Mercedes-Benz has revealed that it has readied a new generation of its 4MATIC all wheel drive system that can be used with its latest front wheel drive platform. It will debut on the new CLA-Class sedan as well as the CLA 45 AMG.
The new 4MATIC is being combined with the 7G-DCT seven-speed automated dual clutch transmission which was premiered in the B-Class. The electrohydraulically actuated multi-disc clutch integrated in the rear axle gear unit is responsible for fully variable torque distribution.
Operating principle: when the multi-disc clutch is open, the CLA is driven almost exclusively by the front axle for fuel economy. When the clutch is closed, the rear axle comes into play. This means that the drive torque can be shifted in fully variable mode between front and rear axle according to the given situation (torque on demand).
The torque distribution ratio is also dependent on the activated shift programme of the 7G-DCT dual clutch transmission. The ECO programme results in torque distribution of a conservative nature. Less torque is channelled to the rear axle, resulting in gentler handling and supporting an economical driving style at lower revs.
In SPORT or MANUAL mode the activation times are shortened and more torque is distributed to the rear axle in the interests of a dynamic, sporty driving style. On the AMG versions, adaptation of the 4MATIC controller takes place in accordance with the 3-stage ESP.
The gallery has plenty of technical diagrams of the new front wheel drive 7G-DCT + 4MATIC components so check them out.

The best or nothing..
All Germany car best for Nothing.
VW,BMW, Benz.. all no good.. Overpriced item in Malaysia.
gee,disagreed with you..i thk should be the Germany car is good and some very good,just because of Malaysia,price here after tax are much more hikes up..tats why overpriced…
i know you are the best.
Then jst bring the price down in the coming ge.
Let me tell you something, this might be a shock of your life. All cars in Malaysia are overpriced!
I saw CLA interior spy shot..why the heck most new Mercedes model don’t have gear stick on center console!
What are u driving mate? Toyota?
Are you referring to me ? then mine is old E-Class W211 (2008) model…I do drove my dad Toyota corona 15 years ago..
Technologically not new..much like the ACD on evolution series but with much compact package..no AYC similar system though..
Yup this technology not new. What is three stage ESP
Not all German cars are overpriced, but all cars are overpriced !
This system is more or less the same as the transmission unit in the Ferrari FF I think, except the latter is rear wheel biased.
Side note: Technical posts like this usually have less comments than, say, news about Proton. What does than mean? =p
Ferrari FF has a front-longitudinally mounted engine. Quite different. This CLA has a front-transverse mounted engine and more comparable to VW 4Motion cars with same layout. Not new certainly but a first for Mercedes.
I thought FF has 2 transmissions so its totally difference with what’s merc offer
Most of us who can afford will want RWD or AWD vehicles. So please ya, Merc and BM.
Fuel economy < joy.
What 'overpriced'??
FWD merc sedan…then the design proportion will looks like other cheap japanese n korean FWD car like honda,toyota, nissan, kia, hyundai . Its ok if its justifies in lower price than other RWD merc.
it’s still decades behind comparing to legendary Quattro from AUDI
