Mercedes king of V8's 6.3L

[Deanodriver]

I wonder how the 6.3 sounds compared to the 5.5?

I love the sound of the 5.5 in the CLS55, you see

Mercedes-Benz CLK 63 AMG
DaimlerChrysler Press Release
A new top V8 model is making its debut in Geneva in the form of the CLK 63 AMG. The 100% AMG-developed 6.3-litre V8 engine under the bonnet promises a truly memorable driving experience. Available in both Coupe and Cabriolet guise, the CLK 63 AMG eclipses the power and torque figures for any other model in this segment with a maximum output of 354 kW/481 hp and 630 Newton metres of peak torque.

Compared to its predecessor, the CLK 55 AMG, power has been upped by 84 kW/114 hp (+31 percent) and torque by 120 Newton metres (+23 percent) in the CLK 63 AMG. With new AMG high- performance composite brakes, a new AMG sports suspension, new AMG 18- inch light-alloy wheels plus exclusive and dynamic standard appointments, the new CLK 63 AMG is the sportiest and most elite CLK to date.
The new AMG 6.3-litre V8 engine delivers truly explosive performance: the CLK 63 AMG Coupe sprints from standstill to 100 km/h in 4.6 seconds (predecessor: 5.2 s), with the Cabriolet taking 4.7 seconds (predecessor: 5.4 s). The electronically limited maximum speed is 250 km/h. The majestic power delivery of the Mercedes-AMG V8 engine permits either electrifying acceleration or relaxed cruising in a high gear with ample power reserves. The new 6.3-litre V8 engine from AMG is the first in the world to combine the high-revving concept with a large displacement. Developed exclusively by AMG, this high-performance engine delivers 20 percent more torque than comparable naturally aspirated engines with a similar power rating.

AMG V8 naturally aspirated engine with an array of high-tech features Made entirely from high-strength aluminium, the V8 naturally aspirated engine is packed with a wealth of fascinating racetrack technology that reflects AMG's rich motorsport heritage. The vertical arrangement of the intake and exhaust ports together with the sophisticated new variable intake manifold featuring two integral throttle flaps results in superlative cylinder charging.
The use of bucket tappets in the cylinder heads paves the way for a stiff valve train and therefore high engine speeds. Variable camshaft adjustment, an extra-rigid closed-deck crankcase and cylinder walls with a revolutionary new LDS coating are further attributes of this ultra-sophisticated V8 engine made by Mercedes-AMG.

This unique combination of a fast-running design and a large displacement achieves the best of both worlds: exhilarating high-revving flexibility accompanied by high pulling power at low engine speeds. The decidedly sporty character of the CLK 63 AMG manifests itself in the form of tremendous agility and dynamic responsiveness across all engine speed ranges. The new AMG V8 delivers 500 Newton metres of torque to the crankshaft as low down as 2000 rpm, while the maximum of 630 Newton metres is on tap at 5000 rpm.

The new AMG V8 unit promises dynamic acceleration, instantaneous pickup and sheer driving pleasure at the highest level. With its new, sporty AMG soundtrack which was fine-tuned during an extensive series of tests, the eight-cylinder powerpack from Affalterbach offers all the spine-tingling excitement of a high- revving V8 naturally aspirated engine that makes its presence both heard and felt at any engine speed.

German law, they have to round up

Sorry, should've read every post before I posted

Me too!!! :1syellow1
The bellow and wail this thing made was just awesome.
The ride just didn't last long enough.. :

Years ago my old Dad (gone to the north bar now) had a 450SEL 6.9, as you do when you're a mad German bugger. He even put the AMG front and rear spoilers on it, looked wicked.

It did 110kph in first, 170 in second and whatever you could wind her out to in third. A standard 450 SEL's speedo went to 240kph. The 6.9's speedo goes to 260kph.

They ran a dry sump setup, held around 16-18 litres of oil if I remember. You could get 20mpg out of it at 110kph on a trip if you had the patience.

It was the safest long distance cruiser I've ever been in. Bloody thing would cruise on the old ton, and still have plenty in reserve.

It's still not confirmed though, so no one really knows. Doesn't matter what they say anyway, you can bet it will pack more, just like the old Cobra did (they claimed 390hp, but it had more like 425).

Why is everyone saying its not confirmed? Ford stated a while back that its gonna have 475hp (go to their US website). Ok i'l just post a link:
http://media.ford.com/newsroom/featu...?release=22364

And i dont kno why merc got this new V8 for? the old supercharged V8 had 350kw, yet had more torque.

