2005 Formula One World Championship


The 2005 FIA Formula One World Championship was the 59th season of FIA Formula One motor racing. It featured the 56th FIA Formula One World Championship, contested over a then-record 19 Grands Prix. It commenced on 6 March 2005 and ended 16 October.
Fernando Alonso and the Renault team won the World Drivers' and World Constructors' championships, ending five years of dominance by Michael Schumacher and Ferrari since 2000 and also ending nine years of Ferrari, McLaren and Williams dominance triopoly since 1996. Alonso's success made him the youngest champion in the history of the sport, a title he held until Lewis Hamilton's 2008 title success. Renault's win was their first as a constructor. Alonso started the season off strongly, winning three of the first four races and his title success was in little doubt. He sealed the title in Brazil with two races left after a controlled third-place finish. Alonso's championship was also the first for a Renault-powered driver since Jacques Villeneuve's championship in 1997.
Alonso and Renault had to contend with the pace of the resurgent McLaren team with lead driver Kimi Räikkönen outshining teammate Juan Pablo Montoya, who came highly regarded from his time at Williams. Räikkönen won seven races like Alonso but would have won more if not for a series of reliability issues, resulting in qualifying engine change penalties and retirements from the lead on three occasions. Nevertheless, Räikkönen grabbed the headlines winning from near the back of the grid in Japan, passing Alonso's Renault teammate Giancarlo Fisichella on the final lap. Reigning champions Michael Schumacher and Ferrari had a poor season by their standards, with Bridgestone unable to compete with Michelin after the tyre-change ban that only affected the 2005 season. Their only win came when Michelin deemed their own tyres unsafe after several incidents in the oval turn at Indianapolis. As a result, only the six Bridgestone cars took part. Schumacher just held on for third in the Drivers' Championship, in spite of the superior pace of McLaren, underlining the disappointing season Montoya had. The Colombian missed two races early on due to a tennis injury. He then won three races, showing glimpses of pace, but was well beaten by his teammate Räikkönen in the championship.
The 2005 season was the last before the Minardi, BAR and Jordan teams were taken over by new owners and changed names to Toro Rosso, Honda, and Midland respectively in the season. The former Jaguar team was sold from Ford to Red Bull GmbH and made its debut as Red Bull Racing during the 2005 season.

Teams and drivers

The following teams and drivers were competitors in the 2005 FIA Formula One World Championship.
  • All engines were 3.0-litre, V10 configuration. 2005 was the final year of this engine formula.
  • No Michelin-shod cars participated in the United States Grand Prix for safety reasons, leaving just six cars on the grid at the start of the race.

    Free practice drivers

Five constructors entered free practice only drivers over the course of the season. Sauber Petronas were also eligible to enter a free practice driver, but elected not to do so.
The 2005 Formula One calendar featured one new event, the Turkish Grand Prix.

Calendar changes

  • With the Brazilian Grand Prix being run in late September, the Chinese Grand Prix became the final race of the season.
  • The Turkish Grand Prix was added to the calendar after the Hungarian Grand Prix on 21 August.

    Regulation changes

For a time there existed a distinct possibility that some teams would be running three race cars per Grand Prix: fewer than 10 teams, or 20 cars, starting on the grid would have resulted in some teams running three cars, under a term in the Concorde Agreement. By the first round of the season, there were ten teams, as Red Bull completed their takeover of Jaguar and were ready to race in Australia. Minardi, which initially received an injunction allowing them to compete despite their cars' non-conformity to new 2005 technical regulations, later modified their cars to adhere to 2005 regulations.

Technical regulations

  • A major change in 2005 was the outlawing of tyre changes during pit stops. Now a driver had to use one set of tyres during qualifying and the race itself. The reason for this rule change was to motivate the teams to select harder tyre compounds with less grip, reducing cornering speeds, which was intended to improve safety. Tyre changes were allowed for punctures and for wet weather, under the direction of the FIA. The FIA had to post a "change in climatic conditions" notice in order for tyre changes to occur normally as a force majeure. After Kimi Räikkönen's disastrous accident at the Nurburgring when his suspension collapsed after a flat-spotted tyre ripped the carbon fibre suspension apart, team principals and the FIA agreed that a single tyre change per car could be made without penalty, provided it was to change a tyre that had become dangerously worn like Räikkönen's had. Preserving a single set of tyres for the entire race became a new challenge for drivers; the challenge for tyre manufactures was to produce more durable, long-lasting compounds. Michelin-shod runners had a distinct advantage over their Bridgestone counterparts.
  • Formula One engines had to last two race weekends, double that demanded by 2004 regulations. A driver who needed to change an engine was subject to a 10-place grid penalty for the race. Designed to limit revs and power outputs demanded by greater reliability, this regulation was also a cost-cutting measure for engine manufacturers. After the initial race of the season, the FIA acted to close a loophole in this new regulation exposed by BAR, who deliberately pitted their cars rather than finish the race.
  • The technical aerodynamics regulations were modified to improve competition, especially for cars travelling in another car's air flow wake in order to overtake. By changing the size and placement of both front and rear wings, as well as requiring higher noses, the new rules attempted to reduce downforce by roughly one-quarter, but teams developed other chassis innovations to reclaim much of that "lost" downforce, which made following another car even harder than the previous season. Front wings have been lifted by, to reduce downforce, while the rear wings have been brought forward relative to the centre line between the rear wheels.
  • This was the final season in which the 3.0-litre V10 engine configuration was used by all teams. New changes in the technical regulations saw a 2.4-litre V8 engine configuration being introduced by the FIA for the 2006 Formula One season; however, the FIA granted an exemption for teams who were unable to re-engineer or could not afford a V8 engine in time for 2006. Budget or resource-limited teams were allowed to run a rev-limited 3.0-litre V10. Ten of the eleven teams ran with a conventional 2.4L V8 for 2006, with the exception of Scuderia Toro Rosso, who continued and were permitted by the FIA to use a rev-limited Cosworth TJ2006 3.0L V10 powerplant.
