Honda rejoins Formula 1 this year as a power unit supplier with the Aston Martin team. Heading up its trackside operations is Shintaro Orihara, who has been the Japanese manufacturer for over 20 years.
You’ve worked at Honda for decades now, why did you want to join the company in the first place?
When I was in junior high school, I watched F1 on TV and something that stood out were the McLarens with their Honda-powered cars. From that moment onwards, I knew that I wanted to join Honda and be a part of this incredible sport. I started there in 2003 and, for the first 10 years, I worked on road-going projects. Despite this, my love and passion for F1 didn’t fade and the hard work paid off. In 2013, I transferred to the racing side of the business and reached my dreams. During this time, I could learn the tricks of F1 engineering and live some intense moments of adversity but ultimately some glorious memories and wonderful times. I can confidently say that Honda and F1 are a part of my life.
What are your responsibilities as F1 Trackside General Manager and Chief Engineer?
My role is vast and varied but, ultimately, I make the final decisions at the track relating to the power unit. I also manage all the trackside members from Honda Racing Corporation from a management viewpoint to make sure that our power units are ready.
Before departing for the race, we have a series of meetings with our colleagues in Sakura in Japan to check the situation and plan for the event. Usually, we travel early in the week so that when we arrive at track, the engine conditions after maintenance can be checked. On site, I will fine tune the plan with the engineers for the weekend, evaluating our options and scenarios depending on the conditions. Once we’ve done this, there’ll be a meeting with Aston Martin Aramco Formula One™ Team engineers to go through every detail, ensuring we’re fully integrated.
When the sessions start, the car’s PU is mainly operated by other Honda personnel. It’s my job to look at the big picture and what is happening overall. I will be making the decisions and communicating with the team via radio.
At the end of each day, we’ll hold an internal PU meeting on site and with our colleagues in the control room in Sakura. We will review what happened and put countermeasures in place if we encountered any issues. This is then reported to and discussed with the team, to make sure we’re aligned.
The Aston Martin Aramco Formula One Team is a key component in Honda’s Formula 1 activity. What work do you do with them? What are the targets?
2026 is the first year that we’re learning with Aston Martin Aramco at the track. Although the partnership was announced in 2023, everything has been based on theory and simulations, so there is a lot of anticipation for testing.
So, the first target is to build the fundamental relationship between the two parties trackside and second is to accumulate mileage and gather data, understanding how the RA626H power unit works in the AMR26.
What are your thoughts ahead of the first official F1 test in Bahrain?
It’s been a long time coming, quite frankly speaking. Years of development and hard work culminates with this. Sakura, HRC UK and Aston Martin Aramco have been working tirelessly to develop, plan and build.
The Barcelona Shakedown was a pivotal moment in our relationship and a good step in the right direction. Our next target is to accumulate mileage with our power unit to confirm engine reliability and to check all functions.
We’re looking forward to seeing how the package behaves – car and power unit – as one machine.
