The World's Most Powerful Normally Aspirated Eight-Cylinder Engine Made by Mercedes-AMG

Mercedes-AMG has taken a completely new departure: the new AMG 6.3-litre V8 engine is the first in the world to combine the high-revving concept with a large displacement. Developed entirely by AMG, this high-performance engine has a displacement of 6.3 litres and generates an output of 375 kW/510 hp at 6800 rpm, plus a maximum torque of 630 Newton metres, which makes the new power pack by AMG the world’s most powerful naturally aspirated eight-cylinder production engine. Thanks to its large displacement, the V8 by AMG develops around 20 percent more torque than comparable naturally aspirated engines in this performance class.

Made completely from high-strength aluminium, this naturally aspirated V8 engine has a wealth of exciting features derived from motorsport, and impressively documents the successful motor racing history of AMG. Together with a variable intake manifold featuring two integral throttle flaps, the vertical arrangement of the intake and exhaust ducts ensures perfect cylinder charging. Bucket tappets in the cylinder heads allow a stiff valve train and therefore high engine speeds. Variable camshaft adjustment, a particularly rigid closed-deck crankcase and cylinder walls with a new, revolutionary LDS coating are further attributes of this ultra-modern V8 engine made by Mercedes-AMG.

The high expectations of AMG customers and the impressive history of AMG eight-cylinder engines were both an incentive and an obligation for the engineers and product planners at Mercedes-AMG GmbH to come up with a superlative new V8 power unit. A mere glance at the key technical data shows that this has been achieved: from a displacement of 6208 cubic centimetres, the AMG V8 aluminium engine develops a peak output 375 kW/510 hp at 6800 rpm and a maximum torque of 630 Newton metres which is available from 5200 rpm. The maximum engine speed is 7200 rpm.


Keys figures at a glance:


Displacement: 6208 cc

Bore/stroke: 102.2/94.6 mm

Compression ratio: 11.3 : 1

Output: 375 kW/510 hp at 6800 rpm

Max. torque: 630 Nm at 5200 rpm



This unique combination of a fast-running concept and a large displacement achieves the best of both worlds: exhilarating flexibility accompanied by high torque at low engine speeds. The driver experiences the decidedly sporty character of the engine in the form of great agility and dynamic responsiveness in all engine speed ranges. The new AMG V8 already delivers 500 Newton metres to the crankshaft at 2000 rpm, while the maximum of 630 Newton metres is on tap at 5200 rpm – more than any other naturally aspirated engine in this output and displacement class. In short, the new AMG eight-cylinder guarantees dynamic acceleration, rapid intermediate sprints and sheer driving pleasure at the highest level.


Completely autonomous development from Affalterbach


In design terms the new eight-cylinder engine by Mercedes-AMG is the first completely autonomous development to have no features or shared parts whatsoever in common with other eight-cylinder units by Mercedes-Benz. The new 6.3-litre unit differs from the other AMG V8 engines based on Mercedes designs in the distance between cylinders, the crankcase concept, the sophisticated intake and exhaust manifolds and the valve train; the bore/stroke ratio is also a completely new departure for Mercedes-AMG.

The new powerpack is produced at the ultra-modern AMG engine workshops, according to the "one man, one engine" philosophy. This means that a single technician assembles the complete engine by hand – as witness his signature on the engine’s AMG badge.

I wonder how this engine stacks up against the new 5 liter V10 in the M5...................?

GS300Rich

Great find. 510 hp Is this going in the new E series or something else?

KVA

Sweet

It will most likely come to the new E & S AMG models...and hopefully the C

AMG punched-out Mercedes V8s in the 70s and 80s... the cars were nicknamed "Hammer."

A suitable name, indeed. This is the modern day Hammer, if there ever was one!

LexFather

I assume this goes in the E and S but I am sure Brabus will stuff it into the C and everything Benz makes.

This engine sounds incredible.

If you compare the specs of this engine with the V10 in the M5, it does not seem to be so great considering that it is 1.3 liters bigger than the BMW V10. I wonder what the real world numbers will be for the MB engine. Perhaps it does not even matter in the real world............. The MB one will be no turtle in the quarter mile.

BMW V10 (in the M5) specs:

Type: V10
Displacement: 5000 cc
Horsepower: 507 bhp @ 7750 rpm
Torque: 384 lb-ft @ 6100 rpm
Redline: 8250 rpm

GS300Rich

I can imagine that engine stuffed inside a CLS

SC400Dude

Or the new SLK....

Have you seen the SLK w/ the SLR swap...

Afre you talking about that PS ?

PS? You've made multiple replies in this original thread, AmethySC.

You gotta give it to the Germans for putting such monstrous yet so technologically sophisticated pieces of machinery into their production cars. It is such expensive toys that make their brands so much more desirable than the rest.

Gojirra99

Yes, I remember that thread, & this post in it too :

XeroK00L

Argh...since when did GS300Rich add those posts to the thread without my knowledge?

My bad... Gotta pay more attention to the details before I correct others.

XeroK00L

*Ahem*...actually, on the very thread that GS300Rich linked to, people later have proved that it is a real deal after all. It's just hard to tell from the distance of the Internet anyway these days.
