1. Diesel Engines are more expensive to produce than petrol, thus diesel engined cars are proportionally more expensive.
However they depreciate less, so its swings and roundabouts there.
2. They cost more to maintain especially as most of them are turbocharged to make them perform like petrol engines.
Granted turbo's can fail and that is costly, but diesels tend to take high mileages a lot better than petrols, and they are a lot tougher. Something like head gasket failure is very rare on a diesel, as is a snapped cambelt. There are also no spark plugs to replace. Just some glow plugs, which aren't usually on the service schedule anyway, indicating that they are expected to usually last the life of the engine. My JTD used no oil, no coolant, nothing between services at all, and it costs more for an oil change on my V6 than it did on my JTD. So I would disagree with you that diesels are costlier to maintain.
3. The average man in the street who drives a diesel, drives it like a petrol. Some wear out the turbo and are therefore faced with more repairs.
How do you drive a petrol then, as opposed to driving a diesel? Are you talking about a normally aspirated petrol? As 99% of the time I see people driving their petrol engines in the rev band that you would typically associate with a diesel engine, ie under 5,000rpm. Why own a petrol if most of the time you are barely getting up to peak torque, never mind peak power? I think the low down shove from a diesel is ideal for day-to-day driving.
Anyway, a turbo wears out due to maintenence issues rather than driving style. My JTD was sold with 122k on the clock, on its original turbo, my current daily driver, ten year old Mondeo with 146k on the clock, still on original turbo. Contrary to what some people believe they don't wear out often, if they do its usually because of a design flaw with that specific car (eg previous model BMW 320d)
4. Most of them suffer from terrible turbo-lag which makes them unpleasant to drive.
The Mondeo I have has terrible turbo lag. No torque until 2,000rpm. However, last time I drove a 1.8 petrol it seemed there was no torque anywhere in the rev range!
My JTD didn't suffer from turbo lag though, it had masses of grunt anywhere in the rev range, and was nothing like unpleasant to drive. That tidal wave of torque is definitely just as exillerating as the revs building towards 7,000 in the V6 I drive now. Plus you can use that torque all the time
5. Diesel is more expensive than petrol and the gap is widening.
Can't argue with that, but Mondy doesn't mind half the tank being full of cooking oil at 50p a litre..
You can't do that in a modern diesel though.
The fumes aren't nice, but the fuel itself smells nice.
I think you meant to say they sound terrible. Thats what I would have said anyway, you can't argue with the fact that diesels just don't sound as good as petrols.
8. They polute the atmosphere. The majority of photographic smog in big cities is caused by diesel vehicles.
Petrols pollute the atmosphere too. In fact if you are using more fuel you are polluting more. It is less noticeable at ground level though, and there isn't as much NOx or particulate matter in a petrol's fumes.
9. All in all they are thoroughly unpleasant and the person who invented them should have been strangled at birth.
Otto Diesel, and what a clever man he was
Mark my words, compression ignition will be the future of all engines
10. I voted for Petrol
So did I
