El nuevo V8 5.5 biturbo Mercedes Benz (S63 AMG)

[Jony]

Impresionante, y lo que queda muy claro es que cada dia son mas los autos con turbo.

[Ezequiel!]

Que barbaro como todas las marcas cada vez mas hacen downsizing con respecto a los motores. Como dice Jony de la mano del turbo se logra la misma potencia pero mucho mas eficiente con menos consumo y cilindrada.

Que exito este motor, pero como dicen arriba el 6.3 gritooon a la "old school" me puede

[fedese23]

todos los fierritos tiene.
Una belleza.

[Eduardo Bravo]

Falta guerra, JAJAJAJ no fuera de joda, es una bestia peluda esto..

Dejemonos de hinchar, la enorme mayoria de nosotros manejamos autos sub-200hp o que rondan esa cifra, y nos ponemos quisquillosos con uno de 550, yo lo acepto si no les gusta.

Obviamente que apenas me lo dan lo vendo y me compro un bimmer que aun con menos potencia, sin denominaciones ni colores raros, etc siempre van adelante y las sensaciones de manejo son mucho mejores que en un Mercedes.

q raro tanta presion, con tanta cilindrada y q rinda tan poca potencia.

como referencia un prehistorico VW 2 litros 16v con esa presion ronda los 320whp, o sea unos 360-380hp al motor.

y siendo realistas, al lado de un motor alta tecnologia como estos, con altisima compresion, inyeccion directa, y demas. digamos q la balanza se inclinaria para el lado de mercedes y bmw. extrania realmente la relacion cilindrada/potencia q logran con semejante boost.

Habria que ver el tamaño de las turbinas tambien, porque no es lo mismo el flujo de una pequeña al de una grande con misma cantidad de psi, mi auto tiene picos de 21 psi pero mi turbina es un secador de pelo, aunque asumo que por un tema de seguridad deberian ser grandes ya que por la cantidad de psi que manejan el desgaste de una turbina chica seria muy grande, sumandole a eso la presion que pierde en el circuito teniendo el watercooler... deberian ser mas los psi que desarrolla la turbina.

muy probable q sea como vos decis, una turbina chica, spool rapido.
seguramente de arriba se quede sin aire y pierda el boost y de ahi q no desarrolle gran potencia/litro.

Hay más información y fotos sobre el nuevo V8:






En el S63 AMG (donde debutará este motor), el consumo promedio homologado es de 10.5 l/100. Una cifra bajísima para un auto de equivalente a un serie 7 (más de 2 toneladas), y con un motor de más de 500 hp!!









La caja MCT no es doble embrague como suponía, sino una automática de 7 velocidades con embrague multidisco y un embrague húmedo para el arranque (que hace las veces de convertidor de par). Similar a la que equipa actualmente al C63 AMG, por ejemplo.



El comunicado oficial de MB:

