And you're right, both of these cars are slow...slower than just about anything anyone has tried to make fast, including the friggin' Corolla Sport. But then, who's driving the Corolla Sport and who's driving the Benz?

Not trying to be rude here but the cars has the same shift poits. There is no "optimized for the 6-speed" -- it still runs a 3.46 rear-end.

No no no....the fastest c240 is an auto, that's all they offer...it's poorly geared, same as the auto c230...but they offer a stick for the 230, which every damn publication on earth is quoted as saying Mercedes has lowered the ratio for first gear for quicker acceleration off the line in addition to shortening the spacing between all other gears, while adding an overdrive sixth gear for quiet, low-rev highway cruising for fuel economy...
Clearly, the gearing is different, and the 5-speed auto in these cars is bush league. So, after all is said and done, the C240 is poorly geared

WHile this is fun to debate, I must reiterate that it's irrelevant. The C230 is a much sexier car regardless...

Dragging out 1st and 2nd enough to reach 60 in 2 gears would likely have shaved as much as a half second off the 0-60 times, just by avoiding that shift into third at 53mph. A half second doesn't sound like much, but consider that published times for the C320 and C230-M111 are as low as 6.8 and 7.1 with the current manual. Neither time is really fast by todays standards. But, 6.3 and 6.6 to sixty are definately much more competive times.
Don't misunderstand, I despise the automatic-all automatics for that matter- but the manual isn't as well sorted as it should be. It makes hay on the auto by virtue of its additional gear, and more effecient operation(less driveline loss).

I'm a M111 owner myself, so I don't always pay attention to the M271 threads. But I do remember a thread about this problem here, and at MBKlasse.

Another great example was the C32 at Virginia International Raceway. All weekend, once we got to the straight, he'd be long gone, but then in the turns, I would catch him either by the end of the braking zone or the exit of the turn (or complex of turns). The C32 was "soberingly fast" on the straights though.

Thats not really the problem. The problem is that manufactures are tring to idiotproof the cars and stagger the gas and brake pedal. Its a good inch and a half difference between the two, then they are also seperated by a decent amount. I stopped wearing my driving shoes and use my Etnies for driving 'cause the wide sole helps alot more in this car. I tried to adjust the gas pedal a little higher but could do it. I wonder if the parts department has a spare pedal assembly I could borrow to make a riser?!

A good example is a Miata at CMP. The guy had R compound tires and good camber, but close to 50 or more less HP. He was able to carry enough speed out of the turns I didn't gain on him on the straights. I really had to hit EVERY turn PERFECT to catch him.

Lets say you are making 250HP in your car. Pretty good estimate, pullied, engine well broken in, lightweight flywheel, exhaust, etc. The C32 is probably only slightly heavier, but has nearly a full 100HP on you. No surprise he sprints for the exit after each turn.
