Nico Rosberg completed a sweep of Thursday’s two practice sessions for the Monaco Grand Prix. With a little more than an hour remaining in the second 90-minute free practice session, Rosberg dropped in the weekend’s first 1:14 lap with a lap of 1:14.759 around the streets of Monte Carlo.
Lewis Hamilton made it a Mercedes 1-2 for the W04s, albeit some three tenths of a second in arrears of Rosberg. Fernando Alonso was third ahead of his Ferrari teammate Felipe Massa and Mark Webber’s Red Bull.
Rosberg set his fastest time on Pirelli’s supersoft compounds. During the broadcast, NBC Sports Network Formula One pit reporter Will Buxton noted Rosberg was using up his rear supersofts too much, and they were “heavily fried” at one point. On the softs, Rosberg appeared to have an even greater gap to Hamilton. If the Mercedes don’t get into tire degradation trouble as they have tended to do this year, they should emerge as favorites for the rest of the weekend.
Behind the top five, the Lotus pair of Kimi Raikkonen and Romain Grosjean were next, each still within one second of Rosberg with Jenson Button, Sebastian Vettel and Paul di Resta in the top 10. Vettel, though, set his fastest lap of the day on the soft tire, so he hasn’t yet shown his full hand.
Grosjean’s session was truncated after 30 minutes following a heavy shunt on the exit of Sainte Devote, Turn 1 at Monaco. He locked up his right front supersoft tire on entry, bounded over the kerbs and into the barriers. His car was airlifted out of the spot by crane, quite high above the track, giving onlookers a good view at the floor of the Lotus E21.
The session was red flagged shortly thereafter, but not due to Grosjean’s accident. Kerb damage at Turn 13 caused a four-minute session interruption.
Down at the rear of the grid, Jules Bianchi brought Marussia back ahead of Caterham, and in the process, was close to both Toro Rossos and Valtteri Bottas’ Williams. Bianchi, in 19th, was within eight tenths of the Toro Rosso pair of Daniel Ricciardo and Jean-Eric Vergne, and six tenths adrift of Bottas’ Williams.
