Forza Horizon 5

TO BE CLEAR, THIS IS 5 UPGRADES ON 5 DIFFERENT CARS! NOT 5 UPGRADES ON ONE CAR!

Go to the Horizon Test Track located near the main Horizon Festival. Start the event and go to Solo.

Once in, pick ANY car and load in.

Once the cut scene plays and you have control of the car, press the button to go into the upgrade menu. This is the same menu as the performance upgrade menu at the festival site.

Pick any tile and any upgrade and then back out to the point where you have control of the car.

Once you have control of the car, you do not need to drive anywhere. Simply press and select the option to quit and apply the upgrade. You will be prompted with another menu. Select the first option to install the upgrade and you will leave the test track

Repeat 4 more times for the achievement. Should take 5-10 minutes.

There is also a trackable accolade for this that can be pinned to your screen. To do this, press to pause the game, select Accolades and then press or twice to go over to the Creative tile and press . Press twice and go over to the Test Track tab. The accolade is located first column and second row from the top. Hover over the accolade and press the button to pin this to your screen.
