This thread is so making me laugh.
I am in the lucky position of having driven several hundred thousand miles in tens if not hundreds of different cars.
Yes modern diesels are getting quite good at what they do, compared to diesel engines of ten, fifteen years ago they are light years ahead in every area. I have driven petrol cars I like and petrol cars I detest, and the same goes for diesels.
One thing that does emerge from all my experiences though, is that you have to modify a diesel engined car to make it do anything at all. A standard NA diesel engine is just pants, there is no getting away from it. A standard NA petrol car can be very engaging and fun, you do not HAVE to bolt a turbo to a petrol car to get a usable engine, and that to me says it all about diesel engines.
If we take it to the extreme and look at performance diesels, have a look at the Le Mans winning Audi R10 for instance. The only way that Audi could make a competitive diesel engined car was to get the rules changed to let the diesels enjoy a 50-percent larger displacement limit, a 52-percent larger intake restrictor, and an absolute boost pressure limit nearly twice as high.
Additionally, the diesels are allowed variable nozzle turbines in their turbochargers, it is also rumored that Audi successfully lobbied to raise the minimum weight to accommodate the R10's massive (at 200kg nearly 50% heavier than an equivilent petrol engine) powerplant. If these rule changes had not been implemented, there is no way on earth the diesel would out perform the petrol engined cars.
