Nico Rosberg kept the Mercedes on top of the time sheets for the second consecutive day in in Formula 1 testing in Bahrain, and setting the fastest time of the week while rival Red Bull continued its miserable pre-season.
The three-time grand prix winner became the only driver to break into the 1m33s with a blistering set of short runs on Pirelli’s soft tyre in the morning before completing a race run of more than 50 laps in the afternoon.
Meanwhile, Red Bull managed just 15 laps with Daniel Ricciardo as the team encountered yet more problems with its troublesome new car.
The team parked the RB10 early with software and mechanical issues and spent much of the afternoon working furiously on the car in the garage.
