SILVERSTONE, England (AP) — Lewis Hamilton said he would gain very little from access to Mercedes team-mate Nico Rosberg's data after the driver topped the times but then stopped on track in Friday's practice for the British Grand Prix.
The 29-year-old Briton, champion in 2008 and desperate to win this Sunday's race to reboot his title bid this season, missed the final half hour of the afternoon's second free session while Rosberg ran without problems.
Hamilton, 29 points behind German Rosberg in the title race, had an engine problem that left him stranded out on the circuit.
Amid speculation that the two rivals and team-mates share little data within the team, Hamilton made clear that full access to Rosberg's information would be of little use.
Hamilton said: "The long run data doesn't really help in the sense that we drive so differently. It doesn't help you in the sense of understanding how the tires are lasting, and whether you need to put the car into more understeer, or oversteer, whether you need to move the brake balance, or which corners you want to lift and coast.
"All those different things you need to practice. It makes it really hard, but I'll be OK. I don't know why things happen to my car so much. We'll fix it, but I really needed a long run. Now I don't know what the car is going to feel like for the race."
Rosberg played down suggestions that the two were not sharing their information. "We have to think about the team in the first instance and everything is open," he said.
"We share everything. We're dominating the sport because we've managed to work together really well. Of course, there comes a point where I am fighting him and at that point I will try to keep certain advantages, as he will too.
"We always try to keep an advantage over each other, but never compromising the team as a whole. It's a fine line."
