The wraps will come off the R.S.18, which will be raced by Nico Hulkenberg and Carlos Sainz this year, on February 20 - the same day that Sauber will reveal their C37 challenger.
Renault finished sixth in last year's constructors' standings with 57 points, but will be hoping to take a major step forward in 2018, the French marque's third season as a works squad since taking over the former Lotus team.
Confirmed 2018 launch dates:
Williams - February 15
Sauber - February 20
Renault - February 20
