Lewis Hamilton forced to miss the final day of testing in Barcelona after problem with his Mercedes
Former world champ did admit the latest car is the fastest he's driven in Formula 1

LEWIS HAMILTON missed the final day of testing in Barcelona after a problem with his Mercedes.
The three-time Formula One world champion, 32, was set to drive at the Circuit de Catalunya yesterday.
But an electrical fault kept the Brit on the sidelines although Valtteri Bottas, his new team-mate, drove nine laps after the problem was fixed.
Hamilton tweeted: “I’ve decided with the team not to drive today as I wouldn’t have learned much.
“Shame, but it’s been a great few days. The guys have done an awesome job. Can’t wait to be back in the car next week!”
