IS AWD SLOWER THAN THE RWD 300C. sorry about the caps

i did a run with a rwd 300c on a m10 in michigan. I was using the auto-stick i beat him by about a car length to the next light prolly give or take a minimum quarter mile. I am not sure if he is a good driver at all or maybe the auto couldnt keep up with the gear shifts. But if it was good driver vs good driver on both the varities of 300c which one would win or atleast according to the specs which one would be faster.
:confused: :confused:

Admins sorry if this was posted in the wrong place.

I believe the AWD uses Mercedes 4-MATIC transmission where the C uses the 5 speed Auto Stick from Benz. As far as real world performance numbers, I don't know, but perhaps the 2 different transmissions are to blame for the discrepancy, of course, if I was you, I would stick with the "I'm the better driver" reason ;)

The AWD has the same 5 speed tranny as the RWD. 4-Matic does not mean 4 speed transmission it meand all-wheel-drive.

In a street race you have no idea what the other driver is doing or how hard he is pushing his car. The AWD is slower because it is heavier.

Joe just to let u know i have black 300cawd as well hence my name. i paid 45k with higher warranty and with every accesory chrysler provides on this car including u connect. I do have bigger tires rated at 245x55x60. These tires are ultra performance summer(no i aint crazy driving summer tires in michigan i know what i am doing :D ). in the situation i explained i was doing the shifting on the car where as he probably was not using the autostick he was just pushin the gas i was manually shifting the gears depending on the rpm and engine noise(this is the best way to shift i assume for autosticks). One more thing is this goddamn auto stick i was driving with the autostick on the 7mile and suddenly the car hit the bump and my hand moved left and i downshifted the gear and the whole goddamn car shook(which in technical meaning "u stalled the car"). Check engine light came on but it went away next day. But please read this situation and let me know whatsup. Oh yeah his foot was the accelerator, i think i can tell when the hemi is screaming at the top of its lungs. Could autostick make much difference in 0-60 times.

I'd heard the AWD has a slightly lower gear ratio in the lower few gears. As well, the AWD is apt to grip more than the RWD from a stop.
There are no 4-Matic or AWD cars faster than their RWD counterparts with the same engine. 4-Matic is for bad weather - it is not a performance feature.

AWD/4WD is heavier by several hundred pounds, this is why it is slower, in all cases. Most autostick/ tiptronic manumatics are slower in straight acceleration with manual shift in most tests I have read. Best times are achieved by brake torque and mash the pedal to the floor. The manumatic is great for holding a gear e.g.dropping from 5 to 3 on a two lane pass. I don't know if the C is faster in manual or auto, I'll post my results when I go to the track this spring.

Well, I just have to chime in with my fine opinion that AWD can be considered a performance feature: it is faster in CERTAIN situations - i.e, wet, icy, slippery or "twisty" conditions.
AWD Audis drive the wheels off of their competitors in European racing just 'cause they have that performance "advantage" (weight penalties notwithstanding).
AWD also keeps you on the road when even the best drivers (like myself) end up "in a ditch like some cheese-eating high-school kid." NOT!

This is just my 2 cents on this...

I've heard that the best way to get a solid launch out of the car is to turn the ESP off, and to put the car into autostick mode while leaving the autostick selector at 4. Then powerbrake and launch.

The AWD may grip better initally but the RWD will be faster because of it's lighter weight. I liked the AWD version and almost bought one since I live in MN, but decided I liked the virtues of the RWD car better... (Wheel gap, rims from factory, weight distrobution further from 50/50, RWD dynamics)

Just my opinion, but I did kind of wish I had AWD when we got 10" of snow a few weeks ago.. =) But in all honesty, the RWD did just fine and got me home great, just didn't have the take off the AWD would from a stop..

Visit this link, I make a decent point about the 4 matic system in the AWD 300C.

In most circumstances the AWD is slower then the RWD. Again I will say 4 matic is made for weather not performance. If we race in rain, snow, mud, the AWD is the better choice.

