Read the original post - that was the point. I was answering questions that people asked in response and updating on the trip. I left after I posted.

 

That's interesting...I followed up since I'm still part of bimmerforums.com and found this

Ever since my 328, I thought that they had resolved these type of issues by now. I guess not..

 

Wow. That sucks...
---------------------------------
Got to tear up the new BMW 335i twin turbos yesterday at Autobahn. We had a group out there that PDI instructed and I did the lead/follows session with my group.

First, the good:

The car displays virtually no turbo lag. The acceleration feels on par with Janica's S4, it's extremely balanced on the track (I could not induce oversteer pushing them to about 8/10ths) and the stock brakes showed no fade whatsoever after a pretty hard 30 minute session. I must say, I was quite impressed. I was hitting 115 on the front straight of the north track. On top of all this, they have run flats on the car! Yes, run flats. With race rubber this car would rock! Very nice car. The backseat room is quite a bit larger than the previous model and of course the interior amenities are excellent.

Now, the bad news:

Each and every car overheated and shut down. Hmmmm, how's that? Yup! The oil temperature on every car shot to 300 degrees and the cars shut down. We learned that early on and instructed every driver to watch it closely. Driving amounted to about 5 hot laps, 2 parade laps, and so on. Never saw anything like it yet. Talk about a fatal flaw on these vehicles. Can't wait to see this happen to the general public and see how BMW responds. I guarantee you we were not pushing these so hard that no one will ever experience what we did. In fact, one of the ABCC members took a car home with him and on his ride in to the track, aggressively I might add, overheated it and shut down on him.

Every car has an achille's heal. I guess this is it.

 

That is the reason why I stay away from 335i and went with the G instead. I guess I don't like overheating cars.

 

Yeah - and Edmunds also had the problem when they pitted the G37 against the 335...

It happens on lap 4. That's when the difference between Infiniti's 2008 G37 Coupe and BMW's 2007 335i Coupe crystallizes.

All at once the BMW coupe that we've considered the leader in its class finally decides it's had enough. With its oil temperature pinned at 300 degrees F and its coolant temperature climbing rapidly, the turbocharged Bavarian wonder engages its limp-home mode and we crawl pathetically back to the pits.

This all-too-dramatic demonstration of Japanese-versus-German engineering occurred at Nissan's Arizona Test Center, where Infiniti invited a select group of journalists to drive the 2008 Infiniti G37 Coupe back-to-back with Germany's best. The limp-home part, well, that wasn't part of the plan.

In fairness, both cars had experienced a relentless pounding by journalists with a profound absence of mechanical sympathy before the BMW finally succumbed to the desert heat. But the flogging had been similarly abusive to both cars, and the Infiniti G37 never showed any signs of weakness.

 

Kinda scary having overheating issues on car of that price with that kind of performance, that many will surely want to take advantage of from time to time
