Mercedes juniors in F1 'on merit'

Mercedes reserve Wehrlein, who last year became the youngest DTM champion, was announced as a Manor driver earlier this week.

GP3 champion Ocon will perform reserve role duties for Renault's new works outfit as well as contesting the DTM season with Mercedes.

The financial strain on the grid's smaller teams has led to a number of them signing drivers who bring substantial sponsorship backing.

Mercedes boss Wolff said: "It is very pleasing to see young drivers earning their spot in Formula 1 on merit and to see that talent is being rewarded by the system.

"Pascal and Esteban have proven themselves to be amongst the top young drivers out there - and both come into 2016 as champions of their respective series.

"But they still have plenty to learn and they will be staying humble, with their feet on the ground.

"This is an important year for them and we will be following their progress with great interest, while also looking to expand our junior programme.

"We're delighted that Pascal and Esteban will tackle a fresh set of challenges in 2016.

"Our aim is to build their experience in the best possible environment and, following positive discussions with our counterparts at Manor and Renault, it became clear that their respective Formula 1 programmes presented ideal opportunities to achieve that."
