New guidelines to be launched
Formulation 1 has launched rule modifications for the 2019 season geared toward making overtaking simpler and selling nearer racing.
The modifications to the automobiles have been primarily based on analysis geared toward discovering methods of constructing it more easy for one automotive to comply with intently behind one other.
“The research indicated a probability of a constructive influence on racing and overtaking,” the FIA stated.
It quantities to a victory for the FIA and F1 after opposition from some groups.
The modifications are:
- a simplified entrance wing, with a bigger span, and fewer “out-wash potential” – ie, extra air can be directed contained in the entrance wheels moderately than outdoors them
- simplified brake ducts with no winglets
- wider and deeper rear wing
The modifications got here out of analysis being undertaken by the FIA and rights holders F1 for bigger rule modifications aimed on the 2021 season, for which the game is planning a serious overhaul of technical, sporting and monetary preparations.
However the FIA and F1 found some concepts that might be launched earlier. After asking the groups to analysis their impact, it was determined to convey them ahead.
That call was partly motivated by this 12 months’s season-opening race in Australia, the place there have been solely 5 overtaking manoeuvres all through your complete grand prix.
Opponents of the modifications identified that overtaking has at all times been tough on that observe and that subsequent races had featured higher racing.
Nonetheless, there’s an acceptance inside F1 that guidelines launched in 2017 to make the automobiles sooner and extra dramatic have made overtaking tougher.
A serious discovery of the FIA/F1 analysis was that the present entrance wings have a serious influence on the power of 1 automotive to comply with one other.
These wings create a so-called “out-wash” impact, the place the air off the entrance wing is directed across the outdoors of the entrance tyres for optimum aerodynamic downforce.
It was found that this out-wash impact had a dangerous impact on the best way the air reacted with the automotive behind, lowering its potential to create downforce. With much less downforce, the automotive behind has much less grip, can’t go as quick via the corners and due to this fact the motive force struggles to get shut sufficient to overhaul.
The thought behind the rule modifications is to make sure the automotive in entrance creates much less disturbed air – by eliminating out-wash from the entrance wing by simplifying its end-plates – so the automotive behind can comply with extra intently.
The transfer was welcomed by the Grand Prix Drivers’ Affiliation. Chairman Alex Wurz stated on Twitter: “It is a success for F1 and the GPDA! The drivers’ physique has been lobbing this course since years! Thanks Ross (Brawn) and co for listening and getting this shifting!”
Brawn is the previous Mercedes F1 group boss and Ferrari technical director who’s now the top of motorsports for F1 rights holders Liberty Media. It was work by a bunch he set as much as research a future course for the foundations that has led to those modifications.
