When you look at the picture of the 2015 Mercedes-Benz ML250 it will appear almost similar to the ML350 of 2014, which it is going to replace. This is because it is the same vehicle. The car was completely refreshed for the 2013 model year and for the next year the ML will get updated for its styling.


This is attributed to the GLE class adaptation but for the present the ML diesel will get some minor changes for the exterior.   Under the hood it also welcomes the 2.1 Liter dual turbo diesel engine of Benz.   This is also the same Powerplant that powers the Mercedes E250 Sedan and the GLK 250 with unexpected amount of punch and improvement and this unit is going to be the first four cylinder diesel to enter the US in decades.

When we are reviewing a car then comparisons are inevitable  so let is  finish it off: the ML250 with its 200 horses and the 369 lb-ft torque is not anywhere near the power department to the departing ML35 with V6 turbo diesel generating 240hp and 455 lb-ft  thrust. But there are benefits of losing 2 cylinders though, as it reduces weight. The ML 250 still weighs a huge 5041 lbs on our scales but  it still manages to shave off 162 lbs from the 2013 ML350  Blue Tec 4MATIC’s 5203 pound weight.

  However the weight reduction was not effective in balancing the loss of muscle power. With the short sprint timing of 8.3 seconds and the quarter mile’s 16.3 seconds the 250 has given away a second in both the 0-60mph’s 7.0 seconds and 15.4 seconds timing in the quarter. Off the line acceleration of the four-cylinder is very torquey the turbochargers in sequence attempt their best to offer low-end boost to alleviate lag. A smaller turbo does this while a larger unit helps build boost at higher speeds. The turbochargers keep working to maintain momentum while the seven-speed automatic transmission invisibly changes through gears. One can safely assume that the urban customer buying the ML250 will not miss the V-6’s services. 

With the EPA rating of 22/29mpg   for city /highway the ML250 competes with a horde of rivals in the ball park in the lineup of Jeep Gran d Cherokee EcoDiesel 4x4, BMW X5 xDrive35d diesel and the VW Touareg TDI.  We observed 24mpg when the ML250 was in our hands, which is also similar number offered by the ML350 with V-6. We were hoping that some improvement in the form of efficiency will be seen given the loss of 162 pounds and two cylinders.

The numbers are conspicuously not communicating the amicable and willing nature of the 2.1 Liter diesel engine.  It is quiet and smooth for a diesel, and the refined quality makes the four-cylinder unit with compression ignition figured in the BMW 328d xDrive Sports Wagon coarser. Base price of this five-door hatchback with five passenger capacity is $50, 725 and the tested vehicle carried a price tag of $68,610.
