Mercedes adds efficient four cylinders to E-Class, 45 mpg (U.S.) diesel
In Europe, at least, Mercedes-Benz is adding a pair of E200 BlueEfficiency models to its brand new E-Class lineup for 2010. Both variants use four cylinder engines with turbocharging and direct injection, although they burn different fuels. The E200 CGI uses gasoline to get 184 hp and 200 lb-ft of torque from its 1.8-liter engine. That's enough to move the sizeable E-Class to 62 mph in just 8.5 seconds while averaging 32.7 mpg (U.S.) on the EU combined driving cycle.
If, on the other hand, you really want to maximize efficiency, the diesel-powered E200 CDI is the way to go. Using the 136 hp variant of Mercedes' new 2.1-liter four cylinder diesel with a single turbocharger, it averages 45.2 mpg (U.S.) on that same driving cycle. With 365 lb-ft of torque it still gets to 62 mph in a reasonable 10.2 seconds. Both engines meet EURO V emissions, but neither is likely to appear on U.S. shores anytime soon.

Mercedes-Benz E-Class: New, efficient four-cylinder models ready to roll
Stuttgart,
Jul 17, 2009
Stuttgart - Mercedes-Benz is adding to the engine line-up for the new E-Class by introducing two economical four-cylinder models. The E 200 CDI
BlueEFFICIENCY developing 100 kW/136 hp consumes 5.2 litres of diesel per 100 kilometres, while the new E 200 CGI BlueEFFICIENCY has an output of 135 kW/184 hp and consumes 7.2 litres of petrol per 100 kilometres.
BlueEFFICIENCY developing 100 kW/136 hp consumes 5.2 litres of diesel per 100 kilometres, while the new E 200 CGI BlueEFFICIENCY has an output of 135 kW/184 hp and consumes 7.2 litres of petrol per 100 kilometres.
Sophisticated, efficient four-cylinder engines make for lower fuel consumption and less environmental pollution without having to compromise on classic Mercedes attributes such as ride comfort and driving enjoyment. As shown by two new E-Class models, which Mercedes-Benz is introducing to complete its engine line-up in the executive category.
The diesel powerplant in the E 200 CDI BlueEFFICIENCY has a displacement of
2143 cc, an output of 100 kW/136 hp, and consumes 5.2 to 5.5 litres of diesel per 100 kilometres (CO2 emissions: 137 - 145 g/km), enabling the Saloon to accelerate from zero to 100 km/h in 10.2 seconds and reach a top speed of 210 km/h.

The petrol engine in the new E 200 CGI BlueEFFICIENCY boasts a displacement of 1.8 litres and an output of 135 kW/184 hp. It takes 8.5 seconds to accelerate from zero to 100 km/h and has a top speed of 232 km/h. This model consumes 7.2 litres of premium unleaded petrol (RON 95) per 100 kilometres (CO2 emissions: 169 g/km), not least thanks to the ECO start/stop function, which is fitted as standard in conjunction with the six-speed manual transmission.
These are all-new four-cylinder powerplants with direct injection. One of the main features of the new diesel engine is latest-generation common-rail direct injection. The likewise new four-cylinder petrol engine with direct injection is fitted with a turbocharger as well as adjustable intake and exhaust camshafts.

Nothing to miss - the American market offers by a mile more efficient, simpler, more reliable and cleaner technology.
The previous generation Mercedes E200 CDI 136HP diesel does combined real life 7,38 l/100km = 31,8 mpg US. [1] Expect similar readings here. This amounts to, by proportion, 10.8 barrels of crude oil to drive 15k miles [2].
This is poor. Ford Fusion hybrid needs 8.8 barrels [3] or even less (it exceeds EPA estimate [3]) to do the same job, being 22,7% or even more efficient. Toyota Camry hybrid will need 10.1 barrels and the Lexus HS250h 9.8 barrels. Both cars exceed EPA estimates as well, likely burning even less.
Fusion, Camry and HS250h hybrids also offer significantly better performance:
- E200 CDI 0-60 in ~10 seconds
- Camry and Fusion hybrids in ~8.6 seconds, 14% quicker
Those hybrids also have very similar dimensions as the E-class:
- E200CDI = 485 cm of length
- Fusion Hybrid = 484 cm
- Camry Hybrid = 480 cm
The only drawback are some 10 cm less of wheelbase.
To sum up - cars offered in the USA shoot down this Mercedes diesel by being even 22% more efficient while offering 14% more performance and maintaining body size. Hybrids will also be by a mile cheaper to buy, service and maintain (no complex injection systems, turbos, exhaust treatment, automatic gearboxes).
No wonder Germans don't offer it here. They know their product is inferior and selling it is feasible in Europe only.

Its quite convenient in all your comparisons that you always assume hybrids do better than their EPA estimates and diesels do worse. Eventhough EPA itself admits hybrids generally underachieve their EPA estimates while diesels consistantly overachieve them. Also you always claim diesels are more expensive to maintain with "complex injection systems, turbos, exhaust treatment, automatic gearboxes" but fail to mention the complex electronics, engine controls, and batteries that hybrids have. Also failing to mention that those hybrid sedans loose half of their trunk for battery storage, a big issue to many people.

