I know it is from the manufacturer itself but it is such a great read.
The effort, the engineering, staggering. Quote:

Swedish hypercar sets new unofficial record averaging 447km/h on closed US highway
Koenigsegg has once again proved it makes the world's fastest car by setting a new record with its Agera RS hypercar on a closed, 17km-stretch of highway in Nevada in the US. Recording an incredible 447.2km/h (277.0mph) average on two closed runs, the Agera RS driven by factory driver, Niklas Lilja, briefly hit 457.9km/h (284.6mph) in the record attempt. The road used, a highway from Las Vegas to Pahrump, was said to have a slight elevation meaning the Agera RS, that packs a mighty 865kW/1280Nm, was fractionally faster in one direction than the other, hence why an average was taken. Despite the heroics, claimed to have taken numerous runs on just one set of Michelin tyres, the record was not independently verified by Guinness. That means the 2010 record 431.0km/h (267.9mph) speed, set by a Bugatti Veyron 16.4 Super Sport, still officially stands. Recently, Koenigsegg released a video of the same Agera RS recording a zero-400km/h-zero time of just 36.44 seconds that is said to prove the Swedish hypercar is an incredible 5.5 seconds quicker than a Bugatti Chrion. It's not known if Koenigsegg is in the process of applying for Guinness verification. |

The Bugatti Veyron SS has 626hp/tonne and managed 268mph while the Agera RS has over 830hp/tonne and only managed an extra 10mph 7 years later ! The Chiron has 730hp/tonne but has an extra 600kg to lug around... will be interesting to see if they can beat the Agera RS when they start their top speed testing early next year.

When you are doing speeds like this power to weight really means nothing.
It's all about aerodynamics. Otherwise the McLaren f1 would be a slug when you consider it has around half the power of the two beasts. 500cc gp motorbikes have better power to weight ratios than the best fighter jets yet can only pull around 320 flat chat. They also have the aerodynamic efficiency approaching that of a freight train.

unless you live under a rock you should know that the "koenigsegg" engine is basically a ford modular v8.

Maybe because it does matter and the more power you have, the more chance you have of overcoming the law of diminishing returns as you reach the limits of the cars aerodynamics and tyre integrity.... The McLaren F1 has reached 243mph with the rev limiter raised... this tells us it will go faster... it also has a similar power to weight ratio to the Veyron SuperSport which tops out at 267mph The only thing holding these cars back are their tyres and gearing...

From the inside of the car. Check out the acceleration after 300km/h

Strange how he doesn't let the engine rev until he's doing 350. Then the bloody thing just launches lol. Awesome machine!
Imagine owning a car like that, @350 I'll just sink the boot in - see ya at the pub for lunch fellas. Nice smooth bit of road too, wouldn't mind that in the back yard. No way would you get to speeds near that here.

I was amazed he found another cog after going through 300! then when he started slowing down, 200 looked like going from 110 to 60 that us mere mortals have to deal with lol

Yes. It was done a couple of hours drive outside of Vegas I believe. A lot of big names in the industry were there for SEMA

Especially when the company is paying for the tyres. Particularly if they're the same Michelin that the bugatti runs which last I heard are $28,000 a set. Then there's us mere mortals.

P = ½ * ρ* Cd * A * v^3
Power, P, required is a cubic of speed desired (v is for velocity). Double the speed, you need 2^3 = 8x the power for any given area through air (the ρ* Cd * A bit) Triple the speed, you need 27x the power... Practically, not much difference below 90 km/h, but ask any salt racer they'll talk of power, wheel spin/tyre slip and stability as things to think about the above ignores frictional losses everywhere Last edited by 383hq; 14-11-2017 at 09:44 PM. |
