Mercedes completed 107 laps of the Circuit de Catalunya on the final day of 2017 pre-season testing in Spain, taking total winter testing mileage for the new F1 W08 EQ Power+ to 1,096 laps - 5,102 km.

Both drivers were once again on duty for the eighth and final day of pre-season testing with Valtteri Bottas taking on the morning shift, completing 53 laps on his final morning in the car before Melbourne.

The Finn's total lap count of 628 across the eight day winter programme is the highest of any driver

“I got in a reasonable amount of laps on my last morning in the car and leave testing feeling confident and ready to race. I feel that as a team we have been able to improve how we work together, that we have a great spirit and real will to win,” he said. “It's been so nice over these past two weeks to see how we operate as a group, both on and off the race track. Thanks to everyone in Brackley and Brixworth for creating this beautiful package. I hope we can extract the maximum from it straight from the word go in Melbourne.”

“We've been testing lots of things, so it's going to take a long time to analyse everything that we've done. I've had a massive learning curve over these eight days and that will continue but I can't wait for the start lights to go out in Melbourne”
