Absolutely the contrary, NEVER BET YOUR WAY
... look the evidence is there. The stupid obsolete petrol engine has had more than 100 years of development in motorsport ... and the problem is the fuel not the mechanical parts by themselfs. Petrol doesn't allow high rates of compression due to physical and chemical proprieties of the substance... and because of that, including those physical and chemical proprieties, is a "slow burner" compared with Diesel that literally explodes inside the cylinders under high compression. Experimental engines have achieved rates of 40:1 in volume compression
The trick developed for petrol engines, along a century of experimentation, is mechanical balance of the moving parts... time that "sport" high RPM diesel engines haven't had yet... allowing the injection of large amounts of fuel(petrol) in the cylinders to overcame its "slow burning" mode. Upon doing so the engines became very noisy, because a high rate fuel injection gives the engine the necessary energy to achieve high RPM (otherwise not possible), but its TORQUE is MEDIOCRE because a relative high percentage of that injected PETROL BURNs in the EXHAUST PIPE... the reason for the NOISE... and the reason why PETROL engines will always CONSUME MORE FUEL... in "endurance" type race rules, 9 liters difference in full tank between petrol and diesel, in favor of petrol, yet in pit stop accounts diesels have always won in its category.
Rule of thumb you can apply with any super-engineer "petrol head" that love "oil oligarchs"- scum of the earth; is that NOISE is a clear sign of INEFFICIENCY NOT POWER... if "he" objects, suggest him vacations in the Gulf of mexico for him to take deep plunges in the pristine waters of the "Caribe" sea.
The bottom line is; is motorsport to promote PURE SPORT or the profits of carrier criminals and their substance infested with war blood ?... Petrol engines make Oil Oligarchs, special high performance, to have psychotic psychological orgasms, of how a single device as contributed so much for their criminal fortunes in detriment of the planet and all its peoples. Because the pressure and influence to make such "unjust" regulations against diesel by the ACO, must only for sure have the fingerprint of those greased greedy little fingers of the scum of the earth.
I don't know how to put it... but if one is smart and not a dumb, a stupid petrol head (NOISE=INEFFICIENCY) sheeple, one would never buy a petrol car again... ever... more so if one loves speed and powerful cars.... i had a VW Golf II 1.9TDI rated 115HP and with a change of turbo (NO NOT that much turbo pressure) and control box tweaks and an adapted Passat gear box transmission( more robust).. and i had a 270HP motor at the dynamometer... for less than 2000€ ... yet consuming substantially less than an equivalent rated petrol engine, FOR SURE... what an "overhauling program" it would not give!!... those engines come "cut" from factory by the same scummy greased greedy little fingers influence.
FOR SURE... if Audi or Peugeot wants to win LeMans again they will stick with Diesel... unless Diesel is abolished, because so far even with clearly "unjust" unjustified rules against Diesel, Diesel has not only won since 2006 but it has delivered a severe beating to petrol every time !... only a blind could not see that. And for sure if Diesel remains we will never see equal rules but only prejudice against diesel... if ACO is to maintain its vast sponser network...until we get out of oil...
