Nico Rosberg, MercedesNico Rosberg and Tonio Liuzzi have been given the green light to race in the Japanese Grand Prix despite failing to set a time in qualifying.

Mercedes driver Rosberg was unable to complete a lap after being hit by a hydraulic problem early on. He will start from 23rd position.

"On my first lap out in Q1, the team advised that I had a problem and asked me to come back into the pits," explained Rosberg. "We tried to fix it in time for me to complete a lap, however the hydraulic systems are quite complicated and there just wasn't enough time. So for the race, I have a promising strategy with all the new tires that I have! But seriously, I will push and try to get into the top 10. That will be my aim tomorrow."

HRT driver Liuzzi also suffered technical issues that prevented him from running in Q1. Although the Italian has not set a time a time within the 107 percent all weekend, stewards have allowed him to race on Sunday.
