<< Prev Page 2 of 3 Next >>  The versatile AMG 4.0-litre twin-turbo V8 engine in the E 63 S 4MATIC+ takes peak performance to a new level at 450 kW (612 hp). Maximum torque attains a new best value of 850 Nm. It is available over a broad engine speed range of 2500 to 4500 rpm and so provides a feeling of effortless superiority in every accelerator pedal position. A sprint from zero to 100 km/h is absolved in 3.4 seconds, and this dynamic acceleration only ends at the governed top speed of 250 km/h (with AMG Driver's package: 300 km/h). The E 63 4MATIC+ is rated at 420 kW (571 hp) and has 750 Nm of torque. This variant accelerates to 100 km/h in 3.5 seconds.The advanced AMG 4.0-litre V8 biturbo engine utilises well-proven twin turbocharging, with the two chargers not located outside on the cylinder banks, but rather between them in the V of the cylinders. The advantages of the "hot inner V" are a compact engine design, an immediate response from the twin-scroll turbochargers and low exhaust gas emissions thanks to optimum air flow for the close-coupled catalytic converters. Two twin-scroll turbochargers are deployed for the first time to boost performance and improve responsiveness further. The housing is divided into two parallel flow passages. Combined with two separate exhaust ducts in the exhaust manifold, this makes it possible to control the exhaust gases on the turbine wheel separately. The exhaust gas from the first and fourth cylinders of the cylinder bank is fed into one duct and exhaust gas from the second and third cylinders to the other duct. The aim is to prevent the individual cylinders from having mutually adverse effects on the gas cycle. This reduces the exhaust gas back pressure and improves gas exchange. The results are increased output due to improved cylinder charge with fresh mixture, more torque at low revs and very immediate response times. Other engine measures include new pistons, an optimised air intake and charge air cooling, as well as extensive software developments. Spray-guided direct petrol injection with piezo injectors, the all-aluminium crankcase, the four-valve-per-cylinder design with camshaft adjustment, air-water charge air cooling, alternator management, the ECO start/stop function and the gliding mode have all been retained. To sum up, the eight-cylinder engine thrills with its exceptional power delivery and powerful acceleration in all engine speed ranges combined with maximum efficiency for low consumption and emission values. For maximum efficiency, Mercedes-AMG has equipped the V8 engine with the AMG Cylinder Management cylinder deactivation system. This already helped the SLK 55 to achieve impressively low consumption and emission values and is now being used with a turbocharged engine from the high-performance sports car brand for the first time. In the partial-load range cylinders two, three, five and eight are deactivated, which crucially lowers the fuel consumption. With combined fuel consumption of 8.9 litres and CO2 emissions of 203 grams per kilometre (combined), the E 63 4MATIC+ and E 63 S 4MATIC+ set a new best by comparison with their competitors. When the driver has selected the "Comfort" transmission drive program, the cylinder deactivation system is available in the wide engine speed range from 1000 to 3250 rpm. The AMG main menu on the instrument cluster informs the driver whether the cylinder deactivation system is in use and whether the engine is presently operating in the partial or full-load range. The transition from four to eight-cylinder operation is immediate, fast and imperceptible, so that the passengers do not experience any loss of comfort. This is made possible by intelligent interaction between the high-performance engine management system and CAMTRONIC valve lift adjustment, which is familiar in a similar configuration from the four-cylinder engines. There are eight dual actuators involved in half-engine mode, which operate the axially sliding cam units of the intake and exhaust camshafts via a shift gate. Half-engine operation is achieved by shutting off the relevant intake and exhaust valves of cylinders two, three, five and eight. This not only enables the load-change losses of the four deactivated cylinders to be reduced, but also increases the efficiency of the four remaining cylinders. The reason for this is to shift the operating point to higher loads. Both E 63 models are exclusively available with the innovative AMG Performance 4MATIC+ all-wheel drive system. This newly engineered, intelligent system brings together the advantages of various drive configurations. Torque distribution on the front and rear axles, which is fully