What is the difference? om642 between EU / US ??

I am new to this forum and new to MB, acquired a 2007 R320 CDI 4matic NON-BlueTec from factory.

Anyone know what is the mechanical difference between the EU engine and the US engine?

What increases the hp and torque in the EU engine?

The copy below is from Wikipedia;

https://en.wikipedia.org/wiki/Merced...z_OM642_engine

I sniped{removed] the data on the "Mercedes/Dodge Sprinter" as the HP and torque is less.

Power output: european models: 195 kW (265 PS; 261 hp).
US vehicles: 157 kW (213 PS; 211 hp).
Torque output: european models: 620 N⋅m (457 lb⋅ft).
US vehicles: 540 N⋅m (398 lb⋅ft).

First, your CDI may not say BlueTec on the back, but don't be fooled... It has a DPF and will require 229.5x (or similar) oil in order to operate without total oil-related meltdowns.

Second, very few (if any) mechanical differences exist between the MY2007 Euro and US engines, and comparisons will certainly change depending on year/model/application. Most power differences when comparing an OM642 apples to apples are software derived due to emissions output limits between here and Europe (less fuel injected, more EGR, etc etc).

Also, that engine is still used in brand-new passenger car models in Europe, so there have been incremental updates and improvements over the years that have seen power outputs bump slightly.

Hope that explains some it for you.

This guy is wrong and you're misunderstanding the wiki reference. The 265 model has a completely revised head and newer water cooled turbo. That same engine was sold in the US in 2012-2013 in the S350 Bluetec and was also sold in the final years of the OM642 powered GL and ML. It was rated at 240HP in the US, but that was likely BS because it had the exact same 457 ft/lbs rating that the EU spec model had and if you put one on the dyno it shows closer to 240HP at the wheels.

The earlier OM642s are what is cited as the US model in OPs link.

"265 model" is ?

Would you know what engine code would be for the om642 with the revised heads and newer water cooled turbo?

I researched OM642.872 engine code is (3.0 V6, 195 kW (265 PS; 261 hp)]

265 was referencing the one you mentioned showed as having 265PS that you found on Wiki. I'm not positive of the designation for that specific one, but if you look up a 2015 W212 EU model, it should have it. The US 2013 S350 Bluetec is likely designated differently but dynos the same. Good luck trying to convert yours to that version, you'll need the ECU to go along with it, which means you'll need all of the other associated electronics due to how heavily everything is integrated. The closest you're going to get in the US is to buy a S350 or ML350 bluetec in their final years. They didn't even put that same engine in the US spec 2013 W212 bluetec.

Actually, the German wiki identifies it as "OM 642 LS EN 30 LA *" https://de.wikipedia.org/wiki/Mercedes-Benz_OM_642 , but there were several versions with the same designation and different HP, likely owing to ECU or exhaust differences over the years
