RE: McMurtry Spéirling takes FOS Hillclimb record

As a casual observer I tend to agree the Speirling showed significant DF throughout the ascent. OK, the Goodwood bends are fairly shallow but its speed carried through the bends looked astonishing, as evidenced by the crowd reaction. The tyres don't look hugely wide (no doubt very sticky rubber, but presumably no pre-heating allowed) yet the website claims >3G cornering potential https://mcmurtry.com/speirling/ I guess the simple answer is to just ask the team how the DF varies with speed?
Dumb techie question: how does one measure real-world DF? Strain gauges/sensors in the suspension? Or cameras recording the spring compression?

One of the most exciting automotive innovations in recent years.
Think of the low-volume specials that can be created with an old Tesla motor and some batteries.
I think the hypercar playbook of the next generation will unlock the potential of integrating all these nascent technologies - AWD with motors providing real torque vectoring, fully active suspension and steer-by-wire all working in symphony.

I don't think it had much fan DF, because otherwise he could have been later and harder on the brakes and unlike a conventional aero car where you must relieve brake pressure as the speed scrubs off, he should have been able to brake at a consitently high G right down to zero speed if necessary.
0.9 of a second faster than the IDR, most of which i suspect was in the first 100m says this car hasn't got any more DF than that one (especially as it meant to also have a significantly higher (33%) Power to Mass ratio).
My suspicion is that the porousity of the road surface is a major problem at speed........

Really can't see how it will have any impact. Lack of lateral grip is not a factor on any hypercar on the road today. It's all totally unusable.Think of the low-volume specials that can be created with an old Tesla motor and some batteries.

They were the sounds of inefficiency, of wasting 75% fuel in heat and noise, of forever desperately trying to compensate for the ridiculously peaky torque curves of ICE's with boxes full of mechanical gears and clutches, of primitive mechanisms that were in essence still based on reciprocating steam engines, but noisier.

Measuring the inlet pressure to the extract fan is also going to give you a very good idea of the DF created by that fan!

There isnt much braking required on that run, the only heavy braking point is a bI don't think it had much fan DF, because otherwise he could have been later and harder on the brakes and unlike a conventional aero car where you must relieve brake pressure as the speed scrubs off, he should have been able to brake at a consitently high G right down to zero speed if necessary.

h of a road surface so you tend to give more progression there anyway.A proper circuit should be bonkers in the slow speed compared to a conventional car.

Don't try and make them like them (I wish designers generally would also appreciate this).
Nobody tried to make cars sounds like horses

There are way better ways of locking/securing your house but people love a physical key.
People like the security of familiarity. If it looks like a car, drives the same, has same controls and same general layout, only instead of filling it with gasoline you fill it with electric then that's OK.
See it as evolution - take too many steps at once and it all collapses, loads of great inventions and designs that have failed for being "ahead of thier time".

Lots of things we do are for enjoyment are antiquated, but we still do them because we enjoy them. ICE cars are no different.tr3a said:

There's no aversion to tech per se. I drive a Yaris and Mercedes, both laden with tech and I'd rather like the latest NSX in my garage (as well as an old one). Just celebrate the fact that we all have different tastes and that 'better' will always be subjective when it comes to quality comparisons. Even more so when comparing apples and oranges in a competition where only apples are allowed to enter. You say that it "may feel good" but to go on and try to undermine that feeling indicates you don't empathise with a very large number of people,

But, we make the mistake of thinking what we prefer really matters, it’s more about what the majority likes, wants and prefers.
We will die out, the kids watching the McMurtry on Sunday will take over and the things they saw in their formative years, like I saw Sierra Cosworths, Metro 6R4s and the like will come to the fore.
Not sure how their will be an EV scandal as someone mentioned, the diesel ones was about cheating emissions, they don’t have any tail pipe emissions to cheat so not sure how that would work ?
I do love the theory that EVs are a government scam to extract cash from people, yes, I am sure that clueless lot could organise that, and rope in other countries and global corporations, obvious really…
