Ferrari's Charles Leclerc was top of the timesheets as Formula One wrapped up the season with a final test in Abu Dhabi on Tuesday.

His former teammate Carlos Sainz had a first full day with new employers Williams, and was second fastest, while a cast of young hopefuls replaced race regulars to get valuable track time in the latest machinery.

Sainz did the second most laps, a total of 146, equivalent to more than two and a half races at the Yas Marina circuit, after RB's Liam Lawson (159).