But lets be serious, I can't remember the last time being in a 4000 pound 4 door sedan and saying, "man I wish it would rain, snow, or mud slide, so I can take my 300C AWD sedan out and race people!"

We can't compare AWD performance cars (oranges) and AWD family sedans (apples) and be serious. ;) Just my own opinion.

Well speaking from the experience of having both cars, I would have to say the the AWD does take off much faster but tends to slow down after reaching higher speeds. The RWD that I had seemed as if once the tire found grip that there was no slowing it down. Both feel about the same when already going 50 mph and stomping the pedal to the floor. Tough call but I'd rather have the grip if I have to do a sudden swerve or turn. Just my two cents.

Not only is AWD heavier but there is more parasitic horse power loss in the drivetrain. AWD has a distinct advantage in launching the car. In drag racing, the rule of thumb is that a tenth saved on the launch is worth two tenths in the overall ET. Is that enough to make up for the weight disadvantage and the power loss? I don't know. Time will tell. However, I'll take AWD for carving up a mountain road everytime.

Added weight from the AWD doesn’t help either.

There is a big difference in the Audi AWD Setup for that Euro Race circuit. Comparing those AWD Audi's to the everyday soccor mom 4-Matic system is like comparing my V8 to the one John Force uses. Yes, I do in fact use Nitro-methane in my Hemi. :D :D :D

These figures may help:
140lbs weight difference (advantage - RWD)
drag/driveline loss (advantage - RWD)
3.07 vs. 2.82 gears (advantage - AWD)
traction (advantage - AWD)
wheel weight (advantage - ???)

Looks to me as though they should be within a tick-or-two down a 1/4 mile strip. Hell, the amount and octane of the fuel in tank as well as the drivers luggage and personal weight play equally important roles, too.

Hope this helps.

Well cant wait till spring(run 1/4 mile) and i will be driving to chicago this weekend. I am trying to get a good quarter mile on my car. I clocked it on the street with a approximate stopwatch got around 6.3 secs. I would say fast enough but i know my timing was off at the start and at the end too late both times. Maybe could have saved .3 secs but i would like to know if there is any device u can get to clock these things, they used to sell these things u can put on the dash like a radar(i use a cobra ofcourse) that calculate ur quarter plus your 0-60. Let me know if some one seen something like this.

HOW YALL LIKE MY SIGNATURE PLEASE READ IT LET ME KNOW TOURERS AND LIMITERS ARE GONNA BE PISSED.

How come we are'nt mentioning the dirty little secret of the AWD's higher center of gravity offsetting it's claimed handling benefits? Until we see the AWD beat the RWD on a road course, it is very presumptuous and wishful to say the AWD handles better despite the biased seat of the pants "feel" on a test drive on a public road. Let's see the #s, lane change, slalom, road course, skidpad, (valid only if on the same tires). Audi's Quattro is clearly superior to thier FWD, in the BTCC the Quattro was banned from competition even after a weight penalty.

300CAWD, I think maybe that 6.3 second time would be a 0-60 run, not a 1/4 run.. Our cars are in the low 14s and some people have said they've gotten high 13s out of them. Our 0-60 time have ranged from 5.3-6.3 so there's plenty of play in there for how, who, where, temp, road condition, etc.....

If you ran a 6.3 quarter though...... Then as E55 KEV was talking about, maybe you have a nitromethane Hemi as well..... =)

Maybe Slower

In my experience, AWD will be a little slower depending on the driver, the track, how the car is set up, mods etc.

You have two sets of diff gears to mobilize and in theory evry additional gear tooth or gear added to the train takes energy (darn that sounded good!).

The main aspect of AWD will be traction and skid pad performance. If you thought you could stand on the pedal with the electronic help of the standard 300 C wait till you run the AWD. As long as the pavement is dry there ain't no corner going into or out of the rest of us will be able to stay with you.

I think any of the 300 C's would be a blast in autocross.

My $.02.
