The FIA today confirmed an S2000 based future for the WRC, which is thought to include a kit of a control turbocharger, rear wing and other small parts costing in the region of £25,000. The statement released today, from the December World Motorsport Council meeting, failed to give much explicit detail on the new formulae.
The statement from the FIA reads:
"As already announced, the 2010 World Rally Car will be S2000 based. However, the removable kit, already adopted by the WMSC, will be redefined with no electronic benefits, or similar upgrades, to ensure cost reductions. The new S2000-based World Rally Car will only be permitted for use on World Rally Championship events.
The FIA Production Car World Rally Championship will be retained for Group N cars, including the existing S2000 car."
