Toyota Technology: Software, Features & Future Tech

Toyota's most important technology story right now is not an engine or a battery but a piece of software. Arene is the software development platform created by Woven by Toyota, the company's software subsidiary, and it is designed to turn Toyota's cars into what the industry calls software-defined vehicles. In a traditional car, features are tied tightly to the specific hardware that runs them, which makes updates slow and expensive. A software-defined approach separates the two, so that functions can be written once, reused across many vehicles and improved over time. Arene is Toyota's answer to how to build that capability at scale.

Toyota describes Arene as three connected packages. The first is the software development kit, which supports designing, coding, testing, deploying and maintaining vehicle software, and which separates software from hardware so that developers can reuse modular components across applications and vehicle models. The second is Arene Tools, which lets software be visualised, tested, validated and managed in virtual environments, reducing the need for physical prototypes. The third is Arene Data, which gathers and analyses driving data, with the customer's consent, to support over-the-air updates and continuing improvement. Together they cover the whole life of a feature, from the first line of code to the update that ships after the car is sold.

The first Toyota delivered to customers with features developed on Arene was the all-new RAV4, which went on sale in Japan on 21 May 2025. Toyota says the software kit was used to build the cockpit voice agent, the centre display and the latest generation of Toyota Safety Sense, while Arene Tools were used for advanced simulation of driving scenarios and safety functions. Woven also contributed artificial intelligence models for detecting surrounding objects and monitoring the driver's condition. The RAV4 uses a domain architecture, with separate computing for the driver assistance system and for the cockpit electronics, which is a stepping stone toward a more centralised design.

Why does this matter for an ordinary buyer? The answer is that a car's usefulness no longer ends on the day it leaves the factory. Features that run on a modern software platform can be refined after purchase, so a driver assistance function can get smoother, or a voice assistant can learn new commands, without a visit to a dealer. Toyota says Arene Data supports this by feeding real-world driving information, collected with consent, back into development, and the company states that the platform helps deliver new and improved features even after the vehicle leaves the factory. Over a ten-year ownership period, that could be a significant change in how a car ages.

Toyota has also signalled that Arene's scope will grow. Woven has said its tools will be applied to body electronics, steering and braking in future models with a more centralised electronic architecture, and the platform is expected to appear in Toyota's next-generation electric vehicles. This also ties into the company's work on custom semiconductors through a joint venture with Denso called Mirise, which reflects Toyota's recognition that controlling software and the chips that run it is becoming as strategically important as building excellent engines and transmissions.

It is worth keeping expectations realistic. Software-defined vehicles are a long-term transition, not a switch that flips overnight, and the first Arene-powered car is a first step, with Toyota itself describing it as the beginning of a journey. Details such as exactly which features will receive over-the-air updates, how often and on which markets will vary by model and region, so buyers should check the specifics for the vehicle they are considering. Even so, Arene is the clearest sign that Toyota intends to compete on software as well as on the mechanical quality it is famous for.

For most owners, the technology they touch every day is the multimedia system, and this is an area where Toyota has made rapid progress. The company's current system, called Toyota Audio Multimedia, replaced the older Entune generation and is built around a faster processor and a cleaner interface. An enhanced version debuted in the 2026 RAV4 and is set to roll out to more Toyota models later. It comes with a 10.5-inch touchscreen as standard and a 12.9-inch screen available on higher trims, a clear step up in size from the smaller displays that earlier Toyotas were criticised for.

A headline feature is the new voice assistant. Toyota built it in-house, and it now runs on the device itself rather than depending entirely on a cloud connection, which makes responses faster and keeps many functions working when mobile signal is weak. Drivers wake it with phrases such as “Hey Toyota,” “Hi Toyota” or “Okay Toyota,” and it can handle commands for navigation, climate and media. It is an example of how the Arene software kit, described above, feeds directly into the features a driver actually uses, since Toyota says the cockpit voice agent was developed on that platform.

Navigation is handled through Drive Connect, Toyota's connected-services package. Cloud-based navigation features, including points-of-interest search, weather cues and EV routing with charging stops, require an active trial or subscription, as do real-time traffic and the live-agent service. Full-screen navigation can also appear in the digital gauge cluster, keeping directions in the driver's line of sight. As with most manufacturers, the subscription model is worth understanding before you buy: a car may include a trial period, after which some conveniences require payment, and what is included varies by model, trim and market.

