How to make c300 go faster?
I love California and its weather.

As for the OP's concerns, as others have already sufficiently noted, if you want a "fast" car with AWD, this is not the car. The AWD system components will add more weight to the C300, further decreasing its acceleration/deceleration performance.
Having said all that though, I gotta admit I was pretty upset to find that C350 won't be offered with a manual transmission, as that is a must-have option for me. I wanted the extra HP. But the 300 has surprised me after the purchase with its performance. It is true, however, that the car "feels" faster than it really is... maybe it's the gearing, maybe it's the... eh... something.
The objective 0-60 MPH or 30-90 MPH numbers aren't too impressive, admittedly, but for me, it is not too big of a concern -- I stopped caring about those numbers at around age 25. By then, I had accumulated 8 speeding tickets, 2 accidents (both my fault, technically, despite the other party's speeding), $7,000/year insurance, and a license suspension with the threat of revocation. I even had a spin-out on a two lane mountain road while traveling at 80+ MPH and nearly fell off a cliff. Since then, I've learned to reprogram my STUPID STUPID STUPID brain, and enjoy a $1200/year insurance and no tickets for the past 5 years. 
Two days ago, I tried a WOT run for the first time on a deserted and nicely paved stretch of road near my house. I was not impressed. But others are impressed with me when they see me in the car, so that kinda makes up for the performance... I guess.
ECS tuning has a 1.8t GTI w/ 400hp. Daily driver too. My Passat was capable of that as well. I never took it there. I had the APR flash and a Neuspeed exhaust. It was roughly 230hp, 255tq with the stock K03 turbo. Not huge, but the car is totally different when in chipped mode (I can switch between programs). My brother had a 300 hp GTI. Gotta love VAG turbo cars. They surprise everyone!
I have the 6 spd manual C300 and it's no slouch. I have always been more a fan of good handling than 0-60 times since my old Chevelle project. I used to get into a lot trouble with it.
The best chance we will have, as I and others have indicated in the past, is forced induction. Someone will do it. Who knows, maybe it will be one of us. PES tuning made a great supercharger kit for V6 Passats and A4s. Something like that would be great.
The top speed of a U.S. spec C300 is gov limited at 130, or at least the test car Car and Driver was given was limited to 130. I highly doubt they would give them a car gov less than what production cars are seeing how its a test to see which cars are the best/fastest.
I feel your pain with the slowness of the 4matic C300. I see the guys that think its fast already posted so take it for what its worth, for some its enough for others like myself its just adequate. It wouldn't hurt them to add 10 to 15 more hp or give it a nice torque boost. Its really a double edge sword though, as even if the C350 were offered here in the states with 4matic I wouldn't have chosen it due to the fact the base price would have been way too high for this car. I struggled with paying $38k for the car, better cars could be had when your pushing the $45k mark.
Food for thought: C300 Manual 0-60 = 6.5 seconds...very nice. C300 Auto 0-60 = 7.1...not bad for this class. C300 Auto 4matic 0-60 = 8.1...ok this is not very good at all. Benz has a great starting point, but they need to figure out a way to make that auto trans and 4matic system lighter. Before everyone jumps in and says "yeah but 0-60 times dont really mean anything" let me point out that for 90% of C class buyers 0-60 is the only real performance number that matters. For most of us all the action are cars see is from stop light to stop light.
Thought I might add for a laugh..if power is what you want from a C class..theres always the Brabus Bullit Black Arrow...shoe horned a twin turbo V12 into a C class and murdered it out. I don't dare say the price, but you could have a Lambo for the same scratch ha ha.

Exactly. That doesn't suck. I have said it before...fast is good, but for me, driving a car that handles well and performs on the highway is more satisfying. Maybe off point, but I've seen too many people, racers and innocent bystanders, get hurt by stoplight drag racers.
And, not that it applies here, but Viagra dragsters are just ridiculous.

Yes true there, if your going to race do it on a track and not on public roadways. I was just making a general statement as the only thing I need my hp for is merging onto interstate around here. I always feel like its a crap shoot in the C300 on if I will merge safely or have to cross my fingers and hope she goes ha ha.

Interesting. I like it. Maybe it's the automatic transmission. When I tested the 300 and 350 with the auto, I was not that impressed. The manual seems to liven things up a bit. I've noticed torqueband is broad in this car, almost like a turbo charged car (which is what I am used to). I think that is why I am impressed with the car in general.
The Mb interactive site gives 7.3 sec for the stick shift, 7.2 for the auto, and 7.3 for the 4matic! I think people sometimes confuse the noise and drama of stickshifting as being faster than a smooth quiet auto.
"MB is conservative with their numbers, they usually won't even post them in print."
C,mon. MB post them all over the place. In my brochure, handbook and the Canadian and European websites.
Okay, that's just a joke - but a also an apt metaphor for what I'm trying to avoid inthe c300. If I'm going to get a nice ride, I'd like it to be nice throughout. Empty suits are, well, empty suits whether they be in business or on the road. The C-Class makes a statement, I'd damn sure like to be able to back-up that statement. The c350 is all I need and agree it is a damn fine car, but the c300 (the car I'm asking about) doesn't cut it, and that's the only way to get 4matic, so was hoping there would exist go-fast bits which could help it be the car it needs to be. Unfortunately, I guess I'm coming to the realization that perhaps the c-class isn't right for me right now since I need AWD and won't settle for "almost quick". And no, I'm not looking for stoplight races on a Saturday night, or other showmanship. But, I don't want to be embarassed. And you get embarassed when you make a statement, have a beyond-visual-reproach ride and then get smacked by the same corolla you laughed at when parked. I dunno, maybe until the 4matic is available in c350 trim it just won't be ready for prime-time, imho. Or, I just have to satisfy myself that I look good and am safe but other people will be sleeping with my wife, metaphorically of course.

On another note in reference with the original question, I did some research (Road and Track testing scores) and as it turns out the S550 and C350 put up near identical 0-60 times.
Some people are supprised when I tell them it is a $40k car (i drive the c350); most poeple think it is a +$70k car (I guess they confuse it for an S class).
Yes you can buy a faster car for the price, but I doubt you will find more style!!
Ironically. I have driven Audis from 2000 – 2006. 2000 1.8T B5 APR chipped and 2003 1.8T B6. Great cars, but I don’tthink they are next to a C class (and it’s not just about the image here). And by the way, BOTH Audis blew the turbo at one point (and the B6 was never modded), so I would have an extra $1000 under the pillow cause it will happen.
I myself would like to see the c350 with 300 hp (like many of the others 3.5L engines out there), but then I look at the whole package and I know I have a great car.
So if all this is not enough for you, and you still need to make 0-60 in 5 secs, then this is definitely NOT the car for you. Get a Lexus IS350 which is 5.4 secs and it’s about the same as the C350 (if you don’t mind trading the German Engineer). Or sink another $8ks and get the 335.
P.S. 777, I don’t know why you had to bring wives into this, but I’m not going to ask (bad experiences?)
