Mercedes-Benz is mulling a range of new engine configurations, according to CAR Magazine, including a new straight six. The news comes courtesy of an unnamed engineer who also said that the German automaker is currently planning a range of smaller-displacement, forced-induction V8 engines, as well as a larger selection of four-cylinder options.

The company's larger vehicles will subsist on straight-six power moving forward, if the report turns out to be accurate. Buyers will conceivably be able to choose between single- and twin-turbocharged configurations depending on their power demands.

The report doesn't mention exactly when we can expect to see these new engines in production vehicles, and with no specifics on application, displacement, fuel economy or horsepower, we have to imagine that the program is in its infancy at this point.

      Mercedes Benz going back to straight 6's again and BMW going to V6's must be April fools already.

      That would be cool if Mercedes went back to Inline-6 engines.

        Exactly. The inline 6 is not exactly a new thing at MB.

          exactly, its like all the folks that are shocked when BMW said they were going back to inline 4s. umm people one of the best BMWs of all time was a 4cylinder (E30 M3). People need to learn a little history

      Smart idea. Such a wonderfully well-balanced configuration. The main problem I see is the length and making it harder to maintain an adequate crumple zone in the front of the car. I believe Volvo and Mercedes both figured out a way of making the engines deflect downwards in the case of a severe frontal crash, so this may not be a problem. Most of the cars of my youth were straight 6's, Studebakers, Fords, and various Ramblers. I loved the accessibility this configuration offered, and the economy (if you kept the revs down). Recently I owned a Jeep Wrangler with the 4.0 liter 6, and loved how you could lug it way down and it would just crawl ahead so smoothly. The Germans, of course, perfected the art of building inline 6's. So it makes perfect sense for them to go back to this simple, elegant format.

      hmm interesting bmw is going 4 cylinder turbo charged, whereas mercedes is going inline 6. I wonder which is better....

        Actually, rumor has it BMW is producing a V6 engine for its next M3. So, MB going I6 and BMW going V6....go figure. What is VW group might be up to??? a Y6 instead of the VR6???

      Very exciting news! Since BMW is dropping out, it will be nice to still have straight 6 options available. They tend to be very smooth, torquey, and make really nice noises (GTR, E46 M3, etc).

      If it wasn't for BMW and now Mercedes, the "power idiots" would have killed them. There's more to driving than brute power. There's something called a power curve that runs between 0 and peak HP/Torque. Nissan seems to have forgotten about ditching inlines for v6's. You can't beat an inline for smooth power delivery.

      My first car was a '63 Dodge Dart bought in '73. Although a beater, the slant 6 and "typewriter" tranny were bulletproof. In 1979, I got to drive a BMW 530i from L.A. to Santa Barbara. What a revelation German engineering and the slick inline 6 in that car were. Thought I'd died and gone to heaven. 31 years later, I got a Lexus IS300, with a wonderful inline 6. All my personal vehicles between the Dodge and the Lexus were 4-cyl. Smoothest of the bunch was a 1985 Nissan Sentra with a 1.6L 4 than ran like a sewing machine. Only V8s I've ever owned have all been in tournament waterski boats.

      i don't really believe this but it would be likely they will build a new i6 series to replace the bigger v8s in the long run

      The I6 used in the Trailblazer is still the greatest I-6 ever built. They're buttery smooth and will run for hundreds and hundreds of thousands of miles and never have a single problem. GM quality and reliability is unmatched by anyone. Be American. Buy American. Buy GM

        Your post is especially comical since that I6 that GM used to use was designed by Isuzu. I'm all for buying American-built and engineered products, but to BLINDLY tout inferior American products just because they are (supposedly) built or designed here is both stupid and does no one any favors. Praise the Cadillac CTS and upcoming ATS. Cheer the Mustang and updated Chrysler 300. Point-out awesome small cars that both Ford and Chevy have finally. But at the same time, a TRUE patriot will also point out just how much work Detroit still have to do. Lincoln still has no direction. There has yet to be a hybrid from GM or Ford that really comes even close to being as popular as anything from Toyota. Cars from the Detroit automakers from just a few years ago where (for the most part) crap, so its going to be a long, tough battle to convince folks to even bother giving them a chance.

        you know reliability and smoothness are qualities of every straight 6 right? It's what makes them awesome. Think of some straight 6s, the AMC 4.0 Jeeps used, the BMW M family, the Mercedes M104, the Toyota 2JZ the Nissan L and RB. They are all super reliable, and impossible to kill.

          You forget Ford's 4.9. That was a hell of a motor too.

        My unit was Blazer 4x4 back in 1995 and lord that thing could be driven over snow and mud well. I do miss that blazer. I think trail blazer is my next truck in near future if it convince me it retained good ole blazer DNA on it. Texas

      I never understood why they abandoned the inline 6, such a wonderful engine configuration.

          No, it was over money. The M112/113 have heavy component sharing and allowed a reduction in design costs. Packaging was never an issue, almost all the vehicles were designed to hold a V8 or V12. Chassis and engine development operate separate from each other. In fact most of the engineering departments in Germany have little communication with each other, which is reflected in the variations in telematics systems from chassis to chassis.

      Inline 6 may be longer. Guess what, Mercedes used to look better when they did have inline 6. The "great packaging" lately removed the Mercedes Benz look. M-B needs to eject whatever they did in the last 15 years and just start over from 1994. Pretty much every MB since then has been an abomination. Id rather drive 1994 than 2004, or probably 2014. They used to earn their superior reputation.

        :golfclap: I've been saying this for years now. M-Bs today are sh!t. They are not particularly good looking. The interiors are terrible. Their quality is sub-par, but they still cost a fortune. They are running on their reputation and their stuff from 15+ years ago was better than anything released in the last couple of years.

          "M-Bs today are sh!t. They are not particularly good looking. The interiors are terrible. Their quality is sub-par, but they still cost a fortune. " Bullshit. I come from a Mercedes-Benz family and our experiences with these cars have been very good. Currently my father has a 2010 E350 CGI Sport W212 and nothing you described applies to this car. The interior is good and the car is built to a high standard. Even our ex-2002 MB E320 Sport (W211) that the E350 CGI replaced was an awesome car. Reliable, comfortable, safe and solid and a great interior at that. I had summer jobs at a Mercedes dealership drove virtually all their cars including a handful of AMG products. The worst Mercedes' products I experienced were the first generation M-Class and the the first generation Vito/V-Class vans. The original A-Class and Vaneo were decent cars, if a bit cheap inside. The rest of the lineup was impressive and befitting of the MB badge.

        I have to agree... to a point. Mercedes-Benz are still one of the greatest cars on the road, but they were better in the 80s'/early90s. This goes for engines, desgin,... everything. I want Bruno Sacco to come back. He was the best thing for Mercedes. I'd also like for Mercedes to drop basically half their line up. C, E, S, SLK, SL, G and M are all that's really needed.
