Takuma Sato

In 2002 Sato graduated to Formula One with the Honda-powered Jordan team, and was paired with Giancarlo Fisichella. His low point was a tremendous crash in Austria, caused when Nick Heidfeld lost control of his Sauber under braking and hit the side of Sato's car, punching a hole in the side of the cockpit.[8] Throughout he showed flashes of speed but also wild driving, nevertheless the team's faith in Sato was repaid by a fine drive to fifth at his home Grand Prix in Suzuka.

With Honda's focus shifting solely to British American Racing for 2003 Sato joined the Brackley-based outfit as a test driver. For the final round in Japan, Sato replaced Jacques Villeneuve and scored the second points finish of his career with sixth place, after a battle with Michael Schumacher. He was signed to race full-time in 2004. During the 2004 season, Sato qualified four times in the top-three, including a front row start and an overall lap record at the European Grand Prix.[6] Sato's aggressive driving style paid dividends at the United States Grand Prix, where, after the team did not pit under safety car conditions, Sato fought back with some daring overtaking moves to score his first podium finish, and the first for a Japanese driver since Aguri Suzuki at the 1990 Japanese Grand Prix. Reliability issues caused him to retire six times, but he scored points in nine of the 11 races he completed to finish eighth in the championship with 34 points, the best-ever result for a Japanese driver in Formula One.[2] His efforts helped BAR-Honda to finish second in the Constructors' Championship.

Sato was retained by BAR-Honda for the 2005 season, but the 2005 car was not as close to the front of the pack as the previous year's design. Sato missed the Malaysian Grand Prix with illness, and both drivers were disqualified from the San Marino Grand Prix and the entire team banned from the two subsequent races for using cars which were underweight when all fuel was removed. The Court did not find that this was deliberate. Sato's season never recovered from that point, and he ended the season with eighth-place at the Hungarian Grand Prix as his only points finish, despite qualifying seven times in the top ten.[9] Sato was not re-signed for 2006, despite Honda taking full control of the team.

Sato joined the new Super Aguri F1 team for 2006, run by Japanese former driver Aguri Suzuki. The new outfit was in effect a Honda B-team but ran the first half of the season with a modified version of a 2002 Arrows A23 chassis. Nevertheless, Sato's reputation improved thanks to his professional attitude and competitive spirit. The team introduced a new car, the SA06 at the German Grand Prix and by the end of the season Sato was outpacing the Midland cars. At the season finale in Brazil Sato finished tenth just two places short of a points finish and comfortably ahead of both Toro Rossos and the Spyker MF1s.

For 2007, Super Aguri ran a reworked version of the previous year's Honda RA106 chassis. Their performance improved drastically as Sato made it through to Q3 at the Australian Grand Prix. He then scored the first point for the team at the Spanish Grand Prix. At the Canadian Grand Prix, Sato finished sixth after having a race that had seen him move from the middle of the grid to a high of fifth, passing Ferrari's Kimi Räikkönen before a pit-stop error dropped him back to eleventh. He moved up five places in the last 15 laps, passing Toyota's Ralf Schumacher and then on lap 67 the McLaren-Mercedes of Fernando Alonso; the latter pass was met with cheers around the track and received him the "Overtake of the Year" award from F1 Racing magazine.[10][11]

Financial problems began to affect the team in the off-season and the squad only just made it to the opening round of the 2008 season in Australia. The team used a modified Honda RA107 chassis, which was launched just before the first Friday Practice session that weekend. A transmission issue in Australia ended an opportunity to score points in a race of attrition, and 13th in Spain turned out to be Sato's best result of the season. Due to the financial struggles, Super Aguri withdrew from Formula One after the Spanish Grand Prix, leaving Sato without a drive after four races in 2008.

In late 2008, Sato took part in tests at Jerez with Scuderia Toro Rosso, to become a candidate to fill the seat vacated by Sebastian Vettel. He was competing against former Toro Rosso driver Sébastien Bourdais and Red Bull Racing test and reserve driver Sébastien Buemi for one of the two race seats.[12] He first drove on 18 September, more than four months since Super Aguri's withdrawal, and tested for the team again for two days in November, setting the fastest time on the 17th,[13] 3 tenths ahead of Buemi, and proceeded by setting the second-fastest time on the 18th.[14] The race seat was eventually given to Bourdais, and in March 2009 it was announced that Sato would not be the reserve driver for the Red Bull team.[15]

Sato visited the Indianapolis 500 in May 2009. He signed with KV Racing Technology to drive in the 2010 IndyCar Series season[16] finishing in 21st place. He signed for the same team for 2011 and improved his form, scoring three top 5 finishes and two pole positions during the season to finish 13th.[17]

At the 2012 Indianapolis 500, driving for Rahal Letterman Lanigan Racing, Sato chased Dario Franchitti to the finish making a move for the lead and the race win at the first turn of the last lap. While not successful, Sato was respected by Indianapolis 500 fans for "going for it" on the last lap.

Sato at the 2013 Grand Prix of Long Beach, where he took his first IndyCar win and became the first Japanese driver to do so.

For 2013, Sato joined A. J. Foyt's team, driving the No. 14 car vacated by Mike Conway. In the third race of the season at Long Beach, Sato scored his first IndyCar win, in his 52nd start in the series, making him the first Japanese driver to win an IndyCar race.[18] He then scored six top five finishes, including two podiums and two pole positions, until he left the team at the end of 2016.

Sato joined Andretti Autosport for the 2017 season. He went on to become the first Japanese driver and first non Caucasian driver to win the Indianapolis 500.[19] After the 500 win, he went on to win a pole at the Dual in Detroit on Belle Isle. He also ended up winning another pole at Pocono Raceway in August.

On 26 August 2017, it was reported that in 2018, Sato would rejoin RLL to drive the 30 car with Graham Rahal as his teammate as Andretti Autosport considered a move to Chevrolet in 2018. That move by Andretti subsequently did not happen. After numerous weeks of bad luck including crashing early in the Indianapolis 500 and wrecking early at Pocono and a failed pit strategy at Gateway, Sato played the strategy right and held off Ryan Hunter-Reay in the IndyCar return to Portland, winning his third career race and his first on a permanent road course, doing so from 20th starting position. Sato started off his 2019 season with a win in the third race at Barber Motorsports Park; he started the race from pole position and ran away to the finish. Sato won later in the season at World Wide Technology Raceway at Gateway.

On August 23, 2020, after qualifying on the outside of the front row for the 104th running of the Indianapolis 500, Sato won the race for a second time.[20]

On 14 June 2012, Team Mugen announced that Sato would race with the team in the last three rounds of the 2012 Formula Nippon season.[21] He also raced with Team Mugen in the opening round of the renamed 2013 Super Formula season, and later in the year returned to the team to compete in the last three races of the season; he scored his first points with an eight-place finish in the season finale.

In November 2013, Sato became a test and development driver for the FIA Formula E Championship.[22] In September 2014, Sato joined his former Formula One team Amlin Aguri to race in the first-ever Formula E race, the 2014 Beijing ePrix, replacing the team's regular driver Antonio Félix da Costa as he could not participate due to other commitments.[23] Sato scored two points after he set the fastest lap of the race with a time of 1:45.101, but had to retire from the race with mechanical issues. As it was Sato's only Formula E race, he became the only driver in the series' history with a 100% fastest lap record.[24]
