TIER IV and HORIBA MIRA collaborate to fuel autonomous driving deployments in UK and Europe

TOKYO, Nov. 25, 2025 /PRNewswire/ -- TIER IV, the pioneering force behind open-source software for autonomous driving, and HORIBA MIRA, a UK-based provider of cutting-edge engineering, research and test services, are working together to accelerate the development of autonomous driving technologies in the UK and Europe. Through this collaboration, TIER IV will expand the deployment of its autonomous driving platforms in the region, with HORIBA MIRA providing access to its facilities and engineering expertise.

TIER IV will deliver software and hardware solutions – including its autonomous driving system, Minibus 2.0 electric vehicle, sensor packages, and operational support – while HORIBA MIRA will provide services for localization and safety validation of the software and hardware. HORIBA MIRA will also provide engineering support to ensure compliance with local regulatory and operational requirements.

The collaboration's first project will see the deployment of an autonomous bus on HORIBA MIRA's proving ground, laying the groundwork for future Level 4 operations at its UK technology hub.

With a strong track record of Level 4 autonomous vehicle deployments across Japan, TIER IV aims to share its technical expertise with municipalities, transport operators, and vehicle manufacturers throughout Europe. TIER IV's autonomous driving system supports a wide range of use cases, from off-road dump trucks to factory logistics, and regional partnerships will help extend deployments into new environments.

"We are delighted to join forces with HORIBA MIRA to accelerate the deployment of autonomous driving technologies across the UK and Europe," said TIER IV COO Ko Miyoshi.  "By combining our advanced platforms with HORIBA MIRA's world-leading engineering and validation expertise, we aim to accelerate the realization of safe, reliable, and sustainable mobility solutions tailored to local needs. This collaboration marks an important step toward our shared vision of making autonomous driving accessible to all."

"At HORIBA MIRA, we've made significant investments in autonomous vehicle technologies over the past several years to help enable safe and scalable deployment across Europe," said Alastair Evanson, head of business development and commercial operations. "Collaborating with TIER IV on this project is a natural extension of our commitment to supporting innovation in the sector, and we're pleased to provide the engineering and testing expertise needed to help localize their technology for European environments."
