B Dasher

The B Dasher is a kart from the Mario Kart series. It is a long, skinny, white kart with a red stripe along the front and a massive engine block with four large exhaust pipes. The emblem is located on the hood. It appears on the box art of Mario Kart DS, and it resembles a classic 1960s Formula 1 car. It is the first vehicle in the series to have a racing car design; a feature that has became staple in the subsequent games, in which one or two vehicles have a racing design. Its name is most likely a reference to the controls of the side-scrolling platform games, in which the player presses and holds the B button to dash. The in SNES was also used for acceleration in Super Mario Kart.

The Zucchini is similar in design, but with a very different paint job.

In Mario Kart Wii, a kart called the Sprinter (which is the B Dasher's Dutch name) in American English is called the "B Dasher Mk 2" in British English and Japanese, making it the Mario Kart DS kart's successor. The Circuit Special is the successor of the Sprinter, which is called "Sprinter 2.0" in Dutch, making it the B Dasher's second successor.

Mario Kart DS
The B Dasher first appears in Mario Kart DS as Mario's main kart of choice. Like the Standard Kart, it is balanced in stats and has average speed, good handling, sharp drift, above average acceleration, and high items & weight; it is one of the heaviest karts in the game, and its weight is tied with the Streamliner, Royale, Standard DK, Standard WL, Brute and Zipper. Its speed is tied with the Standard MR, Egg 1, Standard DS and Power Flower. Its acceleration sharing with the Standard MR, Standard LG, Streamliner, Royale, Standard PC, and Light Dancer. Its handling tied with the Standard PC, Light Tripper Standard WR, Brute, Dragonfly, Light Dancer, and Zipper. Its drift is tied with the Standard MR. In a minor note, despite its appearance would suggest, it has a weak-sounding two stroke engine, which is the same as Standard Kart.

To let any character use the kart, the player must obtain all the gold cups in 150cc Mirror Mode. Until then, only Mario has the option to use it. Daisy and Waluigi can use this kart after the player has obtained all gold cups in 150cc Nitro or Retro Grand Prix.

Mario Kart 7
The B Dasher reappears in Mario Kart 7 as an unlockable vehicle and is noticeably more powerful than in Mario Kart DS. It features a speed and handling boost, but its acceleration and off-road stats are hindered during the process. In fact, the B Dasher is tied with the Blue Seven and Bolt Buggy for having the lowest acceleration of all kart bodies. However, it is tied with the Blue Seven, Bruiser, and Zucchini for having the highest speed of all kart bodies and is the fastest kart body to have a positive handling boost and to not have a negative impact on the air speed stat.

It now has a four stroke engine and its sound is actually the same as Mini Beast, Wild Wing, and Flame Flyer from Mario Kart Wii.

Equipping the B Dasher with Standard tires makes it resemble the original Mario Kart DS version.

CPU Mario is more likely to be seen driving on this body, often using the Slick wheels and the Super Glider.

Mario Kart 8 / Mario Kart 8 Deluxe
The B Dasher once again returns in Mario Kart 8 as part of the first downloadable content pack, The Legend of Zelda × Mario Kart 8. It uses the same exact stats as the Mach 8, Sports Coupe, Circuit Special, Gold Standard, and P-Wing. The design remains unchanged, aside from the engine being larger and more visible within the exhausts. Its sound suggests that it is possibly powered by a four-cylinder engine. The B Dasher has a noticeable difference in that the exhaust noise is louder and more audible compared to others. It additionally shares the same engine sound with the P-Wing.

In Mario Kart 8 Deluxe, it is unlocked randomly by collecting coins, and its stats have been altered so that it now only boosts speed, weight, and anti-gravity speed, while hindering every single other stat. The acceleration, handling, and mini-turbo are worsened, while the traction is slightly better than before. The B Dasher now only shares its stats with the Circuit Special and P-Wing. CPU Mario, Daisy, Dry Bones, and Iggy are occasionally seen using this body paired with the Standard tires during races.

Mario Kart Tour
The B Dasher returns in Mario Kart Tour where is is classified as a High-End kart. It uses the Pipe Frame's tires. The B Dasher raises the speed boosts and points granted by Dash Panels. The game also introduces three variants, simply named the Black B Dasher, Kabuki Dasher, and Red B Dasher. All four karts share the High-End classification, although the Kabuki Dasher is exclusive to the Tokyo Tour.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, the B Dasher appears as an Ace-class support Spirit, using its artwork from Mario Kart 7. When a fighter is equipped with the B Dasher spirit, it takes up one support slot increases the power of their neutral special moves (for example, Mario's Fireball). The spirit's battle takes place on Figure-8 Circuit, where the player has to face off against a team of Marios who can deal damage by running into the player.
