Japanese GP: Lewis Hamilton leads Mercedes one-two in FP1

In a 'two by two' top eight in which the driver pairings from Formula 1's leading four teams lined up next to each other, Mercedes secured a one-two ahead of the Red Bulls.

Rosberg put in his quick lap, a 1m34.487s, first but it was usurped shortly afterwards when Hamilton went 0.330 seconds quicker.

Sebastian Vettel was the fastest Red Bull in third, albeit 0.611s off the pace.

His team-mate Mark Webber took fourth, followed by the Ferraris, and Lotuses, with Felipe Massa and Romain Grosjean outpacing their respective team-mates.

The symmetry was broken at the foot of the top 10, where Daniel Ricciardo put his Toro Rosso between the McLarens of Sergio Perez and Jenson Button late on.

Several drivers further down the order ran into trouble.

Pastor Maldonado had to park his Williams at Spoon after spinning when his left rear wheel flew off.

Both Jules Bianchi and Giedo van der Garde crashed at Degner. While the Caterham only just nudged the tyres, Bianchi's Marussia will need a more substantial rebuild following his early crash.

Despite only managing eight laps on his Suzuka debut, Bianchi was a second clear of Marussia team-mate Max Chilton and was only narrowly pipped to rear quartet honours by Caterham's returnee practice driver Heikki Kovalainen.
