The Mazda GTP is an IMSA GTP car that was built by Pierre Honegger in 1981.
 Based on a Mazda RX-7, the car initially competed in the GTX category as the Mazda RX-7 GTP, before it was rebuilt for the IMSA GTP category in 1983.
 Throughout its career, the car used a Mazda 13B Wankel rotary engine, similar to that used in the production RX-7s.
 Although the rotary-engined sports prototypes generally had a reputation of being very reliable, the Mazda GTP frequently failed to finish races, and was never able to better the eighth place achieved at the 1983 24 Hours of Daytona.
 In 1986, one car was purchased by Erie Scientific Racing, and rebuilt to become the Badger BB.
 This car was no more successful or reliable than its predecessor, and was last used in 1989, by which point it was owned by Jack Engelhardt.
 The other car, meanwhile, was rebuilt by Honegger into the Denali Speedcar, which was used with moderate success in 1986 and 1987.
The Mazda F platform is an automobile platform for rear wheel drive sports cars.
 It was the basis for three generations of the Mazda RX-7.
Mills Extreme Vehicles (MEV) is a kit car design and manufacturing company based in Mansfield, UK.
 It was founded in 2003 by Stuart Mills.
 As of January, 2016 they manufacture the Exocet and the Replicar, the former an exoskeletal design, the latter a full body design inspired by the Aston Martin DBR1 of the late 1950s.
 Both cars use the Mazda MX5 Mk1 sports car as their foundation.
 They also produce an enhanced version of the Exocet, the MX150R which currently runs in a UK race series regulated by the 750 Motor Club and the MSA.
The Mazda RX-9 is a sports car produced by the Japanese automaker Mazda scheduled for release in 2020.
 "Holiday Auto", a Japanese magazine, reported it will be previewed at the 2017 Tokyo Auto Show, and the final production model will be featured at the same event in 2019.
 The car will be released in January 2020, to coincide with Mazda's 100th anniversary, and will be initially priced at eight million yen (US$(8000000/ 105.944781 )round0 in 2015).
 It is believed it will showcase the return of the Wankel rotary engine, but CEO Masamichi Kogai said Mazda will not launch another rotary engine.
 In the middle of the September 2017, Mazda has filed a patent application for an engine that uses two conventional turbochargers and an electric supercharger.
 The engine looks compact, can replace the rotary engine and possibly be included in RX-9 production.
The Mazda B-Series is a pickup truck that was first manufactured in 1961 by Mazda.
 Since the launch of the B-Series, Mazda has used the engine displacement to determine each model's name; the B1500 had a 1.5 L engine and the B2600 had a 2.6 L engine.
 In Japan, the name Mazda Proceed was used for the compact pickup.
 Other names used for this line include Mazda Bravo (Australia), Mazda Bounty (New Zealand), Mazda Magnum/Thunder/Fighter (Thailand), and Mazda Drifter (South Africa).
The Mazda RX-8 Hydrogen RE is a 2003 bi-fuel version of the RX-8 sports car, in which the twin-rotor wankel rotary engine is configured to run on either hydrogen or gasoline.
 This is the fifth Mazda vehicle to be fitted with a hydrogen wankel rotary engine.
 The hydrogen tank, with a capacity of 110 liters at 350 bar stores up to 2.4 kilograms of hydrogen and is fitted in addition to the 61 liter gasoline tank.
 In 2005, Mazda obtained street approval for this vehicle.
 The following year, the first vehicles were leased to customers (Idemitsu and Iwatani).
 In November 2007, Mazda announced the delivery of 30 RX-8 HRE to the Norwegian hydrogen project Hynor.
The Mazda RX-7 is a sports car that was assembled and produced by the Japanese automaker Mazda from 1978 to 2002.
 The first RX-7 featured a 1146 cc twin-rotor Wankel rotary engine and a front-midship, rear-wheel drive layout.
 The RX-7 replaced the RX-3, with both models sold in Japan as the Mazda Savanna.

Kathy Rude (born 1957) is an American sports car driver who was one of the first female drivers to attract international attention.
 Growing up in Victoria, Canada, she began competing as a teenager in karting events.
 By her early 20s, after competing in Formula Ford and Formula Atlantic, she attracted the attention of several top-tier car owners, and tested an IndyCar owned by Dick Simon.
 She was a member of the original North American Toyota factory-sponsored IMSA GT Championship sports car team in 1981.
 In February 1982, co-driving a factory-sponsored Mazda RX-7 with Allan Moffat and Lee Mueller, she earned a GTU class victory at the 24 Hours of Daytona—the first woman ever to win a major professional sports car event.
 She signed a deal to make her debut at the Indianapolis 500 in 1984, but during an IMSA sports car event at Brainerd, Minnesota in July 1983, she suffered horrific injuries in a crash which ended her racing career.
 Noted sports car champion Brian Redman once referred to her as the only female driver he'd encountered who posed a genuine threat to win major professional automobile races.
 She is now a corporate safe driving instructor and speaker.