Smartphone integration is straightforward. The system supports wireless Apple CarPlay and Android Auto, so most drivers can connect their phone without a cable, and it keeps the familiar phone interface available alongside Toyota's own. The enhanced system is also Toyota's first to integrate 5G connectivity, powered by AT&T in the United States, which supports faster data for navigation, streaming and software updates. Toyota says the system will receive continual improvements, including through over-the-air updates, so the version in a new car should get better rather than stand still.

Beyond the dashboard, the Toyota app extends the car into the owner's phone. Depending on the model and subscription, remote connect features can include locking and unlocking, remote start, climate pre-conditioning and vehicle status checks, and some models support a digital key that lets a smartphone act as the key. Toyota publishes a feature-applicability chart for each model year because availability differs so much between vehicles, which is a useful reminder that not every Toyota has every feature. Always confirm the exact specification of the trim you are considering.

There is also a privacy angle that deserves a brief mention. Connected services collect data, and Toyota states that driving data used to improve its software is gathered with the customer's consent. Owners should read the data and privacy settings in the vehicle and the app, decide what to share, and understand what happens to a connected account when a car is sold. Handled sensibly, Toyota's connected technology adds genuine convenience and safety, but it works best when the owner knows exactly what has been switched on.

Underneath every modern Toyota sits a platform strategy called the Toyota New Global Architecture, or TNGA, first introduced with the fourth-generation Prius in 2015. TNGA is not a single platform but a philosophy for how Toyota designs and builds its vehicles: a common set of design principles that give every car a lower centre of gravity, a stiffer body structure and a more rigid driving feel, while allowing components to be shared across many models. The result is a lineup that feels more engaging to drive than Toyotas of earlier generations, and one that is easier and cheaper for the company to engineer.

TNGA also changed Toyota's engineering process. By grouping vehicles into families that share key components, the company can design a platform once and use it across everything from the compact Corolla to the larger Camry, RAV4 and Highlander. The same thinking drove the consolidation of Toyota's engine portfolio, which our Toyota engines guide covers in detail, with variations cut from more than 800 historical designs to fewer than 20 active platforms. Fewer designs mean more engineering effort per design, higher build quality and simpler supply chains, which feeds directly into the reliability record covered in our Toyota reliability guide.

For electric vehicles, Toyota has been developing an even more radical approach to manufacturing. In June 2023 the company announced plans for a next-generation battery-electric architecture built around gigacasting, a technique in which large sections of the body structure are cast as single pieces rather than assembled from many stamped and welded parts. Toyota said the BEV body would be built from three main modules at the front, centre and rear, which reduces the number of parts and the processes needed to assemble them. Toyota demonstrated a prototype production line in Japan in September 2023.

A second element of that plan is what Toyota calls self-propelled production. Instead of moving along a conventional conveyor, finished vehicles drive themselves through the assembly line under sensor guidance at very low speed, which Toyota says improves flexibility in how factory space is laid out and reduces the investment needed to build or modify a line. Toyota also described changes to casting itself, including reducing the time needed to change a casting mould from around 24 hours to about 20 minutes, according to reports on the demonstration. The aim is to lower both cost and complexity, which have been among the biggest barriers to making affordable electric cars.

Why does manufacturing technology belong in a guide about cars? Because it determines what the cars cost, how consistent they are and how quickly Toyota can respond when demand changes. A body made from fewer large castings has fewer joins and fewer places for tolerances to drift, and a flexible assembly line can switch between models more readily. Toyota's famous production discipline, which we covered in the reliability guide, is now being applied to the shift to electrification, with the goal of building electric vehicles with the same quality as its combustion and hybrid models.

As always, a caution about timelines is worth making. Toyota set ambitious targets in 2023, and as the electric vehicle market has developed, some of the dates the company announced then have moved. Manufacturing breakthroughs often take longer to reach showrooms than the initial announcements suggest. The sensible way to read this is as a direction of travel, with Toyota investing seriously in cheaper, simpler and more flexible vehicle production, and with the real-world results visible only as new models reach customers over the coming years.

