"Renault would first prefer to keep the same spirit of the regulations because we've spent years now to work on that engine," he said.
"For us it would be a shame and not efficient to go to a completely different technology.
"That's where we are. Obviously we will take any changes into account but if we had to choose we would prefer to keep some stability."
With only limited engine development allowed each year under F1's 'token' system, Taffin said Renault already had long-term upgrade plans in place based on the current engines being kept so a major rethink would waste resources.
"We've gone into a way that we could develop for the next three or four years, that's why we've got these tokens and all these things," he said.
"It's fair to say that we've spent a lot of energy on this."
He added that his understanding was that radical change is currently unlikely.
"I know they've been talking about potential regulation changes but from what I know it's sort of on standby at the minute," Taffin said.
"From what I know, we're looking at keeping the same sort of regulations."

OPINION: Changes to the layout of Abu Dhabi’s circuit aim to reverse the trend of insipid Formula 1 races there - the promoter has even described one of the new corners as “iconic”. And that, argues STUART CODLING, is one of this venue’s abiding failings
Last year's Formula 2 runner-up Callum Ilott could be on his way to becoming the first Briton to contest a grand prix in an Alfa Romeo since Reg Parnell in 1950. But, says OLEG KARPOV, the Ferrari Driver Academy protege is having to temper his ambition at the moment – outwardly at least…
