Manor Grand Prix Racing Limited, trading as Manor Racing MRT, was a British Formula One racing team and constructor based in Banbury, Oxfordshire in the United Kingdom. The team originally started racing in 2010 under the "Virgin Racing" name; the following year Virgin adopted Marussia as a title sponsor becoming "Marussia Virgin Racing" until being fully rebranded as the "Marussia F1 Team" for 2012.
On 19 January 2015, the administrators of Marussia announced that the auction of its cars and assets had been cancelled so as to allow a possible buy out to take place. The team collapsed in November 2014 owing around £60m, two of the companies out of pocket being Marussia's former competitors McLaren and Ferrari. The team exited administration on 19 February 2015, and was re-established as the "Manor Marussia F1 Team" after a CVA had been signed and new investment was secured to rescue the team. It was later announced that OVO Energy Owner and CEO, Stephen Fitzpatrick had purchased the team. The team retained "Marussia" as its constructor name throughout the 2015 season, also adopting a British licence. On 19 January 2016, the team announced it would be renamed to "Manor Racing".
The team competed under the constructor name MRT which stands for Manor Racing Team.
On 6 January 2017, it was announced that Manor's parent company, Just Racing Services, had been placed into administration by administrators at FRP Advisory. On 27 January, Just Racing Services collapsed after failing to find a buyer. The team closed before the start of the 2017 season. Their 2017 entry fee was returned at the end of 2017.
The team's collapse means all of the teams who joined the championship in 2010 have now disappeared from the grid. The arrival of Haas F1 in 2016 has subsequently displaced Manor and the other 2010 teams as the sport's latest entry.