If any single technology could change the future of Toyota's electric cars, it is the solid-state battery. Today's electric vehicles use lithium-ion cells that contain a liquid electrolyte, the material that carries charge between the electrodes. A solid-state battery replaces that liquid with a solid material, which in theory allows greater energy density, faster charging and improved safety, since a solid electrolyte is less prone to leaking or catching fire. The promise is a battery that is lighter, charges quicker and lasts longer than anything in production today, and Toyota has spent years pursuing it.

Toyota has publicly targeted the period from 2027 to 2028 for bringing solid-state batteries to market, and it has repeatedly described them as a cornerstone of its next-generation electric vehicles. The company has previously said that the technology could offer a range of roughly 745 miles and a recharge time of around ten minutes, although such figures are targets rather than demonstrated production results. Toyota has also been working with partners to build the supply chain that a new battery type would need before it can be produced in volume.

Two partnerships stand out. Toyota has worked with the energy and materials company Idemitsu Kosan on a sulphide-based solid electrolyte, with Idemitsu reportedly planning a facility to produce the key lithium sulphide material, scheduled to begin operating in 2027. In October 2025, Toyota also reportedly agreed to cooperate with Sumitomo Metal Mining on cathode materials for solid-state batteries. These are the kinds of unglamorous, supply-chain agreements that determine whether a laboratory breakthrough can become a product, and they suggest that Toyota is treating the technology as a serious industrial programme rather than a research project.

There are good reasons for caution, however. Solid-state batteries have been “a few years away” for a long time, and the engineering challenges are formidable. Solid electrolytes can be brittle and can develop cracks or poor contact with the electrodes as the battery charges and discharges, which reduces lifespan, and manufacturing them at low cost and high volume is an unsolved problem across the whole industry. Reports of launch timing have varied between 2026 and 2028, and only prototype battery packs have been demonstrated publicly, which means the promised figures should be treated as ambitions until they appear in production vehicles.

It is also worth understanding how this fits with Toyota's wider battery strategy. The company has long argued that no single technology will suit every market, and it continues to develop improved conventional lithium-ion batteries, hybrids and hydrogen alongside solid-state research. That is why the solid-state programme is best viewed as one element of a broader portfolio rather than a bet that replaces everything else, and it is one reason Toyota has been more cautious than some rivals about committing entirely to battery-electric vehicles.

For buyers, the practical message is to be patient. Nothing about Toyota's solid-state programme should change a purchase you are making today, because production-ready solid-state cars have not yet reached the market. For a deeper look at the electric and future models Toyota is preparing, including the vehicles most likely to benefit from new battery technology, see our dedicated guides, and treat any specific range or charging figure quoted in advance as a target rather than a promise.

Toyota's most advanced driver assistance technology goes by the name Toyota Teammate, with a Lexus-branded version called Lexus Teammate. The system was unveiled in April 2021 on the Lexus LS and the Toyota Mirai, where it was marketed under the name Advanced Drive. The name Teammate reflects Toyota's philosophy that the technology should work alongside the driver as a partner rather than replace them, and the company has been deliberate in describing the system as “automated” rather than “self-driving” or “autonomous.”

The technology is built on a much richer set of sensors than the standard Toyota Safety Sense package. Advanced Drive uses lidar, cameras and radar, combined with high-precision maps, and machine learning to interpret the road environment. It can handle highway scenarios including lane keeping, maintaining distance to other vehicles, lane splits, lane changes and overtaking, and it adds automated parking assistance that controls steering, braking, acceleration and gear changes. Over-the-air updates can add functionality after purchase, which is another way in which the software-defined approach described earlier shapes the car.

A key part of the design is the driver monitoring system. A camera, supplied by Aisin, watches the driver to confirm that they are attentive and ready to take over, and certain functions, such as lane changes, require the driver's confirmation. It reflects a deliberate decision to emphasise the human in the loop. Other suppliers include Denso, which provides the forward radar and stereo camera, with processing power from Nvidia and Renesas, illustrating how many partners contribute to a system of this complexity.

