Renault will hand drivers Daniel Ricciardo and Esteban Ocon an upgraded car for the forthcoming double-header at Silverstone.
The team has endured a mixed start to the new season, finishing a high of eighth in each of the three grands prix to date, while also retiring a car in the first two races.
Although chassis technical director Pat Fry believes the results have been "where we deserve to be" he also at least feels the R.2.20 is an improvement compared to last year's car, proclaiming Renault to be "amongst the teams to have made the most progress from last year"
But Fry warned: "There’s obviously a lot of work to do and we have to keep developing. Reliability has been disappointing and it’s frustrating to have those problems.
"We’re working hard on this and we need to improve all of our processes, from quality assurance through manufacturing and the build phase, all the way to the implementation on the car."
To that end, the car that will take to the track for the British and 70th Anniversary GPs at Silverstone will be an improvement again.
"We are bringing a number of updates to the car this weekend as well as running a different downforce level," added Fry. "It’s a reasonable update and it will be interesting to see how it performs at Silverstone.
"I wouldn’t say it’s enough to shake up the order but it’s a good upgrade at this stage of the season.
"Silverstone is a good circuit to test these things, it has enough straights for measuring the aero performance as well as a great mixture of corners so we can really gauge the effect on the cars handling. If it’s dry, we’ll have an idea of what’s going on.
"In the past, our car hasn’t been suited to this sort of track but, this year, the signs are there that we’re heading in the right direction."
