Renesas has begun sampling Gen 5 silicon and is now offering full evaluation boards and the R-Car Open Access (RoX) Whitebox Software Development Kit (SDK) as part of the next phase of development. Renesas is also driving deeper collaboration with customers and partners to accelerate adoption. At CES 2026, Renesas will showcase AI-powered multi-domain demonstrations of the R-Car X5H in action.
The R-Car X5H utilizes one of the industry’s most advanced process nodes, delivering the highest levels of integration, performance and power efficiency with up to 35 percent lower power consumption than previous 5nm solutions. As AI becomes an integral part of next-generation SDVs, the SoC provides powerful centralized computing power for multiple automotive domains and the flexibility to scale AI performance using chiplet extensions. It delivers AI performance of up to 400 TOPS, with chiplets boosting acceleration by four times or more. It also features GPU performance of 4 TFLOPS* for high-end graphics and over 1,000k DMIPS provided by 32 Arm® Cortex®-A720AE CPU cores and six Cortex-R52 lockstep cores with ASIL D support. By utilizing mixed-criticality technology, the SoC performs advanced functions in multiple areas without compromising safety.
As hardware and software become more tightly integrated at an early stage of development to support complex E/E architectures, Renesas is adding new features to the RoX development platform. RoX greatly simplifies development by combining all the essential hardware, operating system, software and tool components required for rapid development of next-generation vehicles with seamless software updates.
Accelerating automotive innovation with an open, scalable RoX Whitebox SDK
To accelerate time-to-market, Renesas now offers the RoX Whitebox Software Development Kit (SDK) for the R-Car X5H, an open platform based on Linux, Android and the XEN hypervisor. Additional support for partner operating systems and solutions is available, including AUTOSAR, EB corbos Linux, QNX, Red Hat and SafeRTOS. Developers can start development immediately with the SDK to create ADAS, L3/L4 autonomy, intelligent cockpit and gateway systems. An integrated stack of AI and ADAS software enables real-time perception and sensor fusion, while generative AI and Large Language Models (LLMs) enable intelligent human-machine interaction for next-generation AI cockpits. The SDK integrates production-ready application software stacks from leading partners such as Candera, DSP Concepts, Nullmax, Smart Eye, STRADVISION and ThunderSoft, supporting end-to-end development of modern automotive software architectures and faster time-to-market.
“Since the launch of our most advanced R-Car device last year, we have consistently focused on developing market-ready solutions, including delivering silicon samples to customers earlier this year,” said Vivek Bhan, Senior Vice President and General Manager of High Performance Computing at Renesas. “Working with OEMs, Tier 1 suppliers and partners, we are currently rolling out a complete development system that will power the next generation of software-defined vehicles. These intelligent computing platforms provide a smarter, safer and more connected driving experience and are designed to grow with the future demands of AI mobility.”
“Integrating Renesas’ R-Car X5 generation into our high-performance computing portfolio is a logical next step that builds on our existing collaboration,” said Christian Koepp, Senior Vice President Compute Performance at Bosch’s Cross-Domain Computing Solutions Division. “We look forward to showcasing this powerful solution with the Renesas X5H SoC at CES 2026 and demonstrating its fusion capabilities in multiple vehicle areas, including video perception for advanced driver assistance systems.”
“Innovative system-on-chip technology like Renesas’ R-Car X5H is paving the way for ZF’s software-defined vehicle strategy,” said Dr. Christian Brenneke, head of the Electronics & ADAS division at ZF. “By combining Renesas’ R-Car X5H with our ADAS software solutions, we can offer full-stack ADAS functions with high computing power and scalability. The joint platform combines radar localization and HD mapping to enable accurate perception and positioning for reliable ADAS performance. At CES 2026, we will showcase our joint ADAS solution.”
First Fusion demo on R-Car X5H with partner solutions at CES 2026
Renesas will debut the capabilities of the R-Car X5H in an invitation-only series of demos at CES 2026. For more information on attending this event, please contact sales at: CES26_Info@lm.renesas.com.
The new multi-domain demo will scale up from R-Car Gen 4 to the next generation R-Car X5H on the RoX platform, integrating ADAS and IVI stacks, RTOS and edge AI functionality on Linux and Android with XEN hypervisor virtualization. The platform supports input from eight high-resolution cameras and up to eight displays with resolutions up to 8K2K, providing immersive visualization and robust sensor integration for next-generation SDVs. Combined with the RoX Whitebox SDK and production-ready software stacks from partners, the platform is designed for real-world use in various automotive domains.
