Modern diesels do not smell. I had an Audi Q2 30 TDI for a weekend - didn't smell when the engine was cold. Left the engine idling during photos I took of it to keep the instruments on - no smell.

I dunno, it depends on how stringent your definition of "modern" is, but in France there are plenty of new-ish (5yo) diesels which leave a lingering diesel smell when they drive by.

I hate the smell of diesel on my hands when I fill the car up, too. Blechhh

Yep, now that I've been riding my new bike near/in more traffic, modern diesel passenger vehicles absolutely do smell.

Yeah, 'cause now they have to dump deer piss in the exhaust. :lol:

Diesel fuel itself is smelly, and the smell lingers far longer than gasoline because diesel doesn't evaporate as readily as gasoline.

You can get diesel that no longer smells, however these are around 8 cents per liter more expensive.

For what it's worth I love the way diesel exhaust smells. If I could let an engine run in my garage without any ill side effects, I would do it.

Cummins Rams are the worst by far. You can really feel the fly ash get into your lungs, and they're often modded to be ridiculously loud when they pass. I rode past one yesterday (or rather, he rode past me) which had some kind of ridiculous turbo wastegate mod that nearly made my ears bleed.

Diesels don't even have an engine note. Just a single tone that sounds like "loud".

Same. Also, asphalt. If I could drive behind a hot asphalt truck all day, dammit I would.

Gasoline is my weakness.  Loved the smell of gasoline ever since I was a kid.  One day when I was 8 or 10, i decided to unscrew the gas cap on the tractor, which was on top of the cowling just in front of the steering wheel, and just stand there with my nose to the open tank and breath in the fumes.  Damned near turned green and almost fell off of the platform.  Didn't put me off of loving the smell though.

Yes, gas smells good.  Though I smell it frequently enough nowadays that it doesn't get me like it used to.  Asphalt or a school bus are rarer smells. :lol:

Leaded, 108+ octane race gas...  Almost smells sweet.  The newer, unleaded stuff has a much harsher smell.

Older diesels may smell depending on their level of exhaust cleaning, and France is way more relaxed about emissions than Germany. And I am stating that the NEWER diesels do not smell, especially once they've reached their optimal operating temperature.

I can only reiterate my experience with the new Range Rover diesels and Mercedes G350d, the Audi Q2 30 TDI and the new Mercedes E-Class Taxis (there's a taxi stand near my place in a quiet area, if a taxi idles I can't smell anything offensive when passing it).

Of course some older diesels will smell, especially many of the Eastern European diesels, which are probably entering this country without a catalytic converter and/or have their pollution control systems removed to save money. That's quite a common practice over there.

I have my RE-71Rs sitting in our second bedroom. I can smell tire shop anytime I want!
