Not sure if the drive train loss and extra weight makes that big of a difference but I definitely feel the 2012/13 TUNED E63 are quicker then the Tuned 14+ ......T or F?

Geno51

F the 4 matic will have less traction issues and spin less at the track the 4wd should have a quicker et. The 2wd will likley trap higher speed though

gaspam

after 115 mph or so, the rwd would be slightly faster.... but it would also be playing catch up at that point to the awd

from a dig on street tires awd is much faster

driveline loss between rwd vs awd is not a big as it used to be due to increases in efficiency of drivetrains as well..... also our awd system is more simple fixed ratio with less components, so less drivetrain loss than a more advanced audi quattro system (more components, more friction, more loss)

in that video it took 23 seconds from start of race for rwd to catch awd.... we know stock cars run the 1/4 mile in about 12 secs at 120mph, so seems in this video the rwd finally caught the Awd car at about 140+ mph since the race ended at 155 mph

so if you live near the autobahn get the rwd, if you dont hit speeds above 140+mph much, get the awd

Geno51

Video proves my point exactly. The 4 matic will smoke it in the 1/4 but the 2wd will trap higher. The cars left the line at exactly 15 seconds into the video. At 30 seconds the 4 matic was ahead by a car still. That is likley 4 seconds past the 1/4 mile. He does not pull even with it until 38 seconds so 12 seconds after the 1/4 mile or about a half mile or more. Just going off the video the 4 maitc is faster in a 1/2 mile also.

All over launch superiority

Isn't the RWD car a 2012-2013 model? Those actually make less HP from the factory than a 2014.

gaspam

the 2014 in vid was non-S model and the 2013 was performance package, so same hp

There's a saying in drag 1/10th at the start saves you 2/10ths at the end

Georgee6086

There both fast and amazing cars! I think the 12-13 would pull immediately if it was a roll race. It is clearly putting more power to the ground. In a drag race the AWD has the initial traction advantage. The 12-13 needs a skilled driver or a drag radial to compete with AWD off the line.

gaspam

listen to gear changes in the vid.... rwd doesnt start equaling pace of the awd until about 3rd gear and doesnt start reeling awd in until middle of 4th gear, so even in a rolling start it would of been pretty even until middle of 4th gear (just in the rolling start, the rwd wouldnt be playing catch up, it would be even)

keep in mind the efficiency advantage of rwd to awd isnt static or linear... at speeds under around 115mph the 2 are pretty close in terms if efficiency, but as frictions and heat builds up the gap in efficiency between rwd and awd starts to widen at high speeds over 115+

people tend to think rwd vs awd drivetrain loss differences are static (like always rwd is 7% more efficient, or something to that effect) , buts its not, at normal speeds awd and rwd drivetrain losses are pretty close, but at high speeds the Frictional torque in drivetrain is greater in awd because its function of speed, frictional surface (more of it in awd) and transmission frictional factor

the Frictional torque in drivetrain is different for every transmission and awd system, but when plotted on a graph in physics class back in college, the efficiency curve shape between awd vs rwd always looks the same, an exponential curve with efficiency being very close the first ~80% of the curve and then exponentially spreading out the last ~20%

Hey Gaspam Have you had your car to the track ? What did it run with your mods? I am in the process of doing the same mods to my car. Already got the UPD cold air kit and ordered the others. What times are you getting. I ran 11.75@122 stock in 3500DA and would love to hit 10s in good air

gaspam

i havent hit the track here yet as just havent had time, but should be around low 11s and around 128mph given my mods... maybe better depending on good launch

hoping to get to the track in next few months though and once i do i will post results as i want to get a baseline before i do turbo upgrade as well

TMC M5

Very nice run..especially with the bad DA.

PeterUbers

With correction for lower da he's at 11.5

Stock

TMC M5

The trap speed is what really jumped out at me...really impressive for the conditions. Would be 124+ at sea level conditions...not to mention how an overly aggressive ECU could significantly pull timing in bad conditions...well beyond just the altitude correction.

Geno51

Thats awesome makes me more excited

Geno51

121.90 to be exact but close enough to 122 lol

2012 merc amg

I pull around 120 mph with my stock 2012 in the quarter with good D/A but best time I can do is 12.10. Obviously I'm loosing some time off the line with just the RWD. Plus being a Wagon is probably slowing me down some with the extra weight.

Geno51

Forsure that extra weight does not help. I was very happy to beat a challenger hellcat that night and a 2016 ctsv awd makes this thing hard to beat for most street cars with out slicks. Also smoked a 2015 gt500 on drag raidials. He even came up to me and was asking what the hell is done to that benz. When I told him it was stock his jaw dropped. He did not believe me so i said seriously look at the back still has the dealer temps. He looked then the questions started flying lol. Once i told him it was a 2014 with 14k miles and I told him how much I paid same as his car he was pissed

proxygeek

How do you figure stock cars run 12s at 120? Do you mean E 63 S AMG 2014+ WITHOUT Race Start? 2014+ E 63 S 4 Matics will run 11s all day long stock so not sure what you're talking about.

proxygeek

And that's with a crappy 1.8 60 foot time!! Nice.

Geno51

I know huh. Could be a factory freak possibly

Georgee6086

Do you remember what you 60ft time was?
