Mercedes-Benz announced a new range of four-cylinder diesel engines today, reiterating their focus on reducing engine size while maintaining performance. The new lineup delivers better economy and power levels than Mercedes? previous generation of four-cylinder diesel engines, with the most powerful variant delivering 20% more power and torque than the outgoing powerplant.
The range topper is a new 204hp 2.1L unit with a peak torque of 500Nm ? as much twist-force as a petrol V8. Despite the increase in power and torque, the new four-cylinder diesel burns substantially less fuel than its predecessor and as a consequence CO2 emissions are reduced by as much as 13% and are now in line with future EU5 emissions standard.
The extra performance comes from several tweaks to the injection and common-rail system, now in its fourth generation, as well as an increase in fuel pressure, higher turbo boost from new twin-stage turbochargers, more efficient intercoolers and exhaust recirculation and improved fuel and water pumps.
The new engine lineup will initially be offered in the C-Class sedan. It will come in three guises: 250CDI with 204hp, 220 CDI with 170hp and the 200CDI with 136hp. There are also plans to put the engine into SUV?s, as well as install it in hybrids and possibly combine it with Mercedes? BLUETEC technology. The top of the line 250CDI will accelerate from 0-60mph in about 7.7 seconds and still return fuel economy of 46mpg.

Yay, just in time for $5/gallon diesel!
Seriously, though, good for them. Is that imperial or US gallon? Because IIRC, the UK/Euro 'gallon' is 1.2x ours. That would mean ~38mpg US? IDK, could be wrong.

They usually don't use mpg but liters per 100km so it's probably American gallons.

Don't forget England has much easier testing, there the Prius gets 65.7 combined mpg while here it gets 46combined.
If we do the math, 65.7*.83(for imperial to us gallon conversion)=54.531
That's the same as the old EPA estimates(55mpg combined). For gasoline cars and diesels, the average drop is ~10%, for hybrids, more. For the E320Bluetec, it was 30->26 which is just over 15%.
So if we revise it,
46*.83 = 38.18
38.18/1.15384615=33.089
Now taking data from the government on average gas and diesel prices 2 weeks ago,
Diesel is $3.998 average nationwide while Gas is $3.259
33.089/1.22675667=26.97mpg (efficiency as compared to gasoline)
That's good but no longer "OMFG OH Shit" good.
That's why I hate these "look at these amazing euro diesel" articles. It creates false expectations through fudging the numbers. Realistically, you get comparatively for the price 4mpg better.

It's exactly where one would expect a car with these horses to go. People splurge all over their keyboard at torque figures but torque doesn't get you a fast car at the lights. It feels peppy until you floor it and realize that, damnit, you are changing gears at 4k rpm. The true power of a car is its HP, torque is just a manifestation of the engine and gearing. If one looked at torque, they'd probably think a TDI Jetta would take an S2000 at the lights.Originally posted by: RichieZ

lol yeah. 7.7 is the 0-60 time of the Vette during the 80s. It's not screaming, but it's far better than many vehicles that do it in 8, 9, 10, or even 11+ seconds.
For a 4-cylinder Diesel Sedan, it's damned impressive actually.
