Even though the weather is cold, it must be Spring. After all it's April the flowers are coming out and so are the Diesel detractors!
A view based on reality from an actual owner, as opposed to views based on myth and prejudice.
My Ghibli Diesel will be four years old at the end of July:-
Average over 32mpg with easily over 40 on a motorway.
RFL at about half that of the petrol
Real world performance thanks to 600nm (which is more than the Ghibli S), which is more useful and impressive in real world driving than the boy racer performance of the petrol.
Admittedly, only once warmed up, refinement in everyday driving making it indistinguishable from the petrol. Plus in Sport mode an exhaust tone that mimics the sound of Ferrari V8.
Externally nobody knows what engine the car has, as there is no badging anywhere in the outside of the car.
For those diehard petrol lovers, I would imagine you could pick up a V6 petrol model cheaper. After all the engine is woefully out of date and inefficient - just look at the new gen V6 engines coming from Korea for example. The block is (I believe an Iron lump) manufactured in the U.S by Chrysler, shipped to Ferarri for assembly as they have the facilities to do that, not to be confused with one of the proper hand fettled engines used in one of their supercars. In fact when owners say they have a V6 Ferarri manufactured engine in their Ghibli or Quartroporte, I am reminded of the first Seat Ibiza which proudly proclaimed it had an engine designed by Porsche.
Ferrari did develop the 3.0 petrol engine, but that was alongside the diesel.
Finally, given that future generations of Maserati will be pioneering electric vehicles, I am not quite sure what those Spring Diesel haters will say then - powered by a washing machine motor?!?
