The Williams motor racing team will keep an unchanged lineup of Germany's Nico Rosberg and Japan's Kazuki Nakajima for next season's Formula One championship.
Williams say Formula One's technical regulations changing considerably continuity was a key consideration.
Rosberg, 23, was already under contract for 2009 after team founder and co-owner Frank Williams last year rejected what he called an offer of "majestic proportions" from Mercedes-powered McLaren.
But Toyota protege Nakajima, son of former racer Satoru and currently Japan's only grand prix driver, had been waiting to hear whether he would be retained for a second season.
