Deefholt Dynamics 2025: Season Kickoff with Innovation

Report on the Start of the 2025 Season – Deefholt Dynamics

First of all, I would like to sincerely thank you on behalf of our entire team for the collaboration we’ve shared so far. Without your valuable support over the past years, our successes would not have been possible.

As in previous years, we—students from PHWT in Diepholz—are once again dedicating our one-year project study to developing a new race car in order to participate in the globally renowned engineering competition, Formula Student. This year, we will take part in events in the Netherlands, Spain, and Germany.

Our 2025 team consists of 49 committed students from the fields of Mechanical Engineering, Industrial Engineering, Electrical Engineering, and Mechatronics, all determined to design a race car that is even more powerful and innovative.

Every year presents new challenges as we work to further develop and enhance the competitiveness of our vehicle. The regulations demand significant changes to nearly every component, pushing us to constantly develop innovative solutions. This season, our main focus is a complete overhaul of the chassis. By switching from 13-inch to 10-inch tires, we reduce unsprung mass, significantly improving driving dynamics. This requires a full redesign and fabrication of the chassis, which entails extensive development work and the production of many custom-made parts.

We are also continuing to use a monocoque chassis, which is being completely rebuilt from the ground up and will weigh only about 22 kilograms once finished. Since the monocoque is made of carbon fiber, it also represents a major cost factor.

Our vehicle from last season had a power output of up to 80 kW, weighed approximately 210 kg (excluding the driver), and reached a top speed of about 125 km/h. It accelerated from 0 to 100 km/h in around 4.4 seconds. In addition to mechanical improvements, we are also optimizing the electric drivetrain and battery management system to further increase efficiency and performance.

Looking ahead, we already have plans for further optimizations. In 2026, we intend to transition to an all-wheel-drive system. For this, we will be developing four planetary gearboxes, each integrated directly into a wheel.

We are grateful to have Eurocircuits as a strong partner by our side and look forward to shaping another successful season together. Especially as electronics play an increasingly important role in our project, our collaboration with Eurocircuits is of particular value to us.
