F1 notes: Rosberg, Hamilton top British GP practice; Wolff kaput
SILVERSTONE, England (AP) — Lewis Hamilton topped the times ahead of Mercedes team-mate and series leader Nico Rosberg on Friday in second practice at the British Grand Prix.
The 29-year-old Briton, champion in 2008, clocked a best lap in 1 minute, 34.508 seconds to outpace German Rosberg, who leads him by 29 points in the championship, by 0.228 seconds.
But on a warm and windy day Hamilton then stopped on track with an engine problem that hit his preparations for Sunday's key race, which he has targeted for victory in a bid to reboot his title challenge.
Two-time champion Spaniard Fernando Alonso was third quickest for Ferrari.
Alonso was seven seconds down on the pace-setters, but ahead of the two Red Bulls of Australian Daniel Ricciardo and defending four time champion German Sebastian Vettel.
They were both more than a second behind on sheer one lap pace, but improved their overall pace on the long runs in the final stages of the long afternoon session.
Hamilton came to a halt on track with a serious engine problem an hour into the 90-minute session when he stopped out on the circuit. "Engine stopped," he told the team by radio. "Says engine kill, no shifting."
He managed only 14 completed laps compared to Rosberg's 35, but will have access to the championship leader's data after the session.
Rosberg leads Hamilton by 29 points in their personal duel for the title after eight of this year's 19 races.
Finn Valtteri Bottas was sixth fastest for Williams—having missed the morning session when his car was briefly run for just three laps by Susie Wolff, the first woman in 22 years to take part in a Grand Prix—ahead of Briton Jenson Button in the leading McLaren.
Danish rookie Kevin Magnussen was eighth fastest in the second McLaren ahead of Finn KimiRaikkonen of Ferrari and 10th placed Frenchman Jean-Eric Vergne of Toro Rosso.
Rosberg had topped the times Friday morning ahead of Hamilton in an opening session in which the main focus was on the luckless 31-year-old Wolff.
The Scot at least became the first woman to take part in a Grand Prix weekend since 1992, even if she lasted only three laps before her engine failed - and only a few minutes later her Williams team-mate Brazilian Felipe Massa crashed out of the session.
Meanwhile, Wolff's bid ended prematurely on Friday when she lasted only three laps before her engine failed—and only a few minutes later, her Williams teammate Felipe Massa crashed out of the session.
"It was a really tough day, but that's Formula One sometimes," Wolff said. "We had an oil pressure problem which cut the engines—the guys are looking at getting it fixed for free practice two."
Wolff idled to a halt after only three timed laps in the opening practice for the British Grand Prix on Sunday.
"The engine has gone—terminal," she was told by her race engineer.
"I want to say a huge thank you for all the support," she said. "It means a lot, and really helps. It was wonderful. Although there's been a lot of media around this run, once I had put the helmet on that was the best feeling. And as soon as I had left the pit lane, everything felt good. Unfortunately it was a short run, but now I'm going to look forward to Hockenheim (the German GP in two weeks)."
