It appears that HRT have published a 3D computer generated model of their 2012 car in their website. The car has already failed some of its crash tests, which means that HRT face a race against time to have it ready for the 2nd (and final) Barcelona tests.
Edit (a few hours later): Andrew Benson is reporting that he contacted HRT and this is the old car (2011). It appears that HRT amuse themselves by building pages for the new car, naming it F112, and then putting pictures of the old one (since, apparently, very few people are actually busy with building a new car for the 2012 season). Unless they are planning to race the old car, in which case this is both the F111 and the F112, all rolled into one. Seriously, what are these guys thinking?
