These include a hovercraft (Assoluto Pronzione), a tripod supercar (Himmel 490B) and an oversized SUV that can be very loud (Danver Bass Cruiser).

Online multiplayer is possible with up to 14 players racing against each other and downloadable content was available via Microsoft's Xbox Live service.

Hiroshi Okubo served as the game's sound director, while the soundtrack also has contributions from in-house composers Keiki Kobayashi, Rio Hamamoto, Tetsukazu Nakanishi, Yuu Miyake, Koji Nakagawa, Junichi Nakatsuru, and Akitaka Tohyama.

Several contractors who formerly worked in-house include the original Ridge Racer sound team consisting of Shinji Hosoe, Ayako Saso, Nobuyoshi Sano, and Takayuki Aihara, as well as Asuka Sakai and Kohta Takahashi, both of whom composed for R4: Ridge Racer Type 4.

[8] Music from the previous two games in the series, Ridge Racer (PSP) and R: Racing Evolution, was made available for download through the Xbox Live Marketplace in 2006.

[9] Due to high demand from fans, a soundtrack CD titled Ridge Racer 6 Direct Audio was released under SuperSweep Records on 14 January 2009.

An extra disc was also included with purchases from SuperSweep's web store SweepRecord, featuring a DJ mix of its music by Yousuke Yasui.

[25] GameSpy praised the game's "killer graphics" and "great presentation", though it took issue with its stuttering framerate in split-screen multiplayer.
