hard driving, burning smell..?

psychoactive · 05-08-2007, 04:39 AM

I was going between 100 and 140mph for like 5 minutes and I smelled a weird burning smell in the air coming in from the air vents... by the time I got home the smell was gone, did I burn something?

I've smelled the same thing, and in fact, it is more prominant in the trunk. Only happens after really driving the car hard. I assumed it was the brakes, but I really don't know.

I hope it is not burning rat poopoo in the vents.

Well I couldn't smell anything from under the hood when I was outside the car :-?

It is a race car though, it is made to be driven hard! She'll be fine.

It was fun speeding around with a riced out civic, a saleen mustang and a cbr... =)

is your car manual?

it's probably your clutch then -- whether or not you were rev-matching a lot...

it might just be your brakes... stopping from anywhere between 100-140 frequently puts tremendous strain on your brakes...

hope your broke in your car properly first

yeeh. i observed the same thing. after i drive it hard, i notice burning smell in my garage. it always happens, even when i drive only up to 5000 rpm and no more. wat do u reckon happens?

caesardog217 · 05-11-2007, 11:41 AM

Same here, my car is step, so I guess its in manuals and autos. The smell isnt that strong thou, I had her up to 140 yesterday and the smell was faint.

Andrew9931 · 05-26-2007, 02:16 AM

break in.. u cant tell me ur 2007 is completely broken in yet..

normtrum · 05-26-2007, 11:53 AM

I remember somebody posted the exact reason why this happens, I tried to look for the thread but couldn't find it. I do remember many people saying that it's perfectly normal, and nothing to worry about.

ksfrogman · 05-26-2007, 12:26 PM

Yeah, likely brakes, maybe clutch. New exhausts sometimes have a smell to them as well.

calvino · 05-26-2007, 12:48 PM

I go 100 all the time and I don't smell anything

is probably the brakes

it's been 2007 for almost 6 months man, there's probably a few people on here with 15K miles on 2007's

thealbert · 05-27-2007, 04:23 AM

Its most likely your brakes or clutch. Those are normal after a hard drive.

I get that too after a hard drive or even when the weather outside is past 100 degrees F and I go for a fairly spirited drive.

I was about to suggest this as a possibility as well. - Exhausts when subject to higher temperatures can begin to smell a little burnt. Happens to most cars...i believe its the cat converter putting off a funny odor. Nothing to worry about...normal for this to occur.

Its not a race car...but it is built to handle high speed driving, BMW knew what they were doing...its all quite normal.

E90Boy · 05-27-2007, 08:59 AM

I have the same thing and when I take it in the stealership replaced my air blower.

E90Fleet · 05-27-2007, 03:40 PM

If the car is pretty new, it could just be the part id stickers from the factory burning off.

You may also just have driven through a bit of smoke without knowing it, and sucked it into the aircon

ERSTD · 03-19-2012, 12:06 AM

Bump, i have same problem - 60k with AT trans... air blower? Coolan leak? brakes? Power steerin fluid leak?-what could be burning. Doesn't happend all the tine and hard to pint point

Thanks in advance!!

e90pilot · 03-19-2012, 08:48 PM

This might be a different issue since this thread is 5 years old. It's probably oil. You might have small seep and when you drive hard it burns.
