Ok, then that just proves another point, on how the c32 engine deals with a lot more stress, according to you, but somehow c32 engines don't seem to be blowing up everywhere, weird...

 

Simply put:

BMW engines are OVER-STRESSED and fatigue.:o

MB engines are under-stressed and have plenty of reserves for effortless performance.

 

FI and NA put stress in different places. a higher-revving engine, like the M engines, will place more stress on the connecting rods. a FI engine will place more stress on the heads. it all amounts to if you over-do it, the engine will break in different places. of course being that we're talking about MB and BMW here, i dont think they're going to skimp on cylinder liners, heads, or connecting rods. it costs them less in the long-run to make sure they're durable. i agree with TeKNiC330, the engine failures were more than likely a design defect or possibly some error in the metallurgy.

 

I'm sorry, but BMW currently makes some of the smoothest engines around.

 

The 996 Porsche had failures in some of their stick trannies last year - before 500 miles - and because of the catastrophic failures, the entire tranny had to be replaced!!

Diagnosis:

Improper or lack of annealing of component part(s)!

 

As far as engine drive, i think BMW's have a much more aggressive and linear feel, the build quality possibly better than the mercedes.. for the 9 years i had my bmw. i had TONS of problems, but none related to the actual engine..

mercedes. the engine is much more smooth and humble.. it makes u know you're going fast, but it doesn't slap u in the face and tell you...

personal preferance for both.. i like to drive aggresive so i like the BMW engine.. i can't pass judgement on the benz engine as i've only had it for 4 years...
no problems yet tho *knock on wood*

sorry if someone has already posted something like this.. i tried to read through the whole thread but a lot of it was arguing

 

BMW stands for "Beginner Mercedes Wannabee's"

Oh, and drive a 2003 S600 with a Renntech chip and do a 0-60 in 3.1 seconds and tell me BMW is making the best engines......

 

you know, as fast as the new 600 is, and as much as i love the twin turbo 12, you're gonna have a really hard time convincing me, even with the chip, that the car can run 0-60 in 3.1s. 3.8, 3.9, sure, but not 3.1.

 

LOL! A "MODDED" Mercedes-Benz engine vs. a "STOCK" BMW engine?

Have you forgotten about the modded BMW M5 that SMOKED the Mercedes-Benz SL55 AMG and a Lamborghini Diablo?? Go to the "Kills" forum and search for the video.

And secondly, the BEST engine is not always the MOST POWERFUL engine! LOL.

The BEST engine has the best combination of power, responsiveness, and overall feel.

 

Serious omission errors:

What about oil burning?

Gas guzzling?

Longevity?

 

Please go to S220 section and look at dragstrip videos by Ben Treynor......where he was running 3.1 and low 11's in the 1/4

Also read page 40 of this Octobers Car and Driver which features Treynors 2003 S600 and showed 4 sec 0-60's on regular roads with all season tires.

BTW, the RennTech chip used in the S600 is simply bringing the engine back to Maybach specs.......which is still a warranted engine by Merc., it's not considered modified since Merc. detuned it when putting it into the S600.

 

very sweet, but i guess i should've specified street tires. the 4 seconds is what i expect on the street. slicks definitely give that car better traction, and definitely better times at the track. but i think in terms of day-to-day driving, the 4 second figure is more pertinent. but still, very nice time.

 

Bad case, you want smooth? You get a Lexus.

Tell me this thing real quick. How many M5's do you see, quite a few, now how many are modded, quite a few once agian. Now how many of those are under complete warrenty, have laps and laps of luxury and can double as a limo to the next party. Oh yeah, you can also drink your coffee and not spill it. Most BMW's are built with the mindset of a boy racer in mind. That of course my opinion, you cannot change that. It isn't a bad thing either!

 

i agree. that 3 liter 6 in the avalon is really smooth. as is the 4.3 liter 8. i like the 4.2 liter 8 in my mom's '97 e420 as well. it's too bad it doesnt really get that nice v-8 burble til you start passing 3000rpm. too quiet til then.

 

I look at the 3.1 0-60 a little differently. Grudge matches at a NHRA sanctioned dragstrips is where you should "race" your car......especially autos in this "beyond what not too long ago used to be supercar performance". Street racing kills innocent people.

3.1 is a 3.1....any other car grudging you can put on the slicks also.

 

i agree it should be at a track. i wasn't referring to street-racing. to me, those numbers give me a good indicator of what's possible when, say you're getting on a freeway, that's moving at full speed, but the car in front of you is going 30mph on the freeway. that's a dangerous situation to be in. or some of those pesky on-ramps that are 90 degree turns that dump you right on the freeway, with minimal time to get up and go. but 3.1 and 4 seconds is a huge difference when in these situations.

 

Huge difference on ramps between 3.1 and 4.0? At 4 seconds from a standstill or 30-70mph on a standard merge (and the S600 is quicker in this realm given its torque).....it would have to be an interstate completely full of modified Vipers and GT3 Porsches to make any difference

 

half a second at 60mph is 44 feet, or about three car lengths. seven tenths is another car length. to me, that's a big difference, especially the way people drive here. the more space i have the better. likewise, the quicker i can get upto speed, the more cushion i have between me and the other car.
