2010 Mercedes-Benz S400 Hybrid Will Achieve 26 MPG

I'm not sure what to say other than "that's disappointing".

Ahhhh, Ummmm. LMAO No Comment. Interesting news, nonetheless. I'll stick with the LS...Thanks anyway.

Not excellent but not horrible either! At least it has not compromised trunk space for the hybrid version and there are noticeable gains over the non-hybrid version!

What, exactly, is the source here because it seems very unreliable? Everything else I have seen is putting the S400 at an average of 30 mpg. This link is to some second rate blog that, as far as I can tell, does not have any citations for where it came up with this info. I will reserve judgment until a reliable source can be quoted.

The numbers are from fueleconomy.org

if i can get a penny every time i hear "my car get better than EPA rating"...


just because you get better than EPA rating, it doesn't mean everyone get better than the EPA rating. i can get 30 mpg out of my 300 horse engine, but i could be getting 18 mpg if i push it a bit on the local road. EPA is a standard test that simulate majority of road behavior. it is an average, an indication. to sum it up, if you can get better than EPA MPG from your vehicle, chances are, you can getter better MPG from other vehicle as long as you drive it in the similar fashion.

This link: http://www.youtube.com/watch?v=1StdN3GSIC8 talks about 7.2L/100km, which is about 32.6 mpg.

Reports 23/33 (27 comb) mpg


Finally: http://www.hybridcars.com/vehicle/mercedes-benz-s400-hybrid.html
On the European test cycle, it achieves 30 miles per gallon (7.9 liters/100 km)—not bad for a full-size sedan weighing well over 2 tons. Claimed CO2 emissions are 190 g/km.

Well of course, the European cycle has always been less conservative.

This title is so stupid. It claims the S400 "WILL" achieve 26 mpg. I hate it when it "sources" tell me the fuel economy a car "will achieve". It's pointless. Even a hybrid is at the mercy of the person behind the wheel and their driving style.

I don't care what this source says. The person behind the wheel makes all the difference. My parents have a 2002 Mercedes E320 and it was rated at 11.3 L / 100 km. On average we are getting 8.2 L / 100 km and we don't even drive it like saints. When my mother drives it though, we get as low as 7.7 L / 100 km (once she even got 7.0 L / 100 km!!!!).

I agree. Predicted fuel economy is a pretty stupid thing.

So just to be clear, this 280 horsepower benz only gets a combined 21, while the 438 horsepower AWD LS600HL gets also 21 combined. hmm. quite disapointing for the benz

Wait. It's a V6 hybrid, but it only gets 19/26, and with lithium batteries??? They do need to license the hybrid technology from the Toyota Camry Hybrid.

The S400 uses a simpler hybrid system and the Camry and S class are in different classes. The upcoming ML 450 hybrid will have a more sophisticated hybrid system.

Wow, the same combined MPG (21) as the Lexus LS600hL. So this is what LiIon batteries are giving us. Isn't this about 2 seconds slower 0-60 as well? And the Lexus is AWD. Good job Mercedes.

you're right about the numbers on this vehicle being disappointing, but you're wrong about the Germans and their diesels. The issue here is with THIS hybrid, nothing more.

The S400h gets 19/26, weighs 4000lbs, does 0-60 in the mid 7's, etc. Well an X5 diesel is ALSO rated at 19/26 and compared to the S400h it's heavier, less aerodynamic, has all-wheel drive, and is quicker. BMW's upcoming tri-turbo diesel produces 306hp and 440lb-ft and gets 6% better fuel economy than THAT engine. It'd be perfect for an X5 or 7-Series. No loss of trunk space, great performance, great fuel economy. Oh, and they're a LOT less expensive than the hybrid versions. An LS600h costs $35k more than an LS460. A GS450h costs $10k more than a GS350. How much more is a diesel than its gas counterpart? Usually $2-3k. Big difference.

There's nothing wrong with diesels other than America's public perception of them, and the spin put on them by people like you who are blindly loyal to their "one brand uber alles" mentality because they're either employed by them or just plain ignorant. And before you hop on your soapbox and declare me a BMW loyalist, I'll be just as critical of the 755h when it comes out if it costs a fortune and doesn't offer any appreciable upgrade over the 750.

Ghosthunter - All of those numbers are estimates and have nothing to do with driving style. In addition, those magazines/car reviewers will drive the car harder than the standard consumer and harder than the EPA criteria for estimation, so if they get a higher number then it is obvious that the EPA estimate is way off. I did not say that the car got better numbers than the EPA estimate, I said the source seemed inaccurate as every other estimate (not reality - read closely before acting like a jerk) placed the average around 30 mpg.

Please also note that this is an "Estimated" New EPA fuel economy and not a "Tested" EPA rating such as on the LS 600 hL. In other words, they are simply estimating these numbers and have not performed that standard tests. Thus, you cannot compare the numbers yet, wait for the lab testing to take place.

Finally, to all of you who knock these numbers, they do have a sue and are important. I agree that the real world numbers will differ based on driver, road conditions, etc. However, the standardized laboratory testing gives us the ability to compare cars in a controlled in environment to one another. This is the use of these tests and it is very important. Once the testing is complete, then all of you can pass judgment. However, passing judgment and saying the car is a "disappointment" is premature given that you are comparing apples to oranges.

small thought, but don't the Hybrid Escalade/Yukon's get 21mpg combined? ;) Pretty sure they have more power too lol

There was so much outrage about the LS600hL being a "disappointing" hybrid, and yet this less-powerful S400 doesn't appear to be significantly better. The one thing this news reinforces is that...

...miles per gallon will vary based on a number of factors.

Drive both the LS hybrid and the S Hybrid like sports cars, they'll both get less-than-impressive mpgs. Most typical S and LS owners, however, drive like old people.

at 19 26 for the s class hybrid, I wonder what an s300, or s350 it would get that is a big improvement over the V8 but it is a much smaller engine, with alot less performance. Why not just sell, a V6 model here other than the image? The epa ratings im sure wouldnt be that much worse than the hybrid

Ive lost interest in anything merc does.
