Mercedes-Benz’s performance division has revealed a new bi-turbo V8 that produces more power with less fuel. By RICHARD BLACKBURN.

Mercedes-Benz’s renowned performance division AMG has unveiled a new twin-turbo V8 that produces more than double the power of a Ford Falcon yet uses the same amount of fuel.

The new 5.5-litre V8 will replace the normally aspirated 6.2-litre V8 that currently powers most of AMG’s express limousines, sports cars and soft-roaders.

It follows the recent industry trend towards producing more power more efficiently by employing smaller-capacity, turbocharged engines with the latest direct fuel injection technology.

..A standard stop-start system, which cuts engine power when the car stops in traffic, also reduces consumption.

The new engine puts out 400kW of power and 800Nm of torque, but uses just 10.5 litres of fuel per 100km – 25 per cent, or 4.0L/100km, less than the previous model. It will debut in Australia on the new S-Class-based coupe, the CL, in the fourth quarter of this year.

AMG says the engine will be even more efficient in lighter cars in the Mercedes range such as the C63 and E63, with fuel consumption likely to dip below 10L/100km. The engine will also be used on SUV variants.

The chairman of AMG, Volker Mornhinweg, says the new engine is “the perfect synthesis of dynamic power efficiency and the highest levels of efficiency”.

He says the company is adapting to the new emphasis on fuel efficiency and C02 emission reductions.

“Today AMG is facing a new era. We are reinventing ourselves while remaining true to our core brand values,” says Mornhinweg.
He says combining lower-displacement engines with direct injection and turbocharging has allowed AMG to meet its future emissions requirements for Europe and the United States. The car will also avoid the “gas guzzler” tax in the US.

The announcement of the new engine wasn’t all good news for Australian AMG fans. They will miss out on a high-performance version of the engine that puts out 425kW and 900Nm of torque.

The standard version of the new 5.5-litre AMG engine gets just 14kW more torque than the current 6.2-litre unit, but delivers a substantial 170Nm more torque. Critically, both power and torque are available much lower in the rev range, with peak power arriving at 5500rpm instead of 6800rpm and maximum torque available from 2000rpm to 4500rpm, compared to 5500rpm in the 6.2-litre.

The engine will propel the S-Class Coupe – which is changing its name from the CL-Class – from 0-100km/h in 4.5 seconds (or 4.4 seconds on the more powerful 425kW model).

Despite the change in engine size, Mercedes will stick with the ‘63’ nomenclature for its cars so the luxury coupe will be called the S63.

The new S63 also gets AMG’s seven-speed automatic transmission, which changes character at the press of a button. In manual and sports mode it holds gears longer and shifts 25 per cent quicker, while in ‘controlled efficiency’ mode it starts in second gear, shifts up as early as possible and uses the engine’s prodigious torque to keep the engine speed low and reduce consumption.

Other fuel-saving tricks include an intelligent generator management system, which recharges the battery with kinetic energy created when the car brakes. Mercedes says the system can save up to 0.2L/100km.

“We are justified in asserting that, with this drivetrain, AMG is offering a package that is unique in the premium class: sheer performance through power, torque and extremely sporty shifting characteristics on the one side, with the highest levels of efficiency through intelligent transmission control and state-of-the-art gasoline direct injection on the other,” Monrhinweg says.

question is will it fit in a falcon.
ultimate engine swap.

its a shame too see the 6.2 go its simply one of the best sounding and running v8's ever.

Agreed but i think its behind the 4.2L Audi V8

[Polyal]

Why did they have to bring the falcon into it? Dumbasses, you just want to kick some journo's in the balls sometimes.

Very neat looking setup though! twin turbos, guess CAT600 is onto something..LOL

I was thinking the same thing...Ford just can't buy good publicity at the moment it seems.

Mercedes-Benz’s renowned performance division AMG has unveiled a new twin-turbo V8 that produces more than triple the power of a Holden Commodore yet uses half the amount of fuel.

The new 5.5-litre V8 will replace the normally aspirated 6.2-litre V8 that currently powers most of AMG’s express limousines, sports cars and soft-roaders.

It follows the recent industry trend towards producing more power more efficiently by employing smaller-capacity, turbocharged engines with the latest direct fuel injection technology.

Edited for truth

Double the power of the falcon would mean they are talking about the i6 ?? wouldnt that be like comparing apples and oranges? The journo couldn't mention his meal ticket(holdon) now could he.....

[gtfpv]

i bet a ford falcon cost half the price of the mercedes engine :

[JC807]

not as interesting as BMW's reverse flow v8 twin turbo.

Exactly what i was thinking. Apparently the new Ferrari California has a 4.3 litre V8, which is smaller than a Falcon V8 but it goes a lot faster. Wow maybe we should have all bought Ferraris then. What a rediculously pointless comparison

[Fev]

That BMW engine is incredible, but the 400kw from that Merch lump is just insane. When will it stop!! hehe

[FPV8U]

If it has the soundtrack of the 6.2L they are onto a winner, but with a TT to play with it will still be a modders dream for big $ cars like the 6.2 is.

Mum reckons 700kw

[Rodp]

I call shenanigans on their fuel usage claims.

Tell her she's dreaming.....

[T3ts50]

So is it based on on the current Mercedes block or is it an all new design?

Rumours of AMG switching to twin turbos has been going on for a while. Sounds pretty impressive.

haha when I read Mum Reckons I instantly thought of The Castle, great movie. Thanks for givin me a laugh fellas

[JK EX CHASER]

If only GE 310 kw was 5.5 liter . is not much kw for two turbos,

[ebxr8240]

Aha 400 kw from a TT V8 ...Awsome..
That would be at the fly... Lol...

[Yellow_Festiva]

I'm guessing the 14kw increase should be 'power', not torque as stated..

Why don't they compare it to the turbo I6? What is the kw/L of the highest output 4.0 compared to this one?

If that consumption is true then that is a pretty good achievement.

[Bent8]

I blame Audi for this, when they released the 580hp TT 5.2L V10 in their RS6, the head of AMG stated that they are NOT getting into a horspower war and that the 6.2L V8 will suffice for some time to come.

How things change in such a short time!

It's great that they are sticking with V8 engines but something tells me it won't have the irresistible character of the 7200rpm 6.2L V8.

And why they're going to continue calling it a "63" is beyond me. (maybe they want to keep the heritage in their line-up)

[03wrx]

Its becoming an increasingly stupid exercise to raise power and torque so high.
Try driving the 2004 E55. Has 700nm torque. The car is unable to be driven to anywhere near its max, as the traction control just kicks in every time. Only from roll on in the dry will it have some form of traction. To me it felt like a fast but pointless car to own.

[GHO57]

E55 is fairly easy to drive, try driving the s65 amg V12 Bi-Turbo. that will make you happy in the pants. C63 has traction issues off the line too. But yeah on a track with warmed up tyres it would be alright.
