Mazda RX-7

Mazda RX-7 is a sports car produced by the Japanese automaker Mazda from 1978 to 2002. The original 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 (both were sold in Japan as the Savanna) and later replaced all other Mazda rotary-engine cars except the Cosmo.

The original RX-7 was a sports car. The compact and lightweight Wankel engine (rotary engine) is situated slightly behind the front axle, a configuration marketed by Mazda as "front mid-engine". It was offered as a two-seat coupé, with optional "occasional" rear seats in Japan, Australia, the United States, and other parts of the world. These rear seats were initially marketed as a dealer-installed option for the North American markets.

FC3S

 * Ryosuke Takahashi drives a white Mazda RX-7 FC3S. He uses this RX-7 as his primary mode of racing, being called "Akagi's White Comet" in the past. Downgrading his car, he uses it in an attempt to defeat Takumi Fujiwara but loses when the latter overtook him on the outside just as the FC's tires began to wear out. The victory hands Ryosuke Takahashi his first loss and allowing Takumi to be the new downhill legend. Ryosuke temporarily retired, but later made a comeback and used this car once more in a showdown against Kyoichi Sudo in an attempt to defend the Redsuns' home course at Akagi. He would later use the car in a race against Takumi Fujiwara when the latter was deciding to join the newly formed Project D. Ryosuke would later modify his FC in a race against Rin Hojo, with the latter wanting to take revenge on the former for Kaori.

FD3S

 * Keisuke Takahashi is the owner of a competition yellow Mazda RX-7 FD3S. He uses this RX-7 as his primary mode of racing. Throughout the rest of the series, his RX-7 has physically changed. It first started out with a set of white rims and Mazdaspeed bumpers and wings. It would later have MS-02 rims and a new front bumper and spoiler when Keisuke joined Project D, though the Redsuns sticker would be removed during that time. When Keisuke's FD was damaged by the Tsuchisaka Lan Evo Team during a trial run, his FD would undergo a major modification; gaining a RE Amemiya body kit, a new spoiler, and a pair of bronze SSR rims, in which he would use the newly modified FD to take on much stronger opponents such as Kozo Hoshino, Kobayakawa, and Go Hojo. During the disbandment of Project D, Keisuke would later use his FD in professional racing, souping it up with decals while retaining the same body kit.
 * Kyoko Iwase drives a black 1993 Efini RX-7 Type-R that she uses to race against Keisuke. When Keisuke's FD gets damaged by the Tsuchisaka Lan Evo Team, he borrows her RX-7 so he can take on Aikawa.
 * The imposter Keisuke of the Fake Project D has his own Mazda RX-7 similar to the one owned by the real-life counterpart.
 * In the music video of Raimei -out of kontrol- by the band M.o.v.e, band members motsu and t-kimura are turned into animated versions of themselves and transported to a red Mazda RX-7 similar to the one owned by Kyoko. Motsu acts as the driver while t-kimura is the passenger, and race against Takumi Fujiwara in the AE86 during the music video.
