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 (タイヤ交換), adding the last part of a Shift Car's name to his current Type (i.e, Type Speed Flare). Some of them also come with a weapon called a Tire Specific Item for Drive to wield.

Shift Cars can also be used by Kamen Rider Mach by inserting them into the Mach Driver Honoh. Unlike the Shift Brace, it doesn't require Mach to change the selected Shift Car into its Lever Mode to be inserted.

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. Episode 22 shows that they can also destroy Roidmude constructs, such as the fake murder victims, so much that they were addressed as "guardian spirits".

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. Other Special Investigation Unit members also aware of their existence but dismissing them as Shinnosuke's toy cars.

They can be summoned by calling out their names, and other times they 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.

In episode 21, Medic captures all of the Tire Exchange Shift Cars (except the Type Formula-esque ones) and brainwashes them into being Chase's assistants as they overpower Drive. All of them sport Medic's emblem and are able to travel around without the need of generating tracks in midair. Mashin Chaser tried to use them in a suicide attack against Drive Type Dead Heat, but Drive managed to assume Type Formula and rescue them and Kiriko from the blaze. As of episode 22, the previously enslaved Shift Cars have been purified by Rinna.

Type Change Cars
Type Change Cars change Drive's body, granting him different capabilities and stats, as well as providing him with better compatibility for certain Tire Exchange modes. Many of them require the user to be in a certain state of mind in order for them to be utilized. They all have the ability to be used as Mr. Belt's "eyes" on the field, allowing him to discreetly observe whatever the Type Change Cars are observing, and communicate with Shinnosuke when he isn't around. He can also communicate through more than one of them at the same time.
 * 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. In the toyline, there is also a golden version of the Shift Speed Car, but it works like a normal Shift Speed Car.
 * 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. In the toyline, there is also a golden version of the Shift Wild Car, but it works like a normal Shift Wild Car.
 * 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. When the Tire Exchange Shift Cars went against Shinnosuke and the others, Shift Technic had to stay with Kiriko in order to allow her to move normally in a Slowdown.
 * Shift Dead Heat (シフトデッドヒート): A Shift Car/Signal Bike hybrid that allows Drive to transform into Type Dead Heat, enabling him to access the Dead Zone state. Shift Dead Heat first appeared only as a sidecar part since Rinna still tried to complete it, but got sidetracked by personal problems. Later, it was completed by Harley Hendrickson. Usage of Shift Dead Heat carries the risk of turning the Drive System into an out of control rampant and attack anyone around him. The only way to stop this is to strike Drive with either a finishing move or an attack strong enough and enough times to deactivate Shift Dead Heat's influence on him so that he can cancel the transformation. Usage of Shift Dead Heat can also enable its user to resist Super Heavy Accelerations, but with a drawback of the user's enhanced capabilities being restricted.
 * Shift Formula (シフトフォーミュラ): Allows Drive to transform into Type Formula, equipping him with the Trailer-Hou, as well as enabling him to move faster than Type Speed and manipulate wind. This Shift Car was created by Krim himself a long time ago where, like Shift Deadheat, usage of it can enable Drive to resist Super Heavy Accelerations. However, Krim was forced to hide its existence as Shift Formula's usage is more dangerous than Shift Deadheat.
 * Shift Tridoron (シフトトライドロン): Allows Drive to transform into Type Tridoron. The DX toy version was accidentally released following its inclusion into a Toei Company video.
 * 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. Shinnosuke must be a gentleman in order to use Type High Speed. Only appears in Type HIGH SPEED! The True Power! Type High Speed is Born!.
 * Shift Speed Prototype (シフトスピードプロトタイプ): A prototype version of Shift Speed (black body, different line patterns, purple headlights, and no spoiler) formerly used by Chase that allows Proto-Drive to transform into the prototype version of Type Speed. This Shift Car is currently not used by the present Drive himself.

Tire Exchange Cars

 * Type Speed-esque: 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 Kourin Signal Moerl.
 * 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. If used in Mashin Chaser's Break Gunner, it turns the Revenger Pikes on his Break Gunner into sharp spikes for either punching or shooting when needed.
 * 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.

Legend Rider Shift Cars

 * Shift TriCyclone (シフトトライサイクロン): Allows Drive to activate a Legend Rider Tire Exchange.
 * Shift Ridoron (シフトライドロン): Allows Drive to activate a Legend Rider Tire Exchange.

Viral Cores
Viral Cores (バイラルコア) are devices similar to the Shift Cars that are used by the Roidmudes to evolve them from their weaker Low-Class forms into their stronger Advanced forms. When Chase was originally Proto-Drive, he could use the regular Viral Cores, presuming they were not too damaged, to read the memories of defeated Roidmudes by inserting them into his Shift Brace.

Chrome versions of the Viral Cores, known as Chaser Viral Cores (チェイサーバイラルコア), are used by Drive's rival, Mashin Chaser, to change into his Tune Chaser forms. Unlike the regular Viral Cores, they have as much sentience as Drive's Shift Cars and Mach's Signal Bikes.

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.
 * 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.
 * 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 evolves the Roidmude into a giant bat.

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 Mashin Chaser into his Tune Chaser Cobra form, equipping him with the whip-like Tail Whipper. When initiating Triple Tune, Chaser inserts this Core last.
 * 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 Mashin Chaser into his Tune Chaser Spider form, equipping him with the pincer-like Fang Spidey. When initiating Triple Tune, Chaser inserts this Core first.
 * 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 Mashin Chaser into his Tune Chaser Bat form, equipping him with the crossbow-like Wing Sniper. When initiating Triple Tune, Chaser inserts this Core second.

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.
