http://www.youtube.com/watch?v=Jm90__azVSo Mercedes has revealed the 2014 S 63 AMG ahead of its public debut in September's Frankfurt Motor Show. The high performance Mercedes flagship sedan is powered by a direct-injected, twin-turbocharged 5.5-litres V8 engine which delivers 585 bhp and 900Nm of torque. The engine is mated to a seven-speed AMG SPEEDSHIFT MCT sports transmission with three selections, namely "C" (Controlled Efficiency), "S" (Sport) and "M" (Manual). Both the SWB and LWB S 63 AMG take only 4.4 seconds to reach 100km/h from standstill. The AWD 4MATIC model even manages to shave off 0.4 seconds from the century sprint performance. All models have an electronically limited top speed of 250km/h. The new S 63 AMG is up to 100kg lighter than its predecessor due to several weight saving measures. These include the usage of light alloy rims, aluminum construction for the roof and front panels, usage of carbon fibre for the spare wheel recess, among others. The lithium-ion battery itself already contributed to 20kg of weight savings. The S 63 AMG is equipped with Mercedes' AIRMATIC suspension which offers continuous damping adjustment. This enables the performance sedan to adjust better to driving styles and road conditions. The suspension offers two settings, namely "Comfort" and "Sport". A torque vectoring system helps to improve handling. High performance AMG ceramic composite brake, which weighs 20 percent lighter than stock ones, is on the option list.

After much anticipation and speculation, the 2014 Mercedes E 63 AMG has finally show its face in an official photo alongside with its lesser brethrens that include the sedan, wagon, coupe and convertible variants. The hottest version of the E-Class range is expected to be powered by the existing 5.5-litre V8 twin-turbo which is good for 518bhp and 699Nm of torque. A performance package is available which pumps up the engine to 550bhp and 799Nm of torque. The E 63 AMG will be presented at the upcoming Detroit Motor Show. A statement from Mercedes reads, "Not only will we introduce the E-Class Saloon, Estate, Coupe and Cabriolet, but also the E 63 AMG model, now available in a 4MATIC version and, of course, the new four-door coupe, the CLA." 4Matic is the name of an AWD four-wheel drive system developed and used by Mercedes-Benz. Like the regular E-Class saloon, the E 63 AMG has a re-designed single headlamp unit. However, it sports a more aggressive front bumper that houses huge air intakes on both sides.

Most of Mercedes-Benz's cars come with their 4Matic all wheel drive system except for their compact models, the A-Class and the B-Class, which are front wheel driven. But in the near future, one of their upcoming compact models, the CLA Class sedan will feature a new version of the 4Matic system which is specially designed for cars with transversely mounted engines. The upcoming CLA Class is based on the same platform that the A-Class and B-Class is on but it will be featured with an all wheel drive system which Mercedes-Benz has never done before on their compact models. Therefore, a new system has to be developed for it. This new system integrates the rear axle driveshaft with the transmission and in this case, a seven speed dual clutch gearbox. Another feature of the system is an electro-hydraulic controlled multi disc clutch at the rear which allows full variable distribution of the drive torque between the front and rear axles. Normally, when the multi disc clutch is open, the car is driven by the front axle. When it is closed, the rear axle comes into action. The drive torque can be distributed between the front and rear axles according to the situation. The company's 4Matic system based on rear wheel drive is different. There is a 45:55 torque split between the front and rear axles during normal driving conditions and seventy percent of that torque can be directed to either axle when required. The torque variability of the new system allows for different driving modes which can be operated through a button on the dashboard. There are three modes; Eco, Sports and Manual. In Eco mode, less torque is directed to the rear which results in better handling and lower revs. In Sport and Manual, more torque is distributed to the rear axle. On the AMG versions, more torque is distributed to the rear axle to give the car a more rear-biased feel. The system is also linked to AMG's three stage electronically stability control system. The CLA Class is said to debut in early 2013 and will go on sale in the middle of next year as a 2014 model.
