Diesels have only developed due to the Climate change b*****k*. Before, they were seen for truck & van engines. People who had a diesel car were strange, like leather elbowed teachers, or those who could nick diesel from their truck and tractors. Normal people wanted a car they could start without a cloud of blue smoke.
So every manufacturer needed to develop new engines that ran without knocking you fillings out, but to do that they had to spend billions on such things as Dual mass flywheels, oil filled mountings or electronic ones.
They developed so fast they became better and the final piece fell into place when they got tax advantages.
I have driven them for hundreds of thousands of miles and they are the ideal lazy mans car, stick it in top wind up the turbo and they fly, on a motorways, they are refined now but they are still not nice to drive if you are enthusiastic at all. People love the torque but hate the costs of repairs as they are biblically expensive when they go wrong.
But they are perfect for our stupid limits, bad roads and tax regime.
A true petrol head wants the thrill of revs, to feel you are working something to get the best out of it not just sitting pressing one pedal.
The sport moniker is just advertising spin. My X type jag estate had the sport pack, better seats , worse ride, but it was still a soulless engine that did what it should. A v6 petrol version would have been perfect, I had one on loan when the diesel broke down, but it would have crippled the company with the fuel consumption.
Now the tree huggers have been shown the errors of their ways and instead of saving the planet they have helped to kill millions due to the cancer causing particulates, we are going back to developing petrol again. Who cannot be excited by a three cylinder rev hungry engine that can kick out 250 bhp and this will get better as cities around the world ban diesel cars.
But this is all academic as in a few years time we will argue about electric motors and hydrogen, in the same way steam lorry drivers did years ago against diesels
