Default The Koenigsegg Agera RS Engine

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

Quote:
...Sitting to the side of the production line is our engine workshop, where every Koenigsegg engine is hand-built by Mats, the guy who’s built every Koenigsegg engine in the last 4 years. Mats has been building engines all his adult life, most notably racing engines for motorcycles. He knows things about power.

So what is Mats building for Chassis 7128?

The Agera RS features Koenigsegg’s 90-degree, twin-turbocharged V8 engine that produces 1160hp at 7800rpm (redline at 8250rpm) and 1280Nm of torque at 4100rpm. That’s 232hp per litre of displacement. We refer to it as the ‘most downsized’ engine in the world because of this hp-per-litre figure. It’s a robust and extremely powerful engine and it is, in many ways, the core of what we do here at Koenigsegg. Our cars can do what they do primarily because of their power, handling and aerodynamics. We’ll deal with handling and aerodynamics later, but for now, let’s take a closer look at different elements of the Koenigsegg power plant....

I remember watching a doco on there factory, amazing stuff and for such a small engine to produce that sort of hp.

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.

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

MB with the power of the engine and fact that he was doing a high speed run with huge temps at speed for the tyres, he was ensuring tyre temps were kept at a minimum early on and only when at speed and needing to get momentum did the driver unleash WOT at a speed that the tyres would not have got uhmm too much of an unnecessary workout

Absolutely, while they were there they also broke their 0-400-0 time aswell.

Yeah but that's no fun....

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.

Wonder why Guinness wasn't there ?...

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.

It's basic architecture is coyote (like) which is very much a part of the modular family.

You see it immediately in bore spacing.

pretty much. From the link in the original post.

We started with that we thought was a relatively simple approach – using an existing modular Ford V8 engine and supercharging it – but it quickly turned into something much more complicated. It turned out that most attempts to improve performance in this type of engine required race fuel in combination with an open exhaust, no catalytic converters and open crank case ventilation. And even with this setup we experienced limited reliability, etc. This would not work at all for an homologated, emission controlled road car that had to be reliable enough to be driven on a daily basis on regular fuel AND at the same time be the most powerful production car in the world. We therefore had no choice but to become experts in engine design, calibration, tuning and construction – and all within a very short time frame.

We had to figure out how to design and build many of the components and systems ourselves to make the engine work. We had to re-design camshafts, pistons, connecting rods, block reinforcements, fuel injection systems, fuel pump system, drysump lubrication, a new type crank case gas re-circulation system, exhaust, patented catalytic converter flow system, compressor system, flywheel, piston oil cooling, clutch, programming etc. And we got it done. The engine used in the CC8S was truly unique and we managed to snatch the Guinness World Record for the most powerful production engine in the world – beating the legendary McLaren F1, which had held the record for the previous 8 years.

The 90-degree V angle from our original engine and bore spacing remains today, but little else. In fact, our modern engines have been so extensively re-designed over the years that we are more than comfortable calling them our own. We have our own engine designer, Thomas, whose job involves optimising every component of the engine. It’s constantly evolving, piece by piece, to become more powerful, more robust and more efficient.

yeah its still a modular just because you add a ton of aftermarket or in house parts don't change that fact

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...

Of course power will always make you faster but power to weight is a totally different metric when it comes to outright top speed.
These things are not weight weenies, it would be easier to pull the carpets from a bugatti than add 300hp.

Have you seen what the tyres cost? Not much wrong with them, I believe michelin/bugatti recommend a limited number of top speed runs before changing.

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

So around 30,000 hp for 900km/h sounds about right when you look at bloodhound.
