James Cryer, Production Engineering Manager at Astemo UK, said: “[It is] great to have the PICOW Engineering team on board with our exciting project!”

Astemo in recent years

In January 2021, Hitachi Automotive Systems, Keihin, Showa, and Nissin Kogyo completed a business merger and began their journey as the global mega-supplier “Hitachi Astemo”. 

Hitachi Astemo officially changed its name to Astemo on April 1, 2025.

The company supplies products like automotive powertrain systems, chassis systems, autonomous driving/advanced driving assistance systems (AD/ADAS), and motorcycle systems.

This new expansion initiative, which aims to strengthen Astemo UK’s electrification business, has been approved by the UK Government’s Automotive Transformation Fund in the UK.
