Shift Cars

"Go Forth, comrades! Protect the humans!"

- Drive Driver ordering the Shift Cars to rescue humanity in Global Freeze

The Shift Cars (シフトカー), powered by Core Driviars, are miniature cars created for the purpose of helping humanity. They are used by Kamen Rider Drive in conjunction with his belt, the Drive Driver, and bracelet, the Shift Brace, which work together via infrared, when he changes them from their Machine Modes (マシンモード) to their Lever Modes (レバーモード) by rotating them.

Some Shift Cars enhance Drive's current Type form with a Tire Exchange, adding the last part of a Shift Car's name to his current Type (i.e, Type Speed Flare). Some Tires come with a weapon for Drive to wield.

They are able to attack Roidmudes by traveling on special tracks that they spawn, and are strong enough to incapacitate unevolved Roidmudes. As long as someone has a Shift Car on their person, they are able to ignore the time distortions a Roidmude emits when active, unless multiple time distortion effects occur. In this case, one must have multiple Shift Cars on their person.

Their most unique attribute though is their capacity for sentience and sapience. Though they cannot speak, Shift Cars can feel emotions such as mischievousness, frustration, happiness and even more complicated feelings such as regret and loss, and can show these emotions through their beeping or through car signs they spawn alongside their tracks. Only Shinnosuke, Mr. Belt and Kiriko are shown to be able to understand them so far.

They can be summoned by Shinnosuke and Kiriko by calling their names, or can simply come of their own volition. Throughout the series they are off investigating their own cases, but return to Drive when they are done gathering data to assist him in battling Roidmudes.

Only Type Change Cars can be controlled by Mr. Belt to communicate with Shinnosuke when he isn't around. Mr. Belt can also communicate via more than one of them at the same time.

Shift Cars can also be used by Kamen Rider Mach by inserting them into the Mach Driver Honoh.

Devices similar to Shift Cars, known as Viral Cores (バイラルコア), are used to evolve lesser Roidmudes into more powerful forms. Chrome versions of the Viral Cores are also used by Drive's rival, Mashin Chaser. Viral Cores can also be used by Kamen Rider Proto-Drive to read the memories of defeated Roidmudes.

Type Change Cars
Type Change Cars change Drive's body, granting him different capabilities and stats and providing better compatibility with certain Tire Exchange modes. Many of them need to have the user be in a certain state of mind in order to utilize. All of them have the ability to be used as Mr. Belt's "eyes" on the field, allowing him to discreetly observe whatever the Type Cars are observing.
 * Shift Speed (シフトスピード): Allows Drive to transform into Type Speed, granting him acceleration capabilities that enable him to move and attack at high velocities. Because Type Speed is Drive's main form, it doesn't need any special requirements or emotional frames of mind for Shinnosuke to access.
 * Shift Wild (シフトワイルド): Allows Drive to transform into Type Wild, granting him enhanced strength and defensive capabilities. It can also transform Tridoron into its dune buggy-based Type Wild mode. Shinnosuke must be pumped up and motivated to fight in order to use Type Wild.
 * Shift Technic (シフトテクニック): Allows Drive to transform into Type Technic, enabling him to easily analyze and control machines. Drive also gains almost pin-perfect precision, allowing him to easily react and analyze changes in the battlefield with lightning speed, as well as multitask with the help of the eyes in the back of his head. It can also transform Tridoron into its garbage truck-based Type Technic mode. Shinnosuke must have a cool, calm, and clear mind in order to use Type Technic.
 * Shift Deadheat (シフトデッドヒート): A Shift Car/Signal Bike hybrid that allows Drive to transform into Type Deadheat. It can also be used by Kamen Rider Mach to transform himself into Deadheat Mach.
 * Shift Formula (シフトフォーミュラ): Allows Drive to transform into Type Formula, equipping him with the Trailer Cannon.
 * Shift Fruits (シフトフルーツ): Allows Drive to transform into Type Fruits, equipping him with the Musou Saber and Daidaimaru, as well as enabling him to use Kamen Rider Gaim's abilities. Only appears in Kamen Rider × Kamen Rider Drive & Gaim: Movie War Full Throttle.
 * Shift High Speed (シフトハイスピード): Allows Drive to transform into Type High Speed. Only appears in Secret Mission 3.
 * Shift Speed (prototype) (Based on a concept sports car): Allows Kamen Rider Proto-Drive to transform. It is a prototype version of Shift Speed, with a black body, different line patterns, purple headlights, and no spoiler. Currently not used by the present Drive himself.

