The F111 is an evolution of the Dallara designed F110 which competed in the 2010 Formula One season. Although Gary Anderson described the F110 at its inauguration as "neat and tidy", it was in fact an underdeveloped package without any testing due to financial rumblings within the team.

Unfortunately, the story of the F111 is rather similar. Financially the team is a little bit better organised, and respected designer Geoff Willis was taken on board as a consultant to try and improve the existing chassis.

Again for financial reasons, the team chose to keep the same monocoque to be able to skip some of the crash tests. When the car was then finally shipped to the final pre-season test at Barcelona, HRT called off the single testing day as its dampers got stuck in customs. As such, the F111 starts the season with 0 testing kilometers, just like the F110.

Colin Kolles said at the launch: "The F111 represents a significant step forward for Hispania Racing. We have made a big improvement for our second season in Formula 1 and what you see in our new car confirms Hispania Racing´s commitment to F1."

The team's technical director commented: "Starting the programme to develop the F111 has been an enormous challenge. The group of engineers working from many separate locations had to produce the 2011 HRT chassis to meet the new regulations, package the Williams LG14 transmission, design all new rear suspension to suit and develop a complete aero package. Given the tight time frame, I am very impressed with the result and the enormous efforts everyone has put in to achieve the objective. However we have to be realistic in our expectations of performance; this is very much a baseline car which the team must develop in 2011."
