RE: McMurtry Spéirling takes FOS Hillclimb record
Discussion
I saw this going up the hill and it was mightily impressive. Looks absolutely tiny, especially when compared to some of the modern race cars.
In no way diminishing what McMurty have achieved, but as I watched this along with the Ford Supervan EV and the Cayman Gt4 EV absolutely fly up the hill making some very quick ICE cars look a little pedestrian, it did strike me that EV's are particularly well suited to hill climbs as a demonstration of their ability.
All the things they're good at, ballistic standing starts, instant throttle response, colossal torque everywhere and no gears to worry about give them an obvious advantage on a single attempt at a short course without any concern over range or (relative) lack of top speed that a multi lap format on a full size race track would expose.

That Group C Jag though - remarkable speed, I winder if we will ever see a Sauber C9/11 Merc trying it’s chances up the hill.
{Imagine group C class only racing up the hill … what an experience that would be}.
Whilst undeniably impressive (and my favourite class of racing), a group C car isn’t an ideal hill climber. Look at the exit speed of the cars, the big jag was only just getting going. At the finish line it was starting to gather serious pace crossing the line at 146.2 mph. That’s a fair bit faster than the other IC cars. Even the mini bat mobile is limited to 150mph.{Imagine group C class only racing up the hill … what an experience that would be}.
The fan car is seriously impressive and I do wonder if it it could go much faster if the human was removed, thus reducing drag and weight, while also allowing the RC operator to take more risks. Get one of the top RC drivers in a helicopter and let’s see what they could do with it, freed from g force limits of the human body and our inbuilt self preservation instinct, I bet they could shave a few seconds off that time still.
Look at what justin Law does in the group C cars, where he's not leaving any margin.
Actually I think Justin Law could would have gone quicker in the McMurtry as hes got more experience of doing that actual run.

It will absolutely loose downforce as road speed climbs because the required mass flow of the suction fan will increase at least linearly with speed, thanks to the swept area of a porous tarmac (and probably far more steeply due to sealing issues). It's why its got massive traction off the line because at zero speed the fan has time to suck most of the air out the gap under the car, but as it starts moving more and more air arrives into that gap in any given unit of time, so suction must reduce.
The team are claiming slightly higher downforce at speed. (overbody aero?)otolith said:
Yep - they are going to sell them, but it looks as if they are after a wider business model than that.

Saw it do several runs over weekend and it was otherworldly.
I felt we were all watching a moment in history. A step change in automotive technology, particularly since their ethos is small and light while everyone else is going bigger and bigger.
Perhaps McMurtry is the new Chapman

this is the first EV car that i'd actually buy (or a watered down version) it's small, has british engineering and looks so much fun!
All of the runs were incredible (got some great shots of it hammering around Molecombe) and I was chatting to the guys in the paddock.
It's limited to 150mph and it was at that for 4 full seconds on the main straight
The version that took the hill had the full race battery pack as opposed to the ID R which was using a cut down one with less than 5 miles of range. If they used a custom battery they'd save 150kg and would shave 4 seconds off the hill time. 34-36 seconds was the time quoted to me.
It weirdly looks a bit slower on the video than it does when it's going past you and bending the laws of physics

Amazing achievement by a small team to take the hill record and an astonishingly different and interesting car!
But, it's clear its operating nowhere near its claimed performance:
no one is really bothered by that though, look at how people cheered it when it went past, it's the car of the weekend that everyone is talking about and rightly so imoBut, it's clear its operating nowhere near its claimed performance:
if anything to me it shows there is some glimmer of hope for a fun EV car in the future that i'd actually buy
That Subaru driver has the look of absolute life-threatening commitment! https://youtu.be/mpxP2FEM3HY?t=2149

That was good fun to watch, a tiny little thing that we could tell was really quick just by looking at it.
Shame they didn’t let George Russell and the 2019 Mercedes into the shootout though. It might have been close between them.
(I know the reasons they banned contemporary F1 cars from timed runs, but they’re now allowing cars that are just as fast).
I don't think Goodwood banned them, I believe the timed runs for modern F1 stopped due to the next regs on testing that came into force and that a timed run constitutes a test.Shame they didn’t let George Russell and the 2019 Mercedes into the shootout though. It might have been close between them.

I think even the year after 2000, Mcnish is the Toyota F1 posted comparable unofficial timed run tho Heidfeld's. (My memory could be off though...)

Will that limit the use of fans, then? That rather torpedoes this car's ambitions as a road vehicle, such would be a shame.
If they can’t control the noise (that car is pretty loud). I wonder how practical this system is on the road. esotericar said:
Why on earth would you want a fan car for the road? I mean, when you're in your neutral-aero fully laterally loaded road car cornering at 120mph through a quick A road sweeper, are you thinking, if only I had two tonnes of downforce so that I could be taking this at 150mph? Or when you're doing 50mph through a tight, blind B-road bend with no margin for braking should something unexpected appear, is it that what you really want is to be doing 80mph?
That's precisely my point.This is marvellous to see at Goodwood but I struggle to see how it could apply to road use. I'm not sure I like the idea of road users without Max Chilton's talent suddenly losing downforce on the Cat and Fiddle either...
Unless you have a "fan off" more for road use and "fan on" fit the track? I'd struggle to see how that'd work in practice though.
I don't want to moan about an amazing achievement but this strikes me as challenging to make work for road use.

Also while I'd very much enjoy a go in one on track, I suspect for all the other track users it would be like getting overtaken by a 150mph gritting lorry every 5 minutes!This is marvellous to see at Goodwood but I struggle to see how it could apply to road use.

I imagine they can sell a couple to rich people as a new "toy" but really this has no commercial validity. DF for the road is un-usable and dangerous, and a single seat car is simply not what consumers want because it just doesn't fit with peoples lifestyles
Not sure that they are planning to punt them out on PCP to couples + 2.4 kids though? Stuff like this - the new Gordon Murray creation, the Valkyrie, the Evija, even stuff that sells in the thousands like the aggregate sales of McLaren or Ferrari - it's all irrelevant. What's relevant to consumers and the industry is utterly boring family crossovers.It is an amazing achievement for a small team and a fantastic "look at us" car, but it's largely pointless in the grand scheme of things (see Capara T1 for ref...)
