Aston Martin wants hyper-car to be faster than F1 cars

[Peter1919]

The rear and side views look great but that front view is IMHO very ugly

[humble sabot]

So, thinking about the rear suspension. .......

I'm guessing it's more like the Nissan P35 / NPT-93 with the lower A-arms pulled all the way up almost in line with the half shafts:

You're almost certainly right. And it was my first assumption as well. I'm just spitballing, wondering if they went extra creative on it. It's not ideal for maintaining the tyres' angle with the tarmac anyway, but would, if somebody wanted to, give an incredible amount of freedom in the underbody.

Not sure I understand the aura around Cosworth these days. They certainly are not the same company that did the good stuff back in the day. Their last foray in to F1 wasn't exactly Earth shattering.

Also, does "Cosworth" mean the one owned by the Champ Car guys or the one owned by Mahle (i.e. Mahle Powertrains)?

They did an excellent job on the unit in the One-77 by all accounts, and I'm fairly sure the Champ connection is not relevant, meaning this is the same outfit, give or take some personnel changes over the past couple years, as had their hands deep in F1 engines as recently as 2014. Earth shattering maybe not on the last count, they didn't find a customer, but they've still been playing in the same range and do have an institutional memory that ought (if records haven't been destroyed) to help with accomplishing their goals. And they did manage to be the ones who turned out the highest revving engine of the F1 NA era.
With regs changes there's no room for a DFV of the modern era. I wouldn't hold it against them, and unlike Ilmor, they do have a track record of engineering to road use. 154hp/L and enough low end torque to pootle around town shouldn't be too great a stretch for them.

there's a relevant bit down this page: http://www.f1technical.net/features/18858
something about a v12 and 20krpm

[bill shoe]

Joe Saward claims the new V-12 is an outgrowth of the Ford V-6 Duratec engine which is a highly regarded engine but not an obvious candidate for a hypercar engine. I think Aston has already turned this architecture into a V-12 for their regular cars. Perhaps the hypercar engine is simply that same current-production V-12 with a full-on Cosworth tuning job? But I'm skeptical that the architecture of a mass-production streetcar engine would meet the targets for size and weight in the Aston RedBull car. If it's true then it's a delicious example of mundane powertrain roots in a mega high-end car.

The 900hp Cosworth V12 which will be seen in the Adrian Newey-designed Aston Martin AM-RB 001 supercar, for example, can trace its roots back to Porsche, which created a 60-degree V6 engine back in the early 1990s, but then decided not to use it for production cars. The design was sold to Ford and the resulting engine was the Ford Duratec V6, an aluminum unit with dual overhead camshafts. The designers at Cosworth, which was then owned by Ford, then mated two of these engines end-to-end and created the 6-litre V12, which ended up belonging to Cosworth and being used by Aston Martin in its 1999 DB7 Vantage.

It's a good thought, but I'd gander a guess that geared hubs would add far to much weight to both the car and the rear unsprung masses.

[humble sabot]

At first blush it kind of looks like it but in fact if you think about it, it's actually less material, and less is actually unsprung. The hub itself may be a tiny bit heavier but the mass of the moving parts locating it in space is much reduced. It does have the disadvantage of moving the mass outwards though.

The rear and front will both change to make sure the car is legal, so expect the production car to be slightly different

Did somebody mention a likin' for "the smell of napalm in the morning"?

Time will tell if she earns the A-M style V-moniker/nickname of 'Vainglourious', instead, I guess..

So, thinking about the rear suspension. I was wondering, would it make sense to fit a long control arm setup? Or is it conceivable that they might be going a similar way to Ron Mathis, who's also a race car designer working on a road car platform:

I do wonder if it would still be so light if it was engineered to deal with 4g of cornering, but it apparently works pretty well on the 900-1000lb Edison 2


Pretty sure the GTR LM Nismo setup isn't germane since it's unpowered and the geometry doesn't fit.

OR, like these, raising the arm mounting

It essentially is. The upper pivot mounting on the P35 is ~515 mm from the RP, where the Merc and Torro Rosso is ~450 mm (yes, I make CAD drawings of all this stuff ).




The difference is it's a lot easier to package the suspension inside a 17" - 18" wheel rim than a 13" one, so those two F1 teams have chosen to employ the goosenecks to reach up and out of the wheel rim to pick up the upper pivot.

So do you think the Aston Martin Redbull will beat this Chinese car

That was an interesting video. Reposted below for those that get the error.

Just opened this topic, since I just saw a video of the Nio too. Not sure if this has been posted yet, but here is an interesting video with an engineer of the car explaining some of the aerodynamics of the car:

https://www.youtube.com/watch?v=nPaUr4elS5E

What strikes me as quite amazing is the stuff that is going on underneath the car, e.g. the air channels. Never thought about what possibilities you had by going fully electric and having room for channels and such where in a car with an IC would be loaded with exhausts, drive shafts and other stuff.

Amazing car, and great video to watch, thanks Phil

But that does not deserve its own thread?


Amazing car, fastest than a Porsche 918, wow
