Why is m5 faster that e63s
Most people don't care about roll racing and the ones who do are tools. You don't measure a car's performance on a roll. Car makers don't, car magazines don't, almost no one does.
The famous "On a roll" discussion is on every car board and has been for years. It gives people something to bull**** about.
So which gear ratio will result in a final ratio of 3.06 may I ask? IE which trans gear can you multiply by 2.65 axle ratio to get 3.06 final ratio?

Yes the wagon has a more aggressive rear diff ratio of 3.06 but nowhere in this thread have I seen references to a wagon. I have only seen sedans that are still 2.65. Stop using round about arguments to bolster your erroneous post.
And since we are quoting magazines, let me also add that Edmunds has the final ratio of the E63s at 3.42

Most people do care about roll acceleration and most people do measure cars performance on a roll. Where the cars are not limited by traction and its pure game of engine power, transmission/diff gearing and aerodynamics. IMO
Final drive ratio is simply a multiplication of the rear diff and whichever Trans gear ratio you are using for your calculation. Helps you determine what tire size to use, completely DOES NOT use tire size for calculation, helps you determine what tire height to use
But keep up with your misinformation
I know you're out there roll racing and have posted lots of vids of you racing pretty much everything out there that's fast
I trust your judgement over all others!
I got your "Light mods and the car will run this" BS and you really didn't make much of a point.
So go hump your F10 M5 and dream it's faster than the E63 S, in reality it's not and it's indisputable.
The Best of Mercedes & AMG
Essentially every other credible source (that is not proxy's tech) says its a 7g tronic with a multi clutch wet clutch in place of the torque converter
And benz' talking about the dct

The MCT is a great transmission but DCT is on another level. Try one. The downshifts are what makes the difference between DCT and MCT. Its not about numbers
AMG must have realized it cos everywhere they could put a DCT, they did!
Juuuust wish it engaged a bit better in stop and go scenarios and wish the throttle tip in didn't have the well know delay... But sprint booster really helped my perception of throttle tip in
I find the dct in the cla clunky and annoying in daily driving traffic

Now can final drive ratio be calculated without tire size? Of course it can... But also, yes, tire diameter has an effect on final drive ratio.. i wont try and explain it to you because its obvious you wont get it but if you want to read up on it, here's a more reputable source of mechanical know-how vs ehow.com lol btw your link was for motorcycles since it was referencing primary gear ratio as one of the inputs

here's a litte snippet (keep in mind final gear ratio and final drive ratio are not the same thing, but I'm sure you already knew that)
"Tire diameter will also have an effect on a vehicle's final drive ratio. As tire diameter changes, so will engine rpm at a given speed. We can demonstrate this with the simplified formula: rpm = (mph x final gear ratio x 336*) / tire diameter. For example, given 65 mph, a tire diameter of 30 inches, and a final gear ratio of 4.10, the engine speed will be approximately 2,984 rpm--(65 mph x 4.10 final gear ratio x 336) / 30-inch diameter tire. If we reduce the tire diameter to 25 inches, the engine speed increases to 3,581 rpm. By installing shorter tires, the vehicle will accelerate as though it has a 4.73 (higher numerically) gear without the expense of gear swapping."
you can also approx final drive ratio using formula of Final drive ratio= (engine RPM @ 70mph/ top gear ratio)/ tire revs/mile .... (1750/.73)/784 = 3.0577 ... lets just call it 3.06

its clear you've never changed a ring and pinion in your life.... tire diameter has an effect on final drive... i wont try and explain it to you because its obvious you wont get it but it you want to read up on it, here's a more reputable source of mechanical know-how vs ehow.com lol

I used to take my previous car to the drag away and a few buddies would bring smaller rims for their drive wheels
... a few 10 second runs prob arent going to set off the abs, but drive it long enough and eventually it might.... but then again its dependent on the car and system.... i can put whatever i want on my cj7 and it will never affect the abs
my c63 would only trigger abs/ traction control error randomly after the tire size change and only on corners. when i changed down one size went away forever.... other guys with same year c63 never had a problem with same larger tire combo... gremlins
People overpay for things everyday and then rationalize to themselves why they did it. The F10 M5 is a nice car as I have said, but they are way too much for what you get. Just like the ridiculous $135K M4 GTS.
