Nico Rosberg has given team-mate Lewis Hamilton a wake-up call following the German’s winning spree at the tail end of the season, according to Mercedes technical chief Paddy Lowe.
Whilst Hamilton won ten of the opening 16 races, Rosberg went on to win the final three in dominant fashion, and even claimed six consecutive pole positions.
That has given Hamilton a lot of work to do over the winter to understand why he’s suddenly lost his advantage.
“I think Lewis has been given a bit of a wake-up call in the last three races with Nico absolutely on top form,” Lowe said on Monday.
“That’s given Lewis a bit of an uncomfortable winter.”
Lowe continued to praise the job the team have done, in particular their two drivers whose performance he described as faultless.
“What Lewis and Nico do is absolutely tremendous,” he added. “The team produced a fantastic car and a fantastic power unit and what Lewis and Nico have done to exploit that has also been tremendous.
“They do an amazing job and the results this year show an incredibly low error rate from the drivers.
“I’ve worked in the business a long time and know the greatest make mistakes. Those two haven’t this year and that is credit to them.”
