2001 Technical Regulations
2001 is defined by one regulatory retreat: the FIA conceded that enforcing the traction-control ban was impossible given the sophistication of engine-management ECUs, and officially re-legalised traction control from the Spanish GP onward. The decision was controversial — a tacit admission that several teams had been breaching the ban for years — but the sport's technical director concluded detection was unreliable. Michelin returned to F1 after a 17-year absence, supplying Williams, Jaguar, Benetton, Prost and others against incumbent Bridgestone. Safety-cell front impact requirements were tightened, and an additional wheel-tether cable on each corner was mandated.
Traction control re-legalised (mid-season)
Traction control, banned since 1994, was officially re-legalised from the 2001 Spanish Grand Prix onward. The FIA cited the impossibility of reliable detection given that TC could be indistinguishable from legal engine-management maps. Teams openly developed and tuned TC systems from that point through the end of the following season. Launch control was also re-legalised but would be re-banned in 2003.
Key changes
- Traction control re-legalised from Spanish GP 2001.
- Launch control re-legalised.
Michelin returns
Michelin supplied F1 tyres for the first time since 1984, kicking off a decade of Bridgestone-vs-Michelin competition. Approximately half the grid each season split between the two. The tyre war drove large lap-time gains across 2001-2006 before Michelin withdrew at the end of 2006 after Indianapolis-2005 fallout and the prospect of a 2007 single-supplier formula.
