I guess that with HRT being somewhat vague about their suppliers - it took a lot of searching to find out who manufactured their chassis last year (Carbotech Gmbh IIRC), and by their own admission the F111's monocoque was heavily based on the F110 because they were behind schedule and needed to get through the crash tests last year.
As I said, though, it is thought that they
may be using this years car as a base - at the moment it is not entirely clear what exactly is going on with the design of the F112, especially following the reorganisation of their technical staff and Eeckelaert being promoted from head of aerodynamics to chief technical officer. It could well be that the team has chosen to strike out in a new direction for 2011, not just in terms of chassis design but also engine supplies (switching from Cosworth to Renault if there is any credence in the rumours - though given that they will be using Williams's 2011 gearbox in 2012 it'd be more convenient for them to retain the Cosworth engine package than having to modify the gearbox for the Renault engine).
Either way, if they are hoping to take part in testing in 2012 they will need to have the car ready a lot sooner than they've managed in the past, particularly because of the requirement for crash testing to take place before the car can test. I think the reason why some are speculating HRT will re-use part of the design philosophy of the current car, and maybe some parts, is because of the additional crash test requirements - starting from a design which is known to work may be a lot easier than working on a new design from scratch.
Couple of things Mario
- HRT are using the
2012 gearbox and KERS from Williams for the F112.
- The design of the F112 started around the Belgian GP - Geoff Willis was on the BBC Practice Session (FP2) to say the 2012 was in process, now the car is being designed by Stephane Chosse and Jose Segura Galleo it is believed it is a new design because HRT are working within normal timeframes.
Question from the Jacky Eeckelart Interview on the HRT website:-
Is there already a design for the F112?
Of course there is. The model of the car exists but it is still in evolution regarding aero bits: front wing, rear wing, barge boards, floor, diffusers…they’re still in evolution. The monocoque and nose are fixed but the purely aero elements can be built in 3-4 weeks so we can wait until end of December for them. There is a model but the final product will be seen towards the end of December.
What parts of the F111 will be used on the F112?
Probably only the steering wheel and even that will be slightly modified because of the KERS, because we need an extra function on the steering wheel for it.
What are the main characteristics of the 2012 car and what will change with respect to this year’s model?
The main area on which we have worked is the downforce of the car because there is big deficit in comparison to a standard F1 car. Downforce is what pushes the car to the track, increases the grip of the tyres, makes the car brake later, go faster through corners, etc. The biggest performance deficit is from aero and that is what we’re working on. We have also made changes to the monocoque such as making it higher in the front and narrower in the rear. We will also work on adapting the rear suspension to the Pirelli tyres, in order to achieve better balance between low speed and high speed corners.
Will the F112 use Williams’ 2011 gearbox with such a low differential? Or will it continue to use the 2010 gearbox?
We will use the Williams 2012 gearbox but adapted to the Cosworth engine because in 2012 Williams will use a Renault engine.
