Will it be third time lucky for Nico Rosberg (right) in 2016? Or will his Mercedes teammate Lewis Hamilton (left) win a third successive Formula One championship?

The new Mercedes car showed no signs of slowing over eight days of winter testing Barcelona, putting an impressive 1,294 laps on the clock -- the equivalent of more than 19 races.

Former F1 race-winner Mark Webber tips Hamilton to be "dangerous" if he shakes off his post-2015 title success hangover.

Rosberg -- Webber's teammate during his 2006 rookie season at Williams -- won the last three races of 2015 after Hamilton had clinched the third drivers' championship of his career.

Webber believes Hamilton "backed off a sniff, two or three percent" after clinching his second successive title at the U.S. Grand Prix in Austin, Texas.

As well as those three wins, Rosberg claimed six pole positions at the end of last year to give him much-needed momentum ahead of the new season.
