With most of the info on the high-performance E63 AMG already available, Mercedes officially unveiled the 518hp monster E-Class at the New York Auto Show today.
The new model retains the 6.2-liter V8 found in the previous generation, and gets just a slight bump (of 11hp) in performance to 518hp and 465 ft-lbs of torque. To help get that power to the ground AMG has equipped the car with the new AMG Speedshift MCT 7-speed automatic transmission, first used in the SL63. Using a multi-disc wet start-up clutch, instead of a traditional torque converter, shift times are just 100 milliseconds in “M” (Manual) mode.
Another reason for the speedy shift times is that AMG has programmed the ECU so that under full load gear shifts, the ignition and fuel injection are interrupted.
The engine and tranny combine to deliver a 0-60 mph time of just 4.4 seconds!
Oh, and the the transmission does rev match on the down shift and have a Race Start or “launch control” function.
In total the transmission has four settings: C” (Controlled Efficiency), “S” (Sport), “S+” (Sport Plus) and “M” (Manual).
The Controlled Efficiency setting also works with several other technologies to reduce overall fuel-consumption by 12 percent compared to the previous model. The Controlled Efficiency mode will give early up-shifts to keep engine speed as low as possible, while AMG has developed a way to “detach” the alternator from the engine so that it doesn’t drain power when it isn’t needed.
The body of the E63 is 17mm wider than the standard E-Class with a front track that is 2.2-inches (56mm) wider.The front suspension has been completely redesigned by AMG engineers with new control arms, wheel bearings, a new stabilizer bar. This new setup actually moves the location of the wheel to provide better handling and more negative camber.
As a result of the wider setup, the steering ratio is now 22 percent more direct and boasts a sporty 14:1 ratio.
The suspension of the E63 has been completely redesigned with a new front setup and a rear that features an AMG air suspension. The E63 also gets a variable suspension system with AMG Ride Control that allows for three different suspension settings: Comfort, Sport and Sport Plus.
Another adjustable feature is the stability control program, or ESP, which has three settings: “On,” “Sport” and “Off.” The Sport setting allows for increased slip.
For ease of use, the MCT transmission settings, ESP settings, suspension settings and AMG drive modes can all be adjusted via the AMG Drive Unit.
Other highlights of the E63 include 18-inch wheels that measure 18×9-inches up front and 18×9.5-inches in the rear with front 255/40/18 tires and 285/35/18 rear tires. The brake rotors measure a substantial 14.2-inches at each corner.
For those who demand even more from their car, AMG will offer a “Performance Package” that includes 19-inch wheels with 255/35/19 and 285/30/19 tires, as well as a stiffer suspension setup, a locking rear axle, a three-spoke performance steering wheel and a new top speed of 186 mph (standard top speed is 155 mph).
More on the E63 after the jump:
THE E63 AMG – A NEW-GENERATION SPORTS SEDAN DELIVERING TOP DRIVING DYNAMICS
Affalterbach, Germany – AMG is kicking-off the 2009 driving season with a new superstar: shortly after the launch of the new E-Class, the AMG high-performance brand of Mercedes-Benz Cars presents the new 2010 E63 AMG. This dynamic sports sedan impresses with outstanding performance, thrilling handling characteristics and advanced technology transferred from its sibling, the SL63 AMG high-performance Roadster. The E63 AMG makes its U.S. sales debut in November 2009.
The new E63 AMG distinguishes itself from the standard Mercedes-Benz E-Class sedans with a newly developed AMG RIDE CONTROL sports suspension with electronically controlled damping, revised front suspension and unique exterior and interior design. At the same time, Mercedes-AMG has achieved a significant reduction in fuel consumption of almost twelve percent for the new E63 AMG, thanks to the precise application of several fuel efficiency improvements. With its unique combination of pioneering driver assistance systems, the E63 AMG further consolidates the brand’s leading position in the field of automotive safety.
The AMG 6.2-liter V8-engine in the new E63 AMG develops an output of 518 hp and a 465 lb-ft of torque, matching the outstanding figures for the SL63 AMG. The high-performance Roadster has also transferred its AMG SPEEDSHIFT MCT 7-speed sports transmission to the new model. This transmission replaces the conventional torque converter through the use of a multi-disc wet start-up clutch. In conjunction with the four individual driving modes, rev-matched shifts and RACE START function, the resulting, direct connection to the powertrain delivers an extremely emotional and high-performance driving experience.
The AMG MCT drive unit is unique in this segment, and provides dramatic performance figures: the E63 AMG accelerates from standstill to 60 mph in just 4.4 seconds, with a top speed of 155 mph (electronically limited). The fast-revving, naturally aspirated engine with a displacement of 6208 cc impresses with its agile responsiveness, muscular power delivery and high redline. The AMG V8 sound is a thrilling partner for mile after mile, while the smooth-running engine guarantees renowned Mercedes long-distance comfort. A newly designed water cooling system ensures maximum endurance even under the enormous dynamic stresses of the racetrack.
Fuel consumption cut by almost twelve percent
Despite 11 hp of additional output versus the preceding model, the E63 AMG showcases several advancements designed to improve fuel efficiency, including on-demand delivery of fuel and alternator management with recuperation of engine power during overrun. In-engine friction is also reduced by the AMG-exclusive twin-wire arc spray coating process used to coat cylinder walls.
