The FIA’s more accessible and more environmentally friendly Rally1 category continues to gather momentum ahead of its planned 2022 roll-out.
While the introduction of this exciting category will mark the completion of the World Rally Car era, as the top tier of the FIA World Rally Championship, Rally1 retains the fundamentals behind the ongoing success of the WRC, but with a focus on cost management and sustainability.
Rally1 cars will continue to look and sound aggressive, bear resemblance to their road-going equivalents, while achieving performance levels as close as possible to the current World Rally Car formula.
The accessible nature of the Rally1 regulations will quickly allow manufacturers to fight for victories, while the performance parity will help to deliver strong competition between the world’s best drivers.
However, in parallel, Rally1 will also introduce sustainable technology to the WRC, with the intention of transferring key learnings and procedures to other disciplines in the future. A concept of scaling will allow for more cars to fit the regulations to maximise participation.
At the FIA World Motor Sport Council meeting in Geneva on March 6, the Technical Regulation for this new class were approved. These are the result of months of rigorous analysis and investigation by the FIA’s team of expert personnel in close collaboration with the WRC manufacturers, with every design cost required to demonstrate a tangible benefit, without losing the ethos of maintaining top-line performance.
The approved technical rules are summarised below:
Transmission:
4WD, five-speed transmission very similar in concept to the current Rally2 rules
Simple level type differential, no centre differential, only one kinematic drive train
A maximum of six transmission units per car per year permitted
Suspension:
Reduced wheel travel
Simplified dampers with reduced scope for homologation upgrades
Hubs, hub carriers and anti-roll bar designs will be simplified
Only one specification of wishbone mandated
Running gear:
Liquid brake cooling no longer allowed
Fuel tank:
Simplified shape
Aerodynamics:
Free volume bodywork area to enable aggressive design maintained
Aero effect from hidden ducts removed
Rear aerodynamic advice simplified
The working groups will continue to finalise a number of other areas of the regulations to be presented to the WRC Commission in May ahead of the June World Motor Sport Council meeting in Thailand, when ratification will be sought.
These areas relate to the fine detail of the engine regulations, hybrid technology specification and implementation following the completion of ongoing tender processes, standardised safety cell and other safety features designed by the FIA.
In addition, the FIA teams will continue to work on fuel development and the process of obtaining 2022 entry commitment from prospective manufacturers.
