" Some interesting information was posted in the N20 section of the BimmerBoost BMW forums regarding the durability of the N20 motor. Now, the motor is becoming very popular and is winning multiple awards and rightfully so as it is currently the best factory 2.0 liter turbo four cylinder in production. The keyword there being factory as apparently it is not going to be a stout aftermarket tuning platform at least not yet. Take the information you are about to read as unconfirmed but from an interesting source.

There are companies that stress test engines for OEM's. One of these companies has been testing the N20 apparently. The advice given is not to go beyond Stage 2 on the N20 which means a slightly more aggressive tune on the factory turbocharger. Why? The N20 head apparently cracks at around 331 pound-feet of torque. That is not exactly a whole lot of torque in the turbo tuning game especially considering the motor puts out an underrated 258 pound-feet from the factory.

Apparently the engine is just running very hot and multiple heat cycles are creating problems. BMW behind the scenes is supposedly trying to correct the issue. For whatever reason BMW seems to have a reputation for problems with new motors. S54 bearings, S65 bearings, and the next BMW new motor issue looks to be the N20 head cracking.

The story is that one of the lead designers and engineers for the N20 was flown out to the USA to inspect the findings for himself. It is doubtful BMW would do that unless there was something of substance to this. This same company also apparently tested other BMW motors including turbo motors such as the N54 and N55 when they were new and they did not run into these head issues.

So what is going to happen? Well, right now it is not recommended for N20 owners to push their motors too far which they can't anyway as there are not aftermarket turbo options out just yet. BMW will likely resolve the problem with a new head which will mean for those with the N20 there will either be a recall or there will be a BMW part number option to get the new head. We will have to wait and see what happens but N20 owners should be aware of the potential issue especially if intending to tune as BMW is unlikely to say anything until they have to. "

" There is a power war going on and now it seems we have a weight loss war to add to the mix. Mercedes already showed it intends to save weight with the debut of the new R231 SL-Class which had the goal of shaving 300 pounds off the curb weight. Mercedes-Benz came very close shaving 242 pounds from the car officially which is a healthy drop. This leads one to believe that Mercedes can meet their ambitious goal of 220 pounds or at least close to it off the W205 C-Class for 2014.

This would mean the C350 would drop into the 3400 pound curb weight range. That is pretty light for a C-Class and would make it lighter than the 3545 pound curb weight BMW quotes for the F30 335i. If Mercedes gets lighter in this segment that certainly makes the next generation C63 AMG versus M3 battle very interesting as the C63 likely won't suffer from the same large weight penalty it did in the W204 versus E90 generation battle. We will know more after the official debut later this year but it is nice to see manufacturers doing more than just upping power and torque.

" Possibly but it opens up a can of worms as edits provide no notification. So what do I do if you upload in a bunch of porn after an edit? You see the problem?

I can just add it in for you. Added.

" @TT C6 edited your post to show you what I mean. "

" Not too much but it will be lighter. "

" Thank you! "

" The new C63 won't get the M157 it will get a 4.0 liter turbo motor instead. "

" Definitely true and in high wind conditions. "

" Does it need to be super heavy to tow well? "

" I see what you mean about not wanting to go to the dealer.

" I was more talking about the difference between the RB's and the Stage II's how big of a variance are people expecting? "

" The Porsche Macan should make its debut relatively soon likely later this year at the Frankfurt Auto Show. Some details have leaked out although they can not be confirmed. The interior spy photo clearly shows design elements from the Panamera and new 991 generation 911. The center console also shows a PDK style shift lever so the entry level SUV will have a dual clutch transmission. Lack of a traditional automatic will likely affect tow capacity.


A six speed manual though might be available although it can not be confirmed. A manual Macan Turbo sure sounds like a lot of fun to drive. So what are the engine choices? How about six of them:

Diesels:
• 2.0 TDI 4-cyl, 187bhp/258lb ft
• 3.0 TDI V6, 261bhp/369lb ft "
