20% more power, 25% more torque, EU5 emissions compliant and a 13% improvement in FE makes for one heck of a combination. Only in Europe again :( (http://www.cleanmpg.com/forums/showthread.php?p=85255)

MB C-Class with upcoming all-new 2.1L European Super Diesel.
Mercedes-Benz design engineers have achieved the impossible with their new four-cylinder diesel. The most powerful variant extracts 204 hp and 369 Lb-ft. from a displacement of just 2.1L.
Even Lower fuel consumption despite greater output
This fuel consumption figures for the C-Class, in which the diesel ICE will be making its debut consumes just 43.5 mpgUS on the NEDC (New European Driving Cycle). The 170 HP variant returns an even lower fuel consumption 46 mpgUS on the same. We are talking COMBINED!
Besides reduced CO2 output due to increases fuel economy, the design has succeeded in reducing untreated engine emissions. Even without an active denoxification process (Urea injection into an SCR is not part of this engines emissions package), the new four-cylinder diesel exceeds the upcoming EU5 emissions standard.
Real world performance
The C-Class equipped with the upcoming 2.1L diesel achieves near sport car performance, w/ a 0 – 60 time in under 7.7 seconds and just 9.4 seconds to pick up from 37 to 75 mph.
C-Class 2.1L Diesel options at a glance
Model|250 CDI|220 CDI|200 CDI
Cylinders|4|4|4
Valves/Cylinder|4|4|4
Displacement (cc)|2,143|2,143|2,143
Compressions Ratio|16.2:1|16.2:1|16.2:1
Max Output (HP)|204|170|136
Max Torque (Lb-Ft.)|369|295|243
Latest technologies to achieve fuel economy and performance targets
The new engine’s power and torque output, fuel economy plus lowered exhaust emissions are the result of a the inclusion of a number of new technologies which cannot currently be found in any other standard-production passenger car diesel engine.
Two-stage turbo-charging ensures high power output and optimum torque delivery.
Fourth-generation common-rail technology with a rail pressure of 29,400 psi, plus a new piezoelectric injector concept featuring direct injector needle control.
The maximum ignition pressure is 2900 psi contributing to the high output.
Both the oil-spray nozzles and the water pump are electrically driven and activated in accordance with requirements to save energy.
The camshaft drive is positioned at the rear in order to enhance running refinement and satisfy the exacting pedestrian protection requirements.
Two water jackets guarantee maximum cooling.
The forged crankshaft with its eight counterweights are supported by five bearings for vibration control.
To compensate for the free vibration moments which are inherent to all I4 engines, there are two Lanchester balancer shafts at the bottom of the engine block running in low-friction roller bearings.
A two-mass flywheel, featuring a primary flywheel mass fixed to the crankshaft that is connected to the secondary flywheel mass on the transmission by means of springs, isolates the crankshaft's vibration from the drivetrain, thereby contributing to the engine's excellent smoothness.
