《瑪利歐賽車8 豪華版》（Mario Kart 8 Deluxe）是任天堂於2017年4月28日在Nintendo Switch平台推出的競速遊戲，是《瑪利歐賽車8》的加強移植版，並且被視為Switch平台上最具代表性的作品之一。在原作的基礎上進行全面強化，內容更加豐富，玩法也更為多樣，成為系列中最完整的作品。

依然延續系列傳統，並沒有特定的劇情設定。可選擇操控任天堂旗下眾多經典角色，免不了固定班底包括瑪利歐、路易、碧姬公主、耀西、庫巴、大金剛、奇諾比奧、諾可諾可（烏龜）、黛西公主、奇諾比可、壞利歐、壞路易...等等，使用的車子也是可以選擇，各款車子自都擁有著不同的性能。駕駛卡丁車或機車，在不同風格與主題的賽道上進行競速比賽。賽道設計融合創意與挑戰性，並運用《瑪利歐賽車8》首創的反重力機制，使比賽不再局限於平面，而是能夠沿著牆壁或天花板奔馳，增加視覺震撼與操作樂趣。

在操作方面，保持原作簡單直觀的風格，易於上手但富有深度。使用Joy-Con控制器、Pro手把或體感操作方式來進行遊戲，無論是單人遊玩，還是與親朋好友一同分屏競速，或是連線與全球玩家一較高下，都能享受到不同形式的樂趣。特別是Switch的便攜性，可以隨時隨地進行遊戲，提升該作的吸引力。作為加強版，加入大量新要素與改進。例如，所有DLC內容皆已整合，包含額外賽道、角色和車輛等，使遊戲內容更加豐富。從48條賽道中自由選擇，包括16條經典賽道的重製版本，每條賽道都設計精緻，並充分發揮Switch的硬體性能，呈現出細膩的光影效果與流暢的畫面表現。相較前作只有「氣球大戰」，加強版則共有五款玩法:1.氣球大戰~設法擊破對方汽球或用道具搶走對方汽球 2.咚咔！炸彈兵~只能使用炸彈兵攻擊對手，並奪取金幣 3.收集金幣~在有限時間內取得最多金幣即可獲得勝利 4.搶奪陽光~在競賽中取得「陽光星星」的道具，即可獲勝 5.食人花 VS 間諜~可選擇加入逮捕隊的食人花隊或間諜，在時間內抓到所有成員或間諜隊閃避到時間結束就勝利。

新增新角色有「庫巴Jr.」、「黃金瑪利歐」、「碎碎龜」以及「King Boo」等，使角色總數達到42名，是歷代作品中最多的一次。此外，還能選擇因克少年與因克女孩，來自《斯普拉遁》（Splatoon）的特別角色，擴展角色陣容，增添新鮮感與樂趣。道具系統也迎來變革。在本作中，可以同時攜帶兩個道具，使比賽策略性提升。例如，在關鍵時刻保留一個防禦型道具（如香蕉皮）以防止後方攻擊，同時使用攻擊型道具（如紅龜殼）攻擊前方對手，讓競速過程更具變數與刺激感。此外，新加入的道具如「鬼魂」，可以暫時隱形並偷取其他玩家的道具，而「羽毛」則能跳過障礙或躲避攻擊，這些設計進一步強化競技層面。

有針對對戰模式進行重大改進，補足原作《瑪利歐賽車8》中對戰模式較為薄弱的部分。豪華版新增專屬對戰地圖，例如「戰場大道」、「幽靈屋」和「甜點土地」等，每張地圖都有獨特的地形與機關，使對戰更加多元化。對戰模式包含氣球對戰、炸彈對戰和搶奪陽光標誌等，不僅要競速，還要與對手互相角逐，利用道具和場地特性進行攻防，增添整體的多變性與娛樂性。主機連線支援8位玩家，線上連上最多12人。有網路直播功能「瑪利歐賽車TV」，可以將精采賽況影片跟全世界玩家分享。

畫面表現方面，本作全面支援1080p高清畫質（掌機模式為720p），並且在畫面精細度和特效上均有所提升。角色與賽車的細節更加豐富，水面反射、煙霧與粒子效果也更加真實，帶來視覺上的享受。賽道設計充滿層次感，特別是在反重力區域，賽道的立體感與空間感展現得淋漓盡致，在賽道上疾馳時充滿速度感與沉浸感。音樂方面，延續8代的高品質表現，所有賽道音樂皆由現場管弦樂團錄製，為玩家帶來震撼的聽覺體驗。每條賽道的背景音樂都與其主題完美契合，例如雪山賽道的激昂旋律、甜點賽道的輕快節奏，以及庫巴城堡的壓迫感音樂，均為比賽氛圍增添不少分數。

發售後，迅速成為Nintendo Switch平台的暢銷作品之一，並獲得極高的市場評價。媒體普遍稱讚其豐富的遊戲內容、多樣的角色與賽道設計，以及流暢的操作體驗。IGN給予本作9.3/10的高分，認為其「無論在單人還是多人模式下都能帶來極致的競速體驗」。GameSpot則給出9/10，強調其「是所有Switch玩家必備的遊戲之一」。玩家社群對於本作也給予高度肯定，尤其讚揚其適合家庭娛樂和朋友聚會，同時又具備深度競技性，使遊戲的壽命與耐玩度極高。截至目前已累積銷量超過6400萬份，成為Switch平台銷量最高的遊戲，並在全球競速遊戲中佔有舉足輕重的地位。

這不僅是對競速類型的全面昇華，更是對《瑪利歐賽車》系列的致敬與突破，以其精緻的畫面、創新的反重力機制、多元的角色選擇和趣味十足的對戰模式，為帶來前所未有的競速體驗。

Mario Kart 8 Deluxe is a racing game developed by Nintendo, released on April 28, 2017, for the Nintendo Switch. It is an enhanced port of Mario Kart 8 and is regarded as one of the most iconic titles on the Switch platform. Building upon the original, the Deluxe edition introduces numerous improvements, richer content, and more diverse gameplay, making it the most complete entry in the series.

