The seasonal Festival events in Forza Horizon 6 regularly feature fresh objectives that let players unlock exclusive vehicles, Credits, and other rewards. While some challenges focus on treasure hunts or taking photos in specific locations, others require pulling off driving skills with certain types of cars. One of these tasks involves performing a Barrel Roll Skill. Here's the quickest way to get it done.
A Barrel Roll Skill is awarded when your vehicle completes one full rotation in the air before landing. Simply jumping off a ramp isn't enough. The car must spin completely around its horizontal axis and finish a full 360-degree roll.
One of the most reliable locations for this stunt is Tokyo Dockyards. The area features two ramps that make barrel rolls much easier than in most other parts of the map. The first and most convenient option is the Tokyo City Dockside Danger Sign. Build up as much speed as possible across the docks, then line your car up so that one set of wheels is slightly off the side of the ramp just before takeoff.

Doing this shifts the car's weight to one side, allowing momentum to carry it through a complete barrel roll once it leaves the ramp.

A second suitable ramp is located directly behind the Danger Sign near a group of shipping containers and a large cargo warehouse. This jump is a bit more challenging because you'll need to avoid hitting the containers after landing. Crashing into them can break your skill chain and may prevent the Barrel Roll Skill from counting.

If you're completing the Rolling in the Jeep daily challenge, the 2018 Jeep Grand Cherokee Trackhawk is the recommended choice. It costs 72,000 Credits in the Autoshow and offers excellent speed and acceleration, making it much easier to perform a successful barrel roll.
Completing the Rolling in the Jeep challenge rewards you with 5,000 Credits and one Season Point that counts toward the Spring seasonal rewards.
As a Reminder, Forza Horizon 6 Receives Massive Series 3 Update and New Italian Car Pack.
