Mercedes S400 BlueHybrid

Mercedes-Benz S400 Hybrid

The Mercedes Benz S400 Hybrid is the world’s first mass produced car with a lithium ion battery. It’s the first Mercedes with a hybrid drive. And, with a price tag just above $90,000, it’s an ultra-niche vehicle. The S400 Hybrid arrived in US showrooms in August 2009.

Its competition in the nascent luxury green vehicle market is the $90,000 BMW X6 Hybrid (although it's an SUV); the $109,000 all-electric Tesla Roadster (although it's a two-seater); the $87,000 four-door Fisker Karma plug-in hybrid (not yet out); and the $104,000 Lexus LS 600h L—a V8 hybrid averaging 21 miles to the gallon. Lexus annually sells about 1,000 units of the LS 600h L.

Mercedes S400 Hybrid Mercedes S400 Hybrid

We achieved 29.3 miles per gallon in the Mercedes S400 Hybrid, over a 150-mile mixed driving course though Southern Germany.

The offical EPA mileage number for the Benz S400 are 19 in the city and 26 on the highway. HybridCars.com did our own mileage test of this big luxury sedan on the roads of Southern Germany. Our drive loop took us from Stuttgart—the home of Mercedes Benz—to the town of Buel and back, a round trip of approximately 150 miles. The route was evenly comprised of high-speed driving on the Autobahn—where we ran at, ahem, greater than 100 mph—as well as moderately paced rural roads, and narrow streets through smaller hamlets. We achieved an impressive 29.3 miles per gallon—not bad for a car that weighs almost 5,000 pounds. (By the way, the V6 of the S400 is plenty strong for the Autobahn.)

With much stricter speed limits in the US, it’s reasonable that fuel economy results will be even better. But saving fuel and money is not the first concern for buyers of this car. The buyer of the S400 hybrid is probably just as interested in pairing the Mercedes three-pointed star emblem with a hybrid badge, to demonstrate a combined interest in luxury, refinement, and green status. Mercedes claims that the S400 is the “CO2 champion in the luxury class,” emitting a relatively low 186 grams of carbon per kilometer.

As the hybrid version of the Benz flagship S-Class sedan, the S400 is powered by a mild hybrid system with a 3.5-liter V6 gas engine. The hybrid system allows Mercedes to maintain its high-power profile, while using a V6 instead of a V8 or V12. The electric-gas combo provides a total output of 295 horsepower, channeled through a seven-speed automatic transmission. Benz is particularly proud of what it refers to as “compact” batter technology. Engineers made this hybrid system as well-packaged and light as possible. (Mercedes-Benz was able to fit the entire pack into the same space, at the right-hand base of the windshield, that previously housed the car’s standard lead-acid 12-Volt starter battery.) The S400 weighs only about 120 pounds more than the standard S-Class.

Driving Manners

The S400 drives much smaller than it is. Cutting through the tight twisties of Germany’s Black Forest, this hybrid cornered flatly and with confidence. It is as nimble and agile as its gas-powered counterpart. Stability comes from Active Body Control, an active suspension that continually adapts the suspension tuning to the current driving situation. The S400 features Torque Vectoring Brake, as well as Crosswind Stabilization, both enhancing the sure-footedness of the car. Other high-tech advancements include a pre-collision system, adaptive high beam assist, lane keep assist, and radar-based cruise control.

The cabin of the car is as plush as the standard S-Class. It shares all the same luxury features including a new split-view driver interface, which allows the front passenger to watch a movie without distracting the driver. There’s also a “Night View Assist” feature that detects pedestrians on the road ahead. The only interior difference is the S400’s hybrid gauge showing the flow of power between engine, battery, and regenerative braking.

The S400 shares the look of the S-Class. Signs of its recent facelift include a more aero grille, revised LED lighting at the front and back, and new mirrors, tailpipes, and wheels. The Mercedes Benz S400 hybrid is a luxurious, fuel-efficient saloon with lots of driving appeal. With its steep purchase price, it’s obviously not for everyone—but it is one more option for uncompromising affluent buyers seeking a slightly greener ride.

Yes, diesel cars get better mileage, but didn't I read somewhere that it requires 20% more crude oil to produce diesel vs gasoline? If we compare diesel burners to gas burners, how much less diesel fuel must they burn before we break even in terms of oil consumption?

I have a 2007 E-320 and it gets 29 mpg (average). Best car I have ever had. Waiting for a diesel hybrid plug-in from Mercedes and I am sure they will make one in the next few years.

