HKS (company)

HKS was formed in 1973 by Hiroyuki Hasegawa, a former engineer for the Yamaha Motor Company, and his partner Goichi Kitagawa, while the start up capital was supplied by Sigma Automotive (hence the name HKS). The company began operations by tuning gasoline engines in a dairy-farming shed at the foot of Mount Fuji. Their goal was to design and build high performance engines and components that major original equipment manufacturers could not, or would not, produce. In 1984, HKS brought in the Nara-based tuning and service shop Twin Power Co., Ltd. under the new name of HKS Kansai Service Co., Ltd. as an affiliated partner with HKS. The shop served as a service center, tuning partner, parts distributor, and R&D partner for HKS. In 2002, HKS Kansai Service became a major suspension overhaul and servicing center for HKS suspension customers. HKS Kansai Service also gained their own accolades and accomplishments in motorsport and even began developing their own aftermarket parts. In 2010, the official affiliation came to a close and the company was renamed to Kansai Service Co., Ltd. but it still maintains a good working relationship with HKS. In July 1984, HKS built a new factory in Kamiide, Fujinomiya, not far from the site of the original shop at the Mount Fuji dairy-farming shed. In April 1985, HKS built an additional factory in Kitayama specifically for muffler production for both HKS and on consignment. In 2003, the first HKS Technical Factory was established in Toda, Saitama and later another was established in Sapporo. These technical factories serve as HKS-owned service, tuning, and development centers, as well as offering the sale of select HKS complete vehicles and parts. Additionally, a dedicated HKS Service Center was also established in Kitakyushu. The company also operates three sales offices within Japan, in Tokyo, Nagoya, and Osaka. The HKS headquarters remains near Mount Fuji with its main 100,000 square foot manufacturing and R&D facility in Fujinomiya City, Shizuoka Prefecture with an international sales and distribution network spanning Asia, Europe, Australia and the Americas to support its customer base. HKS USA was reestablished in 2017 as the consolidated subsidiary HKS USA, Inc. in Chandler, Arizona. Additional subsidiary companies have been established in Cambridgeshire, England (HKS Europe) in 1996, Bangkok, Thailand (HKS Thailand) in 2001, and Shanghai, China (HKS Shanghai) in 2012. Since June 1999, HKS has been a publicly traded company, first with the Japan Securities Dealers Association, and later in 2004 on the JASDAQ Securities Exchange. HKS also gained full ownership of the metal processing and manufacturing company Nissei Kogyo Co., Ltd. in May, 2000. Nissei Industries also produces crankshafts, camshafts, cylinders, pistons, and injector parts. In 2024, HKS launched a new collaborative brand with Studie AG, a BMW-specific tuning company, named HKSTUDIE. The company specializes in manufacturing tuning parts for BMW sports cars, such as exhaust systems and coilover suspension. ==Products==

The company also undertakes contract manufacturing for clients. HKS received the ISO 9001 quality management standard certification in 2010, certifying manufacturing standards for OEM and contract clients. Additionally, the company has a division for compressed natural gas engineering, as well as bi-fuel systems that run on both gasoline and compressed natural gas. These systems are designed for usage in commercial trucks as well as road vehicles. The subsidiary HKS Aviation was launched in 1996. The company produced the HKS 700E aircraft engine along with other light-sport aircraft products, but the subsidiary has since ceased operations. The HKS IoT Connected Service division was launched in 2019 for engineering and manufacturing connected devices such as a 360° camera, sensor system, coronavirus countermeasure device, and shuttle bus safety device. The Ministry of Land, Infrastructure, Transport and Tourism approved the Shuttle Bus Safety Monitoring Device, named "MAMORU", and HKS released it on March 31, 2023. In 2021, the Ministry of the Environment commissioned HKS to join the "Battery Exchangeable EV Development and Renewable Energy Utilization Group" to aid in the development of exchangeable battery EV commercial (ExCVB) light-duty trucks. HKS began delivery demonstrations of prototypes at FamilyMart stores in November 2022. ==Motorsport==

