Mercedes-Benz said that the 2014 CLS 63 AMG and Shooting Brake will debut at the upcoming Detroit Motor Show. Mercedes will launch the updated E63 AMG as well as unveil the 2014 CLS 63 AMG which offers the same engine improvements as the top-of-the-range E-Class model. The V8 5.5-liter bi-turbo can deliver 557 HP (410 kW) at 5,500 rpm and 720 Nm (531 lb-ft) between 1,750 rpm and 5,250 rpm.
The four-door coupe can accelerate from zero to 62 mph (or from 0 to 100 km/h) in 4.2 seconds while the Shooting Brake can accomplish the same 0.1 seconds slower. Meanwhile, the 4MATIC versions can do so in 3.7 and 3.8 seconds, respectively. In addition, the updated CLS lineup will be available with the 4MATIC S-Model variant which raises its output to 585 HP (430 kW) at 5,500 rpm and 800 Nm (590 lb-ft) between 1,750 and 5,000 rpm.
The coupe will be enabled to get to 62mph in 3.6 seconds while the Shooting Brake can do so in 3.7 seconds. All the models are capable of reaching an electronically limited top speed of 155 mph (250 km/h). There are four modes offered with the seven-speed AMG SPEEDSHIFT transmission. These are: Controlled Efficiency (C), Sport (S), Sport Plus (S+) and Manual (M).
The S-Model is equipped with a rear-axle differential lock and features red painted callipers. The interior highlights include a black Nappa leather steering wheel, a revised AMG instrument cluster and grey contrasting stitching. It’s expected that the rear-wheel drive model will go on sale this April. The all-wheel drive version and the S-Model are slated to follow in June.
The AMG 4MATIC all-wheel drive from Mercedes-Benz demonstrates an excellent performance in that it is able to distribute the engine torque to the front and rear axle in the ratio of 33% to 67%. It also has a power distribution system that is rear-biased which is the AMG signature as it relates to unmatched driving enjoyment and high-level of driving dynamics.
In particular the all-wheel drive system has the 3-stage ESP which has been specifically tailored for it. When entering the “SPORT Handling” mode, the vehicle is able to avoid understeering especially when cornering or turning. This is made possible through the Torque Vectoring Brake which can execute braking intervention selectively on the individual wheels in order to achieve high agility.
When cornering for example, by applying the brakes on the inner wheel, the vehicle is able to achieve a more defined cornering. Aside from turning and cornering, the system also improves driving and increasing safety by enhancing the grip especially on wet surfaces or during winter when the road is covered in ice. The multi-disk clutch has a 50 Nm locking effect that makes use of the frictional connection potential of all of the vehicle’s four wheels whether on ice or snow thereby ensuring traction is optimized.
On a technical standpoint, what the system does is that it gives a transfer case to the driven rear axle in order to get additional take-off power. Since the transfer case has been integrated with the AMG SPEEDSHIFT MCT 7-speed sports transmission, there is no more need to have more installation space. During a power take-off, the torque generated is transmitted to the front axle through a propeller shaft.
What happens is that when the power is created, it is passed through an intermediate shaft which in turn also runs through a shaft duct that has been encapsulated and located in the engine oil pan before reaching the front-left drive shaft. Since the transfer case is not only compact but has also been optimized in terms of weight, the additional weight to the system is only around 70 kilograms. Another offering from Mercedes-Benz is the CLS63 AMG S-Model which is the AMG taken a level higher.
With the philosophy of “Driving Performance,” the rear axle of the CLS63 AMG has a differential lock fitted to it. As a result of this system, the CLS63 AMG experience increases traction, enhancing driving enjoyment and giving better driving dynamics especially on the race track. All the models of the CLS63 AMG come with the AMG RIDE CONTROL sports suspension with damping system that is electronically controlled.
While the front axle for example uses a steel-spring suspension system, the rear axle on the other hand has a fully load-bearing air suspension system instead. What happens is that when the button in the AMG DRIVE UNIT that is marked shock absorber is pressed, the electronics then switches to different modes from "Comfort" mode to "Sport" mode or even "Sport plus" mode. In addition, the three-link front suspension for the CLS63 AMG and the S-Model has been optimized further.
The optimization measures introduced, when combined with the aluminum axle components, result in the vehicle having better agility and grip plus a high level of neutrality which is particularly useful when cornering. S-Model also has the exclusive elastokinematics giving the driver not just better grip and feedback but it maximizes the neutrality which comes in useful during critical limits.
The CLS63 AMG meanwhile, whether the all-wheel drive variant or rear-wheel, has a front track that is wider by 24 millimeters. What this does is that it significantly provides better stability when cornering at higher speeds and enhanced road feel. Furthermore the negative camber on both axles have been increased thus boosting lateral dynamics even further.
