Summary: TIER IV is collaborating with Renesas to build an open AI-native computing platform for software-defined vehicles, pairing the Autoware open-source autonomous driving stack and TIER IV’s reference AI models with the R-Car Gen 5 family of automotive system-on-chips.
Key engineering takeaway: R-Car Gen 5 becomes one of the primary reference computing platforms for Autoware, and TIER IV plans to deploy its end-to-end autonomous driving AI models on the same silicon. The stated scope spans Level 2+/2++ advanced driver assistance through to Level 4. Beyond current SoCs, TIER IV says it is developing AI accelerators optimised for transformer-based driving models, plus LiDAR and 4D radar sensing. A working demonstration on the R-Car X5H is scheduled for Automotive World 2026 at Makuhari Messe, 9 to 11 September.
Why it matters: Running one software stack across assistance-grade and Level 4 workloads on a single SoC family is the reuse argument OEMs and tier ones have been pressing for, because it avoids maintaining separate perception and planning builds per programme tier. Because the stack is an open AI-native computing platform built on Autoware, the integration work is visible to anyone already developing against it rather than locked inside a single supplier’s toolchain.
TIER IV, the pioneering force behind open-source software for autonomous driving, is collaborating with Renesas Electronics Corporation to build an open AI-native computing platform for software-defined vehicles (SDVs). The collaboration combines TIER IV’s autonomous driving software technologies such as its reference AI models as well as Autoware, the world’s leading open-source software for autonomous driving, with Renesas’ next-generation R-Car automotive system-on-chips (SoCs) to deliver scalable solutions spanning Level 2+/2++ advanced driver assistance through Level 4 autonomous driving. Together, this collaboration aims to establish an open hardware and software platform that enables the continuous evolution of AI-powered vehicles.
The automotive industry is entering the era of SDVs, where vehicle capabilities are increasingly determined by software, AI and high-performance computing rather than fixed-function hardware alone. At the same time, end-to-end (E2E) AI models are emerging as a new foundation for autonomous driving, while automotive computing platforms are evolving rapidly to support increasingly demanding AI workloads. Delivering production-ready autonomous driving therefore requires close integration between AI software, system software and automotive processors.
As the key developer of Autoware, TIER IV initiated the collaboration with Renesas to further expand the open ecosystem and advance safer, more intelligent and continuously evolving mobility.
Adopting R-Car Gen 5 As An AI-Native Computing Platform
TIER IV will adopt Renesas’ R-Car Gen 5 as one of the primary reference computing platforms for Autoware and future AI-native autonomous driving technologies.
The two companies will jointly optimize and promote this integrated hardware and software platform for automakers and Tier 1 suppliers worldwide, enabling faster development and deployment of SDVs.
Porting Autoware And Reference AI Models To The SoCs
TIER IV will port and optimize Autoware on Renesas’ R-Car Gen 5 automotive SoCs. Building on this software foundation, TIER IV also plans to deploy its reference AI models, E2E autonomous driving AI models, on R-Car Gen 5.
By combining conventional autonomous driving software with AI-native driving models on a common computing platform, the joint development aims to deliver highly scalable autonomous driving solutions covering both today’s production advanced driver-assistance systems and future Level 4 autonomous driving systems.
Looking beyond current-generation automotive SoCs, TIER IV is developing AI accelerators optimized for transformer-based autonomous driving AI as well as next-generation sensing technologies including LiDAR and 4D radar.
Demonstration At Automotive World 2026
TIER IV plans to demonstrate Autoware and its reference AI models running on Renesas’ R-Car X5H at Automotive World 2026, which is taking place September 9-11 at Makuhari Messe in the Tokyo metropolitan area. The demonstration will showcase the integration of open autonomous driving software, AI-native driving models and automotive-grade computing on a unified platform.
What TIER IV And Renesas Said
SDVs require more than just powerful AI models. They also require computing platforms that allow those models to run efficiently, safely and at scale in production vehicles. We are excited to deepen our collaboration with Renesas to build an open AI-native computing platform by combining Autoware, our reference AI models and Renesas’ next-generation R-Car automotive SoCs. We will continue expanding the open-source ecosystem centered on Autoware while accelerating the deployment of scalable autonomous driving solutions from Level 2+/2++ to Level 4.
Shinpei Kato, founder and CEO of TIER IV
We are delighted to evolve the relationship with TIER IV into a full business collaboration. R-Car Gen 5 represents our vision for a new generation of automotive computing, where software, AI and vehicle intelligence must work together on a common platform. With our collaboration with TIER IV, we are helping bring that vision to life.

AI-Native Computing Platform FAQ
What is an AI-native computing platform?
An AI-native computing platform is a vehicle compute stack built around AI models as the primary workload, integrating the automotive system-on-chip, the system software and the driving models so that end-to-end AI can run efficiently in a production vehicle rather than only on development hardware.
How does the TIER IV and Renesas collaboration work?
TIER IV will adopt Renesas’ R-Car Gen 5 as one of the primary reference computing platforms for Autoware, port and optimise Autoware on those SoCs, and plans to deploy its reference AI models on the same silicon. The two companies will jointly optimise and promote the combined hardware and software platform for automakers and Tier 1 suppliers.
What is Autoware?
Autoware is open-source software for autonomous driving, described by TIER IV as the world’s leading open-source stack for the field. TIER IV is its key developer, and it is a registered trademark of the Autoware Foundation.
What levels of autonomy does the platform target?
The stated scope runs from Level 2+/2++ advanced driver assistance through to Level 4 autonomous driving, on a common computing platform.
When and where is the platform being demonstrated?
TIER IV plans to demonstrate Autoware and its reference AI models running on Renesas’ R-Car X5H at Automotive World 2026, held 9 to 11 September at Makuhari Messe in the Tokyo metropolitan area.
