Yeeeesssss!

Great engine, and glad AM are willing to stick two fingers up to the "Green Brigade", well done AM, a few other manufacturers should take note

What a masterpiece! Probably one of the last of it's kind. What a swansong though.

I wonder if Merc are just a very tiny bit concerned that they opted to go with F1 technology (and crap sound) for their engine? Round 1 to AM.

I very much doubt they're concerned, aren't they all sold?

Yeah you are probably right, maybe Merc won't care but the owners will probably feel a little bit sick when they are trundling around in their hypercar which doesn't sound much better than their Dyson back home knowing they could have had the Aston.

Engine sounds like an L60, that's a massive compliment!

[ZX10R NIN]

Wow that sounds amazing.

[anonymous-user]

Wow. It's marvelous.

I'm not sure it's that straightforward. I think they can get around certain emission regs because this will only be made in such small quantities....?

I think this will go down as one of the all time great engines.

I doubt it.

Nicely written article.

Yeah - but they are very different cars.
Not sure many Merc Project One owners could physically climb into a Valkyrie.
Different strokes etc.
Both will be sensational.

Can anyone explain why moving the "cog driven camshafts ... to the rear of the engine rather than the front" will make a difference to the noise that they create?

It's not so much the noise they make directly (though there is some audible noise), it's more the vibration, that in close proximity to the rear of the cockpit tub, would transmit through it - while it's good to feel a connection to the engine, it's another thing to have the geardrive feel like it's chewing through the back of the cabin.

ETA; it's likely a quirk of the packaging requirements imposed by a certain Mr. Newey. Genius he certainly is, but he likes to keep everything packaged so tightly for aero reasons - something that other manufacturers probably just allow more room behind the firewall for a regular camdrive setup to dissipate.

In the Carfection video, I think the Head engineer says they took a 4 cylinder block? but just used 3 cylinders. Given its Cosworth I suspect they might have used that 4 cylinder engine they developed a while back for that Jag CX-75, the one that had like 500hp and a 10,000rpm red line?

I'm not sure it would have been as that was a 1.6 so the capacity doesn't add up unless they substantially re-engineered it for a test engine, a 3 cylinder version would have been 1.2 litres and would have made a V12 of 4.8 litres.

Cosworth must have a 2.2 ish litre 4 cylinder with 330bhp or so (if it revs to 11k obviously) that nobody knows about...

Is no one going to mention that the engine has to be replaced after 62,137 miles?

If this was an EV people on here would be going crazy if the battery only lasted 62k.

Given expected annual mileage (of zero!) for most of the cars being bought that is still a long time. No doubt petrol engined cars will have been outlawed altogether before many get close to that figure

In the video they were talking about doing durability testing of 100'000km of Silverstone, Nurburgring and "high duty" road driving. Maybe compare it to a 911 GT3 RS that had done that many miles mainly around tracks and you'd be fine with that requiring a "refresh" at that distance.

I thought that was a truly remarkable durability figure for a 1000bhp engine doing 11k RPM while functioning as a stressed member in the chassis. I daresay that VAG gewgaw Veyron/Chiron has higher requirements.

I always thought McLaren should have called their hot models Can-Am.

600 Can-Am sounds way cooler than long tail that isnt.

Anyways: there should be a violent Can Am racing series with only this motor, provided by Aston/Cosworth and with yum bodies to match. Max 800 kgs and go go go!

It's my guess both Formula 1 and E will be forgotten when a Can Am series will be the F1 support act!

It wouldn't surprise me if a number of the owners had both.
