采用最新第四代高压共轨喷射系统的柴油机在入口端可产生高达29，000巴斯的高压，同时采用尿素喷射装置净化尾气。 梅塞德斯重新设计了4MATIC全轮驱动系统以减少摩擦，从而达到两轮驱动系统的效率。

草草看了看，参考下吧。。。。
【 在 dycqmjc (迷路的稻草人) 的大作中提到: 】
The diesel uses the latest fourth-gen common rail injection system that operates at 29,000 psi on the inlet side with Bluetec urea injection to clean up the exhaust. Mercedes has reworked the 4MATIC all wheel drive system to reduce the friction to the point where it's as efficient as a two wheel drive setup
