Those two coat hanger hooks in the exhaust tip at 19.50 in that nobody noticed.
Looks like a device for igniting the exhaust gases to me.
Unless your P1 comes with those it won't make flames like it does in the video.
Great for making the P1 the hypercar of choice in the school yard but, really, does such an incredible car need such embellishment?

5. What are these small pipes running into the exhaust.
I'm guess they inject fuel in a kind of anti lag way? Or are they just there to make blue flames (which I will guess are not road legal and race mode only)
They ^^^ (the probes) are nothing more than a pair of 3mm K type thermocouples, used to measure the EGT at the tailpipe exit. Since it was found that the car could melt it's number plates, some extra attention was focused on this area ;-)I'm guess they inject fuel in a kind of anti lag way? Or are they just there to make blue flames (which I will guess are not road legal and race mode only)
ETA: you'll also notice the smaller exposed junction Thermocouples taped (with kapon tape) to the rear bumper just below the exhaust exit, with the aim of measuring the temp of the plastic in those locations

ok, School yard info ?Looks like a device for igniting the exhaust gases to me.

bulllshiiiit, development car with exhaust gas temperature sensors, probably because of the flames. I love that someone would come and say that on Pistonheads as if it's fact. Mclaren, one of the finest engineering companies in the world puts halfords exhaust flamers in for show? Yeah, course.

it also looked like the strut on the rear spoiler had a load cell attached to it Jesus H Frickin' Christ.

OK I'll go with temperature sensors it being a development car but I've never seen any car emit bunsen burner blue flames on the throttle like that before. Yellow on the over run sure but not like the P1. Any explanation for that?
Means it's more oxygenated combustion, I've seen others do it, Aventador has IIRC.The Pits said:

Have you not seen the 918? Now thats real mad flames(jet style)

sorry, must have nodded off somewhere around page 13!so basically they all do it now. I figured the Aventador was purely for show but I don't imagine Porsche would encourage such theatrics with the 918 and all its eco pretensions.
Still, nice of the uber-rich to put on a show for the rest of us.
My Kawasaki ZZR1400 does it big time on the over-run but only since I took the cats out.
Flame on!

Better not watch any vids of the 918 at work then.Blue short flames close to the tip, orange longer flames. If it's controlled (not wasteful fuel burning) it's limited to the short blue flame, yes? No?

But blue flames on the throttle? I know it has a different V12 in it but what's an Aventador doing differently?
