5 Reasons Why It’s Time For Diesel Cars To Die
Diesel fans, your days are numbered.
Apologies if that sounds a bit harsh. It’s not that I hate diesels. Actually, I do hate diesels, but not in a rage-inducing you-just-opened-your-door-into-my-fender way. It’s more like the oddball uncle you tolerate at family gatherings, the one who acts like a total douche but doesn’t realise he’s a douche, so you hate him, but at the same time you can’t really blame him. That’s how I feel about diesels, at least in passenger cars and pickups outfitted with stupid chrome stacks or ridiculously oversized exhaust tips. They are what they are, through no fault of their own. I’d be very happy if they just went away forever.
And that could well be happening soon. Paris, Madrid, Athens and Mexico City have taken steps to ban diesel cars and trucks by 2025. There’s growing pressure for London to follow suit. Germany wants to ban diesel and petrol car sales by 2030, as does Norway. Banning internal combustion cars will be all but impossible until electric and hydrogen power are better sorted, but with sights leveled against fossil fuel power, dirtier diesel is the one wearing the biggest bullseye.
I can hear diesel fans hashing away at their keyboards even as I hash away at mine. Fuel economy! Torque! Longevity! All valid points . . . if it was 1997. Diesel’s advantages are quickly disappearing in the face of advancing technology; if you don’t believe that, just Google dieselgate to understand just how bad things are. Or, you can ponder these five points as to why I think diesel is on death’s doorstep.
There isn’t any other way to say it - diesel is a dirty fuel to burn. The only way it’s still viable is through the use of increasingly complex technologies to capture soot and reduce NOx, and even then it doesn’t work unless you sacrifice performance or fuel economy - a fact that Volkswagen has so dramatically shown the world with its “clean diesel” technology.
2. It’s complicated
Perhaps new technologies can make diesel cleaner to burn, or better capture those emissions. Perhaps we can add more pee (sorry, diesel exhaust fluid) tanks to the car to make the pee (sorry again, AdBlue fluid) last longer. Perhaps we can add more filters and exhaust devices, in turn adding weight, complexity and expense. But what is the ultimate goal here again? To have a car that equals petrol engines on emissions and performance and matches hybrids for fuel mileage? I’m failing to see the diesel benefit here.
If anyone’s ever witnessed a runaway diesel engine firsthand, you’ll never forget it. Yes, this is a fairly rare occurrence and many manufacturers claim to have safeguards against this, but that didn’t help this Peugeot. Nor the new Silverado pickup truck, BMW, Ford, or any number of the cars featured in runaway videos on YouTube.
4. Petrol engines have gotten better
Once upon a time, the big advantages to diesel over petrol were fuel economy and longevity. 250,000 miles is easily achieved in modern petrol engines with basic maintenance, and there are all kinds of new petrol hatchbacks on the market with amusing turbo performance and fuel mileage ratings exceeding 40mpg on the highway. I will readily admit that diesel engines still hold an advantage in both areas, but the gap to second-place petrol is much closer. Is that advantage enough to justify diesel’s drawbacks? That’s for individuals to decide, but I think a majority of motorists will say no.
There’s nothing diesel can do that electric motors can’t do a gazillion times better. Low end power? Electric gives you max torque right off the bat, and it can hustle a Tesla four-door sedan to through the quarter-mile in under 11 seconds; quicker than virtually every ultra-exotic hypercar in existence. It doesn’t burn fuel so there are no emissions to worry about. Electric motors are very simple with just a few moving parts so lower maintenance and longevity are virtually assured. The only issue - for now anyway - is improving battery power and range. But viable electric cars are evolving like crazy, and I suspect we’ll see electric cars with 1000-mile ranges in the next 5-10 years.
