If you want to complete the Forza Horizon 6’s Danger Sign Airfield Takeoff challenge, you will need a vehicle that can be used for jumping. Below is an overview of the A700 Japanese Vehicle requirements as well as recommended vehicles (like the Honda E and Toyota GR86) with information on how you need to go for successfully completing the jump and finishing the challenge.
Challenge Requirements

The car must belong to an A700 class and be made by a Japanese car company to achieve success with the Danger Sign Airfield Takeoff challenge. The player must utilize either Honda, Toyota, Nissan, or Mazda, and will want their car to be as light as possible without sacrificing strength as this will allow the vehicle to carry its weight while in flight.
Recommended Car and Tune

The 2022 Toyota GR86 is one of the cars that can be used to accomplish the task in this event and it is also listed as part of Series 1 Week 1 weekly challenges. You will need to have a tuning on your vehicle that will allow you to cover enough distance to complete the Danger Sign.
Another option could be the Honda E, when you use an A700 tune on it, it has the possibility of accomplishing the same distance for the challenge.
How to Complete the Danger Sign


Drive to the marked road within the Ito region after you have installed the tune and equipped your vehicle; approach the Danger Sign and go fast enough to jump approximately 225 meters (minimum jump distance required is 212 meters) to complete the challenge. Completing this challenge successfully will give you a free wheel spin.
