mas info del nuevo motor V 8 6.3 atmosférico de AMG, como detalles relevantes son de destacar el uso continuado del magnésio en su construcción, el nuevo bloque de un ultraligero aluminio , ademas de un nuevo y patentado sistema de distribución variable (le permite tener 50 Newton a 2.000 vueltas ) ademas de nuevos tratamientos jamas aplicados al mundo del motor en coches de serie, como por ejemplo el TWAS, es un tratamiento para que el rozamiento de los pistones sea aún mas bajo. Por otra parte este motor ha sido diseñado y construido de forma autónoma por AMG, no compartiendo ningún recambio con los anteriores V 8 de Mercedes, y por supuesto siguiendo con la filosofía de AMG un único operario es el que construye cada unidad, son numerosas las patentes que han tenido que registrar para el desarrollo y construcción de este nuevo motor, donde han aplicado gran parte de la experiencia de AMG en el mundo de la competición. curva The new AMG 6.3-litre V8 engine will shortly be presented in a new high-performance AMG car, and is destined to provide both emotional and physical driving pleasure thanks to its exhilarating flexibility and high torque at low engine speeds. The V8 delivers 500 Newton metres to the crankshaft at just 2000 rpm, not far short of the maximum of 630 Newton metres that’s on tap at 5200 rpm. In short, the new AMG eight-cylinder guarantees dynamic acceleration, rapid intermediate sprints and sheer driving pleasure at the highest level. Unique variable intake manifold and revolutionary cylinder walls Apart from the large overall displacement, the extremely high output and torque is above all due to the sophisticated intake system – a completely new departure for AMG. Its major characteristics are large cross-sections, the streamlined design of the entire intake and exhaust manifolds, and the vertical arrangement of all ducts in line with motor-racing practice. The newly developed and patented variable intake manifold, which is made of magnesium and has two parallel-action internal throttle flaps, is a world first. The combined action of these components, which are highly unusual in regular engine production, ensures perfect cylinder charging. The 32 valves in the cylinder heads are operated by bucket tappets for a rigid valve train and high engine speeds – a technology which has proved its worth in motor racing. Continuous adjustment of the camshafts on the intake and exhaust sides is another special feature of this up-to-date AMG V8 engine. The interior of this powerful new development conceals yet another genuine world first, too: as the world’s first regular production engine, the AMG 6.3-litre V8 engine features a special twin-wire-arc-sprayed (TWAS) coating on the cylinder walls, a new process which produces outstandingly low friction. Motor racing genes are once again obvious in the crankcase: as in the supercharged AMG V8 engine for the Mercedes-Benz SLR McLaren, the engineers and technicians opted for a particularly rigid bedplate design with closed-deck technology. Special, cast-in steel components ensure even more rigidity, a reliable oil supply in all everyday operating situations and optimal long-term durability. 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.
está diciendo ........................"ahora es cuando la matan...." y con cara sufrimiento mete el bloque en culata
Si sumamos esto a lo bonitos que van a ser los proximos mercedes... Buffff, yo que se. Lo malo es que son conduccion para mayores de 65... Freno esponja, direccion blanda como la masa del pan, suspensiones confortables... Pero si no...............
pues para ser coche de conducción de mayores...............ya comentaron q "simple" claseC podía seguir por carreteras de curvas a un serie3....con lo cual.....las cosas veo q están cambiando...:mus-
Strap...no te esfuerzes. El otro dia postee esto...y todos coincidian en decir que esl un V8...y que por tanto, es lo mismo de siempre. Ya sabes como se las gastan por aqui.
Yo he llevado el actual C55AMG de un vecino, y el coche es genial, tiene un sonido precioso, etc... Pero la conduccion... Buf, llamadme maniatico. Lo cual no quita para que sea una bala o negocie las curvas de miedo. Pero un Fiat Stylo JTD es mas rapido que un Compact 320td en el Jarama, y que quereis que os diga... No hay color en tema de direccion, tacto del freno... Aunque sea menos eficiente.