Since the 1980s, HKS has competed in many forms of motorsports including time attack, drag racing, JTCC, JGTC, F3, D1 Grand Prix, Superbikes, plus many others. They also sponsor many racers to carry the HKS name and to become part of the HKS team. They notably have had the likes of Anthony Reid (Super Touring/JTCC), Nobuteru Taniguchi (D1 Grand Prix and time attack), Tetsuya Kawasaki (Drag racing), Akira Iida (Time attack), and Max Orido (Test driver) drive for their in-house team. Time attack and speed records Since 1983, HKS has been heavily involved in developing and racing cars for setting both time attack and speed records. In 1983, HKS developed the HKS M300, a highly tuned Toyota Celica XX with a twin-turbocharged 5M-GE engine, to set speed records. The M300 became the first ever Japanese automobile to exceed 300 km/h (186.41 mph) with a speed record of 301.25 km/h (187.19 mph) at the Yatabe proving grounds in 1983. In 1993, the HKS T-001, a modified Toyota Supra (A80), was developed for time attack and speed trials. It produced over 730 ps (720 hp), reached 344 km/h (214 mph), and set a lap time at the Tsukuba Circuit of 1 minute 1.97 seconds., lap record breaker at TsukubaIn 1995, the team began testing with the HKS T-002, a specially tuned Nissan Skyline GT-R (R33). The T-002 set the lap record at the Tsukuba Circuit at 58.71 seconds, and a 0 to 300 km/h (186.41 mph) record of 17.64 seconds at Yatabe. It also went on to win Best Tuning Vehicle at the Tokyo Auto Salon. The next HKS time attack vehicle, the HKS TRB-01 (an internal codename for "Tsukuba Record Breaker"), also known as the HKS Racing Altezza, was launched at the 2000 Tokyo Auto Salon. It was a tuned Toyota Altezza producing over 600 hp with extensive weight-saving, aerodynamic, and handling methods taken. It went on to set a new lap record at the Tsukuba Circuit of 55.85 seconds, driven by Nobuteru Taniguchi. The HKS TRB-02, a time attack Mitsubishi Lancer Evolution VIII, was developed in 2003. Taniguchi set a lap record at Tsukuba in 2003 of 55.00 seconds and in 2004 of 54.73 seconds. It produced 560ps (552 hp) out of a tuned and turbocharged 4G63. To compete in additional time attack events domestically and internationally, the HKS Racing Performer CT230R was developed in 2006. This tuned Mitsubishi Lancer Evolution IX set numerous lap records across Japan: 1 minute 42.37 seconds at Fuji Speedway, 1 minute 21.53 seconds at Tokachi Speedway, 1 minute 32.53 seconds at Okayama International Circuit, 1 minute 17.47 seconds at Central Circuit, 1 minute 23.15 seconds at Sportsland Sugo, and 53.99 seconds at Tsukuba Circuit. In the United States, the CT230R set a new record of 1 minute 43.52 seconds at Buttonwillow Raceway. For the World Time Attack Challenge from 2014 to 2016, HKS developed the HKS GT1000+ Nissan GT-R R35. As the name implies, the GT1000+ produces over 1000 ps at 1200 ps (1183 hp). Driven by Taniguchi, the GT1000+ set a class record at Fuji Speedway of 1 minute 39.85 seconds in 2014 and 1 minute 37.77 seconds in 2015. It also won its class at the WTAC at Sydney Motorsport Park with a time of 1 minute 30.83 seconds. Notably, these lap records claim to be the fastest of any Nissan GT-R R35, and are even on par with the Nissan GT-R GT3 race car. HKS returned to the Tsukuba Circuit in 2018 with the HKS TRB-03, a time attack Toyota 86 producing over 811 ps (800 hp). The TRB-03, again driven by Taniguchi, went on to set a new record and broke the 50-second barrier at Tsukuba with a lap time of 49.44 seconds. The TRB-03 also participated in the 2018 World Time Attack Challenge. Later in 2018, HKS began a project to set the record for a front-wheel-drive tuner car at Tsukuba with the HKS TRB-04 Suzuki Swift. The TRB-04 weighed 930 kg (2050 lb) with a stripped body that heavily used carbon fiber, and was powered by a 4G63 MIVEC inline-four engine making 500 ps (492 hp) with an HKS GTIII turbocharger and sequential transmission. Taniguchi set the FF record at the time, with a lap time of 55.498 seconds in January 2019. Japan Super Sports Championship , entered in the JSS championship In 1984, HKS supported the FJ20ET engined 'HKS World Trade Silvia S12' competing in the JSS (Japan Super Sports) championship with driver Seiichi Sodeyama. Fuji Grand Champion Series HKS participated in the 1986 Grand Champion Series with an original 2000cc DOHC 4 cylinder 5 valve engine called the "186E", based on the BMW M12. The engine was comparable to other F1 V12s of the era such as the Honda RA121E and Ferrari Tipo 038. It was tested in a Lola T91/50 F3000 chassis at Fuji Speedway. The program produced valuable engineering, technology, and brand value growth for HKS. However, the 300E was never used in competition and the Formula One engine program was closed after two years. Japanese Touring Car Championship HKS entered in the 1992 Japanese Touring Car Championship Group A, the top Japanese automobile race at the time. The team won the race at Sugo with the specially developed HKS Nissan Skyline GT-R (R32). This R32 Skyline GT-R gained popularity with its HKS "Oil Slick" livery, growth of the HKS brand during the period, and coverage in Option magazine, as well as the general success of the R32 GT-R within homologated Group A motorsports at the time. From 1994 to 1997, the team entered the HKS Vauxhall Cavalier and HKS Opel Vectra in the JTCC. The team won three races in 1994, finishing 4th overall in 1994 and 1995.
