Mercedes-Benz, longtime stalwarts of the V12 engine, is considering lowering its preferred cylinder count by a third. While our first inclination is to assume that this change is being made to increase the fuel efficiency and lower the emissions of the overall Daimler line, the real reason that the bent-12 engine program is being dropped is simply because the block is too long. A V12 is, for all intents and purposes, the same length as an inline-six, and the German automaker's latest line of mainstream engines are all in a V-design, so its cars are no longer being designed with an engine compartment large enough to house such a lengthy engine. Fear not, power fans, as the company isn't abandoning high horsepower in general. The V12 program is apparently being shifted towards twin-turbo V8s, and the magic of forced-induction means there's no reason to assume that fewer cylinders will equal fewer ponies. Expect the moratorium on V12s to begin the next few years.

      As sad as it'll be to see it go, the MB V12s haven't actually been around all that long. They were only introduced with the W140 chassis in 1992 (and dropped into the R129 the same year). They'll do fine with the V8s. Maybe they'll bring back the 6.9L designation to go next to the 6.3.

      I have to wonder if they'll continue making the existing models for Pagani though.

        Daimler-Benz had a hemi V12 in 1938, but that little conflict happened. The W147 prototypes had them.

        and even though BMW had their V12 out first in 1987, the MB V12 of 1991 was far more sophisticated.

      Too bad. The V12 (esentially two I-6 engines joined) has perfect primary and secondary balance, which a V-8 does not. Hence the 12 is a smoother running engine without the need for ancilliary devices.

      Interesting how we go from an article reporting Honda eventually having V-8s to Mercedes phasing out V-12s.

      What will Maybach use?

      MB-AMG should go back to its roots, large capacity naturally aspirated engines.
      Sure phase out an old V12 (remember the non turbo 5.8 liter 362hp 391ft-lbs) but in its place, a modern direct injection 4 valve head 7.76 liter V10 (6.2 V8 scaled up) 675hp 600ft-lbs 7g-tronic MCT

      What V12s will be left, the Audi V12tdi?
      If that goes, then there will need to be an epilogue in

      OMG the V12 is going bye bye!!! Like this really bothers me.

      Grow a penis fellas, its a damn engine.
      • 6 Years Ago
      NOOOOOOOOOO!!!! These are some of the best engines available in the world!!! The V12 in the S600 is better than the V8 in the S63, while the AMG V12 in the S65/CL65 is the best production engine ever made by anyone. ever.

      This is a crying shame.

      Jesus.

      Ferrari with going down to V8's

      Audi dropping down to turbo sixes....


      the era of big engines are finally going under...but if you can make the same power with a smaller engine and be more efficent....whats the point of having then anyway ?

        I'll just miss the noise. Very badly. So very much.

        That and the smooth smooth power delivery but that doesnt effect me much since I rarely get to be in any sort of car that has a v12... I have twice though!

        As Jeremy once said on top gear or his online editorials forgot which one, it's for those who are lacking down under;)

      No V-12 will reduce engine compartment size. All of the blowers and other gadgetry will keep the horsepower numbers high. The performance numbers will remain or improve because of new lightweight materials like carbon fiber. Have no fear Benz will still equal fun!

      A V-8 can be made to produce as much HP as a V-12, with better efficiency and less emmissions but a 12 will be smoother. The real reasons for dropping the 12 is its size, complexity and cost.
      • 6 Years Ago
      No matter what configuration they switch to, it won't have the perfect engine balance of a V12.

      EPIC FAIL.
