Key Points
- You can purchase most car upgrades within the Garage.
- You will also require the right cars that will have these upgrades listed.
- Once you have acquired the right car, all you need to do is find the attachments and purchase them to complete the challenge.
Car challenges in Forza Horizon 6 are required if you are going for the final reward for this section. Plus, you get to discover all new attachments that will make your car faster and better at races. But if you are on a budget, then you need to handpick the required cars for the challenges and use the right upgrades on them.

How to Get Motor, Battery, and Supercharger Upgrades in Forza Horizon 6
While completing the many Car Upgrade challenges, you need to figure out the best and cheapest car to add the extra attachments without burning a hole in your pocket. With some help, I could figure out the best way to complete the two more complicated car upgrade challenges in the game.
How to Purchase and Install a Motor and Battery Swap

For this particular upgrade challenge, I went ahead and bought the cheapest vehicle available in the market. You could go for either the 2022 Wuling Mini EV, Honda E 2022, or any other cheap car that fits your budget. After that, head over to your Garage and select the Cars tab, and select Upgrades and Tuning.
Select the Custom Upgrades option and go to the Body Kits and Conversions option. Over here, you will find the Motor and Battery Swap option, so select it and pick any new motor to be installed in the car. You can switch between all available motors and check out their stats at the bottom of the screen.
After that, go back to the Upgrade Shop option and select the rightmost bottom corner option called Motor and Battery. Pick any part here and have it installed in your car to complete the challenge.
How to Get the Supercharger DSC and CSC
The cheapest car option for me that helped complete this challenge was the 2024 Ford Mustang Dark Horse. Then, head over to the Upgrades and Tuning section under the Cars tab and select Custom Upgrades.
Select the Body Kits and Conversions option, then select Aspiration. Over here, select the Centrifugal Supercharger and the Positive – Displacement Supercharger. Add these to your car and confirm the selection to complete these upgrade challenges too.
