"The entire chain of management" up to the French car maker's chief executive Carlos Ghosn was implicated in the "fraudulent strategies", said the report, which led prosecutors to open a probe into Renault in January.
Renault swiftly denied the accusations.
"Renault doesn't cheat," Thierry Bollore, the French car maker's second-in-command told AFP by telephone, saying all its cars complied with legal standards.
The report said there was no evidence of Ghosn having charged anybody else with approving the company's emissions control decisions, which therefore ultimately came under "his responsibility".
Police suspect the automobile maker of putting in place the strategies "with the objective of creating false results for antipollution tests", and so to be seen to be complying with European regulations.
Renault shares plunged on the Paris stock exchange, closing 3.7 percent lower, after the Liberation daily first revealed the existence of the report earlier Wednesday.
The document concentrates on recent car models, but the fraud investigators -- helped by statements by a former Renault employee -- estimate that questionable practices have been in place since 1990.
Several Renault models were fitted with electronic devices which detected test conditions and then triggered a temporary reduction in harmful emissions for long enough to fool the testing equipment, the former employee claimed.
The alleged fraudulent practice recalls the "dieselgate" scandal involving Germany's Volkswagen which admitted in late 2015 to installing so-called "defeat devices" into 11 million diesel vehicles worldwide, designed to reduce emissions of harmful nitrogen oxides while the engines were undergoing regulatory tests.
The German automaker last week pleaded guilty to criminal charges in the United States that it committed fraud by installing the devices and paid $4.3 billion in civil fines.
The guilty plea and fines were in addition to $17.5 billion that the company had already agreed to pay in settlements with car owners, dealers and for environmental cleanup.
Earlier Wednesday, state prosecutors in southern Germany said they had searched offices belonging to carmaker Audi over parent company Volkswagen's emissions cheating scandal.
Investigators from Bavaria, Baden-Wuerttemberg and Lower Saxony states searched "sites belonging to Audi AG and seven other locations" on suspicion of "fraud and illegal advertising", Munich prosecutors said in a statement.
