That 4.2L V8 you mention is only doing 3225 RPM (quite low RPM, quite economic for such a big engine... or "hp" numbers are sandbagged(a lie) or even electronically cut(or artificially crippled), to not scare away costumers for the cheaper to make more lucrative petrol alternatives $$$... at 4200 RPM very easy for a well balanced V8 diesel (bah! i rided a VW polo GT diesel 3 cylinder - 80hp pushed 4k RPM) would be 501 hp on your saloon... even any knowledgeable street corner tuner could do that, to that 4.2L V8 diesel

I bet the 4L V6 TDI could yet do above 4K RPM on the 2014 fuel rules, in video of 2013 is easy to see above 4500 RPM, even with peaks close to 4900
So 4300 RPM with 950Nm gives 578 hp ... 4500 RPM with 1000Nm gives 631 hp ... 4900 RPM with 1000Nm gives 688 hp...
If a diesel engine would have the typical road sporty petrol red line at 7000 RPM , and the same typical torque of a big racing diesel(1000Nm)... it would have 983 hp lol
So ranting a big diesel engine is too big and is not fair... equal ranting applies for 10K RPM is too much and is not fair... why not trade, in fair limits ? (because the diesel would win LOL -> and its scary for many because there have been testes of push to break on V12 diesels engines already close to 8000 RPM... imagine that
LOL)
