Force India hope to be challenging for Formula One race wins by 2010 after announcing a five-year partnership with McLaren-Mercedes.
The deal, presented to factory employees by principal Vijay Mallya and McLaren's Martin Whitmarsh, will see the team use the same engines and gearbox as those in world champion Lewis Hamilton's McLaren.
The team will also have access to McLaren's network of suppliers and operational support.
Force India failed to score a point this year and Mallya carried out a major management restructuring last week.
Despite the deal, both parties stressed that Force India will remain an independent constructor, and is not about to become a 'B' team.
Formula one's kingpin Bernie Ecclestone has already declared plans to stage an Indian Grand Prix in 2011.