Tire Exchange Cars

 * Type Speed-matchable: These Shift Cars are based on regular cars with four wheels.
 * Shift Max Flare (シフトマックスフレア): Allows Drive to gain the Max Flare Tire, granting him fire-enhanced abilities. By itself, it can attack by igniting the tracks it spawn with intense fire, which can also boost the attacks of the other Shift Cars. If used in Mashin Chaser's Break Gunner, it allows him to shoot fireballs. The same effect applies to Kamen Rider Mach's Zenrin Shooter if he uses it in his Mach Driver Honoh to activate the Advent Signal Moeeru.
 * Shift Funky Spike (シフトファンキースパイク): Allows Drive to gain the Funky Spike Tire, enabling him to either shoot spikes or impale enemies on the tire. By itself, it can attack by slamming itself into enemies while extending its spikes.
 * Shift Midnight Shadow (シフトミッドナイトシャドー): Allows Drive to gain the Midnight Shadow Tire, granting him enhanced stealth capabilities that enable him to duplicate himself and the ability to throw energy shuriken. By itself, it can attack by shooting energy shuriken and creating copies of itself.
 * Shift Justice Hunter (シフトジャスティスハンター): Allows Drive to gain the Justice Hunter Tire, equipping him with the Justice Cage to either protect himself or trap enemies. By itself, it can generate low barriers resembling Justice Cages to trip over its prey. As befitting a policeman, it has a very orderly personality and comes into conflict with the reckless Massive Monster, but in the end cares for it very much.
 * Shift Dream Vegas (シフトドリームベガス): Allows Drive to gain the Dream Vegas Tire, equipping him with the Drum Shields to either protect himself or merge with the main tire for the finisher. By itself, it can attack by shooting playing cards. It is best friends and partners with Dimension Cab, and performed badly during its first use by Drive due to its hatred of Roidmude 010, but bonding with Shinnosuke allowed Vegas to regain its normal level of performance, which helped him in destroying 010 for good.
 * Shift Dimension Cab (シフトディメンションキャブ): Allows Drive to gain the Dimension Cab Tire, enabling him to generate a portal from it that separates a portion of his body to use to either teleport himself or attach himself to objects, possibly even going through them. By itself, it can attack by utilizing its portal-generation powers to maximum effect. Partners and best friends with Dream Vegas, it was incapacitated during Global Freeze by Roidmude 010, but was repaired six months later with compound S-01 and it returned in episode 4 to help Drive escape from Mashin Chaser.

Regular Cores

 * Cobra Viral Core (コブラバイラルコア): A Viral Core that can give a new body for the Cobra-type Roidmudes‘ core, though when three are used instead, it allows the Roidmude to evolve into a giant cobra. Could also be used by Proto-Drive to read the memories of the Roidmude it came from, presuming the Viral Core was not too damaged.
 * Spider Viral Core (スパイダーバイラルコア): A Viral Core that can give a new body for the Spider-type Roidmudes‘ core, though when three are used instead, it evolves the Roidmude into a giant spider. Could also be used by Proto-Drive to read the memories of the Roidmude it came from, presuming the Viral Core was not too damaged.
 * Bat Viral Core (バットバイラルコア): A Viral Core that can give a new body for the Bat-type Roidmudes‘ core, though when three are used instead, it presumably evolves the Roidmude into a giant bat. Could also be used by Proto-Drive to read the memories of the Roidmude it came from, presuming the Viral Core was not too damaged.

Chaser Cores

 * Chaser Cobra Viral Core (チェイサーコブラバイラルコア): An enhanced Viral Core that summons the E-Circular and turns Chaser into his Busou Chaser Cobra form, armed with the Tail Whipper (テールウィッパー).
 * Chaser Spider Viral Core (チェイサースパイダーバイラルコア): An enhanced Viral Core that summons the E-Circular and turns Chaser into his Busou Chaser Spider form, armed with the Fang Spidey (ファングスパイディ).
 * Chaser Bat Viral Core (チェイサーバットバイラルコア): An enhanced Viral Core that summons the E-Circular and turns Chaser into his Busou Chaser Bat form, armed with the Wing Sniper (ウィングスナイパー).

Other Cores

 * Lupin Blade Viral Core (ルパンブレードバイラルコア): A Viral Core used by Kamen Rider Lupin, allowing him to use the blade mode on his Lupin Gunner.
