Tsuchiya Engineering is a Japanese motor racing team based in Fujisawa, Kanagawa, which competed in the GT300 class of Super GT.
A long-time Toyota-fielding team in Super GT, the team won three drivers' and teams' titles in the GT300 class, as well as two Japanese Touring Car Championship teams' titles in Division-3.
Haruo Tsuchiya (1945-2021), a former motocross rider, worked at TOMEI Automotive from 1968 to 1971 to create his own shop and team. [1] The team initially competed in local touring car races, before entering JTC, where it won the Division-3 title twice, in 1989 and 1990. [2] Tsuchiya entered JGTC in 1997 with a Toyota MR2 and won its first title in 1998, after winning five out of six races with Shingo Tachi and Keiichi Suzuki behind the wheel. [3] The following year, the team partnered with A'PEX and scored a lone win at Fuji and two more podiums to secure the drivers' title with Morio Nitta, as well as taking their second consecutive teams' title. [4]
Entering GT500 in 2000, the team fielded a Toyota Supra until 2006, before fielding a Lexus SC430 for the following two years. [5] In their nine-year stint in the category, the team scored five podiums, including their only win at Okayama in 2005. [6] At the end of the 2008 season, the team suspended its motorsport activities in 2009 due to the economic recession and the reduction of manufacturer support. [7] [2]
Haruo's son Takeshi, founded 25 Racing/Team Samurai in 2010, with his father as manager. [2] [8] Across the next four years, the team competed in Super GT until 2011, before then competing in Porsche Carrera Cup Japan, Super Taikyu and JAF Formula 4. [9] In 2015, Tsuchiya Engineering made their return to GT300 competition, with Takeshi Tsuchiya and Takamitsu Matsui driving a Toyota 86 MC GT300. [10] In the team's first full season since 2011, the Tsuchiya-Matsui pairing won at Sportsland SUGO and qualified on pole at Buriram to end the season ninth in points. [11] Retaining both Tsuchiya and Matsui for 2016, the pair scored wins at Buriram and Motegi to secure their third drivers' and teams' titles. [12] Ten days after the season-finale, Haruo was diagnosed with oral cancer, and as a result Takeshi retired from full-time racing to take over the running of the team. [2]
For the team's title defence, Matsui remained for a third consecutive season as Kenta Yamashita replaced Tsuchiya as the team's second driver. [13] In their only season together, the Matsui-Yamashita pair won at Autopolis and finished third at Sportsland SUGO to secure sixth in the teams' standings. [14] Matsui remained with the team as the sole full-time driver for the 2017 season, finishing third at Okayama and second at Suzuka alongside Sho Tsuboi as the team ended the year eighth in points. [15] [16] In 2019, Matsui remained with the team as he was joined by Kimiya Sato, as they scored a best result of fourth at Buriram and qualified on pole three times to end the year 18th in points. [17]
Ahead of 2020, the team switched to a Porsche 911, [18] [19] fielding it until 2021, scoring a best result of fifth at Motegi in the latter year, before the team switched to a self-built Toyota GR Supra. [20] [21] In their first year with the Supra, the team scored a single points finish at Sportsland SUGO, by finishing tenth, to end the year 34th in the teams' standings in a season in which they missed the second Fuji round following a testing crash at Suzuka. [22]
In 2023, at the fourth round of the season at Fuji, both Tsuchiya-ran cars caught fire, leading to both cars withdrawing from the following event and the rest of the season. [23] Tsuchiya then started a fundraiser known as the "Hopico Revival Project" in order to help the team return to racing. [24] The team returned to GT300 competition in the following year with Takamitsu Matsui and Togo Suganami, with a rebuilt version of "Hopico". [25]
Before the 2020 Super GT season it was announced that Tsuchiya Engineering would support series newcomers Max Racing, by servicing their car. [26] The partnership lasted until the 2023 Fuji GT 450km Race, where both cars caught fire and Max Racing ceased operations with immediate effect. [27] In their three-year partnership, Max Racing scored a lone win at Suzuka in 2021 and scored a best points finish of fourth the same year. [28]
