Renault's has been working on some "very, very good stuff" regarding its new power unit, according to Cyril Abiteboul.
Following three wins with Red Bull in 2014, Renault suffered a disappointing season last year and failed to win a race amid uncertainty of its future in F1. Eventually the French manufacturer opted to return as a constructor, while its deal with Red Bull will continue but the power unit will be badged as a Tag Heuer.
Asked how development of the power unit has been progressing over the winter, Renault Sport Racing managing director Abiteboul replied: "It’s going well.
"We have some good stuff in the pipeline, which will take some time to get implemented and seen and visible on track, but we have very, very good stuff now."
And Abiteboul admits the update tested during the Brazilian Grand Prix in 2015 led Renault to focus on certain areas which required attention.
"We know where we need to work. It was already in the same area as the one that will be massively changed in the course of this year. It’s not exactly the same concept, but it’s the same sort of geography of the engine."
