Koenigsegg Agera RS 0-400-0. Beats Chiron's time

Saw one of these at the LFSC supercar show near Chicago a week ago. Cool looking thing.

Very very impressive. The Agera design is getting long in the tooth and I think the Regera design was much needed and a very nice design. The simulated figures for the Regera will be even more ridiculous than that time put up.

 

One of my favorites. True supercars from the last place you'd expect them.

 

Crazy! 33.87sec and top speed 277.9 mph.

That 277.9 mph was average two way. Each way was 284.55 mph downhill and 271.19 mph uphill!!!

Awe inspiring machine. Really cool owner for letting Ksegg do all this with his car, as well.

 

Will be interesting to see if this will hold when/if Hennessey can get his new car to run...

 

At least this time the Hennessey would be considered a production car since the engine and chassis are custom (not LSX and Lotus).

 

WELL!
I realize the best plan is to keep it on the straight & [narrow], but although pretty smooth.........that's still only 2 lane blacktop! That sagebrush was goin' past pretty quickly........look like some cable safety fencing too....ouch!
Color me impressed! with the driver, as well as the car........

 

That is crazy. It looks incredibly stable at 200mph when they backed off after the last run. You can hear them celebrating a little at that speed, lol (around the 5:23 mark).

 

Congratulations to the Koenigsegg team. They did fantastic job and it's not over yet!

 

...km/h...Bugatti Chiron ---- Koenigsegg Agera RS
...0-400: ---------32,6s ------------------- 24s
...400-0: -- 9,36s @ 491m ------ 9,29s @ 499,3m
0-400-0: 41,96s @ 3.112m ---- 33,29s @ 2.239,5m

 

That's a massive acceleration difference, almost 9 seconds.

 

Wow. That is a great achievement, it seems so stable up at the scary speeds.....and it makes 140 mph seem SO SLOW!!!

 

The coolest thing about the video is that it looks like the driver is not putting the hammer down until they are well in the 100's. Then that speedo JUMPS. Wow!

 

Hmm...I started looking up what the speed of the Michelin tires could do and Andy Wallace said it's around 280, but not 300 yet. One thing that caught my attention in the article on the Chiron is the valve stem cap at high speeds. It weights 2.5 grams, but at 261mph has 16 lbs of force when rotating at that speed...and exponentially increases at speeds faster than that. Could that be the reason the Koenigsegg was having vibrations at very high speeds? I wonder if they could move the valve stem cap to the center of the wheel like Alpina has done with their wheels for a while to avoid that mass being peripherally placed.

Here's the article on that: https://jalopnik.com/why-the-bugatti-chiron-probably-wont-hit-300-mph-1796418643

 

There was an Instagram post about them testing the Agera wheel and brake and bearings over 300mph. The tpms sensor weight changes incredibly as well.
