Why Inline 6 Cylinders Are Better Than V6 Engines - A Comeback Story

Motor

How engine downsizing saved the inline six-cylinder, and why companies like Mercedes are switching from V6 to Inline 6 cylinder engines. Inline six cylinders have many advantages over a V6 engine.
The Mercedes M256 engine is the result of a feel-good engine-downsizing story. You read that correctly, engine downsizing has in fact brought back a very popular engine style to the Mercedes line-up. Since inline four-cylinders are becoming more and more popular, creating an engine variant with two additional cylinders lopped on is a great idea from a production standpoint. But not only does it save on cost, inline-six cylinders have many advantages versus V6 engines. Check out the video for a full breakdown of the differences.

    inline 6es are the definition of balance and smoothness. i wish i6s were even more common now. i'm hesitant to move towards downsized engines in trucks but if the 3.5 ecoboost was an inline i'd be a little more open 😍

Thus, no double sunroof, no 9G-Tronic transmission, no beautiful sound of I 6-cylinder engine, etc. Don't cry, my over Atlantic bro...just go and buy this car, drive him nicely and after 3 years sel him to Europe for 110 K USD

    It's a real shame that they reduced the cylinder diameter, because with the old size they really had a lot of experience. I mean, Germans have been boring at 88mm for about 80 years! :-P

    The mild hybrid system and the electric supercharger are cool, but I don't agree with merc benz on the electric water pump and AC compressor. Just more motors to break imo, and converting mechanical power to electrical then back to mechanical is less efficient than ideal. I dont think it's really that hard to have a crank driven water pump. The engine still has to have cam timing, so whats stopping the engineers from having a beefier timing chain to drive the accessories?

    The lane tracking steering issue that is mentioned is the mercedes way of making sure you are still paying attention, this minor tugging on the wheel is the MB check that you are still there and paying attention. I have a MB with the same system and once you're used to it is a fantastic setup. Once a month I have to drive 170 miles, have a karate training and drive back another 170 miles, in the past I would be burned out at the end of the day because of the focused driving required, now with the distronic (keeping distance between you and the car in front) and the lane keeping assist I am completely relaxed after the same trip, just because you don't have to concentrate as much while driving, the car takes care of the mundane part of the trip (keeping distance and staying in your lane).

    Loved the video and really interesting insights into incorporation of modest electronic componentry to make a real performance improvement. But I think you forgot to mention the coolest thing about in-line sixes : the fact they have 7 crankshaft bearings, one either side of each conrod! More than a V8, more than a V10, the same as a V12. This makes the robustness of the crank up for amazing boost (just like the in-line 4’s you mention, which have 5 mains for 4 cylinders, but difficulties with balance)! Please keep the reviews coming!

    V6 in terms of a design still has many advantages over an inline 6 - much more compact, you can fit it in pretty much any engine bay - short width and length of the engine makes the engine much more rigid which means you can safely produce more power from the engine - better weight distribution (lower CGI and shorter) - more torque @ high rpm - since it’s a very flexible engine, it could be cheaper to buy and maintain than an inline 6 because manufacturers can use them in most of their cars in their lineup which will means that the engine is highly mass produced which cuts down price and well proven which makes them more reliable Disadvantages v6 have over inline 6 - needs counterweights to run smoothly - harder to maintain - inline 4s are becoming a popular engine due to strict emissions, you can’t make a v6 out of an inline 4, but you can make a inline 6 out of an inline 4. - V6s are more expensive to make and less reliable than an inline 6 - worse low end torque

    Having had a few V6 Mercedes and now an Inline 6 (but not with the ISG), I find the inline 6 to be inferior. It's not as smooth running, and acceleration lags a little bit more, giving a less smooth feeling power curve.

    I used google translate to translate integrated starter alternator from English to German, and I got integrierte Startergenerator. The world alternator is not really a technical term. It is more of a marketing name. The technical term would be something along the lines of "an alternating current generator and a bridge rectifier." To make the description more precise, you might say "the bridge rectifier, which uses large silicon diodes, converts alternating current from the generator to direct current that is used to charge the battery and to supply direct current electrical various devices in the car." Or, for short, one could just say "AC generator with bridge rectifier." The thing that is called "an alternator" is not really one device, it is really 2 devices.I would not be surprised if, in German, the word "alternator" is not used.

    Usually I am not at all sad about engine downsizing. My 1934 Chrysler Airflow gets 115 horsepower out of a 5.3 liter engine. My 2015 Honda Fit gets 130 horsepower out of a 1.5 liter engine. I am happy about this. Why? the 1.5 liter engine, despite its smaller size, has a longer life, weighs less, and has a greater power to weight ratio. I can't think of any reason to be sad about this.

    Yeah. Tell to the Alfa V6, 540hp from 2.9 litres, that inline six are better. What you are talking of are downward compromises to save manufacturing costs (Mercedes' buyers in particular should be happy to know that the brand made those compromises to save costs, shouldn't they? It's an economic brand after all...). A long stroke engine is limited in its rev, and the six crankpins required by an inline six reduces the rigidity of the cranckshaft. Performance-wise, the I6 will always be inferior to the V6. To bolt on an electric engine to a gasoline one to make up for its defects doesn't improve the architecture. You can bolt on electric engines to every gasoline one, not only to I6 ones.
