Regalia

Regalia, also identified by its license plate RHS-113, is the party's car and mode of transportation on the field in Final Fantasy XV. It is a black convertible driven by Ignis.

According to director Hajime Tabata, players should consider the car a member of the party, as one would consider an airship of previous Final Fantasy games also a piece of the party. The car symbolizes the open world and the freedom in the game, as well King Regis's presence, as the car was originally his. The car is a metaphor the journey will be preserved by his father and also represents the relationship between Noctis and him.

Appearance
The car is a black four-seat convertible with dark leather interior. The hubcaps have chocobo talon motifs as homage to the birds usually being a common field transport method in the series. It has a single license plate at the back and it lights up in the dark.. The plate reads "Insomnia" above the "RHS-113," referring to the capital of Lucis and Regis being its 113th ruler. The bottom of the plate says "The Royal Capital," further denoting this.

The real world concept car resembles the Regalia in appearance. It also resembles the real world sports car, particularly in the front bumper and grille. It is unknown if these, or any other car model, was used as inspiration when designing the car for the game, although Tabata has said this about its design: "I can't really tell exactly you which company we looked at, but certainly the design of the car in the game was inspired by German car manufacturers and a couple of British cars, as well."

When the game was known as Versus XIII, the car resembled the and had a panoramic roof that stretched to its trunk.

Story
Prince Noctis Lucis Caelum and his friends—his royal advisor Ignis, his bodyguard Gladiolus and his childhood friend Prompto—head out to meet Noctis's fiancée Lunafreya Nox Fleuret in Tenebrae in Regalia, King Regis's car. On their Prompto wrecks the vehicle and they need to raise the funds to have Cindy repair it.

Gameplay
The car can be set to autopilot driven by Ignis, or be driven manually by the player,, and during car rides one can listen to the characters' conversations. The car can be customized by the player, possibly with parts dropped by monsters.

During the "Walkthrough" trailer released during Paris Games Week at the end of October 2014 the player flashes the car's headlights and an oncoming NPC car reacts to it by wiggling.

The developers looked at games like Need for Speed in making the driving mechanics enjoyable and fun. The driving is meant to replicate the feel of controlling a car without going into the nitty-gritty. Players will travel mostly by car, although it is also possible to go by foot, although this is generally not advisable as some places can be far off; walking is primarily reserved for reaching places that can't be entered by car. The Tokyo Game Show 2014 trailer shows the party driving on a stone arch near an astral shard, but generally the car cannot be driven off the road. If the player becomes separated from the car, they can summon it.

Enemies can attack while the party is riding in the car and they must get out to fight.

Trivia

 * During the livestream talk show on 2nd October 2014, Director Hajime Tabata brought up the Internet memes featuring the Final Fantasy XV party in the car, looking off to the side, that had been Photoshopped in a number of ways. Square Enix released art assets of this scene for fans to mess around with to encourage more memes to bring publicity for the game.
 * The car was planned to be included in the Final Fantasy XV Episode Duscae demo, but was removed. Hajime Tabata explained his reason for the decision to be that he didn't want the demo to deviate too far from what the fans expect from a Final Fantasy game by making it driving-focused. There will be a sequence in the full game where the party loses their car and the demo was created around that sequence.