With that in mind, why on earth would manufacturers continue to invest in diesel power - utilising a dirty fuel that will require increasingly complex solutions just to maintain average performance at best - when electric and fuel cell development will lead to significant improvements on all fronts? Diesel still has a place with larger commercial vehicles, where the gap back to petrol and the jump forward to electric is still a fairly large one. But for passenger cars and light trucks, better petrol engines and far better alternative power solutions mean diesel will finally get the merciful death it deserves.

1 classic example of ‘i can see it and I can smell it therefore it must be worse’ logic.
2 if adding Def is complicated you’re not very bright. It’s the system that uses the Def that is complicated. Which is an automated system.
3 nothing crazy about a runaway. Just let it roll and get it into a high gear and start forcing it to stop. Another way is to block the intake so it chokes or dump a fire extinguisher into the air filter. Spraying the intake with any heavy inert gas will kill the engine. Even if you don’t manage to stop it, it will stop itself when it runs out of oil or comes apart.
4 diesel still wins in longevity and mpg.
5 I’ll give you that one. Electric is obviously the future.
Aaah, how cute. Some had his ass handit over to him by a diesel didnt he? And now he is a tiny bit mad.
I disagree.
I see few reasons why diesel won’t go away any time soon:
So diesel-electric hybrid maybe? Maybe when price is competitive to older VAGs 1.9 TDIs
Generally i agree that diesel is annoying. Smell and noise…yuck. But bills don’t get paid by smell or lack of it so cheaper goes. Banning them from bigger cities that have public transport for replacement - why not. I even approve. What about Intercity commuters and rural areas?
1: only reason there was a problem was because the public wanted their diesels to be as fast as their petrols, Honestly, most cars are used in the city where acceleration isnt needed, but good emissions at idle and low power is good, sounds like a diesel.
2: at the aforementioned lower power levels, you dont need additives to keep it clean, no spark, no additives, less complicated than the petrol engine.
3: with normal maintenance it wont run away. Sometimes petrol cars have issues too.
4: so have diesels.
5: I’m in the middle of Australia, between here and the nearest major city there are stretches without permanent settlement for hundreds of km (or miles if it makes you feel better) electric vehicles will need to improve alot before they will be feasible here.
But you know, I guess you can single out diesel as being inferior if you are into petrol cars only.
Now I’ve seen some dumb, uneducated clickbait drivel on this site but this really takes the cake.
You find me one gas engine that makes anywhere near the power of a similarly sized diesel while returning similar fuel economy, you might have a point.
Also diesel exhaust looks dirty, but it’s primarily soot, with a little bit of NOx (which is only present in really high-efficiency diesels, not much in older pickups or semi trucks). Soot settles out of the atmosphere quite quickly, whereas gases like carbon monoxide and dioxide (like those produced by a gasoline) do not.
Don’t get me wrong, diesels aren’t perfect, but they’re way better than a 2 ton stack of batteries and an electric motor. Why? Because I can still buy a diesel with a stick shift. Find me an electric with a standard…
Damn, forgive all my grammar errors, was gonna fix them but I haven’t got a clue how you edit a post on mobile… Maybe you can’t edit it in the first place…
so I know a guy who has a 2013 audi a4 3.0 tdi. nice car, fairly fast (he bought it for performance). But a petrol 2010 s3 with two less cylinders is faster! petrol is better than diesel, and so is electric power.
Can I down vote posts??? This is the first time I’ve ever wanted to..
Improving upon the technology we have is the way forward. Why not keep the internal combustion engine and modify it for better fuels(I.E. Plant based fuels), while implementing further refinements along the way. Anything is possible.

Here in chile gas is almost twice as expensive as diésel and you get better mileage in the diesel. I’d love to buy a ram 1500 with the hemi 5.7, but al though it is a lot cheaper than a 2500 with the cummins, I’d be financialy ruined in no time with the hemi, and the cummins gets good fuel mileage, lots of power and diesel is cheap. When electric gets to mases its the end of petrol and diesel, but not everybody can affor a 35000 usd tesla (respect to tesla for this massive step towards emision free cars for everyone though).
