CARBARN | Mercedes-Benz E63 AMG Wagon (2012) | The new E63 AMG sedan and wagon are equipped with a 5.5-liter version of the new Mercedes-Benz V8 biturbo that produces more power while providing better fuel economy. Replacing normally aspirated AMG 6.3-liter V8, the characteristics of the smaller twin turbo engine, direct fuel injection and multi-spark ignition. Compared with the AMG previous displacement is reduced more than offset by the increased power of its turbo twin - one for each bank of cylinders. All three new engines make use of leading technology electronics industry first used in Mercedes-Benz diesel - electronic fuel injectors that spray fuel directly into the combustion chambers rather than indirect injection fuel door on most petrol engines used in the past.
The E350 and E550 2012 models feature a 7-speed automatic transmission with a new torque converter clutch lock-up more advanced offering fuel consumption, better yet, driving faster, quieter operation and greater durability. Low pressure hydraulic and electronic advanced software helps provide even smoother shift. When PRE-SAFE Brake senses an impending collision, the system emits three warning signs. About 1.6 seconds before impact is likely, partial braking is initiated automatically, and the PRE-SAFE occupant protection are enabled.
All E-Class models are equipped with standard PRE-SAFE System - the world's first that can detect and take protective measures before a crash. The innovative PRE-SAFE system first tensions the seatbelts automatically if the car senses an impending collision. PRE-SAFE uses resettable electric tensioners in addition to the existing pyrotechnic pretensioners. Moreover, if the front passenger seat is too reclined or forward, PRE-SAFE automatically moves to a position more favorable accident.
If the vehicle skids (often a precursor to rollover), the system closes the sunroof and side windows. If necessary, the pre-SAFE reacts fishtailing (or oversteer) and "plowing" (or understeer) by means of existing sensors for stability control ESC to measure the steering angle, yaw rate and lateral acceleration of the vehicle. Emergency braking can also trigger PRE-SAFE, which monitors the sensors for the Brake Assist as well.