For the great majority of Toyota owners, the relevant technology is not Advanced Drive but the Toyota Safety Sense suite, which we cover in detail in our Toyota safety guide. The newest generation of Safety Sense includes features such as Lane Tracing Assist, Proactive Driving Assist and, on vehicles with a driver monitor camera, an Emergency Driving Stop System, and on the all-new RAV4 the latest Safety Sense was developed using the Arene platform. In effect, the capabilities showcased in flagship Lexus and Toyota vehicles filter down gradually into mainstream models, which is how most automotive technology reaches ordinary buyers.

It is important to be clear about what these systems are and are not. Even the most advanced Toyota technology is a driver assistance system, not a driverless car, and the driver remains responsible for the vehicle at all times. Operating conditions are limited, performance depends on road markings, weather and mapping coverage, and availability depends on the model and market, with the most advanced systems found only on selected, usually premium, vehicles. Toyota's stated goal is a future with zero traffic accidents, but its own cautious language shows how seriously it treats the gap between assistance and autonomy.

Looking ahead, Toyota's work in this area is conducted by its Woven by Toyota software arm and by the Toyota Research Institute, which focus on artificial intelligence, simulation and safer driving. Arene Tools allow driving scenarios to be simulated at scale, reducing reliance on costly real-world testing, and the lessons learned in premium models feed into the mass-market range. For buyers, the practical effect is that each new generation of Toyota's driver assistance tends to be more capable, smoother and more refined than the last, while remaining firmly a system that supports an attentive driver.

Perhaps the most ambitious technology project Toyota has ever attempted is not a car at all but a city. Woven City is a purpose-built test community at the foot of Mount Fuji in Susono City, Shizuoka Prefecture, Japan, on the former site of the Higashi-Fuji Plant. Toyota first announced the idea at the CES technology show in 2020, and it describes the site as a test course for mobility, a place where inventors can develop, test and validate new products and services in a real, lived-in environment rather than in a laboratory or on a closed test track.

The project is being built in phases. Construction of Phase 1, covering roughly 50,000 square metres, was completed in October 2024, and the first phase officially launched in September 2025. Toyota has said the full site is expected to reach around 708,000 square metres, with a total population of about 2,000 across all phases. Early residents are mainly Toyota and Woven by Toyota employees and their families, with a few hundred people expected in the first phase, and Toyota has said it plans to welcome the general public as participants from the 2026 financial year or later. The site has also received a LEED for Communities Platinum certification, the highest rank in that sustainability system.

Toyota uses two terms to describe the people involved. Residents are called “Weavers,” and external participants, including companies, startups, universities and research institutions, are called “Inventors,” who are invited to co-create and test their own products and services within the community. Confirmed Inventors have included companies such as Daikin Industries, DyDo DRINCO, Nissin Food Products and UCC Japan, working on themes from personalised indoor environments to food and retail experiences. Toyota's own software subsidiary also contributes, including its Arene platform.

The technology focus covers more than vehicles. Woven City is designed to test mobility, logistics, energy and information systems together, and reported areas of interest include infrastructure powered by hydrogen fuel cells, advanced robotics and the Arene software platform. The inclusion of hydrogen is consistent with Toyota's wider strategy, which we cover in our Toyota hydrogen cars guide, and the city offers a rare setting in which hydrogen supply, delivery robots and connected vehicles can be tested as one integrated system rather than as isolated products.

Why would a carmaker build a city? The reasoning is that many of the most promising technologies, such as automated driving, shared mobility and connected infrastructure, only reveal their problems when they interact with real people in everyday situations. A closed test track cannot reproduce the unpredictability of residents, deliveries, pedestrians and weather. By creating a place where thousands of people can eventually live and work, Toyota hopes to learn faster and refine technologies before they reach the wider market, much as a software company runs a beta programme before a full launch.

As with any experiment of this scale, it is sensible to treat the early claims with some patience. Woven City is a long-term programme, and its ultimate impact on the cars Toyota sells will take years to become clear. Residents numbers, schedules and technologies on trial may change as the project develops, and Toyota has not suggested that every idea tested there will reach production. Still, as a statement of intent, it shows how widely Toyota is thinking about the future of mobility, extending from the engine and the battery to the software, the infrastructure and the community in which cars are used.