This is a trick: the same amount of crude is used. Diesel is less refined than gasoline. Diesel takes less money to refine.

Perhaps you haven't heard of the recent problems with Toyota accelerators. Just yesterday, a man was unable to stop his Prius, furtunatly the police were able to stop him and he was unharmed. So yes, it is less expensive, but what is money in comparison to your life??!!

I enjoyed this brand new Merc S400 hybrid on June 2010 when just arrived at Taipei International Airport and picked by the Grand Hyatt hotel limo.
It was really a memorable moment (one hour ride to the hotel) and I just said to myself that I have to own this incredible car soon!

No, you cannot compare an advanced high quality Honda with an oldfashioned medium quality Mercedes, never! R u guys serious or really that ignorant?! Light weight Toyota Prius has a 36 hp electric motor whereas this heavy stone age Merc has a tiny 20 hp! Prius has a continuously variable transmission whereas the Merc has a conventional automatic! Mercedes, like BMW, simply doesn't have the tech dick to perform a decent hybrid passenger car. This is why they have to relay on Toyota! Remember that the first Prius hybrid came 13 years ago (when the Euros couldn't even spell to hybrid), and that 9 years ago a Toyota van (Estima) was equipped with an AWD hybrid system connecetd to a continuously variable transmission that Daimler or BMW can't still produce! Wake up guys, you're an embarrasment for your girlfriends! Check my page, it was made long ago but still rules!

Absolutely not true. Diesel takes less refining than gasoline. It's probably the other way around, gasoline takes 20% more crude oil.

For the Gentleman that prefers a Toyota or a "Nissan over a Mercedes, then I say to you.."More Power to You",, if you like "shake and break cars". In 1987 I purchased brand new off of the lot, my first Japanese made engine in a Dodge Vehicle body, and it lasted 99,000 miles before the timing belt, and the 4/4 drive train went belly up. However in 1992, I purchased my first Mercedes 1976 300SL..with 250,000 miles, and vehicle repair reports, and the only parts that had been replaced were the spark plug wires, plugs, and tires. The only thing that was broken were the chrome door handles. The car's engine performed like a new engine, and the ride was as firm and as soft as a Lincoln Towne car or Lincoln continental with air bag shocks. The only non performance that the car represented was it's inability to withstand the crashing of a giant tree upon it's top,,(LOL). My second all time experience with vehicles was with a 199,4 3.3 liter ply mouth grand voyager; and I retired that vehicle in March 2010, after 360,000 miles on the body, and 225,000 miles on the first engine. I did replace the engine after 225,000 miles and later the transmission and drive axle.
The second engine was from a 1995 grand voyager, with 35,000 miles when I had it extracted from a wrecked vehicle, there by giving me 135,000 miles of service before I retired the vehicle. My former experience with ford vehicles were similar in mileage to the voyager, and Mercedes engines. To summarize this comparison of apples to apples.. with the four styles of vehicles that I am referring to, I vote Mercedes to be at the top of the list, Chrysler and Plymouth next in line, with Ford running a close third. So my question to all concerned about the Mercedes' reliability; How should I rate the Japanese engine in this scenerio? I think they are shake and break vehicles,,Myself..and the only domestic semi luxury car that comes with reliability are the European Cars, such as Mercedes, BMW,Austins Martin,The former MGB, etc, and American Traditional Vehicles..Surely you can count on Lexus, and Acura, but that is not in the class of a toyato hybrid that you are comparing the Mercedes to. Try a real car instead..Dude

There will no doubt be some rich people who do not care for gas prizes, do not truly understand what it means to want to save the environment, but want to appear green. For those people, this car will do.

I must say that I am truly disappointed by Mercedes' lack of effort trying to produce less gas guzzling cars. 29 mpg can be achieved by even gasoline-only cars. Of course, I do see that a gasoline-driven car with that performance will no doubt use even more gasoline, but isn't that precisely the point? It's irresponsible to market this car in light of the circumstances we are in. Mercedes, of course, will sell this car because they can and because there will be a few people going for luxury, performance, pseudo-eco cars.

For my part, after having grown up in Germany, and waiting to buy an environmentally friendly German-made car (now that our financial situation is improving: career etc.) for years, have come to the conclusion that German car makers in general will not serve my needs.

Although it pains me, I will vote with my wallet by NOT giving my money to a German car maker, but a Japanese car maker. Their hybrid cars will in the near future produce hybrids with mpgs in the 60s to 70s which is the minimum threshold for my next car.
