The German came under fire after the season-ender in Brazil last November when 23-year-old Hamilton passed him for fifth place in the last few hundred metres to become the youngest champion.
Had he not done so, Ferrari's Brazilian Felipe Massa would have taken the title as his country's first champion since the late Ayrton Senna.
"The target is definitely to be in front of Lewis," Glock told reporters when asked about his aims for the March 29 season-opener in Australia after the internet launch of his team's new car. "If we are in front of him and McLaren it means we will have made a good start to the 2009 season."
Glock had stayed out on dry-weather tyres on the wet track while others, including Hamilton, pitted. The gamble left him struggling for grip and helpless as the Briton scythed past on the penultimate corner. The German, who still finished a creditable sixth in that race, said the criticism in the aftermath of Interlagos had stung him but it no longer bothered him.
"We are now in 2009 and I'm focused on my job now," he said. "The fans were writing negative stuff about me and that stopped a bit now.
"But at the beginning it was not an easy situation. I mean, when you sit in the race car and do a good job and take the right decision and at the end you got a lot of negative stuff, negative emails from the fans.
"We didn't do a wrong decision and it was quite tricky to deal with that stuff," he added.
"Now I don't care about it. We have a new season and Brazil is a couple of months ago and we are focused on 2009." Toyota finished the season fifth overall, with Glock taking a second place in Hungary to equal the team's best result since their debut in 2002. Glock said he hoped to go one better this year, despite Italian team mate Jarno Trulli's determination to be the team's first winner.
