When Mercedes introduced its 7-speed transmission, the German automaker launched a new era of multi-geared auto-boxes with all other luxury automakers taking part in a bid to offer increased performance and fuel economy. Lexus responded with an 8-speed automatic transmission, Infiniti developed a 7-speed box and both BMW and Audi now have 8-speed units as well. So what is Mercedes to do if it wants to stay at the top? Develop a 9-speed of course!

And that is just what engineers at the luxury automaker are doing, reports AutoCar. According to sources inside the company familiar with future engineering products, a new 9-speed automatic transmission is being developed that will drastically improve fuel economy.

According to those same sources, the new slushbox will be used on large displacement engines, meaning that it will most certainly come equipped on AMG models. Anything more than a 9-speed is unlikely though, as engineers believe that along with certain technical obstacles, consumers don’t want that much shifting.

The insider source gave no clues as to how far along in the development phase the new 9-speed unit is, or when we might first see it on a production model.

La bonne vieille transmission manuelle est de moins de moins souvent utilisée en matière de production automobile, souvent au bénéfice d'une transmission automatique et, depuis quelques années, des nouveaux systèmes à double embrayage devenus fréquents. Chez Mercedes, on serait carrément en train de mettre au point une transmission à...neuf rapports.
Oui vous avez bien lu, neuf rapports au total pour une nouvelle transmission automatique qui serait actuellement à l'étude au sein des bureaux de la marque à l'étoile, selon nos confrères anglais d'Autocar.

MB mentionne qu'une transmission de plus de 9 vitesse est trop difficile et inutile. Mais je suis prêt à parier que si Lexus introduit une transmission de 10 vitesses, MB va répliquer avec une transmission de 11 vitesses et ainsi de suite.

Après c'est quoi, ils vont faire comme les vélos? 18 vitesses c'était hot dans le temps, maintenant je sais même plus on est rendu à combien 24? lol
 
I don't want to sound like a smart ass, but semi-trucks have 7-8-9 gears typically. The biggest ones do indeed have 18 gears. I don't know what MB plans to have its consumers lug around in their vehicles, but I'll stick to my era of 5-6 speed. I think that it will do for years to come.

On santent que la clientel visier Cest pas Du monde qui von ouvrire le houde pour montrer le moteur a ses amis.
 
imagine if it was manual and shifting 9 times lol and sooner or later lexus will come out with 10 and who knows anymore
 
At the end, everybody whips out their precious to see who's got the biggest LOL, the wiener wins, but hey!!!! who the funk needs 9 speed on a car, wtf?
some fency shit involving money they should put in R n D for some other stuff. blaming the fuel economy but they putting it on the bigger engine, at the end... its not an economical issue but a 'who's got the bigger dick'' sounds stupid to me.
 
Dans pas long, on va entendre des compact car shifter des plateaux comme un tracteur de van. C'a pu de sens.... on est loin des bonnes vieilles Powerglide 2 vitesses à colonne!!
