The acceleration out of corners is crazy. Very perceptible. The video is almost cartoonish.

sounds pretty meaty
180hp per cylinder. Hard to find such a figure outside of drag racing...
Well roon, real big engines do easily beat it, & in motorsport, hard-tuned Reno air-race machines do too, of course..

Yes, cargo ships decimate this figure. I should have said: 180hp per cylinder is uncommon for a road car outside of drag racing.

Porsche only published onboard footage of a 1:43,5! In order to make this video I rendered their video at a speed of 102%, which shortend the 1:43,5 to approximately 1:41,7 (which is the actual new track record)





Looks like they extended the side skirts for their Spa run. Bonus points for those who can explain why the compressor has 3 pipes entering it from the airbox. Multi stage? BOV returns?

Seems to have a microtube water radiator in the left sidepod.

I see no oil radiators.

The new photos by Roon allowed me to notice something: Are the rear suspension pushrods active in some way? They sure look like more than a simple pushrod. Active ride height maybe? I think I am seeing independent left and right dampers and a third heave unit, so ride height seems like all that's left...

I have seen an information that 919 evo has rear axle steering, but I cannot find it again to confirm the source.

Is there another term for 'brake migration' control? Brake bias dependent upon pedal force/travel.

It's a brake bias that changes with speed. F1 used to have brake migration if I remember correctly, although that was purely hydraulic brakes. In the hybrids, I think the system changes the amount of brake energy harvesting to maintain balance as speed drops.
Turbo says "Dumpster sounds so much more classy. It's the diamond of the cesspools." oh, and "The Dutch fans are drunk. Maybe"

On a slower note. The new Aventador SV Jota vs Porsche GT2 RS. TOO bad they couldn't synchronise the two vids properly.

Always find the gap then use it.

It's very very easy headlines for porsche,and I dont like that.

If the ppl would make a car to drive as fast as possible around spa or nordschliefe,
Porsche 919 is damn dumptruck.


So I am happy that a F1 team heavyle bounded by rules, show the world that 919 is just a piece of ---, and nothing more than cheap way of getting attention.

Porsche did some maths and was like hej, this is easy attention.
Well good its short lived and cleaned up.


919 will only break records that are not seriously contented, so Porsche need stop bullshiting with easy headlines

Let them do something useful and let set real records, not ones that are up for grasp. Because no else cares

If ppl want they can make car that looks like a batmobile, and is twice as fast as any know car on those circuits.


But there is none interested, so there no competition.
If there is no competition there nothing to win,
So Porsche must not do like they did something special because they didn't

What you think would happens if a company like merc would build a car with no rules, then every record wil be broken......50%faster

Then you would have a real record, not something Porsche came up with
