And this is why I drive a 1980 Volkswagen rabbit pickup. better gas mileage then modern cars (50mpg+ on the highway) I can replace about any part in it for under a few hundred in most cases even a new engine can be done under 1000. And everything is dead simple to work on no fancy computers or anything.
How about those crumple zones? Feel safe in your passenger cage? Hope you’re shorter than the dashboard in case of a rollover. Don’t have to worry about getting hit by those airbags, do you? Imagine that steering column spearing through your chest
New cars aren’t just about the latest infotainment, gadgets, and design. There have been huge improvements in pollution control and safety. There has also been huge improvements in efficiency, even if they’re masked by the increased weight of safety improvements, increased performance, and generally much larger size. So far a lot of that increased complexity is well worth it - I’ll never have another car without anti-lock brakes
They mostly are, companies don't care to innovate anymore, only to sell.
Safety? Some, sure. Pollution? The only reason governments regulate is because car companies want to sell you a new car every year. Ooops, big bad government whom we happen to have in our pocket wants Euro5 now...
More weight/size = more raw materials, is it really that good for the environment?
If companies and governments are so keep on being green (they're not) they'd ensure cars are easily repairable and upgradable. And they'd keep supporting older models - design a more efficient engine to replace the one in the older car why won't they?
If a vehicle doubles in size, vastly improves performance, and still has similar efficiency, yes, that’s a win. If it improves safety enough to save tens of thousands of lives every year, yes it’s worth it.
That's the only reason I bought a modern car.
My parents would always buy cheap beaters. They had a car from the 90s they only recently got rid of because the transmission was shot. My first car was an '05 Caravan I drove for almost two years and got rid of in 2018.
I swallowed the pill after seeing cars get absolutely crushed to the point where the jaws of life were necessary yet passengers could just walk out.
I remember someone posted a picture of their brand new sedan. It was involved in a serious accident and sandwiched between two large pickup trucks. The entire car was squished down until it was smaller than the passenger compartment. The driver was able to walk away with minor injuries and the paramedics weren't even surprised.
I don't give a shit about the fancy features. I just want something that is reliable and safe.
Polluting as hell though, or so I imagine?
Even in Sweden catalysators were not mandatory before like 1986 IIRC.
The rest is awesome though 👍😎
And what are the pollution costs of even manufacturing a new vehicle, VS one that's already in place?
We can't manufacture our way to using fewer resources.
Why not? Seems like a pretty simple formula: if it costs X amount of resources or pollution to save Y amount of resources or pollution per unit time, the break-even point is whenever Y times time exceeds X.
You can, though. There are many lifecycle analyses using actual data to calculate the tradeoff point.
This depends a lot on how much the one already in place pollutes, vs the new one.
For an EV vs a slightly older ICE, on your average western power grid (so not fully renewable, but not fully coal either), it takes just a few years till the EV's total lifetime emissions are less.
Oh yea it's a straight pipe diesel ain't anything good for the environment gonna put a slightly more modern engine in it at some point for some more power the 1.6l in it currently only makes like 50 horse so when I do that it'll be a little better but still not great
Well there are a bunch of reliable late 90s and early 2000s German engines that would make that thing ridiculously fast compared to now, pollute less, burn less fuel, and would be pretty easy to maintain.
Long as you avoid all the ones with known pitfalls and research standalone ECU options first of course.
I'm partial to Mercedes engineering myself, I'd tell you to use an OM646. But there's nothing wrong with an M47 or a VW 1.9 tdi either. The PD version of the tdi is slightly more complex than the oldschool versions (66 and 81 kW), but would get you ridiculous performance and fuel economy considering how little your car weighs.
Of course if you had more space in there, I'd suggest an OM648 or M57, but I don't think you'd get an inline 6 to fit. MAYBE an OM647 since it's an inline 5?
You can get a inline 5 in it cause I know you can fit a o7k or a vr6 lol. my plan was to swap it to a TDI I actually have an 01 TDI sitting here for it just don't have the money currently to finish it but once i do, this TDI is actually supped up some pushing 20+ psi of boost not the I will probably run that much since I plan to daily it but it can
