Glock debuted for Jordan in 2004, and thereafter rebuilt his career in America's Champ Car series and GP2.
"I have tested quite regularly (since then) so I expect it will take very little time for me to get back in the groove," he said. "I have been lucky enough to race and succeed in several different championships in my career but my goal has always been to become a full-time formula o race driver," Glock added.
Toyota's statement on Monday did not mention who his teammate will be. Jarno Trulli has a contract that includes 2008. (GMM)
