Renault insists they are committed to delivering their best this season despite having to pump a lot of their resources into next year's engines.
The French engine manufacturer are supplying V8s to Lotus, Red Bull, Williams and Caterham this campaign, but with Formula One switching to turbocharged 1.6L V6 engines next year a lot of effort has gone into building units for 2014.
This has left a lot of manufacturers in the unenviable position of having to do double the work ahead of the changeover.
However, Renault F1's technical director Rob White has assured teams that their needs won't be neglected this season.
"For 2013 it has to be business as usual," he is quoted as saying by Autosport.
"We must deliver to the tracks the engines necessary to go racing. We must provide to the teams the full support to optimise the performance for this year's car, which is different to last year's car.
"And we have to ensure that we don't cock it up and back off too soon."
Renault, who this week became the first manufacturer to release images of the new V6 engine, have been putting in extra work on the 2014 power units during the off-season, but they won't get sidetracked when it comes to reliability for this year's product.
"There is not a V8 to do for 2014, so already upstream there will not be any longer term work," he said.
"But there will be a lot of work to do on the new 2014 project, which will occupy a greater proportion of the factory based resource than the 2013 engine.
"Obviously this season is the one where the factory-based workload is more critical in the late stages of design.
"We have been in F1 for a long time and one of the lessons we have always learned is that you cannot mortgage the present to pay for the future.
"So we are very committed to succeeding in 2013. The urgencies of 2013 will take over from the important 2014 stuff, but hopefully we have built the foundations of 2013 to ensure we are left without too many surprises."
