I hope you post these kinds of posts to other members here or I just may feel like you're discriminating against me.

The tech never said it was a DCT, I clearly stated that already, he said it does dual clutch shifting. I find it interesting though that MB of Scottsdale would post that. All of the sudden that site is not credible, the tech I talked to isn't credible, I'm not credible, but you are because... well... you said so.

proxygeek

You guys are funny, you go back and forth, you hen peck each other, you act rude, condescending, and arrogant (but don't call each other names), but that's OK, LOL.

I don't know why, but I am getting a very M3 type of driver vibe from you Me Drive the bestest fastest meanest track car EVA!

It is clear you are trying to get people into a pissing contest

For your opinion to matter we need to see proof, else you are a troll

And to the topic poster. when people say drive what makes you happy, this has a very deep meaning and take it from experience.

A car that is ''faster'' is not always the car that you want to own and drive on a daily basis. you need to figure out your main needs and wants from the car.

Example comfort, daily drivability , seating, speed, maintenance and so forth.

Look at the GTR, many people tried it and moved on...why when it's one of the fastest ?

I actually think what you posted was interesting but then you called me a tool

Was just curious if you want to have a more civil discussion - is there any info other that backs up the double clutching, of course I would be interested to know that. I don't know as much as you guys about this stuff and I think when you're not antagonistic you're posting smart interesting stuff

So like I said any links to that info I would be interested to read -- thanks for considering

And you are right I didn't read your post correctly:

"An MB mechanic told me that MCT IS DUAL CLUTCH SHIFTING while admitting it's not a DCT. He said the bottom line is that one gear is released while the other is grabbed simultaneously. If MB can build a PDK rival, look the F out. They will set world records if they can get it into an E63 S in the future. They will break every stigma about what a supercar should look like."

A lot of superfluous information posted to cover the initial error on your oart. Keep going though. Nothing you have posted above is wrong. I used different sized tires to make up for overly aggressive rear diff ratios in the past but what do I know? LMAO Keep adding "facts" to bolster your erroneous initial statement

Yes I hired someone else to install my turboback downpipes cos in the 9 plus hours it takes to do, I could be earning 5-10 times as much as I paid for that time frame on a slow day. So sure I paid someone to do something I did not feel like doing myself yep my prerogative

TMC M5

Reading comprehension is obviously not your forte. I bought the M5 2+ years ago and got rid of it after almost 2 years. I currently own an E63 S. I love the E63 S... but above 60mph, the M5 is faster..sorry to hurt your ego.

You call people "tools", tell them to hump tailpipes and then you get butt hurt over people being condescending to you?

The difference between DCT and MCT:


The Dual Clutch Transmission

Application: BMW, VW, Audi, Porsche, Acura, others

Marketing names: Porsche Dopple Kupplung (PDK), Direct Shift Gearbox (DSG), Power Shift

The guts: An easy way to picture the workings of the extremely complex DCT is to think of two individual transmissions contained within a single housing, acting as a single unit. We’ll call these two individual transmissions ‘sub-transmissions’.

One of the sub-transmissions handles the odd-numbered gears, for instance, 1, 3 and 5. The other sub-transmission contains even gears, for instance 2, 4 and 6. The two sub-transmissions act on a common shaft, which sends power to the wheels.

But on closer inspection, it’s not really a common shaft: its two shafts, one for each sub-transmission, occupying the same space and virtually operating as a single unit.

How? One shaft, connected to one of the sub-transmissions, is hollow, and slightly larger, and the other shaft, connected to the other sub-transmission, fits inside of it. This two-in-one shaft design allows the two sub-transmissions drive the wheels via the same shaft assembly.

At the end of the two-in-one shaft are two clutches. One is attached to the outer, hollow shaft, the other to the slightly smaller inner shaft. Remember, each of these shafts is attached to a different sub-transmission.

The clutches are computer controlled, not driver controlled via a pedal, and they control which shaft, and therefore, which sub-transmission, is currently engaged and driving the wheels.

If you’re accelerating slightly in, say third gear, the sub-transmission that houses the odd-numbered gears is engaged (in third gear), and the sub-transmission that houses the even gears is disengaged from the wheels, but has fourth-gear pre-selected and waiting.

Shifting up simply disengages the clutch from the odd-numbered sub-transmission, and simultaneously engages the clutch on the even-number sub-transmission, where fourth gear is ready to go.

This happens in milliseconds. Now, cruising along in fourth gear, the odd-number sub-transmission pre-selects fifth gear in the meantime, in the background, so it’s ready when needed.

With two sub-transmissions, a two-piece shaft and advanced internal clutch controls, an upshift actually just changes the currently-engaged sub-transmission at some point after the gear change has already occurred. The gist? Actual shifting in a DCT happens in the background when the driver doesn’t notice, and the perceived gear changes are actually just lightning-fast switches between the sub-transmission that’s currently driving the wheels.

From the driver’s seat: Drivers get smooth, lightning-fast shifts, and no interruption in power flow when gearing up at full throttle. There’s no clutch to press, and since the DCT is compact, lightweight and has no torque converter, it typically offers less of a loss of driveline power, higher performance, and improved fuel economy, too.


The AMG SpeedShift

Application: Mercedes AMG

Marketing name: AMG Speedshift MCT 7

Dubbed the SpeedShift, this transmission is exclusive to the AMG performance division of Mercedes-Benz. Capitalizing on the best of two worlds, it amounts to a conventional automatic transmission, but without a torque converter.

