Nico Rosberg made no secret of his disappointment after being sidelined by an issue during second practice for the British Grand Prix on Friday afternoon.
Rosberg arrived at Silverstone leading the Formula 1 drivers’ championship, but with Mercedes teammate Lewis Hamilton just 11 points behind, the German knows his advantage is far from secure.
Rosberg finished first practice just three-hundredths of a second shy of Hamilton at the top of the timesheets, but was unable to complete a lap in FP2 due to an issue on his W07 Hybrid car.
“I had a good morning session. It looks like we are quickest out there and that it will be a good battle between me and Lewis,” Rosberg said.
“It’s a shame that I wasn’t able to have a run in the afternoon, but I’m sure we can fix the problems by tomorrow morning.
“I will see what Lewis learned today and try to adapt this for tomorrow and Sunday.”
Team technical boss Paddy Lowe said that Mercedes was wary of sending Rosberg out and losing one of his engines, with teams being limited to just five in a season.
“It became clear shortly before FP2 began that there was a water leak on Nico’s car,” Lowe explained.
“We were optimistic of a quick fix initially but, after further checks, we opted against running the risk of losing an engine from the pool.
“We will be looking into that overnight to understand what happened and our apologies to Nico for losing him some important running time this afternoon.”
