The BMW WilliamsF1 Team today announced that Nick Heidfeld will drive alongside Australian Mark Webber for the 2005 season.
After weeks of uncertainty, the team announced its decision at the unveiling of its 2005 car, the FW27, in Valencia.
Heidfeld had been up against Brazilian Antonio Pizzonia for the best seat still available on the starting grid.
"We did a lot of testing to make the choice. It was a very difficult choice in the very last minute", commented BMW WilliamsF1 Team Principal, Frank Williams. "A very close call."
The decision gives Heidfeld, who raced for Jordan last season after spells at now-defunct Prost and Sauber, a real chance of winning races with a team that triumphed in the last grand prix of 2004.
"It's fantastic to finally have the chance of being part of a World Championship team. It's definitely the big step I hoped for in the last couple of years," said Heidfeld.
Antonio Pizzonia will continue to support the team's efforts as official test and reserve driver in 2005.
"Quite obviously I'm quite disappointed, but I'm still quite young. Yet I'll do my very best to help the team in the championship", he said.
