Renault's Jolyon Palmer is optimistic for the upcoming season after notable improvements made to the chassis.
The R.S.17 was given its first run of the season at the Circuit de Catalunya and the Brit believes the car has come on leaps and bounds from the rushed 2016 model that battled its way through their first season back in Formula One.
"The ride quality is where we were weak last year," Palmer told Autosport.
"We've made a big step this year. We've got much better tools to deal with that now.
"It's something we learnt from last year, and we learnt the hard way.
"But clearly [at Barcelona], we've made good progress, and even just the balance of the car is very consistent, it's very driveable.
"Every time I get in it, we know what to expect. It's a good feeling at the moment."
