Emotional peak performance and enormous torque, agile power delivery and a characteristic engine sound, comfort on long journeys and hallmark Mercedes reliability: expectations are high when Mercedes-AMG introduces a new high-performance engine – and its very first biturbo eight-cylinder is no exception. Two criteria are inexorably gaining in importance, namely efficiency and economy. Mercedes-AMG is confronting the challenges of the future, and demonstrating that dynamic performance can be perfectly combined with fuel economy.
由于效率和经济性的提升是越来越重要, 为了满足越来越严格的排放标准, 同时还要保持奔驰AMG的峰值性能和巨大的扭矩，敏捷的动力输出，动听的发动机声音，舒适的长途旅行和高可靠性：奔驰AMG的开发了全新的高性能发动机 - 第一款双涡轮增压8缸发动机。梅塞德斯- AMG面对未来的挑战，表明高性能完全可以与燃油经济性结合起来。

The new AMG 5.5-litre biturbo engine combines performance with efficiency to a previously unknown extent. This is made possible by a unique combination of innovative high-tech systems such as direct petrol injection, twin turbochargers, air/water intercooling and the Controlled Efficiency start/stop function. The eight-cylinder biturbo engine will celebrate its market debut in the new S 63 AMG in September 2010.
全新的AMG 5.5升双涡轮增压发动机使性能与效率相结合达到了一种前所未有的表现。这是可以做到的创新高科技系统的独特组合，如汽油直接喷射，双涡轮增压器，空气/水的中冷器和控制效率启动/停止功能。这款全新的8缸双涡轮增压发动机将随着新款S 63 AMG的上市在2010年9月公开亮相。

4楼
Mercedes-AMG is systematically following the trend towards increasing efficiency with its new V8 biturbo engine: with a displacement of 5461 cubic centimetres it is precisely 747 cc below the 6208 cc of the naturally aspirated AMG 6.3-litre V8. Nonetheless it considerably betters it in terms of output and torque. 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 increase to 420 kW (571 hp) and 900 newton metres. The torque curve in particular shows that no other engine in this output class is able to match the figures delivered by the new Mercedes-AMG biturbo unit.
奔驰AMG是系统的提高了其全新V8双涡轮增压发动机的效率，新款双涡轮增压发动机排量5461毫升比老款自然吸气式AMG 6.3升V8引擎的6208毫升排量低了747毫升,然而在输出功率和扭矩上新5.5升发动机却大大优于老款。AMG的5.5升V8双涡轮增压发动机达到400千瓦（544马力）和800牛顿米的最大扭矩峰值输出。在安装了AMG性能包后可以将这些数字增加至420千瓦（571马力）和900牛顿米。尤其是扭矩曲线显示，没有其它同类发动机的输出可以达到奔驰AMG的这款全新双涡轮增压发动机所发表的数字。

Despite an increase in output by 14 kW (19 hp) resp. 34 kW (46 hp) and in torque by 170 and 270 newton metres compared to the naturally aspirated V8, which develops 386 kW (525 hp) and 630 newton metres, AMG engineers have been able to reduce fuel consumption and CO2 emissions considerably.

With a provisional NEDC fuel consumption of only 10.5 litres per 100 kilometres, the new S 63 AMG betters its predecessor by 3.9 litres. This equates to a fuel saving of more than 25 percent, which engine specialists consider to be nothing less than a quantum leap. CO2emissions have likewise been significantly reduced: at 246 grams per kilometre, the figure is 28.5 percent lower than for the previous model (344 g/km).

The achievement of these efficiency and environmental aims has no negative
effects whatsoever on dynamic performance. On the contrary, as the new AMG 5.5-litre V8 biturbo fully lives up to AMG’s brand commitment to “performance”: the S 63 AMG accelerates from zero to 100 km/h in 4.5 seconds, and has a top speed of 250 km/h (electronically limited). With the AMG Performance package, the high-performance saloon reaches the 100 km/h mark in 4.4 seconds and reaches a top speed of 300 km/h (electronically limited).

Combination of twin turbocharging and direct petrol injection
Mercedes-AMG is presenting an attractive high-tech package with its combination of biturbo charging and direct petrol injection with spray-guided combustion. The innovative injection technology brings decisive advantages with respect to fuel consumption and exhaust emissions, thanks to higher thermodynamic efficiency. Particularly fast and precise piezo-electric injectors spray the fuel into the combustion chambers, ensuring a homogeous fuel/air mixture and highly effective combustion.

Two turbochargers and efficient air/water intercooling
Two turbochargers located next to the cylinder banks supply the eight cylinders with fresh air. At their maximum speed of 185,000 rpm under full load, the two turbochargers force 1750 kg of air into the combustion chambers per hour. The maximum charge pressure is 1.0 bar, and 1.3 bar with the AMG Performance
package. Thanks to their specific, compact construction – the turbine housings are welded to the exhaust manifold – there are significant space advantages and the catalytic converters also heat up more rapidly.

The new AMG V8 is the first turbocharged engine to dispense with the usual blow-off valve. This neat solution enabled the compressor housing to be made extremely compact. To ensure agile responsiveness with no time lag, all the air ducts in the intake tract are as short as possible. The wastegate valve, which reduces the pressure in the exhaust system during negative load changes, is vacuum-controlled via an electropneumatic converter. This allows dethrottling under partial loads, which in turn lowers the fuel consumption.
