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.

You keep on saying diesel is a dirty fuel than regular gasoline but it actually isn’t with new engines, the new filters and technology capture 93% of the emissions that the engine puts out. So that’s 93% less emissions that diesel cars out out than regular gas online cars. And you say that the emissions that they put out are worse than what gasoline cars put out but the fact is that the DEF fluid neutralizes the NO that the engine puts out so it’s putting out the same green house gasses and toxins that a regular gasoline engine put out it’s just putting out 93% less of those gasses and toxins. And diesel cars are not supposed to have a stream of black,blue or white exhaust coming out of their tail pipe unless there is a problem with the car, same as regular gasoline cars plume out blue exhaust when they are burning oil. And yes some people modified the fuel injectors in their trucks and out smoke stacks in their trucks to role coal which I do agree with you there is dumb because it is bad for the environment and lowers your fuel economy. And I drive a hybrid car but am getting a diesel suv because it is more practical for me but as for hybrid and electric cars if you read into the study’s they actually make a lot bigger of a carbon foot print to make than regular gas and diesel powered cars. Production to the end of a hybrid or electric cars “life time” they have a bigger carbon footprint and emit more emissions into the air than production to the end of a gasoline or diesel cars “life time”. Also electric cars are dirty they might not have a tail pipe but the electricity that charges their batteries makes emissions unless they are charged with renewable energy but we are not there yet where most electric cars will be charged with some source or renewable energy. Most country’s still rely doninately on coal or natural gas for electricity. So in theory electric cars could end up eventually being good for the earth if we learn how to make them with less of a carbon foot print ie using renewable energy to make them and charge them but that if still decades away. And hyrdrogen cars sound good in theory but the way they would get hydrogen fuel for the cars is from natural gas which would still emit C02. I am all for better fuels and making less of a carbon footprint in earth to save it but in reality as of right now we don’t have the technology to make any cars that are zero emissions. If you look into the studies the best car for the least emissions production to the end of its life are diesel and then regular gas cars. Diesel use to be a dirty fuel but right now diesel cars and regular gas powered cars are the cleanest cars we have emissions wise from production to the end of their “life”.