Instead, to handle application of engine power to the transmission, a compact wet take-off clutch system is used instead. This enables various enhanced performance attributes including faster gear changes, more instant and direct throttle response, and functions like Race Start, a form of launch control used for maximum off-the-line acceleration in a motorsports setting.

In more detail, the Speedshift MCT 7 uses a multi-plate wet clutch, meaning it contains several clutches stacked on top of one another, operating as a single unit, and floating in an oil bath for cooling and durability purposes. Importantly, the clutch used in the Speedshift MCT 7 is operated by a computer and actuators, not the driver, so there’s no clutch pedal to press.

By doing away with the relatively inefficient torque converter found in a regular automatic transmission, which wastes energy as a result of having to drive fluid through its various components, the SpeedShift transmission is basically a hybrid setup with components of both a manual and automatic.

Notably, this setup does away with the slippage characteristic of a torque-converter equipped automatic, providing the driver with faster, more precise off-the-line responses to throttle inputs.

From the driver’s seat: Drivers benefit from convenient, fully-automatic operation when required, though various performance modes can be engaged when appropriate.

The low rotating mass of this transmission, thanks to its lack of a heavy, fluid-filled torque converter, means accelerator movements are translated instantly to forward momentum.

Further, gears change in eye-blink speeds, and the Race Start function pre-revs the engine and quickly engages the clutch to blast the vehicle off of the line in quick order.

lol i admitted to sayid that i thought he was referring to final drive ratio, not rear diff ratio... nothing erroneous about that

lol 5-10 times as much? so you make ~$8,100 a day (shop rate $90/hr, 9hr job x 10) or $40,500 a week (assuming you are only slinging 5 days a week)? i highly doubt it since you mentioned turbo kits being to pricey... i dont think people that make $2.1 Million a year (on a slow year) find 10-20K too pricey

bro with that $40.5K per week you are making you should send your car off to GAD and have them build you a 1100whp car like vasily's

notatroll

Youtube videos of roll racing says otherwise. M5 accelerates faster.
Dont be upset, there are many things that the e63s does better than m5.

kponti

I misspoke (my math was off), that's on a good fast paced day not a slow one (even though I did say can, but lack of reading comprehension to bolster some idiotic point of yours is been your forte). But even on a slow day, well worth having someone else do it. Its a 4 door sedan weighing over 4300lbs, no GAD for me, financially dumb for me for my daily driver.
Oh and nope not me talking about turbo kits being too pricey, too pricey for my RWD daily driver? Yes! (can't see the point to be honest). But then again, another way to bolster some bull**** point of yours.

proxygeek

I didn't bother to read your drivel, LOL.

I find it funny that you dumped your M5 to go into an E63 S.

I have raced a standard F10 M5 on the freeway with paddles and beat it, yet somehow it's faster. Given a decent driver (driver being the key), the E63 S is faster.

The F10 is a dog off the line compared to the E63 S.

I guess coming from a 911 Turbo, I am just partial to AWD.

proxygeek

The YouTube videos are mostly a joke. I have noticed the roll races you speak of are with auto shifting and not with paddle shifting. A good paddle shifting can beat the M5 on the freeway, and I know, I have done it.

The MCT is no where near as good at determining the best gear to be in compared to the DCT. Therefore, I challenge any of you to practice your paddle shifts (like they use in DTM) and go race an M5 on the freeway. You might be surprised. I think too many people try and race fast RWD cars with auto shifting.

Both Motor Trend and Road and Track have both tested the E63 S and say it's faster and it is. So don't believe me, but when you start doubting reputable car mags, it's a little ridiculous.

The M5 is a nice car, but it's not as fast as the E63 S and countless sources have said so.

proxygeek

Thanks for your incredible words of wisdom.

nynd

I don't think that's funny as I did the exact same thing... I think we're actually privileged to get behind the wheel of different cars.

notatroll

You are such a troll. Find me a single video where e63 beats f10 m5 stock for stock from a roll.

TMC M5

You know what I find funny...is that you claim that you didn't bother to read my "drivel", yet you still quote me and attempt (and I use attempt very loosely here) to take me to task on my content. But you always seem to come up short on your facts...and claim antecdotal "evidence" of beating up on M5s. I provided vbox data that was verified. Show me a stock (drop in filters/mufflers) E63 S with a better 60-130mph time with an under 3% slope.

proxygeek

There are always holes in your logic and nearly everything you say, it's not hard to take you to task! LOL!!!!!

Seriously, there are just numerous sources that the E63 S is faster in like 5 different categories but you will die to make the point that it's faster on a roll. Ridiculous.

proxygeek

You're ridiculous you know that? Just ridiculous.

You "On a roll" bunch really get on a roll.

proxygeek

Indeed.

These are fast cars and while I really like the M5, it's a beautiful car, I just can't stand it when people make a car more than it is. The E63 S is really just a bonkers car.

TMC M5

Sorry, no holes in my logic... I can't say the same for yours since your arguments are based on an emotional defense to justify your purchase. If you want pure independent data from impartial parties, okay I will dig it up for you. Even though I know you will come up with some other outlandish reasons to dismiss it since it does not support your agenda (like how I show you dynos supporting my statements and then you dismiss them as being falsified).

+1,

[---YouTube NOT always honest measure or prove---],

if you notice something; most M5 or any other BMW fans wins a competition, with "MB's or Audi's",

they put their clips immid. with BIG smile on YouTube, or on their own forums..!

but when they lost, they didn't admit, they have many Excuses in their pants packet..
