The 66-year-old will name his provisional larger squad a day early and spend the following three weeks whittling it down to the 23 who will carry England's hopes at Brazil 2014.
Competition for places on the plane continues as the Premier League season nears a dramatic climax, although Hodgson hinted on Tuesday his selections were all but made.
Three ruled out of the running are Southampton striker Jay Rodriguez (knee), Arsenal forward Theo Walcott (knee) and Tottenham winger Andros Townsend (ankle), while Everton defender Phil Jagielka (hamstring) is fighting to prove his fitness in time.
Club England managing director Adrian Bevington said: "We have enjoyed an extremely close relationship with Vauxhall since they became England sponsor three years ago, and this is a fine example of that.
"This will be an important day for Roy and the players ahead of an exciting summer in Brazil. It is always a day of interest to the whole country, and we're glad we can share it with Vauxhall."
Hodgson told FIFA's official website that he would base selection on players' form over the past "two years", which has raised question marks over the possible inclusion of Everton youngster Ross Barkley.
The England coach said: "I've had a very clear idea of what I want to do with this squad for a long, long time. Certainly over the last couple of weeks I'm pretty much sure of what I want to do when it comes to the team.
"All I can do is be really clear in my mind with what I want to do as a squad and which players I want to take.
"Nothing that happens in the last four games, in terms of form, is going to affect me. I don't judge players on their last-minute form over two or three games. I'm judging them over two years."
Speaking to Sky Sports' Footballers' Football Show back in February, Hodgson suggested he would know his 23-man squad by the May date.
"We will definitely take 30 players with us when we go to Portugal, and probably keep those players until such time we play the final friendly in Peru," said Hodgson.
"But what I think I would do, is to name 23, and I will name the seven that are going with us and make it clear to them that at the moment, they are not going to be in the final 23. In that way, of course, I suppose I put my cards on the table a little bit earlier.
"We can't take 30 players. We've got to take 23 players. The 30 that I name, we have the utmost respect for those players. We like them all.
"We think they're good enough, we wouldn't be averse to having any one of the seven in our 23 but, unfortunately, a choice has got to be made."
England have been drawn in Group D alongside Italy, Uruguay and Costa Rica and kick off their campaign against Cesare Prandelli's Italy in the Amazonian city of Manaus on June 14.
According to votes cast via the Sky Sports England Squad Selector, Barkley is ahead of the likes of James Milner, Jordan Henderson and Frank Lampard in the race to make Hodgson's final squad.
