How Apple CarPlay and CarPlay Ultra Differ

Both Apple CarPlay and CarPlay Ultra are systems designed to use iPhone features safely inside the vehicle. The former brings an iPhone-oriented interface to the in-vehicle display. The latter extends the display range to the entire vehicle, handling everything from instrument clusters to climate controls. The difference between the two goes beyond the number of screens. They differ in the depth of involvement in vehicle control and in the nature of collaboration with automakers.

According to reporting by Engadget’s staff@engadget.com (Filipe Espósito), the two approaches share a common foundation but have different end goals. The standard version focuses on improving convenience and safety. The Ultra version aims to reconstruct the entire in-vehicle experience around Apple’s design philosophy. At present, there is a significant gap in the breadth of supported models. This gap will be a factor determining future adoption.

Instead of being limited to the infotainment screen, it can control more aspects of your car.

As the above quote indicates, the key point of Ultra is breaking free from the constraints of a single screen. Below, we outline in order how each system works and its limitations, its integration scope, and its adoption status.

How Standard CarPlay Works and Its Limitations

Standard CarPlay was introduced in 2014 alongside iOS 7.1. It is used by connecting an iPhone to the vehicle via a wired or wireless connection. The in-vehicle display shows a simplified interface designed for easy use while driving. It is fundamentally designed to reduce driver distraction. It is structured on the premise of using map operations and voice guidance.

Supported apps are limited. Use is narrowed to navigation, audio streaming, and short messaging. Apple Music playback and route guidance via Maps can be operated by voice. In many cases, basic operations can be completed via voice commands with Siri. This has the effect of reducing the need to pick up the mobile device itself while driving.

However, integration with vehicle-side functions is shallow. Functions such as climate control and drive mode changes may remain within the vehicle’s native interface. There are situations where you need to leave the CarPlay screen to operate them. If the number of steps increases, the burden while driving may grow. From a safety perspective, this fragmentation remains an issue.

Although connection methods have diversified, the basic structure remains unchanged. The display target is primarily the central in-vehicle display. The instrument cluster and additional displays remain under the vehicle’s management. Apps do not handle vehicle information directly. The iPhone and the vehicle are loosely coupled.

There have also been reports of some automakers reconsidering support for CarPlay. Even so, it has a track record of use in more than 800 models. The standard version has become the de facto standard for mobile device integration in vehicles. For developers, it is one of the environments they must support. For users, it offers the advantage of maintaining a consistent user experience even when switching vehicles.

Advances on the iPhone side also extend to the in-vehicle experience. Improvements in voice assistance and map accuracy directly benefit users inside the car. As covered in iPhone Duo Supports Apple Pencil Only via USB-C, changes in connection specifications on the device side affect relationships with peripheral devices. The vehicle side is also required to keep up with connection standards and wireless methods. The time gap between device updates and long-term vehicle use becomes a challenge. Coordination between automakers and the supply chain becomes important.

CarPlay Ultra Integration Scope and Features

CarPlay Ultra is an extended version whose concept was unveiled in 2022. Instead of a single screen, it targets all displays inside the vehicle. It also covers instrument displays such as the speedometer and fuel gauge. It integrates climate and audio system controls into the same interface. It is designed to reduce the need to switch screens to operate the vehicle.

Customization of appearance is also a feature. Users can change the design and configuration of the instruments. It is touted as offering freedom akin to racing game software. Display styles can be tailored to the driver’s preferences. The aim is to bring the consistent feel common to Apple products into the vehicle.

Technically, deep integration with vehicle signals is a prerequisite. Vehicle states such as speed and remaining fuel must be reflected without delay. Results of climate settings and volume operations must also be immediately reflected in the display and operation. Coordination with the vehicle’s control systems is indispensable. Balancing safety and responsiveness is at the core of the design.

The development and validation burden is greater than for the standard version. Display size and resolution differ by model. Control layouts also differ between right-hand drive and left-hand drive. It is also necessary to ensure instrument displays comply with regulations in each country. It is a structure that cannot be realized without joint development with automakers.

The benefit for users lies in operational consistency. Navigation, audio streaming, communication, climate control, and instrument checks can all be handled within the same system. This may reduce the learning curve and help prevent erroneous operations. Combined with voice operation, it can reduce eye movement. It may contribute to reducing fatigue on long drives.

On the other hand, the situation for automakers is complex. It involves entrusting the core of the operating system to an outside company. It competes with their own unique user experiences and feature differentiation. Issues such as handling of collected data and clarification of responsibility boundaries also need to be addressed. Adoption decisions are not determined by technical superiority alone.

Adoption Status and Automakers’ Response

The standard version is supported in more than 800 models and has become widely established. For users with mobile devices, it has become a prerequisite when choosing a vehicle. In the used car market, whether it is supported can be a factor in valuation. For automakers, it offers a sales promotion advantage. Even with moves to discontinue support, the installed base remains large.

The current state of the Ultra version is contrasting. At present, availability is limited to a portion of luxury vehicles. Availability in Aston Martin vehicles in the United States and Canada is leading the way. A support plan by Porsche was also reported but has not materialized. The rollout remains at a limited stage.

The background is seen as a difference in development systems. The standard version could be introduced by supporting a single display. The Ultra version requires crafting the entire vehicle, including the instrument cluster. Compatibility testing and quality assurance processes increase for each model. Expanding to mass-production models takes time.

Automakers’ strategies also diverge. Some companies are strengthening their own in-vehicle operating systems. There are also moves to develop voice assistance and mapping functions in-house. There are also compromise approaches that retain mobile device integration while maintaining control. Adoption of Ultra has started as a proof of concept in the high-end segment.

There is also a gap in consumer awareness. While the CarPlay name is known, the details of Ultra have not penetrated. Dealership explanation systems are also seen as still being developed. The small number of supported models hinders broader awareness. Lack of opportunities to experience it delays the establishment of its reputation.

The future focus is on the pace of expansion of supported models. The question is whether the track record in luxury vehicles will spread to the mid-price range. How automakers will coexist their proprietary systems with external systems is also important. Clarification of connection stability and update systems is also required. Maintenance plans that accommodate long-term vehicle use will be necessary.

Editorial Opinion

On short-term impact: We do not expect a rapid increase in Ultra-compatible models in the next three to six months, as adaptation development and validation take time. We assess that the standard version will remain the practical mainstream. Automakers may prioritize improving their proprietary systems. Users need to check for Ultra compatibility at the time of purchase.

On the long-term perspective: In one to three years, instrument-integrated operating systems may become established as an option. We believe the value of display integration will increase if integration with driver assistance features progresses. We assess that coexistence of automakers’ proprietary systems and external systems will become the norm. Establishing frameworks for data management and division of responsibility will be a condition for wider adoption.

We present questions from the editorial team. There is the question of whether it is appropriate to entrust the core of vehicle operation to an external operating system. There is also the question of whether customizable instrument displays are compatible with safety. It is also asked who will be responsible for long-term maintenance and functionality in the used market. We believe examination of these issues will be necessary for future discussion.
