Former Formula One test driver Maria de Villota has died at the age of 33.

Spaniard De Villota was the daughter of former F1 driver Emilio, and competed in F3, GTs, touring cars and the Superleague Formula before joining up with Marussia.

On July 3 last year, whilst testing for Marussia, De Villota was involved in a freak accident at Duxford Aerodrome that resulted in her losing her right eye.

Despite spending a month in hospital, De Villota rebuilt her life and became part of the FIA's Women In Motorsport commission.

It is understood De Villota was on a tour promoting her autobiography at the time of her death, with reports in Spain stating she was found in a hotel room in Seville.

A statement on De Villota's Facebook page, signed by her family, read: "Dear friends: Maria has left us.

"She had to go to heaven like all angels. We are thankful to God for the extra year and a half that he left her with us."

With the news breaking in the paddock in Suzuka just as the second practice session for the Japanese Grand Prix had concluded, Marussia declined to comment.

A spokesperson said: "We have only just heard the news and we are awaiting to find out more.

"We will comment at an appropriate time. If the reports are true, then it is obviously very tragic."

A variety of messages were, however, appearing on Twitter.

A message from Sauber F1 team read: "We are shocked to hear about the death of Maria de Villota. Our sincerest condolences and sympathy to her family for this tragic loss."

Caterham F1 Team added: "We'd like to echo the thoughts of the whole paddock and express our deepest condolences on the news of Maria de Villota's passing. RIP."

Former F1 driver Karun Chandhok wrote: "Tragic news about Maria de Villota. Sat next to her just a couple weeks ago at FIA Drivers Comm meeting. Was doing a lot for women in racing."

Sahara Force India added: "Very sad news coming from Spain about brave Maria de Villota passing away. Our thoughts are with Maria's family and friends in this moment."
