Formula One fired up its final four-day pre-season test in Barcelona with British teenager Lando Norris topping the timesheets for McLaren as Australian Daniel Ricciardo insisted he was pleased with another solid session.
Ricciardo was 10th fastest in his Renault, clocking a best lap of one minute 20.107 seconds at the Circuit de Catalunya and putting 77 laps on the board.
"It was good mileage for us today. We pounded the laps in with longer runs and also completed some aero tests," the 29-year-old former Red Bull driver told Renault's official Twitter.
"It's good for me to sit in the car for a few hours to keep learning and building our knowledge of the car."
New teammate Nico Hulkenberg, of Germany, also put in some useful laps in the morning session.
