SCOTSMAN Di Resta and German Adrian Sutil helped take the wraps off the new car at the team’s Silverstone base.
“We’ve got high aims of finishing in a good constructors’ championship position and I know that I’ve got to play my part in this,” Di Resta said.
The team will assess the new car’s performance at the second winter test, which begins in Jerez today.
Force India finished eighth in the team standings last season, with Sutil’s best performances coming in Malaysia and Spa, where he finished fifth.
The likeable Di Resta, whose promotion has been expected for some time, has plenty of reasons to feel confident about his first season in F1.
At the presentation of the VJM04, the team were united in their determination to build on that foundation in the coming season.
“This year there is even more to be optimistic about,” said team owner and principal Vijay Mallya.
“We’ve got three race drivers that are hungry to take the next steps in their careers, whether that be points, podiums or wins.”
Di Resta signed for Force India in January after winning the team’s support last season as their reserve driver.
Sutil, who is entering his fifth season in F1, added: “The progress the team has shown over the past two years has been very impressive and what I’ve seen in the factory and at the wind tunnel over the past weeks indicates that the rate will continue this year.
“I feel very good and confident. I just missed out on the top 10 last year in the drivers’ standings – I’m pretty hopeful I can get in there this season.”
Force India have the experienced Nico Hulkenberg waiting in reserve and the German will take part in the majority of Friday (February 11) practice sessions.
Despite an impressive rookie season, Hulkenberg, who took pole at last season’s Brazilian Grand Prix, was released by Williams in favour of Pastor Maldonado, whose presence in the team is tied to a multi-year, multi-million-pound sponsorship from the Venezuelan state oil company.
The 2011 car has been overseen by new technical director Andrew Green after his predecessors James Key and Mark Smith both left for rival teams within the last year.
A raft of rule changes for the new season means design departments have had to manage the return of the Kers power-boost device, the introduction of a moveable rear wing and the removal of the double-diffuser and the F-duct aerodynamic aid, as well as the difficulties of designing a car to suit the Pirelli tyres.
