This and other new content is accessible via the Pit Stop, an in-game shop that allows players to purchase unlockables using Wumpa Coins earned through gameplay or obtained via microtransactions.

[3][4] A total of eight Grand Prix events were held between July 2019 and March 2020, though one final wave of new content was released after their conclusion.

[7] Several additional characters have been added as part of free post-launch game updates, and can be unlocked through progression in Grand Prix events or via the Pit Stop.

[8] New racers include Tawna, N. Brio, Koala Kong and the Lab Assistant from the original Crash Bandicoot;[6] Komodo Moe from Cortex Strikes Back; Baby T. and the Iron Checkpoint Crate from Warped; Ami, Isabella, Megumi and Liz, who appeared as non-playable characters in Team Racing;[9] two versions of Rilla Roo from Bash;[8] Megamix from The Huge Adventure;[10] Chick and Stew, who appeared as non-playable characters in Tag Team Racing;[8] baby versions of Crash, Coco, Cortex and N.

[13][14][15] In an interview, Vicarious Visions producer Kara Massie did not rule out the possibility of a remaster of Crash Team Racing for the PlayStation 4.

Much like N. Sane Trilogy, the game was recreated from the ground up with new assets, online play, and added new content including all characters, tracks, battle arenas, kart customizations and battle modes from Crash Nitro Kart, which was developed by Vicarious Visions, who also developed the N. Sane Trilogy.

[21] Players who pre-ordered the game received a set of "Electron" character skins for Crash, Coco and Cortex.

A premium "Nitros Oxide Edition" of Nitro-Fueled was announced alongside the game in December 2018, while its contents were detailed in April 2019.

[27] In August 2019, as part of a co-promotion with Mondelez International, codes for candy-themed kart customization items were included with specially-marked packages of Sour Patch Kids and Trident Vibes.

[28] An additional vehicle, the "Firehawk", was released as paid downloadable content in October 2019 to support the Call of Duty Endowment.

[31][32][33] Critics praised the graphics, tight controls, massive amount of content and faithfulness to the original racing games, though it was criticized for its high difficulty curve, lack of difficulty options, very long loading times, and issues with online play on the PlayStation 4 version of the game.
