Renault Sport's R.S.20 was left under the covers until the very first day of testing, as the team's launch one week earlier didn't show the car, quite simply because the team weren't ready building it. In fact, some renderings shown at the time revealed a mostly black testing livery to cover up most of the details, while also giving the team more time work on the final race livery as well.

Not much was revealed by the team about the R.S.20, especially not about the chassis, as the team's technical director in charge of the entire development, Nick Chester, left the team at the end of 2019, and was replaced by Pat Fry, who only joined in February 2020. But that was just the top of the iceberg, the team saw many changes in leading positions in the year running up to 2020. Dirk De Beer, for instance, rejoined the team and ousted Peter Machin as Head of Aerodynamics. Matthew Harman, previously deputy CD, moved to be Engineering Director while Steven Booth filled his shoes, moving on from 5 years as Head of suspension design.

Team Cyril Abiteboul said at the team's season launch that there simply was no point in presenting a dummy car, like they had done so repeatedly. Later in testing, the story was already a bit different by admitting that the team hadn't had the smoothest of development programmes for the R.S.20.

On-track performance

Pre-season testing ended up to be fairly positive for the French team, especially in the final few days of the tests when Daniel Ricciardo managed to set the third fastest time of the winter test. Lap time analysis also revealed the team were pretty strong on longer stints, ranking third and 0.7s/lap off Mercedes' pace and just 0.1s/lap slower than rivals McLaren.