Powerful and efficient: an eight-cylinder developing up to 420 kW (571 hp): Aim: Best in class – top performance in all respects by virtue of a comprehensively efficient powertrain
AMG is writing another chapter in its "AMG Performance 2015" drive system strategy: a completely newly developed AMG 5.5-litre V8 biturbo engine with a peak output of up to 420 kW (544 to 571 hp) and maximum torque of up to 900 newton metres will enter the lineup in summer 2010. The new eight-cylinder unit known internally as the M 157 impresses with a wealth of technological highlights such as direct petrol injection with spray-guided combustion and twin turbochargers.
This innovative, autonomously developed eight-cylinder power unit from Affalterbach sets new standards in terms of fuel consumption and exemplary efficiency: the new S 63 AMG, in which the V8 biturbo will have its market debut, consumes only 10.5 litres per 100 kilometres (NEDC combined consumption, provisional figure). This represents a saving of 25 percent compared to the current S63 AMG. An intelligently designed power transfer plays a major part in this: the unique AMG SPEEDSHIFT MCT 7-speed sports transmission combines dynamism with economy, and includes a new start/stop function in the "Controlled Efficiency" driving mode. The new engine/transmission combination is the epitome of exclusivity, sophistication, high performance and economy.
The S 63 AMG showcar is a homage to the impressive history of powerful AMG V8 engines: visually this high-performance saloon resembles the spectacular 300 SEL 6.8 AMG, the racing car that won a class victory and second place in the overall ranking for AMG at the 24-hour race in Spa-Francorchamps (Belgium) in 1971 – and made the company world-famous overnight.
"AMG Performance 2015" as the continuation of a success story
Mercedes-AMG is continuing this impressive story with its "AMG Performance 2015" strategy, and meeting its promise to continuously reduce both the fuel consumption and emissions of new models with the new engine/transmission combination – while reaching new heights with the central brand value of "performance".
The new AMG 5.5-litre V8 biturbo engine will play a major part in the Mercedes-AMG model strategy over the next few years. The unique AMG SPEEDSHIFT MCT 7-speed sports transmission will also guarantee a thrilling yet economical power transfer in future AMG high-performance cars. The new engine/transmission combination is another milestone in the success story of Mercedes-AMG, which began in 1967. Another highlight in the company's more than 40-year history it undoubtedly the SLS AMG: this gull-wing model due to be launched on 27 March 2010 is the first automobile to be completely independently developed by Mercedes-AMG. It means that as the performance brand within Mercedes-Benz Cars, AMG is not only fielding a masterpiece but also demonstrating development expertise at the highest level.
Direct petrol injection with spray-guided combustion and twin turbocharging
Whilst the AMG 6.3 litre V8 naturally aspirated engine has a displacement of 6208 cc the new AMG 5.5-litre V8 biturbo unit makes do with 5461 cc. The use of direct injection technology results in a reduction of exactly 747 cubic centimetres and increases efficiency. For the first time, AMG is also utilising the advantages of direct petrol injection with spray-guided combustion and piezo-electric injectors: thanks to its higher thermodynamic efficiency, this technology makes more efficient use of fuel and leads to lower exhaust emissions. AMG combines this spray-guided combustion with twin turbochargers. Other highlights include a crankcase wholly of aluminium, four-valve technology with adjustable camshafts, an air/water intercooler, generator management and a start/stop function as standard.
This high-tech package leads to a high output and torque yield, together with fuel consumption figures that are unrivalled in the competitive lineup. The AMG 5.5-litre V8 biturbo engine develops a peak output of 400 kW (544 hp) and maximum torque of 800 newton metres. In conjunction with the AMG Performance package these figures are increased to 420 kW (571 hp) and 900 newton metres. A look at the performance diagrams shows that no other engine in this output class achieves the figures delivered by the new AMG biturbo. The major difference between the two performance classes is an increase in the maximum charge pressure from 1.0 to 1.3 bar.
Quantum leap: fuel consumption reduced by 25 percent
With a provisional NEDC fuel consumption of 10.5 litres per 100 kilometres, the new S 63 AMG is 3.9 litres more economical than the preceding model powered by the naturally aspirated AMG 6.3-litre V8 – despite an increase in output by 14 kW (19 hp) resp. 34 kW (46 hp) and in torque by 170 and 270 newton metres. Engine specialists consider this achieved fuel saving of more than 25 percent to be nothing less than a quantum leap. CO2 emissions have likewise been significantly reduced: at 246 grams per kilometre, the figure is 28.5 percent lower than for the previous model.
With figures like these, the new S 63 AMG is not only considerably better than all its competitors, but also more fuel-efficient than much less powerful cars in this segment. Taking into account its enormous performance and torque figures the new AMG 5.5 litre V8 biturbo engine is in parts twice as efficient as many mid-segment or compact-class diesel engines.
At the same time the S 63 AMG delivers superior performance at sports car level: the high-performance saloon accelerates from zero to 100 km/h in 4.5 seconds, and has an electronically limited top speed of 250 km/h. The 100 km/h mark is reached in just 4.4 seconds with the AMG Performance package, with the top speed increased to an electronically limited 300 km/h.
Engine production – tradition of hand-built excellence
Like all other AMG engines, the new eight-cylinder biturbo is assembled by hand in the AMG engine shop taken into commission in 2002. A single, highly-qualified technician assembles the M 157 according to the "one man, one engine" philosophy, maintaining the very strictest quality standards. This painstaking care is attested to by his signature on the characteristic AMG engine plate.
AMG CEO Volker Mornhinweg: "Efficiency plus performance"
"With the new AMG V8 biturbo engine and the AMG SPEEDSHFT MCT 7-speed sports transmission, we are confronting the challenges of the future and focussing on fuel consumption and exhaust emissions even more intensively than before. Our new high-performance engine shows that AMG occupies a leading position in terms of both efficiency and our brand commitment to "performance," says Volker Mornhinweg, Chairman of Mercedes-AMG GmbH.
"The new AMG V8 biturbo engine is yet another milestone in our impressive V8 history. For the first time we have combined spray-guided direct petrol injection with turbocharging. With this high-tech package we are "best in class" with respect to fuel consumption, output and torque," says Friedrich Eichler, Head of Engine and Powertrain Development at Mercedes-AMG.

