For those of us that lease for only a few years before changing it up, spending $$$ on mods is like setting $$$ on fire.

Can't wait to see what they're capable of producing with full bolt ons and tune.

The thing is...yeah have all the HP you want, if you don't have torque it doesn't mean anything.

If you're going to put headers and a tune on a C63 then put downpipes and a tune on the m3.
Give credit where credit is deserved. Mod for mod the m3 is going to be faster than the c63. However, it will sound like straight up poopy doing so.
C63 loud and in your face. M3 farting along.
HOWEVER, bmw is winning in the style department now. The w204 is far better look than any rendering of the w205 that I've seen.

Ha, anyway, just saying that people shouldn't compare modified cars to unmodified cars. Obviously you can, but it isn't necessarily a fair fight.
Also, the fastest car on the road debate is just too open ended. I completely agree though, everyone has their own taste.
I was just simply stating that a w204 c63 w/ headers and a tune vs a stock m3 isn't a fair fight and even then I don't think the c63 would walk all over the new M. Might win, but not by bus lengths depending on the distance.
I think the new m3/m4 have lost soul compared to it's predessesor. Sure, it's making the power now finally. But, as they said while, they tested it against the 507. That something is just lacking there of from the bmw. It wasn't as much of a drivers car as the c63. Sure, the c63 is dated but it had something that had captured many enthusiasts... And that's because it was built with soul. Sad to say I feel as if many upcoming cars will never be the same... Sure they will make more power but power isn't everything. At, the end of the day everyone is in what they perceive is "drivers" car.

Now modified cars he ran the m4 on his piggyback tune with E25 fuel which he said would put him around 490 wheel STD(big octane boost) and trapped 124 again very good. My c63 coupe with headers row air box and tune touched 125 on vbox through the quarter mile in 60 degree temps. So very similar numbers and other have hit 124+ on vbox and strip with just headers + tune. Def won't win by bus lengths and it will be one hell of a race but the old w204 is still doing OK
And sure, power isn't everything. But there is some serious technology in newer cars. The N/A world is fun indeed. I had the C63 and I still have my RS4. But this new bi/twin turbo tech in larger displacement engines are just going banana's on only a tune.
As for N/A vs FI not being a fair fight... why not? Both are stock.
Right now the "new'' sedans leading the way are the m5/rs7/e63s. If you have the money those are the cars people have been grabbing up. Again, I have absolutely no hate for the C63. I'm actually heavily considering buying another one to replace my RS4. I just haven't quite made up my mind on how much I want to spend.
On a side note, bms is awesome. Jb4 + downpipes in my 1 series and I had 1 hell of a car for the money.

N/A vs FI is a fair fight and for outright power there is NO doubt FI will always win in the end. For me i also enjoy the ripping sound and feel of a great N/A engine puts a smile on my face. That said I have a c7 z06 on order that is FI and will stomp on both of these cars. If your just after outright speed there is much better cars than the m4 or c63

did some guy in the background yell..."it sounds like my prius"... lolIm sure its a wonderful car... , I mean I had three BMW's prior...330/ M3 x2... but seriously... it sounds like rice burner...
No wsy would BMW under rate the car by 60 HP / 25 lb ft
Why? Marketing is all about the numbers these days
With those numbers and low weight should run 11.5/120+
We'll see

70k for the m4
Used c63 plus the balance in mods
C63 will suck its windows out

The New M3/4 will be a quick car. The weight reduction + considerable more tq down low in the power band will have many thrilled with the perception of a faster M car. When in reality they are simply catching up to competition. I love the new design, and Im sure it will look stellar on the road.
However, if you do mod the C63, it really has no chance. Lets see what the tuners have in stock with the new M's.
I figured, Flash tune / headers / exhaust / intake / larger turbo + piping etc. Good for 600ish wheel HP on the M. Thats stage 2 territory for us.
O-100km/h 4.2 sec
0-160kmh 8.8 sec
0-200kmh 13.7 sec
DCT, ceramic brakes
Lets find the same for the 2007 non PP C63
4.6
9.6
14.6
Does that difference sound like a 600 lb lighter car with more HP?
So a 7 year newer design is < 1 sec faster to 124 mph

Did the design team hear that and say "Damn! That's exactly how I want my flagship car to sound!"
And that dude that screamed "Sounds like my prius" cracked me the **** up
But besides that, I am quite jealous. Us AMG owners hold the bragging rights to power and torque, but with bimmers like this on the road, I might have to think twice before I slam my foot down.

And the guy trolling the sound was hilarious!
