For sure, but I think some of that is the limitedness of it. Even Ferrari’s look like mass produced cars by comparison.

12100 rpm, folks! Sounds pure 90's F1 to me.

Dario looks genuinely emotional there at the end. I'm surprised he didn't try to get in the test cell with the engine. 8) :lol:

They say in this video the pistons are made from a MMC. I did some quick digging and it seems to be from Materion’s SupremEX which is an aluminium matrix with silicon carbide re-enforcement. I don't know what grade they are using, but here is a data sheet for their highest strength grade

As someone whose materials science is sadly lacking, how does that compare to the "usual suspects" used in such items in engines?

I am far away from an expert in materials science and engine design, from what I found (quickly) one aluminium alloy used in pistons is 4032, which is primarily an aluminium-silicon alloy. Here is the matweb page for 4032. It seems to have about 1.4x the yeild strength, 1.7x the young's modulus, lower coefficient of thermal expansion and similar thermal conductivity. Too bad the 640XA data sheet doesn't provide any specs for 300c vs just room temperature.

Let's discuss the tyres.
  • McLaren F1: 235/45/17 fronts, 315/45/17 rears.
  • GMA T50: 235/35/19 fronts, 295/30/20 rears.
Why such smaller aspect ratios ? Possibilities I can think of include:
  1. Fashion.
  2. The brief has changed from sports-touring more towards sports. The car will be less comfortable with more NVH in return for (perceived?) better handling response and/or steering feel.
  3. Modern tyres can provide similar comfort with lower profiles.
  4. Modern dampers can provide similar comfort with lower profile tyres.
  5. Larger wheels were needed for mechanical and brake packaging.
  6. The original 45-section tyres were an eccentric choice by Murray which suited his personal tastes but almost nobody else's.
Anyone have any thoughts on this?

Tires have come on leaps and bounds since the 90's.

I assume that's not a V12 in the back there?

Assumptions based on what?? It is a V12 yes

Well it sounds nothing like the one that we have a test bed video of. Much more like some form of forced induction V6 maybe?

It's still a test mule at the end of the day, so they may have a different engine in one of them if it's for testing other things.

It's the V12, but its capped at 5000 rpm at the moment.
