G80 M3 Comp XDrive

[Dave2013M3]

No. G80 m3's have an insanely good launch control.

My KB s550 went against a G80 m3 comp. Pretty even Stevens. Both on dig and 50mph to 155mph. Mind you it's on a carb approved tune so plenty of potential on the table but the A10 isn't making up the difference.

xDrive is worse on the top end than a rwd m3 due to extra weight and drive train losses.

There is a guy on the Bimmerforums with a G87 that is running 9.80s at 138mph with just an unlocked ECU, DPs and some weight reduction and on a drag radial.

R44 converted one M2 to AWD and it runs in the mid 8s!!!

Basically what a A10 stage 2 Whipple (or other supercharger kit) car will do

If there is a policeman around the area you hit 130 mph, you both may end up in jail at about the same time

Please stop...my 2020 Mustang GT within the first year was in the shop having its plastic oil pan replaced not once but twice. Not to mention the 3 recalls that the car had and the bad 02 sensors. Also, BMW M cars are very stout. The S58 engine is a beast and is very robust.

The reputation of BMWs being unreliable didn’t appear out of random thin air. German cars are unreliable, it’s part of their business model to make money off of service and overpriced parts.

It’s like Mustangs or American cars having a reputation of using cheap materials. There’s truth to it.

German cars are unreliable

I've never had so many quality problems on a such young vehicle (now 5 years old at 25,000 mls) as on my Mustang...

That makes at least two of us ...

Maybe BMWs, but the two VWs I've owned were flawless in terms of reliability.

I wish I could. I plan on getting a stage 2 Whipple and a few support mods to make around 800whp in the future but that's the only problem. Being in college, it wouldn't be financially responsible to drop 10k into a Whipple for a car.

It may be a far future plan, but I think you're on the right track...

Still doesn’t refute my comment. It is by design. German cars are made with new tech, and new tech fails, until improved. This is how they make money as well.

What I've heard about German cars, from engineers who've owned them, is that the VW Audi Group has got the lifespan of their parts calculated down to a gnat's ass.
When they say to replace something at 60,000 miles, they're not kidding: It's made to last 100,000km and no farther.

BMW might be more fast and loose as to what is a wear item and how long it'll last. That E92 M3 sounded great until I read that the rod bearings are a wear item.

I've only ever had German brand vehicles (except BMW), I've never known anything like this before...
Maybe this refutes your comment?

But I don't think it's a question of the brand or the manufacturer, but of which manager knows better than the engineers, who would prefer to build the best without even having to listen to the accounting people.
It is possible that the engineers at BMW are not currently asserting themselves as one would expect.
The basic problem with everything is shareholder value. It is no longer about having the best product, but about being the best on the capital market. Having an acceptable product is only a means to an end.

A cocky rich kid at my university shows up with his daddys m3 comp xdrive once a week or so acting like its his and talks trash to every guy he sees about how "his car" is faster and better than everyone else's. He started talking trash on my 19 gt a10 with an intake, catless headers, catback, e85, and 305 ps4s about how its slow and "his" m3 is better and faster. Im wondering if around 475whp is enough to beat a fully stock m3 comp xdrive in a 60-130 for educational purposes.

Ahh...no he will d

Less than 1% of E9X S65 motors are affected by the Rod Bearings. My own E2 M3 which I sold had the rod bearings done at 60k miles and they were fine. The good news is that the aftermarket fixed this with better a better bearing design and the rod bearings can be done for around $2k. It was a high revving powerplant, even higher than the GT350. The GT350 has had its share of failures as well. I agree though, having the rod bearings as a wear item is a little concerning. The issue is you don't know if yours are failing or not until they fail or you replace them. The S65 engine was a marvel.

I own a 2011 e90 m3. The rod bearing issue has been blown out of proportion. They updated the rod bearings part way through I believe. Most people have had them done as a precaution. Much like the oil coolers in UK.

Remember the whoo haaa around the oil pump gears on the coyote?

Not going to lie, BMW don't know how to make a gasket last. Terrible for oil leaks

Not really. From experience, I’ve had a MB in my garage before (from an ex-gf) and that German trash can always had issues. Electrical issues out of nowhere, and a major trans issue. The brother had an Audi, which sat in the drive for a few weeks with some trans issue as well. From personal experience, German cars are unreliable. And the reputation of unreliability is not in vain. In contrast, Japanese cars have a reputation of reliability. Again…and with good reason.

@JudSam How well have these cars been looked after and maintained? How old were they with what mileage.
