well its for the C-class but id better not call that a c class thread or no attention will be payed to that...

For better aerodynamics

Two Mercedes patents that bring significant aerodynamic advantages are being used in the new C-Class for the very first time. Mercedes engineers have invented innovative "ventilated tail lights" which replace conventional spoiler lips. To keep the rear window clean even in heavy rain, and ensure that the driver has a clear view to the rear, the specialists in Sindelfingen have a developed a twin rubber drainage channel in which the rainwater is collected and conducted away to the sides by the slipstream. With a Cd value of 0.27, the new C-Class is the most aerodynamically efficient notchback saloon in its market segment. This is made possible by a number of intelligent details which measurably reduce the air resistance, and therefore fuel consumption. The innovative tail lights with ventilating slits are a good example. These replace conventional spoiler lips and therefore do not compromise the attractive rear-end design of the saloon. This technology was newly developed by Mercedes engineers and has been patented. When the C-Class is on the move, air is sucked in from the underbody and is conducted behind the tail lights to flow out of the small ventilating slits in the lenses. As the tail lights are hermetically sealed against the vehicle body, the air is only able to escape to the side via the ventilating slits. In this way the aerodynamic specialists are able to influence the air flow along the side walls by abruptly redirecting it at the tail lights. Without this sophisticated aerodynamic feature, the slipstream would be conducted behind the rear end of the saloon at the tail lights, causing unfavourable turbulences which negatively affect the air resistance, rear axle lift and yaw characteristics. This is prevented by the "ventilated tail lights" of the new C-Class.

Rubber drainage lip on the rear window: rainwater is sucked away

In addition to reducing the coefficient of drag during their wind tunnel tests, the aerodynamics experts at Mercedes-Benz take care to ensure that the exterior mirrors, side windows and rear window remain clear in rainy conditions, giving the driver unimpeded all-round visibility. Owing to the special air pressure distribution in the rear roof area of the C-Class, a new Mercedes patent is used here for the first time: a two-piece rubber lip as a transition between the roof and the rear window. This features an open channel and a partly enclosed channel. Owing to the pressure conditions at the rear edge of the vehicle roof, rainwater first runs towards the middle in the open channel, where suction draws it outwards. Via the enclosed channels in the rubber lip, it then flows away downwards along the window edging, keeping the window clean even at high speeds.

Hey, look, MB came up with useful technology again!

That window defogger, as that's what it sounds like, seems like a decent idea...But, isn't that what a defogging system is for?

seems like a waste of time and money to me. They'll only stick a spoiler on the C63 AMG anyway deeming this pointless, and honestly what mercedez owner/buyer is gona give a crap about where the air flows around his/her car. They buy merc's for the brand image not the car.

Sounds like a good idea to me. Personally I love this kind of stuff. I think being innovative is part of what the auto industry is all about and a large part of the reason people enjoy it so much. It is important to always be mindful of the future and what we can do to improve it. And, although a new more aerodynamic and fuel effiecient tail light design won't solve all of our energy problems, it's a step in the right direction and evidence of our continued advancement as a people. Keep on truckin Mercedes.

I don't see how the air is supposed to come from the underbody, but it still prawns.

The thing about the attractive rear-end design sounds kind of like salesman talk though. It looks like a KIA from behind in my opinion.

Hasn't this tech been around for years ? It was big in the import scene last year, where you would drill holes in your rear bumper, to stop the parachute effect from taking place. Same principle this ain't it ?

lol :D a KIA...

Yeah... lol. It will probably grow on me, the CL did, but the old C class had one of the nicest rear-ends in world, so it's still a hell of a disappointment.

Another example of German over-engineering....*sigh*

that does look weird when i first saw that i thought that the artist was just trying to make some reflection of light well guess i was wrong.

I would love to know how much actual difference it makes...lol
Apprently Mercedes are developing headlights which face the direction you go in lol..

Didn't another brand, I think maybe Lexus, do that before? Or maybe it was Volvo, or some other European mark. For some reason I remember someone else doing it before :confused:

lol... umm.. BMW's got hat in the E46 BMW:p

developing headlgihts that turn you mean cheeky? well i think Citroen did that first, with their Citroen DS or whatever it was called, it wasnt that good compared to those nowadays but it was defo. a very good option in taht car and in that kind of time, i mean its like 20years or more old...

but ehh, thats cool, but i dont think they will really show those white air when you operate it, i have not much comment about it, its just boring, and its probably what you will expect in Mercs

yeah that's exactly what I meant lol..Merc are just refining them and putting them on their future cars.

oh lol...that was funny...yea, they are trying to do that to confuse others thinking that its a HYPER NEW technology

yeah that's exactly what I meant lol..Merc are just refining them and putting them on their future cars.

20 years!!. damn:eek:

That's a nice idea, but it's just a bit of marketing to make themselves sound fancy. The salesmen will bum on about this idea for ages, telling the customer how fantastic it is, and then they'll probably go and buy the car themselves.

I gotta admit it is pretty clever though.

That's 59 years ago!


Anyways... I'm sure that somebody posted a picture of the ducts for the tail light slits of the underbody of the car... maybe it was something I dreamed. Either way, from how I remember they looked like, I'd say they will defintely need a scoop to grap enough air as they are located in a low pressure area at a shitty aoa.
