Mercedes-Benz is now offering three new direct injected engines in its C-Class BlueEfficiency models. Two of the three four cylinder engines are diesels while the other is fueled by gasoline. The 2.2-liter diesel is available as a single turbo 170 hp version or a dual turbo 204 hp variant. The diesels produce 295 lb-ft and 369 lb-ft of torque respectively. The gasoline engine is a new 204 hp turbocharged 1.8-liter unit with 229 lb-ft of torque.

The gas engine gets a combined 32.7 mpg (U.S.) on the EU combined driving cycle. The diesels are the cars that really shine on the test cycle with the more powerful C250 CDI getting 42.1 mpg (U.S.) and the 170 hp C220 scoring 49 mpg (U.S.). Even with that kind of mileage, the C220 still runs to 62 mph in a very respectable 8.4 seconds. All three models are available as either sedan or station wagon.

Unfortunately, like BMW, Mercedes has decided not offer any four cylinder engines in the U.S. market in recent years. Hopefully Mercedes, will soon follow Audi's lead and switch from six to four cylinders.

Three newly developed engines with direct injection will make the Mercedes-Benz C-Class even more efficient. They 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 and therefore outstanding driving pleasure. The new C 220 CDI BlueEFFICIENCY saloon, the most efficient C-Class ever, generates 125 kW/170 hp and a torque of 400 Nm from a displacement of 2143 cubic centimetres. This accelerates the saloon from standstill to 100 km/h in 8.4 seconds, yet the combined fuel consumption is only 4.8 litres of diesel per 100 km (corresponding to CO2 emissions of 127 g/km) - the best figure in this category.
The newly developed four-cylinder in the C 250 CGI BlueEFFICIENCY also uses direct injection. It achieves 150 kW/204 hp and offers 310 newton metres of torque. The saloon requires 7.4 seconds for the sprint from 0 to 100 km/h with the new petrol engine. The combined consumption amounts to 7.2 litres per 100 km (CO2 emissions 168 g/km).

      I wonder who buys Mercedes diesels?

      5-year total ownership costs are for:
      - the ML 350 ordinary gasoline = $62,858
      - the ML 320 BlueTEC diesel: $64,344

      So everyone who wanted to save cash will be harshly disappointed.

      Mercedes diesels also harm climate and the Earth resources significantly more than ordinary gasoline SUVs, the one we call gas guzzlers. Below is a list of how many barrels of crude oil one needs (and how many tons of CO2 one emits) to cover 15.000 miles in selected vehicles.

      Lexus RX450H Hybrid...........11.8 barrels | 6.3 tons of CO2 | hybrid SUV
      Lexus RX 350 AWD..............17.1 barrels | 9.2 tons of CO2 | gasoline SUV
      Chevy Silverado Hybrid........17.1 barrels | 9.2 tons od CO2 | hybrid large pickup
      Cadillac Escalade Hybrid......17.1 barrels | 9.2 tons of CO2 | hybrid large SUV
      Toyota Highlander................18.0 barrels | 9.6 tons of CO2 | gasoline SUV
      Chevrolet Corvette...............18.0 barrels | 9.6 tons of CO2 | gasoline sportscar
      Hyundai Veracruz.................19.0 barrels |10.2 tons od CO2 | gasoline SUV
      Infiniti FX35...........................19.0 barrels |10.2 tons of CO2 | gasoline SUV
      BMW X5 xDrive 30i...............19.0 barrels |10.2 tons of CO2 | gasoline SUV
      Mercedes ML 320 Bluetec....19.7 barrels |10.6 tons of CO2 | DIESEL SUV

        I’m still trying to figure out what relevance downtoearth’s post has to this thread whatsoever. This topic is about the Mercedes C-class cars, not SUVs. In case you didn’t notice, downtoearth, the CO2 emissions are given in the OP – 134 g/km for the E250 CDI (diesel); 168 g/km for the E 250 CGI (petrol). That’s >25% better fuel efficiency on an energy-equivalent basis, and >20% LESS CO2 emissions. And this is with one of the supposedly super-efficient downsized turbo DI petrol engine in the E 250 CGI. Plus, the E 250 CDI outperforms the E 250 CGI 0-100 km/h (7.0 s for the CDI; 7.4 s for the CGI) according to the OP.

        As far as the “it takes more crude oil to make diesel than it does gasoline” assertion, that’s only because you get greater volumetric process gain from “cracking” heavier hydrocarbons in crude oil to gasoline than you do to middle distillate. However, it takes much more energy to accomplish that more severe cracking and concomitant higher CO2 emissions, nearly twice as much per unit volume (source: UC-Davis supporting documentation for their Lifecycle Emissions Model). So, you get lower direct CO2 emissions from the diesel vehicle plus lower CO2 emissions from processing the fuel. Sounds like the petrol vehicle is the more harmful to the earth’s climate and resources to me, in this case anyway.

        You might try looking again and using the numbers from the 2009 model...