The AMG SPEEDSHIFT MCT 7-speed sports transmission also makes a decisive contribution to fuel economy: a multi-disc wet clutch running in an oil bath replaces the previous torque converter. This unit responds extremely rapidly, directly and without the losses typical of a torque converter transmission thanks to its low rotational inertia. The transmission is equipped with four driving modes: “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus) and “M” (Manual), which can be selected using a rotary electronic switch in the AMG DRIVE UNIT. Partial suppression of individual cylinders by interrupting ignition and injection during gearshifts under full load contributes to considerably faster shift times. In M mode the AMG SPEEDSHIFT MCT 7-speed sports transmission allows gearshifts to be performed in 100 milliseconds.
In the even more fuel-efficient driving mode Controlled Efficiency, the transmission shifts the gears with deliberate smoothness, and the transmission control unit is programmed to perform early upshifts to keep engine speeds as low as possible. At the same time, the AMG SPEEDSHIFT MCT 7-speed sports transmission met the most demanding requirements where driving dynamics are concerned: fast and precise multiple downshifts ensure first-class agility in conjunction with the automatic rev-matching and RACE START function: this enables the E63 AMG driver to call on the maximum acceleration potential automatically.
Electronically controlled damping system and a new front axle
Sporty or more comfort-oriented? The driver of the new Mercedes-Benz E63 AMG is not obliged to accept any compromises in this respect. The AMG RIDE CONTROL sports suspension copes equally well with the dynamic cornering of the racetrack and more comfortable, sedate driving. High performance and typical Mercedes long-distance comfort go together as an extraordinary synthesis in the E63 AMG. This is made possible by the newly developed AMG RIDE CONTROL sports suspension. While new steel spring struts are used on the front axle, the rear suspension features AMG-specific air springs. The advantage of this solution, which is exclusive to AMG, is that the front spring struts ensure more sensitive responses while the rear air struts with their automatic level control system keep the vehicle at a constant height, irrespective of the load.
A new, electronically controlled damping system automatically varies the damping characteristics according to the driving situation, reducing the roll angle of the body. The result is instant adjustment to provide the best possible ride comfort together with the greatest possible agility. In addition, the driver is able to choose between the three suspension modes of Comfort, Sport and Sport plus at the touch of a button. The E63 AMG is also equipped with a newly developed, unique front axle with a 2.2 inch (56 millimeter) wider track, a tubular stabilizer bar, new control arms, new wheel bearings, newly-designed bushing geometry and kinematics and new wheel location for more negative camber – thereby providing more grip when taking turns at speed. The AMG-specific kinematics also ensures significantly more precision. This is a highly sophisticated axle design whose principle has already proved its worth in the C63 AMG. The rear axle likewise has more negative camber, optimized elastokinematics and a new subframe mounting for greater stability at the physical limits.
Newly developed power steering and individual 3-stage ESP®
For more direct responsiveness, the speed-sensitive rack-and-pinion steering is also a new development. The steering ratio of 14 : 1 is 22 percent more direct (quicker) than in the standard production models, while a more rigid steering column plus the reconfigured characteristic mapping of the speed-sensitive servo assistance ensure better steering precision and improved road contact.
The 3-stage ESP® familiar from the SL63 AMG and C63 AMG enables individual settings to be selected – with clear benefits in terms of driving pleasure combined with the same high level of handling safety.
The ESP® key in the AMG DRIVE UNIT allows the driver to choose between “ESP ON”, “ESP SPORT” and “ESP OFF” – with the currently active mode shown in the central display of the AMG instrument cluster. Perfect deceleration even during performance driving is ensured by the AMG high-performance braking system with 14.2 inch, internally ventilated and perforated brake discs all-round. Particularly resistant, motorsports-tested compound (two-piece) construction technology is used at the front axle. Outstanding grip is ensured by the 18-inch AMG light-alloy wheels with a width of 9 and 9.5 inches and mixed tire sizes of 255/40 R 18 at the front and 285/35 R 18 at the rear.
Decidedly dynamic interior and exterior
The purposefully dynamic design of the E63 AMG is fully in keeping with the vehicle’s impressive technology. The front aspect is characterized by 17-millimeter wider fenders bearing “6.3 AMG” lettering, the new AMG front apron with large intake air apertures and the AMG-specific daytime driving lights in LED technology. In conjunction with the optional Bi-Xenon Headlamps with Active Curve Illumination, the E63 AMG is equipped with tinted main headlamps. The striking visual presence is further enhanced by the AMG side skirts and AMG rear apron with a black diffuser insert. As a hallmark of the brand, the AMG sports exhaust system has two newly designed, chrome-plated twin tailpipes.
The new interior of the E63 AMG is an exciting blend of high-grade materials and functional sportiness. Exclusive features include electrically adjustable AMG sports seats with improved lateral support and the AMG sports steering wheel in a four-spoke design with AMG shift paddles. As a completely new feature exclusive to the E63 AMG, the AMG selector lever has one-touch logic. Directly adjacent to it in the center console is the AMG DRIVE UNIT, which provides adjustments for the MCT sports transmission, the ESP functions, the suspension setup and the AMG driving modes. Standard equipment also includes high-grade leather upholstery in three different colors, the AMG instrument cluster with an AMG main menu, door entry sills with AMG lettering and a sports pedal cluster – both in brushed stainless steel.
