limited till 11.1, so each gear shift is happening between 10.5 and 11.1. It is an incredible thing, both to see and
to hear as the engine goes round the lap of Nurburgring. [JOHN]] They talk about a power race and super
cars, but this is next level. [BRUCE] Yes, so one of the key targets at
the beginning was absolute power. Kilowatt numbers, the engine itself is delivering
about 746 kilowatts, and then on top of that there’s the hybrid electrification motor. 746 isn’t such a nice round number, but
in horsepower, that’s 1000 horsepower, which is obviously a great number to conjure with. [JOHN] I guess the horsepower was only the
beginning of the challenge that you face because you work with a certain man called Adrian
Newey, who is a pretty tough cookie in the world of Formula 1. He’s the guy responsible for a much of Red
Bull’s success. He’s an incredible designer, but he’s quite
the taskmaster. Tell us some of the specifics he wanted from
this engine. [BRUCE] We started out with power, so we actually
started out with 950 horsepower, it became 1000. We have to meet Euro 6 emissions. We again were very keen to rev beyond 10 000
RPM. [JOHN] In a road car, 10 000 RPM? It just beggars belief. [BRUCE] It is crossing a threshold that hasn’t
been done before. There’s engines that rev to 9, there’s nothing
in a road car that goes to 10, so we wanted to cross that threshold. And then critically all of this had to be
packaged in something of 200 kilograms weight target and to be the structural element of
the entire car. [JOHN] And that’s crucial, isn’t it, because
that helps Adrian Newey achieve some of his engineering goals? [BRUCE] To achieve the vehicle weight target
it was critical that every piece of material in the car is doing more than one job. In the case of the engine not only is it producing
the power, it’s holding the back and the front wheels together. [JOHN] What was it like to work with Newey? Does he change the goalposts? Does he put pressure? Does one week say I want the engine to be
200 and then maybe next week he says 193? [BRUCE] No, working with Adrian was fantastic. He is certainly very single minded and very
demanding, but what he wants to drive you to is the best you can do. When we were set the target of 200 kilograms
we did not know quite how we were going to deliver that. We tried to talk Adrian into more like 220,
he wasn’t having any of that. In fact, we’ve delivered about 205, 206, and
he’s happy with that because he can see that we have put every piece of engineering,
simulation analysis and technology into making the weight as low as we can get it, and 205,
206, is about it.
