Benz reveals more fuel efficient C-Class
June 8, 2009 by David Twomey
Mercedes-Benz has revealed three new fuel efficient engines for its C-Class sedan and Estate, although as they are BlueEFFICIENCY engines its not clear when we will see them in Australia.
Mercedes-Benz says the engines raise performance and driving enjoyment to a new level, while demonstrating exemplary economy and environmental compatibility.
The new engines impress with a low fuel consumption, and therefore exemplary environmental compatibility, while delivering a high output for outstanding driving pleasure.
The new C220 CDI BlueEFFICIENCY sedan, the most efficient C-Class ever, generates 125kW and 400Nm from a displacement of 2143 cubic centimetres.
This accelerates the saloon from standstill to 100km/h in 8.4 seconds, yet the combined fuel consumption is only 4.8 litres of diesel per 100 kilometres, coupled with a CO2 emission of 127g/km – the best figure in this category.
The C250 CDI, with the same displacement, produces 150kW and 500Nm with a fuel consumption of 5.1L/100km, coupled with a CO2 figure of 134g/km and a 0-100km/h figure of 7.0secs.
The newly developed four-cylinder in the C 250 CGI BlueEFFICIENCY also uses direct injection.
It achieves 150kW and offers 310Nm, while needing 7.4 seconds for the sprint from zero to 100km/h with the new petrol engine.
The combined consumption amounts to 7.2L/100km, and CO2 emissions are 168g/km.
The new model variants of the Mercedes-Benz C-Class are available as both sedan and estate models in overseas markets.
Print it: 
Are these variants equipped with the 7G-TRONIC gearbox? Because ages ago when MB was spruiking the development of their new 4-cyl engines, they stated that they could be mated to their (at the time, just as new) 7 speed gearbox.
But within the E-class application, these engines are mated to their older 5G-TRONIC gearbox (as a cost saving measure, I bet).
Either way, pretty impressive stuff.
BMW’s 320D sedan does 0-100 in 8 secs (130kW/350Nm) and the 330D sedan does 0-100 in 6.2secs (180kW/520Nm). The fuel consumption figures aren’t as good though — 5.4L/100km and 6.8L/100km respectively. Being Bimmers they probably handle better too. I’ll admit I’m a bit biased against the C-class — the finish is too “cheap plastic” for my liking (especially for amount of $$$ you put down).
im with you G, although this is impressive, the Bimmers would probably rate better. I really despise the C-Class interior and like the flowing nature of the 3 series bettre. But good For Merceds Benz anyway.
I’ve owned a couple of mercs and I concur with G and Shak, the inside of the C-Class is cheap looking. I don’t mind the exterior styling of the car but the interior is disappointing.
I was looking at buying one when they were released so I’ve driven ever variant of the C-Class and the diesels, the 220 and 320, are dangerous. From the time when you hit the accelerator to when the car actually starts to move there is a good second delay. Now a second doesn’t sound like much but if you are trying to get out or the way of an oncoming car then it is a hell of a long time.
Considering how safety conscience Mercedes are I can’t believe they would produce a car with such a serious flaw. I own a ML diesel and it doesn’t have the delay of the C-Class so I don’t understand how they can get it so wrong.
And the diesel does it again. Petrol following where diesel leads.
That red Estate pictured is a Pre-July-2008 produced model with yucky mirrors =|
Oneill3 – Would that be from standstill or rolling?
I had an unusual experience today in my C63 where I ended up in a terminating lane and needed to get going, rather quick. So as you do, you slow down and wait for a gap in traffic – however, not stopping completely. Now when it came to putting the foot to the floor, I could’ve sworn there was a delay before anything happened although I bring this down to the car possibly making it’s way from the 3rd to 1st cog hence why I ask if the two diesels you tested were rolling or not at the time (keeping in mind that apart from this, the 63 has been sharp as a tack =D)
Camski
I have had this happen too in both my SLK 350 & C63. When you are just cruising along it has to ‘think’ when you ask the car to boot it when in C, never a problem in M or S. I suppose this could be fixed with a DSG.
Disappointing interior from MB. I once sat in a B class and was immediately reminded of Malaysian/Korean car trims. In fact in some of the Korean cars, I dare say the trim is better. I sat in a C class lately and noted the trim is not in line with an upmarket car. MB make great cars and they should do better.
