Mercedes in, Renault out, at Williams F1

 Mercedes-Benz has won a contract from the Williams F1 Team for a long-term engine partnership for the 2014 Formula One World Championship season onwards. 

Under the agreement, Williams will be supplied with a Mercedes-Benz Power Unit (an internal combustion engine with an Energy Recovery System) by Mercedes AMG High Performance Powertrains (HPP) in Brixworth, UK. Williams will continue to manufacture its own transmission. 

The 2014 regulations have set the sport's engineers the challenge of completing a 300km race distance on a fuel load of 100 kg.
