Mercedes-Benz E63 AMG, 2014
Mercedes-Benz-AMG continues to champion performance, dynamism and efficiency: the new Mercedes-Benz E63 AMG is now available as a particularly powerful S-Model with an output of 430 kW (585 hp), 800 Newton metres of torque and featuring a newly developed performance-oriented AMG 4MATIC all-wheel-drive system. The AMG 5.5-litre V8 biturbo engine continues to be the absolute pinnacle of efficiency: the combination of high performance and low fuel consumption remains unrivalled by any other competitor in the segment worldwide. The permanent all-wheel drive is also optionally available for the other Mercedes-Benz E63 AMG models - on which the V8 engine has been uprated from 386 kW (525 hp) to 410 kW (557 hp), with 720 Nm of torque. With this range, Mercedes-AMG is premiering high-performance passenger car models with an all-wheel-drive system geared to driving dynamics.
The CLS63 AMG also benefits from the new model range constellation: similarly to the E63 AMG, the Coupé and Shooting Brake will also be available with performance-oriented AMG 4MATIC all-wheel drive. Alongside the successful SUVs - ML63 AMG, GL63 AMG, G63 AMG and G65 AMG - two passenger car model ranges comprising up to eight unique models with all-wheel drive are now available from Mercedes-AMG in the guise of the Mercedes-Benz E63 AMG and the CLS63 AMG. Additional models featuring performance-oriented AMG 4MATIC all-wheel drive, such as the A45 AMG and the CLA45 AMG, will follow in 2013.
Acceleration to 100 km/h from a standing start in 3.6 seconds provides the Mercedes-Benz E63 AMG S-Model with a comfortable lead over the entire competition; the top speed stands at 250 km/h (electronically limited). In addition to the increase in output, this is also attributable in no small part to the performance-oriented AMG 4MATIC all-wheel drive with a power distribution ratio of 33 to 67 percent (front/rear axle). Perfect traction during acceleration effectively avoids slip-induced losses.
On the new S-Model the AMG 5.5-litre V8 biturbo engine generates a maximum output of 430 kW (585 hp) and maximum torque of 800 Newton metres - representing an increase of 20 kW (28 hp) over the AMG Performance package which was previously available as an option. This enhanced performance and power results from adaptation of the engine application, an increase in peak pressure and a rise in the charge pressure from 0.9 to 1.0 bar. At 410 kW (557 hp) and 720 Newton metres, the basic model also boasts an increase of 24 kW (32 hp) and 20 Newton metres over its predecessor.
Despite added power and enhanced performance, all models of the Mercedes-Benz E63 AMG offer high efficiency, low fuel consumption and low exhaust emissions. The AMG 5.5-litre V8 biturbo engine remains the most efficient series production V8 engine around - with substantially more cubic capacity than its direct competitors. The E63 AMG rated at 410 kW (557 hp) with rear-wheel drive runs on 9.8 litres of fuel per 100 kilometres in accordance with NEDC (230 grams of CO2). The variant with performance-oriented 4MATIC all-wheel drive and the S-Model rated at 430 kW (585 hp) with all-wheel drive display only marginally higher fuel consumption, at 10.3 to 10.5 litres per 100 km (242 grams to 246 grams of CO2). As an additional boon, following the implementation of internal engine measures all E63 AMGs meet the requirements of the stringent Euro 6 emissions standard which will not enter into force until 2015.
The market launch of the new Mercedes-Benz E63 AMG with rear-wheel drive will begin in April 2013, with the all-wheel-drive E63 AMG and the E63 AMG S-Model following in June.
Engine: Top on power and efficienc
The AMG 5.5-litre V8 biturbo engine in the Mercedes-Benz E63 AMG delivers signature AMG high performance on all fronts. From top speed through torque generation, power delivery, engine sound and suitability for long trips to hallmark Mercedes reliability, the eight-cylinder engine with an output of up to 430 kW (585 hp) meets high expectations and leads the way in its segment. Today's challenges also include peak performance in terms of efficiency. The E63 AMG continues to set new standards here - the AMG 5.5-litre V8 biturbo engine remains the most efficient series production V8 engine around. A look at the fuel consumption picture confirms its outstanding credentials: running on 9.8 litres per 100 kilometres in NEDC combined mode (E63 AMG Saloon with rear-wheel drive), the E63 AMG demonstrates in impressive fashion how fascinating dynamics and low fuel consumption can be combined to perfection.
As previously, the Mercedes-Benz E63 AMG is available in a choice of two power ratings: as the basic model with an output of 410 kW (557 hp) and 720 Newton metres of torque and as the S-Model rated at 430 kW (585 hp) and generating up to 800 Newton metres of torque. This represents an increase of up to 24 kW (32 hp) and 20 Newton metres in comparison to the respective predecessor models. The technical basis for this uprating results from adaptation of the engine application, an increase in peak pressure and a rise in the charge pressure from 0.9 to 1.0 bar. The engine experts at AMG have achieved compliance with the requirements of the particularly stringent EU6 emissions standard, which will not become mandatory until 2015, by optimising the injection timing with the aid of multiple fuel injection and by modifying the European on-board diagnostics.
From power delivery to engine sound, the AMG 5.5-litre V8 biturbo engine (internal designation M 157) makes every mile a sheer delight. The E63 AMG picks up speed with effortless poise. A key factor here is the unique torque curve of the supercharged eight-cylinder engine from the AMG hand-finishing section in Affalterbach: 720 Newton metres of torque are available in the broad rev range from 1750 to 5250 rpm, the Mercedes-Benz E63 AMG S even disposing of as much as 800 Newton metres between 1750 and 5000 rpm. This results in vast pulling power in every speed range.
The technical highlights of the AMG eight-cylinder engine:
Direct petrol injection
Four-valve technology with camshaft adjustment
Air-water charge air cooling
ECO start/stop function
Two exhaust gas 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 per hour into the combustion chambers. Thanks to their special, compact design - the turbine housings are welded to the exhaust manifold - there are significant space advantages, and the catalytic converters also heat up more rapidly.
The AMG V8 dispenses with the customary blow-off valve. This has enabled an extremely compact design for the compressor housing. To ensure agile responsiveness with no time lag, all the air ducts in the intake tract are as short as possible. The AMG experts have enabled the wastegate valve, which reduces the pressure in the exhaust system during negative load changes, to be vacuum-controlled via an electropneumatic converter. This allows dethrottling under partial loads, which in turn lowers the fuel consumption.
As was already the case in the AMG 6.0-litre V12 biturbo engine, the eight-cylinder direct-injection unit uses particularly efficient air/water intercooling. The low-temperature cooler with its water circulation is space-savingly accommodated within the V of the cylinder banks. It effectively cools down the intake air compressed by the turbochargers before it enters the combustion chambers, and maintains a constantly lower intake temperature under full load. The large radiator at the car's front end ensures defined cooling of the water circulating in the low-temperature circuit. Extremely short charge-air ducting makes for optimum responsiveness. The stainless-steel pressure pipes for the fresh and charge air are produced by the hydroforming process, have a wall thickness of only 0.8 millimetres and are designed for very low pressure loss.
