The fastest cars in Forza Horizon 5 can meet speeds that players can only dream of at the start of the game, and the extreme speeds they can reach can be a boon whether on the road or off.
This list includes only the cars that can go over 400 km/h or 250 m/h, which is the minimum for extreme track racing. The top speed parameters below indicate the performance of each vehicle in their vanilla versions, without being tuned.
Of course, you can boost the speed of these cars even further by tuning them in the in-game garage.
