    Diesel put a bad taste in people's mouth cause of the piss poor diesel engines from the 80s like the olds that was in everything and the anemic detroits in gm's. The diesels in german stuff are usually phenomenal on both power and fuel economy though and they last a long time. Every truck should just have a diesel in it honestly. A diesel option in jeeps and s10's would have made them an even greater vehicle. Running an off roader on homemade biodiesel and cooking oil is one of the greatest assets to have as an enthusiast

      huh, the 80s was a long time ago tho, most of us werent even born yet. Why havent they started using them again? Considering they get better mpgs than gas and are usually (i think) more reliable.

      Most people also prefer diesel engines, so its basically just a matter of manufacturers not offering them in new cars

            No. Turbocharging has been a part of the diesel induction system for decades, and, because of the need not to run a stoichiometric mix, doesn't require sophistication that goes with petrol turbocharging. You might as well invoke carbs vs fuel injection

            I see you're an idiot. As diesel is not a volatile fuel it's always required injection, ever since the first engines.

            Petrol is inherently less efficient as you have to make the inlet operate at less than atmospheric pressure to restrict the oxygen in the charge to keep it stoichiometric at anything other than WOT; with diesel you just inject the amount of fuel that's required.

        In the 90s high pressure injection for diesels became a thing. It vastly increased performance compared to the old diesels of the 80s.

        Combine this with a turbocharger and diesels were spitting out more torque, 80% of the power of a N/A petrol engine and vastly better fuel economy. This is before tuning them. Because they have a turbo, the power increase potential is vastly greater than any factory N/A configuration. BMW's lineup in the early to mid 00s is a classic example of this.

        American manufacturers didn't invest in this technology and were on the back foot. Volkswagen skirted some emission regulations during some recession era funding cutbacks and dieselgate happened.

        I have a 330d, first diesel car I've ever owned (260hp, 430 lb ft). It feels very powerful in day-to-day driving because the power curve gives you a lot of shove from 1500-2500rpm, which is where you are 95% of the time. In that rev range it feels equivalent to a turbo petrol with about 350-400bhp.
        HOWEVER
        the other 5% of the time when you want to push it it falls apart and you just get noise. There's legitimately no point taking it past 3-3.5k RPM.
        If you aren't interested in ragging your car and you just want an engine that gives you plenty usable power in daily driving then it's perfect, but it really isn't a performance engine. A 200hp (either turbo or NA) petrol car is more rewarding to drive hard.

        This 100%.

        Frog here. Diesel engines are a fricking bane. They're literal goycarts engines. Awful sound, pathetically low red-line, flat power curve, unreliable fuel injection systems, unreliable emission equipment. Frick Diesel engines, they're the reason all the 2000's french cars are extinct: there's no reason to work that hard to save a glorified tractor from the scrapyard where it belongs.

      dont forget that diesels also keep itheir gas mileage while driving on their top speed, which means better range and less stops for fuel. Euro diesels can make around 30 mpg easily at 120+ mph

      gas engines meanwhile make 10-12 mpg while on their top speed.

    Diesel missed its chance in the US because of a few shitty domestic engines back in the day as covered earlier in the thread, and then dieselgate when it was starting to recover.

        Not here. Op, diesels are overly reliant on the DPF system; it will literally shut it down. Diesel fuel gels in the winter, it's a dollar more a gallon negating any fuel savings. Plenty of torque, but no high revs to get off the line quickly. Old diesels had a switch on the fuel pumps to go to manual mode, it'd run until out of fuel, no battery required. These designs are long gone.

    I bought a new manual diesel Jetta back in 2012. Was an awesome DD as I drove long distances working for the RR. It was slow as frick, 0-60 in 9 seconds but the 40+ mpgs were a god send. And the interior was a very comfy place to be.

    Then dieselgate struck and I traded it back. I paid $26k new and got back $21k when it was all said and done. I used that cash to buy my current Tacoma.

    I still wish they made diesel cars it would be my next car purchase but all the new cars are super gay so I stick with my Taco. Hell a diesel Taco would sell like hotcakes but the cat piss requirement ruined modern diesels.

    Diesel is the superior fuel. Modern diesels need that DEF and EGR to be sold so that is a hurdle to be crossed with deletes at some point in their lives.

A bit quicker off the line, but past 20mph is gonna be slower. Better fuel mileage, but higher purchase and repair costs. Sound like shite. Smell like shite.

      You're right about everything except this. The reason Diesel is more in the US is because our refineries are set up to crack crude into more gasoline than diesel so less of it is made. Fuel taxes are about the same too on both unless you're running a Semi in which case you're filling out a form 2290 and equivalent in state taxes.

        European nations specifically put upwards of €2 a gallon in taxes alone on gasoline that isn't on diesel. There's a reason why gas costs $8-9 a gallon there whilst diesel is closer to 6. The EU explicitly mandates memberstates place a sin tax on gasoline but not on diesel.

          Man, I'm just trying to say that

          EU created laws and regulations in the early 90s to incentivise diesel ownership over gasoline, because it was thought at the time that diesel produced less pollution than gasoline. People only bought them because that's all they could afford.
          For a daily commuter to just own and putt around town in, a 21st century diesel passenger car is not going to feel appreciably different than a gasser. A bit quicker off the line, but past 20mph is gonna be slower. Better fuel mileage, but higher purchase and repair costs. Sound like shite. Smell like shite. Diesel fuel costs more outside of Europe because of the aforementioned taxes and regulations designed to disincentivise gasoline use.

          wrote about costs, not taxes or policies, and that's the only thing that I can't fully agree with in his post because in some places diesel is a bit cheaper at times and that's all an average normalgay is able to care about.

    I have a 330d, first diesel car I've ever owned (260hp, 430 lb ft). It feels very powerful in day-to-day driving because the power curve gives you a lot of shove from 1500-2500rpm, which is where you are 95% of the time. In that rev range it feels equivalent to a turbo petrol with about 350-400bhp.
    HOWEVER
    the other 5% of the time when you want to push it it falls apart and you just get noise. There's legitimately no point taking it past 3-3.5k RPM.
    If you aren't interested in ragging your car and you just want an engine that gives you plenty usable power in daily driving then it's perfect, but it really isn't a performance engine. A 200hp (either turbo or NA) petrol car is more rewarding to drive hard.

    Ever think about why almost every single piece of serious machinery uses a turbo diesel engine? They are phenominally reliable often exceeding 15.000 hours and more before needing a rebuild. They also provide great fuel economy and a wide powerpand with a lot of torque rise. The problem is that car manufacturers don't innovate for the sake of reliability. If they're not developing something because of government cucking, they're developing novelty bullshit that makes passenger cars continually less reliable. The best Diesel you can buy is a Tier III pre DPF and DEF with commonrail injection and a VGT. Engines peaked in 2005.

      Just buy the new diesel and take that stuff off. Best of both worlds.

        This cannot be done in Europe and cucked US states. On my south american shithole they only test exhaust clarity so you can do whatever you want.

      I don't think OP is going to looking at some heavy machinery to buy, anon. Read his post:

    I like them, they usually need emissions deletes/tunes but after that they are mostly reliable and make good power.