Comparing apples to apples, gasoline-electric hybrid systems are NOT cheaper to buy.
The upfront cost of a full hybrid system is more than 2x that of choosing a turbodiesel instead for even a small hybrid system like that in the Prius.
Given the time value of money, it is very difficult to recoup the initial difference.
why not the LS2LS7? 12:08PM (7/20/2009)
That's not true Brandon. He assumes this vehicle will get a 31.7 combined on US EPA measure based upon its European-cycle 32.7 (US gallons) combined figure. This is incredibly optimistic. For example the VW Jetta 2.0 TDI (170HP) is rated at 39.9 (US gallons) mpg combined on the European cycle (29.8/49.0 city/hwy in US gallons) and only 34mpg (US gallons) combined on the EPA cycle (30/41 city/hwy in US gallons).
Every vehicle's rating is significantly lower on the EPA cycle than on the optimistic European cycle, and downtoearth is assuming this vehicle will almost equal its EU rating in actual use, thus greatly exceeding the US EPA figures. And yet the Fusion still tops it significantly on fuel economy.

Hey, "why not the LS2LS7?", I always try to pick the real life fuel consumption as a basis of energy efficiency comparison.
That's why I usually scan Spritmonitor and EPA shared mpg sites. Then I convert the readings it to mpg US, and then, by a proportion, estimate the volume of crude oil needed to produce the fuel. And then compare.
For instance, EPA says 140HP Jetta TDI does 34 mpg combined which sources to 11.6 barrels of crude. Large sample on Spritmonitor says it does 38 mpg, the EPA shared mpg will tel you about 40 mpg. So I assume some 39 mpg of real life fuel economy and then adjust the amount of crude oil by proportion
11.6 barrels of crude / (39 mpg real life / 34 EPA mpg) = ...
From what I observed:
- gasoline cars do exactly what EPA says or a tiny bit better
- diesel cars often exceed EPA rating by some 4 mpg
- hybrid cars often exceed EPA rating by some 2 mpg
- diesel SUVs do more or less what EPA says

Mercedes E class is not comparable to a Ford Fusion or Toyota Camry. Only similarities is that they have 4 doors 4 wheels and are almost the same length. Only comparable Ford would maybe be a Lincoln MKZ or Lexus ES. If you compare the Mercedes to those it beats the pants off them.
When Peterbuilt talks about the fuel consumption of its over-the-road trucks do you also do a cost comparison to how that it is inferior to the Prius? Your handpicking of information and apples to oranges comparisons to back your opinion that diesels are worthless and hybrids are great is getting very tiresome.

Give it up Brandon. Downtoearth is the Osama bin Laden of diesel bashing. He burns with the passion of a thousand suns to see oil burners brought low. He scrubs himself for hours after every time he rides a diesel bus. He once rent his sleeves at the sight of a 79 diesel Rabbit. Diesel is unclean! Jihad Jihad!
why not the LS2LS7? 12:13PM (7/20/2009)
I agree, the Fusion is not in the same class as the E-class in terms of luxury. It's a hair smaller too, but the amount by which it beats the E-class on mpg shows that if Ford did make a slightly larger, more luxurious vehicle with the Fusion Hybrid drivetrain, it would still significantly beat the E-class on fuel economy and performance.
I don't agree the MKZ is comparable to the E-class, the MKZ is a full-sized vehicle, it's more comparable to the S-class in size.

Can't you read? I came up with the real life mpg of this diesel, backed by a source. And hybrids do worse than EPA?
Camry Hybrid: EPA = 34 mpg, observed = 36 mpg
Fusion Hybrid: EPA = 39 mpg, observed = 43 mpg
Only some hybrid SUVs do a bit worse than what EPA says.

Half?
VW Passat: 14 cu-ft
Camry Hybrid: 10.6 cu-ft
Fusion Hybrid: 11.8 cu-ft
Data from Edmunds. Certainly you loose some. But not half.
> If you compare the Mercedes to those it beats the pants off them.
Yeah, by performing worse while being of the same size.

This is scary. You bring up HEAVY DUTY HAULERS to the discussion about passenger vehicles and then accuse me of "handpicking of information".
Where diesel engine belongs are exactly heavy duty applications: trucks, haulers, construction equipment, trains, generators...
> is getting very tiresome.
The only thing that is getting tiresome are Abualsamid's posts that blatantly lie to American customers about diesel mpg. And the lies are glued into the headline. The author does it because he knows very well that:
- everyone reads the headline
- much less people read the post
- just few know European fuel economy cycle is a scam which overestimates mpg of just every car that goes under this test
so putting a fake mpg into the headline has perfect misleading power.

This is brilliant, we getting one in the US? Eh?
See, I like diesels, because they have a stick shift, that means when you put your foot down the revs go up and you go faster, as apposed to automatics, where you put your foot down, you wait, you wait some more, and then "WHAT? NO! Thy did it shift into 3ed and jump to 5,000 RPM? I wanted to go faster...not THAT faster"

You don't have to worry about the revs jumping to 5,000 in a Diesel, no matter what the transmission.

Use the manumatic interface-pick your own gears.
Did you see the press release for the A5 sportback?
The 'new' 2.0tdi claims to rev to 5400rpm?
Not that is actually makes any power up there, so if you forget to upshift when accelerating, or miss downshift 5-2 when you want a 5-3, or 6-3 when you want 6-5?

Why doesn't MB just offer a better lineup, with smaller engines?
C-class: 2.5, 3.0, 3.5 V6
E-class: 3.0, 3.5, 4.7 V8
S-class: 3.5, 4.7, 5.5 V8

Yeah, but still, I like me telling the car what to do, cars that drive themselves are mutinous bastards that will stab you in the back.
Now my issue with Mercedes with small engines is that they are heavy. I like small engines on small cars, not on big ones.

Ok a serious comment on the styling of this car...
For the first time ever I look at a new model year for a MB E Class and it strikes me it's a copy of the styling for the latest (USA) Honda Accord.....
The world has come a complete circle..