Exciting power delivery, characteristic sound
These on-paper figures raise high expectations which the 400 kW (544 hp) AMG 5.5-litre V8 biturbo certainly meets. The flat torque curve ensures enormous pulling power in all speed ranges: 670 newton metres are already available at 1500 rpm, and the maximum torque of 800 newton metres is delivered just 500 rpm later, remaining constant to 4500 rpm. Even more effortless performance is ensured by the engine variant with the AMG Performance package, which has a peak output of 420 kW (571 hp). In this case the eight-cylinder delivers 875 newton metres of torque at just 2000 rpm, with a constant 900 newton metres available between 2500 and 3750 rpm.
It is not only the unrivalled torque delivery of this turbocharged eight-cylinder that makes the heart beat faster, as the agile responsiveness with no irritating charger delay leads to an effortlessness and dynamism previously unknown in this output class. All perfectly matched by the characteristic, sonorous engine note. Moreover, this AMG high-performance engine naturally meets all the requirements with respect to smooth, quiet running and the comfort on long journeys that is to be expected of a Mercedes.
MCT 7-speed sports transmission with Controlled Efficiency mode and start/stop function
Power is transferred by the AMG SPEEDSHIFT MCT 7-speed sports transmission used exclusively by AMG, which is already familiar from the SL 63 AMG and E 63 AMG and combines high emotional appeal with outstanding driving dyna-mics and a high level of efficiency. The wet start-up clutch replaces a conventional torque converter, and helps to save fuel. The exemplary fuel economy is also in large measure due to the standard start/stop function. This system is active in the transmission's Controlled Efficiency ("C") mode, and switches the eight-cylinder engine off when the car comes to a stop. In "C" mode the sports saloon always starts off in second gear, and the transmission shifts to the next, higher gears at a decidedly early stage. With its high torque at low engine speeds, the V8 engine encourages a smooth, effortless driving style.
The eight-cylinder biturbo engine also features the generator management system familiar from the E 63 AMG: whenever the engine is on the overrun or when braking, kinetic energy is used to charge the battery rather than being wasted as heat in the usual way. In all other operating modes a combination of onboard network and generator management enables the generator to be kept at a low voltage. This reduces the load on the engine and makes for fuel savings of around 0.15 litres per 100 kilometres according to the NEDC standard, and up to 0.2 l/100 km in city traffic with its frequent overrun and braking phases.
Long tradition of powerful AMG V8 engines
Powerful eight-cylinder engines are an integral part of AMG's history. 2005 saw the debut of the AMG 6.3-litre V8 engine known as the M 156. Depending on the model, this naturally aspirated, high-revving unit develops up to 386 kW (525 hp) and 630 newton metres. Reserved exclusively for the new SLS AMG, the M 159 with the same displacement of 6.3 litres has a peak torque of 420 kW (571 hp) and maximum torque of 650 newton metres. Another milestone in the history of AMG engines was the supercharged AMG 5.5-litre V8 engine introduced in 2001: the M 113 K developed up to 428 kW (582 hp) and 800 newton metres of torque. Even more power was forthcoming from the supercharged AMG 5.5-litre V8 engine of the SLR McLaren dating from 2003 – the M 155 generated up to 478 kW (650 hp) and 820 newton metres.
The supercharged AMG 5.5-litre V8, the AMG 6.3-litre V8 and the AMG 6.0-litre V12 biturbo were all able to win the Best Performance Engine category in the International Engine of the Year Awards.
The first AMG four-valve V8 accelerates "The Hammer" to 303 km/h
Another important engine in the AMG story was the M 117, its first eight-cylinder unit with four-valve technology. With a displacement of 5.6 litres, 265 kW (360 hp) and 510 newton metres of torque, this V8 accelerated the 300 CE 5.6 AMG to a top speed of 303 km/h in 1987. This made the coupé the fastest German car in series production, and American fans reverently christened it "The Hammer".
The S 63 AMG showcar harks back to the historic success in 1971
A historic success was achieved by the 300 SEL 6.8 AMG in 1971: powered by an AMG V8 engine with a displacement of 6.8 litres and developing 315 kW (428 hp), this signal red racing saloon crossed the finishing line in second place during its very first outing at the 24-hour race in Spa-Francorchamps (Belgium), securing victory in its class.
The spectacular S 63 showcar is homage to this triumph, which made AMG world-famous overnight although the company had only been founded in 1967: decorated with sponsoring stickers identical to those on its historic predecessor, this powerful S-Class made by Mercedes-AMG is a sensation. The imposing tyres in size 275/35 R 20 and 325/30 R 20 at the front and rear are just as eye-catching as the 4.5-centimetre wider front wings on each side. The discerning car-lover will even discover exotic wood trim in the style of the original car in the interior. The showcar is powered by the new AMG 5.5-litre V8 biturbo engine and the AMG SPEEDSHIFT MCT 7-speed sports transmission.