variable for the first time, ensures optimum traction right up to the physical limit. The driver is also able to rely on high driving stability and handling safety under all conditions, whether the roadway be dry, wet or snow-covered. The transition from rear-wheel to all-wheel drive and back again is seamless, because intelligent control is integrated into the vehicle system architecture as a whole. An electromechanically controlled coupling connects the permanently driven rear axle variably to the front axle. The best possible torque distribution is calculated continuously according to the driving conditions and driver's input. The performance saloon can thus be driven in a continuously variable way from traction-oriented all-wheel drive to purely rear-wheel drive. Transitions are seamless and based on an elaborate matrix. In addition to traction and lateral dynamics, the all-wheel drive system also improves the longitudinal dynamics for even more powerful acceleration. It is still possible to drift thanks to fully variable torque distribution. This is where drift mode, part of the standard specification for the E 63 S 4 MATIC+, comes into its own. This can be activated in the "Race" drive program using the shift paddles, provided that ESP is deactivated and the transmission is in manual mode. When drift mode is activated, the E 63 S 4MATIC+ becomes a purely rear-wheel drive vehicle. Drift mode remains engaged until the driver deactivates it again. The AMG SPEEDSHIFT MCT nine-speed sports transmission is specially tuned to requirements in the new E 63 4MATIC+ and E 63 S 4MATIC+. This involved re-engineering hardware and software alike. A special software development enables extremely short shift times, fast multiple downshifts and the double-clutching function, making for a highly emotive gearshifting experience. A wet start-off clutch replaces the torque converter. This saves weight and optimises the response time to the driver's accelerator pedal input, particularly when accelerating and during load changes. The four different AMG DYNAMIC SELECT drive programs "Comfort", "Sport", "Sport Plus" and "Individual" allow drivers to extensively influence the characteristics of their E 63 4MATIC+. Key parameters are modified such as the response of the engine, transmission, suspension, steering, ESP and all-wheel drive system. Independently of the DYNAMIC SELECT drive programs, the driver has the option of pressing the "M" button to switch directly to manual mode, in which gearshifts are executed exclusively using the shift paddles on the steering wheel. The suspension set-ups can also be selected if desired. "Comfort" is the well-balanced drive program with a comfort-oriented suspension and steering set-up, as well as a fuel-efficient powertrain configuration and early upshifts - including smooth gear changes and a discreet engine sound. Cylinder deactivation, the ECO start/stop function and gliding mode are on: When the driver releases the accelerator in a speed range between 60 and 160 km/h, the clutch of the MCT transmission opens and the engine is decoupled from the powertrain. The electronics reduce the engine speed to idle level, and the motion resistance is reduced by the compression and frictional forces of the engine in overrun mode. The DYNAMIC SELECT "Sport" and "Sport Plus" drive programs are designed for high vehicle dynamics. This results from an agile accelerator pedal characteristic with direct set-up and emotively appealing shift operations with shortened shift times and double-clutching function on downshifts. The increased idle speed in "Sport Plus" mode additionally enables the vehicle to move off particularly quickly while ensuring faster acceleration from rest. The E 63 S 4MATIC+ also comes with the "RACE" drive program for highly dynamic driving on closed race circuits. Here all parameters are designed for maximum performance. The control logic for the RACESTART function is new and has been simplified considerably. In the Sport, Sport Plus or RACE drive programs, all the driver has to do is press the brake pedal forcefully with their left foot and simultaneously fully depress the accelerator pedal with their right foot. The on-board electronics will now set the optimum engine speed. Depending on requirements or the road surface conditions, the engine speed can be increased or lowered in either direction by activating the shift paddles. If the driver now takes their foot off the brake pedal, the E 63 4MATIC+ will accelerate from rest with optimal traction. The S-Model completes the sprint from 0 to 100 km/h in 3.4 seconds, whilst the E 63 4MATIC+ takes 3.5 seconds. << Prev Page 2 of 3 Next >> |