The new 6.2 is an AMG only engine. AMG made the whole thing themselves, its unique to them.

At 380kW, it's also the most powerful naturally aspirated production V8 in the world.

[Iphido]

At 380kW, it's also the most powerful naturally aspirated production V8 in the world.

Only just tho, the 7.0 in the corrvette makes ~375kw. There are some others around that make simular power in some form or another. I expect it to have some competition.

I just really don't get the V12's anymore in german cars now that the V8's (and V10's) are as powerful or more powerful.

Surely this power war is going to end pretty soon.

Remember the 450 SEL? well it was eventually replaced.. and in the 1980's V12 mercs were lucky to see 180Kw from a 5.6L!! Yep standard BA six cylinder falcon has more power than a top of the line merc..


Surely we aren't going to have dozens of 700-800 Hp vechicals on the road and driven out of dealerships?

Imagine it with a Zorst, CAI and a Tune... :sm_drool:

Yes and Mount Everest really makes the local hill here look pretty limpwristed. Comparing a 25+ year old car to a current one is just a little bit silly isn't it! ? :

This new AMG unit is a stormer - I'd even go so far as saying it is the best "mass market" V8 engine in production right now, and would probably give a number of specialist ones a fair touch up too.

Agree on the V12 thing in sedans, it seems a bit pointless for the application. However, in a supercar, that's a different story - I wouldn't dare imagine a Zonda or Murcielago with anything BUT a V12!

And remember the 300SEL 6.3, the predecessor of the 450SEL? It had more power and was a quicker car to 100kph and quicker down the 1/4. The 450SEL was a more refined vehicle (as would be expected with evolutions), in the same way the 560SEL was to the 450 and with that refinement came improved safety features.

Benz's are bulletproof and built like no other. Unlike nearly every other manufacturer they design and construct EVERYTHING. Eg gearboxes, diffs, brakes. When they put a car together the body is galvanised, the whole underbody is sprayed in PVC and all seams get another coat! This thorough attention is reflected right through 'em. I remember aound 1993 BMW advertised their new 3 series design cost 100 mill. Mercedes Benz spent this on designing the rear suspension alone! Mind you Mercedes used the same luxury suspension design on C, E, and S classes where other Euro manufacturers compromised on cheaper models.

The biggest problem out here is they are not recognised for what they are. A luxury car first, sports car second. The E55 will in my opinion satisfy almost anyone who drives within their limits on the road. If you like circuit work then go an M3.

Barry V are you undermining that quote or backing it up with factual info. That is a seriously small no. of complaints. If you haven't seen the quality of the internal parts of a mercedes engine or paid any attention to their structural integrity I'd shut up. The engine components have a very high chromium and nickel content and I've seen many an engine with 400,000 with acceptionally low wear to valve train components.

only recently have mercedes begun putting the quality back into their cars (starting with the CLS). The previous model S class and many others were plagued with many issues. It is well known. the reason why it was so bad was the cut backs and budget contraints they had on each car, previous models never had some constraints. a simple google search will show this.

p.s don't be rude and tell someone to shut up when they clearly have proof, it is a forum, he is entitled to put his opinion without you resorting to personal attacks.

HAHAHAHA! Mercedes king of the V8, they don't deserve that title.

[Barry_v]

MrLandaus 302 windsor has done that (and more) and still made 100 something kw on the dyno and no rattles. The internals of a stock windsor aint nothing special. so you'd want your mercedes to last over a million if their internals are so much superior.

a babied luxury car's v8 engine lasting 400,000 is not all that impressive. I service quite a few tradesmans hiluxs with over that. I had one the other week with an aftermarket turbo fitted and the engine was still going at 450,000.

They are "so much superior" to a Ford V-8, but I don't expect my engine to last a million miles.

[nb_351]

its just a case of you get what you pay for really, everynow and then there are exceptions to the rule... i serviced one not long ago, just a clk500, 5lt 8, and it had everything, including electric dash displayed oil level gauge... and one of the new bmw engines, i think, has baffles and oil pumps in the rocker covers, aswell as gforce meters fitted to the motor, so when they are caining around nurburgring, autobahn and the like, they dont starve them of their precious oil around high intensity corners, now thats where the money goes... and things like o2 sensers on each extractor on the m3 i think... as with the general feeling though, youd want it to last 1 million ks...
