G10
___
G10 is the first electric car designed and build by AAU Racing after 9 combustion cars in the last two decades. The car brought in high-voltage engineering from the Energy institute of Aalborg Univeristy, expanding the amount of students and studies participating in the project.
Story Behind G10
G10 is the first electirc racecar design and build by AAU Racing. Initial design began in the fall of 2022 and has involved a lot of new technologies and infrastructure. The battery is fully custom with self-developed Accumulator Management System (AMS). A safe High-Voltage container was build remote from buildings for building, testing, and storing the battery in. The main focus was to build a safe and reliable car for the first year, to enable as much testing of the new systems as possible. The car first participated in the FSG2025 competition. While it didn't get to drive, it made it through Mechanical and Accumulator scrutineering, only missing the Electrical scrutineering. This was super impressive considering first year electric cars and the feedback from competition officials confirmed the concept and excecution of the car to be safe and a good approach going forward.

High-Voltage Systems
For G10, the first high-voltage battery was developed. Consisting of 5 segments configured in a 28s3p connected in series providing 588 V and 80 kW limited output. Each segment is seperated by a firewall and a high-voltage components compartment exist in the front to house the power electronics. The battery case is constructed out of lasercut aluminium panels welded together, glued with nomex paper on the inside to isolate the case. The battery is connected to the Bamocar D3 inverter and then the Emrax 228 motor to provide power.
Low-Voltage Electronics
Switching to an electric car for G10, many additional electronics systems had to be developed like the Accumulator Management Systems (AMS). All electronic boards on the vehicle are custom designed and manufactured enabling fine-tuning and optimization of the whole electronics system.
Chassis
The chassis is a traditional tubular steel space frame chassis. Most of the G9 front concept was carried over while focusing on the rear end design, accomodating the new battery, inverter, and electric motor & the switch from pull- to push-rod rear suspension.
Due to stricter chassis rules for electric cars compared to combustion cars, the weight increased from xx kg to xx kg.
The chassis was lasercut by JPBC and installed in a custom designed steel fixture and welded by team members. This fixture ensures correct positioning and high accuracy of the chassis.
The chassis uses an aluminium anti-intrusion plate (AIP) and a standard aluminium impact attenuator (IA).
Suspension
The G10 car uses double-wishbone front pull-rod and rear push-rod suspension. The focus was on reducing weight while keeping the complexity of design and production close to the previous car to reduce risk, as the focus was on proving the new high-voltage system.
Some of the the highlights include switching two floating brake discs, switching to titanium wheelstuds and in total reducing weight by xx kg.
Drivetrain
The drivetrain had the complexity of switching from a combustion engine to an electric motor. Therefore, the choice was made to keep the current differential mounting setup concept and connecting it to the electric motor.
Combined motor mounts were designed as well as an aluminium axle mounted to the electric motor and a high-strength steel sprocket mounted to that. The chain had to be beefed up due to the increased torque from the motor compared to the combustion engine.
Aerodynamics
G10 being the first car developed from the ground up with aerodynamics, and only the second car with aerodynamics, the focus was on improving downforce while adding a bit more complexity to the design. The car features and front & rear wing, flat floor and a diffuser. This helped achieve an increase in downforce. Additionally, focus was on improving production capabilities by acquiring a Bertha 1500 CNC from Frislev CNC.
The wings feature internal carbon fibre skeleton structure achieving a high stiffness-to-weight ratio.
