The trail left behind was a prefect outline of the undercarriage as it leveled the snow. Had I been trying to scale a 2' pile of gravel, I would not have attempted the same maneuver. Considering the fun I have driving the 328xi, ad especially the 335xi with the twin turbos and the AWD, as long as I'm in New England, I will consider other vehicles when my car goes geriatric, but I doubt I'll buy any other marque. This is just too much fun. xeye

Replying to: investor27 (Jan 12, 2009 9:39 am) I cannot for the life of me figure out why that might be. I used to live in Chicago and owned two turbo cars while I lived there. The only issue (if you can call it that) with cold weather that I ever found was that you were able to get significantly MORE power from the engine on very cold days, especially if the intake was intercooled (which the 335i is).

Replying to: shipo (Jan 12, 2009 10:22 am) I, for one, do not think it is a good idea to block the front air-intake. It is my understanding as well that colder air increases performance by increasing the horse power. And I believe that turbos and twin-turbos run a lot hotter than normal aspirated cars and will need the front air-intakes to cool them down. I'll try to find the pictures of their projects and post them here.

Replying to: investor27 (Jan 12, 2009 11:47 am) 1) Many things that may be true for the TDI generally have zero bearing on other cars, turbocharged or not. 2) Colder air allows for increased performance due to the fact that the colder the charge, the denser it is (i.e. more oxygen molecules per given volume, allowing for a commensurate increase in the amount of fuel injected into it -- this is more of a factor with normally aspirated engines), AND the cooler the intake charge, the high the boost can be and/or the further advanced the ignition and valve timing can be before reaching the point of insipient detonation.

Replying to: investor27 (Jan 12, 2009 9:39 am) On the other hand, Green Bay is a place where only truly die-hard Packer cheese-heads live! I don't have any doubt at all that the 335xi will perform very well in the cold. I do suggest following BMW's recommendation about top tier gas (Shell, Sunoco, etc. Your dealer can give you a list). Also, check out the right oil. I use Castrol Synthetic 5W-30. That should work for you but check with a knowledgeable mechanic. I used to think everyone should drive a 335xi, but if that were true, I wouldn't be able to blow by other cars so easily! Go for it. I'm sure you won't regret it. I would strongly suggest a block heater, though. I used one for many years in Montreal, and it was an engine saver. xeye
