Looks like the end of all inline 6 motors from MB. Also the end of 5 cylinder diesel production.

If you dont want to click the link, here is the intro:

Agility and driving pleasure as standard
Mercedes-Benz is presenting a new V6 diesel engine which will replace the previous in-line five and six-cylinder engines from spring 2005. With an output of 165 kW/224 hp and a maximum torque of 510 Newton metres, the Mercedes six-cylinder is one of the most powerful units in its class. Thanks to the latest technology, the exhaust emissions meet the stringent EU4 limits; in addition Mercedes-Benz equips the V6 engine with a particulate filter as standard in Germany.


The concept of diesel driving pleasure achieves a new quality with the new CDI engine. As the successor to the five and six-cylinder in-line engines it offers an increase in output and torque of up to 38 percent, ensuring faster acceleration, brisk intermediate sprints and a higher top speed. The maximum torque of 510 Newton metres is already available from 1600 rpm, and remains constant up to 2800 rpm. Accordingly the new V6 has torque characteristics which are unsurpassed in this displacement class. In combination with the unique 7GTRONIC seven-speed automatic transmission, this ensures the best possible exploitation of the remarkable output and torque potential in any driving situation.


Despite a significantly higher output, the fuel consumption remains at the exemplary level of the previous five and six-cylinder diesel engines.


The choice of materials, design, fuel injection and engine management system reflect the state of the art. As a world first for a diesel engine in this displacement and output class, Mercedes-Benz has developed an aluminium crankcase with cast-in grey iron cylinder liners for this unit which makes a major contribution to weight reduction. As a result, the new V6 weighs a total of only approx. 208 kilograms (acc. to DIN) and is therefore only very slightly heavier than the previous five-cylinder engine. The power-to-weight ratio has increased by more than 20 percent to 0.79 kW/kg – a major contribution to the outstanding diesel agility offered by the new engine.


The engine block, components and ancillary units form a very compact entity, which means that in future the new V6 will also be installed in Mercedes model series and 4MATIC variants where no six-cylinder diesel engine was previously offered.

Thanks for posting the web site. It was a wonderful article

Bye-bye rebuildability.

Cool it is kind of sad to see the I6's die but the world marches on. I saw a new CDI idleing at the dealer today. Very quiet almost like a gas car and no hint of smoke, the new diesels are pretty cool.

V configuration on a diesel engine is a questionable approach. Witness the GM debacle 20 years ago. Too much torque for the block to hold up. Hopefully MB engineers have worked this out. To my knowledge big block mfrs (Cummins, Cat, Detroit, Mack have discarded the V and gone in-line. In the pickups only Ford has the V-8. Dodge/ Cummins and GM/Isuzu (duramax) are in-line. Oh well, ANY approach is superior to these hybrids coming out.

How's the track record been for the V8 S400 CDI Diesel in Europe? They've been out for a few years now.

I don't know about the diesel, but the S-Class was ranked 1st in the top 10 worst realiable cars from JD Power. The list was dominated almost exclusivly by BMW and Mercedes.
