Twin Turbo 5.5 V8 AMG
Hey Guys, this is something we have just received in OZ
MERCEDES IS JUST CATCHING UP TO YOUR C-63 !!!!!
MERCEDES IS JUST CATCHING UP TO YOUR C-63 !!!!!
Less is more for new Benz engines
Blown it: Mercedes-Benz has opted for dual turbos for its new 4.7-litre V8 - one of two new engines announced by Benz.
Mercedes pumps up V8 performance and economy with smaller, hi-tech turbo engine
10 May 2010
By RON HAMMERTON
MERCEDES-BENZ has turned to turbocharging, state-of-the-art fuel injection systems and low-friction design for a new, downsized 4.7-litre V8 engine that cuts fuel consumption by 22 per cent and yet increases power by 12 per cent over the 5.5-litre engine it is set to replace.
The Stuttgart car-maker has also announced a new narrow-angle 3.5-litre V6 petrol engine that will make significantly more power and torque while delivering a 24 per cent fuel economy improvement over the existing unit.
Both engines will debut in the Mercedes range later this year, with the V8 set to appear in the new CL500 due in the third quarter.
The move to a smaller V8 at Mercedes comes just a month after its performance arm, AMG, announced that it, too, was downsizing its big-bore bent eight from 6.2 to 5.5 litres. That twin-turbo engine, packing 400kW, will also debut in the AMG’s hot-shoe CL-class variant in the fourth quarter.
The mainstream 4.7-litre V8 – actually 4663cc – is 15 per cent smaller than the current V8 used in a swag of Mercedes models, including the E-class, S-class, CLS and ML and GL SUVs.
Power is up from 285kW from the 5.5-litre unit to 320kW in the new engine, and yet fuel consumption is down from 12.3 litres per 100km to an impressive 9.5L/100km in the forthcoming CL.
By comparison, BMW’s 4.8-litre V8 develops 270kW and drinks between 10.3L/100km and 12.9L/100km, depending on the application, while Audi’s 4.2-litre V8 makes 302kW and returns between 11.9 and 14.6L/100km.

Low pressure, 0.9-bar turbochargers – one on each bank of cylinders in the alloy block engine – are among the keys to the Mercedes V8’s impressive figures.
Mercedes says the blowers have been configured for high torque at low engine speeds, with maximum torque of 700Nm kicking in from just 1800rpm to 3500rpm. Tellingly, 600Nm of torque is available all the way from 1600 to 4750rpm.
Mercedes claims no perceptible turbo delay and the driving feel of a naturally aspirated 7.0-litre engine.
Fuel savings are aided by third-generation direct injection using piezo injectors with spray-guided combustion.
Idle-stop saves more fuel by cutting the engine at the traffic lights, while the load from ancillary equipment on the engine has been cut with adoption of the latest pump technologies for water, oil and fuel, plus an “intelligent” generator.
The new V6 has a cylinder block V angle of 60 degrees, compared with the current unit’s 90 degrees.
Mercedes says this allowed it to dispense with the counter-rotating balance shaft without loss of refinement.
Unlike the V8, the new V6 is normally aspirated and retains the same 3.5-litre displacement as the current powerplant, but still manages 25kW more power, to 225kW at 6500rpm, 20Nm more torque, to 370Nm from 3500 to 5250rpm, while slicing fuel consumption to 7.6L/100km in the S-class – a saving of 24 per cent.
The V6 – which Mercedes says can be turbocharged – features similar advances in injection technology to the V8, along with a variable-resonance induction system and revised exhaust.
Both engines also use multi-spark ignition, allowing up to four sparks in a millisecond for improved combustion.
Hand in hand with improved fuel consumption, both engines emit less carbon dioxide. In the case of the V8, CO2 is down 22 per cent, from 288g/km to 224g/km in the CL500, while the V6 notches up a 24 per cent improvement, to 177g/km.
Mercedes says its V engines have been subjected to 52,000 hours of test-bench trials and seven million kilometres of on-road testing.

Mercedes-AMG downsizes V8
Small is big: Mercedes-AMG is pinning its hopes on a twin-turbo 5.5-litre V8 for its new road rockets, including the new S63, shown here in historic 1971 racing livery.
Smaller, more frugal but more powerful 400kW V8 to power next Mercedes-AMGs
8 March 2010
By MARTON PETTENDY
MERCEDES-AMG will dramatically downsize the displacement and consumption of its staple big-bore V8 this year when an all-new and substantially more powerful petrol engine replaces AMG’s 6.2-litre bent eight.
The new 5.5-litre engine, revealed just before last week’s Geneva motor show opening in a new S63 AMG concept car, will make its debut in the facelifted CL-class coupe, which will echo the CLK-replacing E-class Coupe by being named the S-class Coupe when it goes on sale in Australia in the fourth quarter of this year.
Set to continue with a ‘63’ model designation despite its smaller capacity, the new AMG V8 incorporates direct fuel-injection, double overhead camshafts and, marking a return to forced induction and a departure from an engine AMG claims is the world’s most powerful naturally aspirated V8, a pair of Garrett turbochargers.
Peak power is quoted at 400kW at 5500rpm (versus 386kW ay 6800rpm for AMG’s current 6.2 V8), while maximum torque increases by a more substantial 170Nm, from ‘just’ 630Nm to a massive 800Nm between just 2000rpm and 4500pm – rather than at 5500rpm in the 6.2.
An even more hairy-chested version of the new ‘M157’ V8 will also be offered as a ‘Performance Package’ upgrade, at least overseas. It delivers no less than 420kW and 900Nm – the latter from just 2500rpm – but will not be available in Australia.
While the ‘garden-variety’ 400kW V8 employs air-to-water intercooling with maximum boost pressure of 1.0 bar, the 425kW version delivers 1.3 bar of boost pressure, also aided piezo-electric injectors.