The game follows the traditional style of the series and does not feature a specific storyline. Players can choose from a wide range of classic Nintendo characters, including Mario, Luigi, Princess Peach, Yoshi, Bowser, Donkey Kong, Toad, Koopa Troopa, Princess Daisy, Toadette, Wario, and Waluigi, among others. A variety of vehicles are also available, each with unique performance attributes.

Players race karts or bikes across tracks with different themes and designs. The track designs blend creativity with challenges and incorporate Mario Kart 8's signature anti-gravity mechanic. This allows racers to drive along walls and ceilings, adding visual excitement and gameplay variety beyond traditional flat tracks.

In terms of controls, the game retains the original’s simple and intuitive style, making it easy to pick up but offering depth for seasoned players. Players can use Joy-Con controllers, the Pro Controller, or motion controls. Whether playing solo, in split-screen with friends and family, or online against players worldwide, the game provides enjoyment in various formats. The portability of the Switch adds further appeal, allowing gameplay anytime, anywhere.

As an enhanced version, Mario Kart 8 Deluxe introduces numerous new features and improvements. All downloadable content (DLC) from the original is integrated, including additional tracks, characters, and vehicles, enriching the overall experience. Players can choose from 48 tracks, including 16 remastered classic tracks. Each track is intricately designed, fully utilizing the Switch’s hardware capabilities to deliver refined lighting effects and smooth visuals.

Compared to the original, which only featured the "Balloon Battle" mode, the Deluxe version introduces five battle modes:

Balloon Battle – Pop opponents’ balloons or steal them using items.

Bob-omb Blast – Attack opponents with Bob-ombs and collect coins.

Coin Runners – Collect as many coins as possible within a time limit.

Shine Thief – Obtain and hold the "Shine Sprite" to win.

Renegade Roundup – Players join either the Piranha Plant team (enforcers) or the Renegades (spies). Enforcers try to capture all Renegades, while Renegades attempt to avoid capture until time runs out.

New characters, such as Bowser Jr., Dry Bones, Gold Mario, and King Boo, bring the total roster to 42—the largest in the series' history. The game also includes Inkling Boy and Inkling Girl from Splatoon, expanding the character lineup and introducing fresh elements.

The item system has also been revamped. Players can now carry two items simultaneously, enhancing strategic gameplay. For instance, players can hold a defensive item (like a banana) to block incoming attacks while using offensive items (like a red shell) to attack opponents ahead. New items, such as the Boo, which turns players invisible and steals items from others, and the Feather, allowing players to jump over obstacles or avoid attacks, further deepen the competitive aspect.

The battle mode has received significant improvements to address weaknesses in the original Mario Kart 8. Exclusive battle maps like Battle Course 1, Luigi’s Mansion, and Sweet Sweet Kingdom feature unique terrains and obstacles, diversifying the battle experience. Battle modes include balloon battles, coin collecting, and Shine Thief, adding layers of offense and defense that enhance the game’s overall variability and entertainment. The game supports up to eight players in local multiplayer and up to 12 players online. Additionally, the "Mario Kart TV" feature allows players to share highlight reels with others worldwide.

Visually, the game fully supports 1080p HD resolution (720p in handheld mode). The detail and effects have been improved, with enhanced character models, water reflections, smoke, and particle effects, creating a visually immersive experience. Tracks are designed with layers and depth, especially in anti-gravity zones, where the three-dimensional layouts provide a thrilling sense of speed and immersion.

In terms of music, the game continues Mario Kart 8's high-quality presentation. All track music is performed by a live orchestra, delivering an exhilarating auditory experience. Each track’s background music complements its theme perfectly, such as the intense melodies for snowy tracks, the cheerful rhythms for dessert-themed tracks, and the powerful tunes for Bowser’s Castle.

Following its release, Mario Kart 8 Deluxe quickly became one of the best-selling games on the Nintendo Switch and received widespread acclaim. Critics praised the game’s rich content, diverse characters and tracks, and fluid gameplay. IGN awarded it a 9.3/10, describing it as "the ultimate racing experience whether in single or multiplayer modes." GameSpot gave it a 9/10, calling it "a must-have for all Switch owners."

The player community also responded enthusiastically, highlighting the game’s suitability for family entertainment and social gatherings, while also appreciating its competitive depth. As of now, the game has sold over 64 million copies, making it the highest-selling title on the Switch and solidifying its position as one of the most influential racing games globally.

Mario Kart 8 Deluxe is not only a refinement of the racing genre but also a tribute and evolution of the Mario Kart series. With its polished graphics, innovative anti-gravity mechanics, diverse character selection, and engaging battle modes, it delivers an unparalleled racing experience.
