Forza Horizon 5 Tutorial: How to Create the Fastest Car in the Game (X999)


What is the fastest car in the Forza Horizon 5? This is the question we are answering today with the Lamborghini Sesto Element. According to expert Don Joewon Song, it is the most powerful car in the game, here we explain how to optimize it so that it hits your maximum speed.

When looking at the Forza Horizon 5 car list, it’s not hard to find some really fast cars. But the Youtuber apparently found the best of all, the one that definitely deserves its credit: the Lamborghini Sesto Elemento.

The car is classified as X999, that is, the highest level of the game. Other cars also obtain this maximum score, such as the Ferrari 599XX Evolution, the Maserati MC12 or even the McLaren P1. The X-class cars are therefore the fastest in the game, ahead of the S2-class cars. In total, 16 vehicles are rated X999 on the Forza Horizon 5 so far, but it will be imperative to have fun with the tweaks and improvements to reach that peak.

The Lamborghini Sesto Elemento is able to go from 0 to 100 km/h in 2.5 seconds thanks to its 570 hp V10 engine. In the video below, the fastest car in Forza Horizon 5 is capable of exceeding 410 km/h, an incredible speed for the game!

How to transform the Lamborghini Sesto Elemento into X999?

To achieve this, for example, you will have to buy the V12 Racing Engine for 50,000 credits. This increases the car’s top speed from 8.4 to 8.8. O turbo duplo has the same effect. You can also modify the front bumper to get better top speed, as well as the rear spoiler, which allows for better grip on offroad tracks.

In the engine menu, you must also access the valve part to buy the dedicated racing pack. This will allow you to go up to the maximum speed of 9.0. Then go to the engine block menu to exchange yours for one that is also dedicated to racing and that increases maximum speed to 9.2. It is also necessary to choose the cooling circuit more advanced, as well as other small settings available in the video above. Thus, you will go from an S2 998 car to an X 999 optimized to the maximum.
