Ten years ago, Mercedes-Benz ushered in a new era of diesel engines in passenger cars, with "common rail direct injection" technology, first used in the Mercedes-Benz C-Class (202 series)

Common rail direct injection

This month signifies the ten year anniversary of the market launch of the Mercedes CDI, clean burning diesel technology. Before 1997 Mercedes did have turbodiesel cars in its line-up but the CDI common rail direct injection technology is fundamentally different.

First model in line was the Mercedes C 220 CDI, producing 125 hp (92 kW) with 300 Nm of torque available at only 1800 rpm! Making the engine the highest torque-engine in its displacement class while setting new standards in fuel economy.

2006 also marked an important milestone for the CDI when the Mercedes E 300 BLUETEC was voted “World Green Car of the Year”. The new Mercedes E 300 BlueTec for Europe already meets Euro V emissions standards, which won't come into force until September 2009.

Read on for more details on this break-through technology.
