In-Vehicle Assistant Market Size - By Technology, By Component, By Vehicle, By Application, By Sales Channel, Growth Forecast, 2026-2035

In-Vehicle Assistant Market Size

The global in-vehicle assistant market size was estimated at USD 8.4 billion in 2025. The market is expected to grow from USD 9.2 billion in 2026 to USD 21.3 billion in 2035, at a CAGR of 9.7% according to latest report published by Global Market Insights Inc.

The rapid progression of the connected smart vehicle sector continues apace, largely due to an increase in demand from consumers for safe and easy hands-free interaction with their vehicles and a growing commitment from OEMs worldwide to produce significant numbers of both electric and automated products. Major automotive OEMs including Tesla, Mercedes-Benz, BMW, and emerging Chinese manufacturers like NIO and XPeng are deploying large language model (LLM)-powered voice assistants.
 

The rise of the multimodal Human-Machine Interfaces (HMI) market emerged as an extension of voice HMI. The increasing use of LLMs (Large Language Models) for development of gadgets, platforms, and technologies provided automakers with opportunities to create new HMI products that integrate two or more modes of input including gesture, touch, and voice. This has resulted in greater acceptance of the use of multimodal HMIs in both premium segments and lower-end models.
 

The COVID-19 pandemic had a significant but mixed impact on the In-Vehicle Assistants market. As governments across the globe enacted lockdowns to combat the spread of viruses, the production and sale of automobiles around the world were interrupted by supply chain issues resulting from the closure of factories, shortages of components, and other issues associated with the pandemic. As such, the integration of voice assistants into new vehicles was temporarily hindered by these supply chain disruptions.
 

The Asia Pacific region has the highest market share of the global automotive product assistants. This growth is driven by total production volume by the thirty million annual vehicle manufacturing in China, with the implementation of the Government's Intelligent Connected Vehicle (ICV) mandate to ensure a voice-based emergency. The region has also developed robust domestic Artificial Intelligence (AI) platforms with low-cost solutions from Baidu DuerOS, Alibaba AliGenie, and Tencent Xiaowei with 94%+ accuracy scores for Mandarins.
 

Latin America is growing the fastest region, which is experiencing rapid growth in the number of voice assistants being used. Localization investment is expected to increase as local economic conditions become more stable and the overall economy stabilizes. Brazil is the largest economy in Latin America and has significant international companies currently working to develop and implement new Portuguese language localization capabilities on the voice assistant platforms of Google, Amazon, and Cerence.
 

In-Vehicle Assistant Market Trends

The integration of generative artificial intelligence and large language models represents the most drastic change to date to the tech space that enables in-vehicle assistant’s technological capabilities and user experience. Tesla's use of the GPT-powered conversational AI across its Model S, Model 3, Model X and Model Y enables users to interact with their vehicle through natural language both for control of the vehicle and for navigation via voice commands.
 

The MBUX Hyperscreen in the EQS and EQE electric cars from Mercedes-Benz uses NVIDIA DRIVE AGX Orin chips to produce 254 TOPS (trillion operations/s). The combination of the chips with the MBUX allows for the ability to create real-time large language models for conversational exchanges, providing ongoing context and adapting responses based on user preferences.
 

Luxury or premium vehicles have been at the forefront of the AI integration trend. Currently this trend moved into lower-cost vehicles with the development of CARIAD (the Volkswagen Group's software platform) that will support hundreds of thousands of connected vehicles by 2030. The CARIAD platform has developed scalable voice-based artificial intelligence solutions for different manufacturers within the Volkswagen Group for their brand such as Volkswagen, Audi, Porsche and Skoda.
 

The implementation of a cloud-based connectivity infrastructure to support real-time data synchronization and over-the-air software updates is a major transformation that changes the way the in-vehicle assistant operates. The Ultifi platform, which was introduced by General Motors in 2023, offers OTA software updates to all 2024 model year Chevrolet, GMC, Buick & Cadillac vehicles along with the in-vehicle voice assistant.
 

By integrating voice, touch and gesture inputs into a new form of HMI, we are moving from the traditional single-mode vehicle interface to a more flexible multi-channel communication model between the vehicle and its occupants. The Mercedes-Benz MBUX represents the best example of this new form of multimodal leadership, as it combines a "Hey Mercedes" voice command with a touchscreen interface.
