I'll have to disagree with you on the removing emissions thing. I remember what it was like driving in traffic in the early 70's with no emissions equipment. As a kid I remember it was not good sucking in all those unspent hydrocarbons. Now I sort of put it on par with sucking in the exhaust from my 27 year old lawn mower.

I do agree with you on the difference between the 4/6/8/12 cylinder NA/Turbo engines.

But even when I built a 350 4 bolt main with a 375 horse cam in my 1976 Nova I put high flow cats in my dual exhaust.

I grew up poor in Los Angeles in the 80s - that meant every car around me was a beater muscle car from the 60s and I spent a lot of time choking on exhaust. I remember smog warnings on the news, stinging eyes on bad days and looking down from Griffith Park Observatory on the dirty brown blanket that concealed the city, just the tip of Library Tower poking through. So I do care about all that and tend to run my cars in the least impactful way.

That's not to knock anyone else's decisions, and LA is a particularly smog-prone region, but it's context on why I think about this stuff.

You think too much.

A new car that is clean should be the better choice.

Personally, I think you only need to be concerned with that which you can control. Drive a car that gets good gas mileage, doesn't leak or spew smoke. If you sell the car when you are done with it, then the next owner will deal with it, and your impact of construction and shipping and such, is moot.

:rofl:

Someday..............someone will offer electric conversion for our E53's!

Until then..............enjoy your ride!:D

I got 13.9mpg in my last gas tank. That's with me driving semi-reasonably and not turning every green light into a drag race (the 4.6is is surprisingly good at this with its 3.91 rear end). My 540it gets better mileage but its AC doesn't work as well as the X5's, so I've been driving the X5 for the past few weeks. It's only like $15 more per week in gas so it's not a big difference to me.

Well, I live somewhere where it's extremely cold in the winter. According to the America Automobile Association in southern California extreme cold could reduce range of an electric car by up to 57 per cent. For starters, they don't have a satisfying range, add to that the fact that one has to keep warm during "idling" and then you prey you will get home. Oh, I forgot, the study is made I believe, assuming the batteries are like new - I don't think they accounted for an old set, because then you're trouble for sure. Now, another thing, lithium is quite a rare material. Much rarer than crude. Nuff said about planetary depletion of rare metals. So, if I have to drive to Edmonton for example, I should do it only during summer, because in winter there's the risk of one never getting there, and then probably being found in spring somewhere in the ditch. Or as a block of ice if found the same winter. Because stranded on the road. Assuming I get there, and if there's an emergency and have to get back home, or if I don't want to overnight, then you have to "fuel" up. My X5 takes a couple of minutes to fill up.......and the tank is big. How long to fill up the batteries? Yeah, there aren't many charging stations and most are 110 that aren't very fast charging. Not sure about greenhouse gas emissions done while building and recycling battery packs, or how bad it really is.
By saying this, I also reckon there are some other engines in the works - fuel cell comes to mind, but I don't think this will happen during my life. I would certainly rock one of those.
