Mercedes-Benz is set to unveil the refreshed 2014 E-Class at the Detroit Auto Show this January, and with it comes the highly anticipated new E63 AMG, available in both sedan and wagon variants. Enthusiasts have long admired these high-performance machines, and recent trends in the performance sedan market have only heightened anticipation for this release. The rise of all-wheel-drive (AWD) in high-horsepower sedans has become increasingly noticeable, particularly after experiencing the impressive Audi S8 with its dyno-proven 575 horsepower and the traction advantage demonstrated by the AWD Porsche Panamera GTS against the rear-wheel-drive (RWD) BMW M5. It’s clear that AWD offers a significant performance edge in heavier, powerful sedans. This realization hasn’t escaped AMG, as CEO Ola Kaellenius himself offered a preview of the groundbreaking new 2014 Mercedes-Benz E63 AMG 4Matic – the first non-SUV AMG vehicle to feature AWD. This writer was fortunate enough to experience a day as a passenger in this exciting new machine.
AMG Re-Engineers 4Matic for Performance
“We didn’t simply adapt Mercedes’ existing all-wheel-drive system. That wouldn’t be suitable for AMG,” Ola Kaellenius stated, emphasizing AMG’s commitment to performance. Tobias Moers, head of AMG Vehicle Development, further elaborated, “We completely re-engineered 4Matic to meet our specific demands.” The key difference lies in the torque distribution. While standard Mercedes 4Matic systems typically use a variable torque split ranging from 45/55 front/rear to adjust for changing conditions, the 2014 Mercedes-Benz E63 AMG 4Matic boasts a fixed 33/67 front-to-rear torque split. This permanent rear-biased setup is crucial for maintaining the signature AMG driving dynamics and performance feel.
This fixed torque split is driven by AMG’s core performance focus. Furthermore, by streamlining the system – removing electronically locking clutches and reducing rear half-shaft size – AMG managed to minimize the weight penalty. According to AMG, the AWD system adds only 44 pounds to the E63’s weight. If these figures are accurate, the AWD E63 could weigh in at around 4391 pounds, comparable to the RWD BMW M5’s 4406 pounds. While AMG remained tight-lipped about future models, the introduction of AWD in the E63 AMG strongly suggests that AWD may also be on the horizon for the next S63 and S65 models.
A Sneak Peek in Camouflage
An exclusive ride-along experience was granted in two of the three pre-production 2014 Mercedes-Benz E63 AMG 4Matic mules. These prototypes, initially identically camouflaged, were being put through their paces at the former Marine base El Toro. One mule, intended for autocross testing, had its front fascia camouflage partially removed by Tobias Moers to ensure adequate radiator and intercooler airflow. This unintentional reveal offered a glimpse of AMG’s new, sportier corporate front-end design, highlighted by a curved front splitter dubbed the “A-Wing.” While taped over in black on the mules, speculation suggests it will be chromed in the production version. The A-Wing is a key element of AMG’s evolving design language, set to be fully showcased with the next-generation C-Class launch.
The journey to the test track began at the luxurious Montage Hotel in Laguna Beach in the less disguised silver E63 mule. Even the interior was camouflaged, but Tobias quickly removed a shroud covering the navigation screen, revealing an updated COMAND system with sharper graphics and a modern gray background, replacing the previous beige. While a detailed interior inspection was limited, the steering wheel was noticeably more “sportive,” and the metal vents added a touch of refinement.
Launch Control and Blistering Acceleration
Upon reaching a secluded runway staging area, Tobias demonstrated the 2014 Mercedes-Benz E63 AMG 4Matic’s launch control system. Engaging “Race Launch” mode, similar to the SLS Gullwing, and utilizing the AWD traction, the car unleashed phenomenal acceleration. The previous RWD 2012 E63 AMG already achieved a remarkable 0-60 mph time of 3.8 seconds. Tobias confidently stated the new AWD model would hit 60 mph in just 3.4 seconds, or 3.5 seconds to 100 km/h, claiming they “removed a tenth.” If these figures hold true, the 2014 Mercedes-Benz E63 AMG 4Matic would become the quickest four-door vehicle globally, surpassing even the Porsche Panamera Turbo S and Audi S8. While the test runs were conducted on a damp and imperfect runway, the sheer acceleration was palpable, hinting at sub-12-second quarter-mile potential. Official testing of a production model will be needed to confirm these impressive claims, but the initial experience with AWD and launch control is undeniably sensational.
Enhanced Power and AMG Engineering
The 2014 Mercedes-Benz E63 AMG 4Matic also benefits from a significant power upgrade. The previous E63 offered a 5.5-liter twin-turbo V-8 with 518 hp (or 550 hp with the Performance Package). The new model consolidates this approach, with the M157 engine now producing a robust 575 horsepower and an undisclosed, but likely substantial, increase in torque. The familiar seven-speed, wet-clutch planetary transmission remains, and U.S.-spec models will include a rear limited-slip differential. While suspension changes were described as minor adjustments to accommodate the AWD components, the front wheels now feature 1.9 degrees of camber. Optional carbon-ceramic brakes were present on the silver mule, along with new Pirelli tires (255/35R19 front, 285/30R19 rear). The demanding test track conditions at El Toro proved challenging for the tires, suggesting potential changes for the production vehicle.
Despite the AWD system, the 2014 Mercedes-Benz E63 AMG 4Matic retains a playful character. During cornering, the rear-biased torque split allows for noticeable tail-happiness, requiring counter-steering and throttle input to engage the front wheels and maintain control – a testament to the system’s performance-oriented design. While a definitive assessment of handling agility from the passenger seat is limited, the car felt undeniably aggressive and nimble. Tobias Moers’ driving skill further highlighted the vehicle’s dynamic capabilities, reinforcing the link between AMG’s engineering expertise and on-track performance, as exemplified by the C63 Black Series.
Leading the Performance Sedan Segment
The 2014 Mercedes-Benz E63 AMG 4Matic arrives at a time when the performance sedan segment is ripe for a new leader. With the BMW M5 evolving towards a more grand-touring character, the segment crown is up for grabs. Competitors like the Porsche Panamera, Cadillac CTS-V, Tesla Model S, Jaguar XFR-S, and the upcoming Audi RS7 all present formidable challenges. However, the combination of AWD, increased power, and AMG’s performance engineering positions the 2014 Mercedes-Benz E63 AMG 4Matic as a strong contender for segment dominance. The upcoming comparison tests between these titans of performance sedans will be highly anticipated, promising a thrilling showdown for horsepower supremacy.