Como movida publicitaria, MB quiso asemejar al nuevo S63 AMG con el famoso 300 SEL 6.3 que corrió y ganó a finales de los '60... pero NADA que ver!!!










Un poquito demasiado este interior para un clase S, no??!

[nico 535]

me vuelvo locooooooooo que me vuelvooooooo
ESO QUIERO YO

otro espectacular motor de este segmento, como ya hay similares en bm y vag..
pero hay algo (en realidad mucho) q no comprendo de estos motores... se q es un motor concebido para ser asi y q no valen las consignas hipoteticas pero.... si a este motor le sacaramos los turbos... seria un motor que rinde 43hp/ litro ?????? (no menos miserable la suma que saldria de la estimacion en X5/6M.. 50hp) supongo que sera un tema de curvas parejas de potencia, de bruto torque todo el tiempo, los perfiles de levas deben ser recontra suavecitos (mas aun q los d eun auto std alo que estamos acostumbrados)... pero me encataria que quien sepa de cátedra de porque un motorote de ultima generacion, multivalvular, con inyeccion directa, de tremenda cilindrada, con la compresion de un auto n/a y cargando nada menos que 1300grms! tiene "tan solo" 550hp...

el N54 en cambio si se encuentra dentro de la pobre lógica que logro entender... siendo un motor de excelente rendimiento para su cilindrada presion, suavidad, "parejidad" etc..... por otro lado... un motor q dandole un kg de presion estaria por arriba d elos 400hp tranquilamente ... no entiendo como motores de la misma generacion con casi el doble de cilindrada y mas de el triple de presion ... pueden rendir solo un 75% (aprox) mas de potencia final... excepto que en el resto de la curva lo mire desde muy arriba, pero tampoco me cierra, ya que el n54 no es un motor q sufra de falta de potencia en régimen medio.

[Coyote]

alvaro, la potencia por litro no es grande. pero el area bajo la curva de potencia seguramente es enorme.

fijate el tamanio de la turbina, si bien carga bastante presion, el caudal de la misma no es demasiado grande. eso es lo q limita la potencia final. pero una turbina con una compresora chica, levanta presion mucho mas rapido q una grande.

siendo realistas, 550hp maximo es mas de lo q cualquier sedan puede necesitar. sumado a eso, estos coches suelen todos venir limitados a 255km/h. tonces sacar mas potencia maxima, no tiene sentido.
pero si tiene sentido, sacar mas potencia a lo largo de toda la curva de potencia, cosa de q no importa en q rpms estes, tengas una potencia brutal.

[Fede-525]

IMPRESIONANTE!

Concuerdo con coyo, muchas veces no importa "tanto" la potencia final, si no como y cuando sea entregada...

Hablando de mercedes, sin comparacion igual, hace poco vi la curva de torque de la 380 SEC w126, que ya que no tengo el manual de usuario la encontre en internet asi veia bien que hay debajo de ese capo inmenso je

Me costo dos miradas ver bien que la curva de torque, propiamente casi no era una curva jajajaj

Era una cosa casi recta que lo menos que tenia era 30 kilos a nada de rpm, y lo maximo eran 32.... y despues bajaba a 30 y seguia constante...

Eso realmente hace que el auto de unos consumos INCREIBLES en ruta, porque no necesita levantar rpm para mantener velocidad (1985 12.2 l/100km a 160km/h), lo mismo que esta pequeña bestia. Seguramente podes crucear a 200km/ con un consumo de 10 litros! Debe ser increible je


Gracias martin por tanta data, me empalague de V8 MB.