While the ‘garden-variety’ 400kW V8 employs air-to-water intercooling with maximum boost pressure of 1.0 bar, the 425kW version delivers 1.3 bar of boost pressure, also aided piezo-electric injectors.
Fitted to the S-class, the M157 delivers 0-100km/h acceleration in a claimed 4.5 seconds, or 4.4 seconds in high-performance guise – up to two-tenths quicker than before.
At the same time, the M157 incorporates an idle-stop function and cylinder shut-down technology like that fitted to other Mercedes models to reduce average fuel consumption by a massive 25 per cent - or a whole four litres per 100km - compared to the current S63.
It’s claimed to return just 10.5L/100km in the newest S63, while average CO2 emissions are stated at 246 grams per kilometre.
Weighing just 204kg, the 747cc-smaller new biturbo V8, which is built at AMG's facility in Affalterbach, will be mated as standard to a variation of the seven-speed MCT Speedshift automatic transmission with wet start-up clutch, as seen in the SL63 and E63.
Rather than being related to Mercedes’ current M155-series 5.5-litre V8, AMG’s new engine is based on a new twin-turbo 4.6-litre V8, codenamed M278, that will become available in the S-class and new CLS-class globally later this year.
Officially, the M157 is not a direct replacement for the current 6.2-litre M156, but is designed as another engine option for AMG customers, which can also select the 450kW/1000Nm 6.0-litre twin-turbo petrol V12 that powers the S65, SL65 and CL65.
A naturally aspirated version of the M157 is also rumoured to power the next generation of smaller AMG models such as the C-class, but GoAuto understands either the atmo or biturbo 5.5 will eventually replace the atmo 6.2 in every AMG model, including the C63, E63, CLS63, S63, CL63, SL63 and ML63.
As well as following an industry-wide shift towards smaller-capacity forced-induction powerplants, the move mimics BMW’s shift from a 5.0-litre V10 to a twin-turbo 4.4-litre V8 for BMW’s largest M models.
The TTV8 also marks the first force-fed V8 from Mercedes since the supercharged 5.4-litre V8 that preceded the 6.2 V8. A dry-sump, freer-breathing variation (M159) of the first AMG V8 to be fully designed in-house also powers this year’s SLS AMG super-coupe.
The S63 concept revealed pre-Geneva was draped in the livery of Mercedes’ 6.8-litre 1971 300SEL AMG racing car and appeared with a number of styling cues that are likely to feature on AMG’s updated S63, including even more prominent side sills and rear wheel-arches.
"With the new AMG V8 biturbo engine and the AMG Speedshift MCT seven-speed sports transmission, we are confronting the challenges of the future and focussing on fuel consumption and exhaust emissions even more intensively than before," said Mercedes-AMG chairman Volker Mornhinweg.
"Our new high-performance engine shows that AMG occupies a leading position in terms of both efficiency and our brand commitment to performance."

I always thought they would leave the 63 engine in the C-Class since it still has room to grow (in terms of power) in the C63. They can easily boost it to 500 hp or 550 even

My 07 S63 AMG lease is due in November. Do you guys think the new S63 AMG will be in the showroom by that time?

looking for an AMG
I believe the S63 was announced as the first car this new engine would be in. I had heard from articles that it would be this summer so if they are correct. It should be there in and around November.

The issue isnt which is the better engine, the real question is will it be fitted to the C Class AMG and if so, when ?

Here is a conversion for those who do not know what the Nm and Kw numbers are.
Peak power is quoted at 400kW ( 536.19hp)at 5500rpm (versus 386kW (517.42hp) at 6800rpm for AMG’s current 6.2 V8), while maximum torque increases by a more substantial 170Nm (125.38ft. lb.), from ‘just’ 630Nm (464.66ft. lb.)to a massive 800Nm (590ft. lb.)between just 2000rpm and 4500pm – rather than at 5500rpm in the 6.2.
An even more hairy-chested version of the new ‘M157’ V8 will also be offered as a ‘Performance Package’ upgrade, at least overseas. It delivers no less than 420kW (563hp)and 900Nm (663.80ft. lb.)– the latter from just 2500rpm – but will not be available in Australia.

2009 C63 with Eurocharged tune and charcoal delete
[quote=AlexCim;4071020]The change is about emissions, not power.
Agree. I would bet almost anything that the next AMG C-Class will end up with a tuned atmo version of the M157. Probably good for over 400hp and 400 torques (as Jeremy Clarkson says) but with waaaaaaay better fuel economy and emissions than our 6.2 . It's still gonna be fast, it just wont be as much fun as our cars. Unless they somehow manage to squeeze the TT5.5 into the C-Class and "allow" it to give well over 500hp (which I think is highly unlikely in today's green world) I will be perfectly happy to drive my C63 for quite some time.
