Forza Horizon 5 has more than 500 cars available, and each car has the potential to become faster after upgrades. With so many cars available, it can be difficult to track down which car is the fastest vehicle in Forza Horizon 5. Additionally, some of the fastest cars in Forza Horizon 5 can cost quite a few credits, ranging anywhere from the low millions to more than 20 million credits. Building the fastest car can quickly become just as time-consuming as it is costly.

Before upgrades, the 2020 Koenigsegg Jesko is considered to be the fastest car in Forza Horizon 5. In fact, most Koenigsegg cars are among Forza Horizon 5's fastest cars, and this particular model costs players 2,800,000 credits. Before upgrades, the 2020 Jesko is already a speed demon-reaching 303 mph at its peak. The 2020 Koenigsegg Jesko was designed specifically to break the 300 mph barrier in Forza Horizon 5.

The 2020 Koenigsegg Jesko is still considered to be the fastest car in Forza Horizon 5 after receiving upgrades, with the potential to reach speeds near 310 mph. Although the Jesko is faster than every car in Forza Horizon 5, the Koenigsegg cars at large suffer from being able to reach their top speeds as quickly as some of the other cars like the 2019 Rimac Concept Two or the 1997 Lamborghini Diablo GTR. Nonetheless, the Koenigsegg Jesko outshines every car in Forza Horizon 5 once it has the chance to reach its top speed. The necessary upgrades to the 2020 Koenigsegg Jesko will thankfully cost no more than 37,850 credits.

To maximize the speed of the 2020 Koenigsegg Jesko, players will want to install the following upgrades:

  • AWD Drivetrain
  • Race Twin Turbo Engine
  • Race Weight Reduction
  • Race Transmission: 7 Speed
  • Race Driveline
  • Race Differential
  • Slick Race Tire Compound
  • 295 MM Front Tires
  • 355 MM Rear Tires
  • Upgraded Front Track Width
  • Upgraded Rear Track Width

In all cases where players are trying to build the fastest version of their car with upgrades in Forza Horizon 5, race upgrades and upgrades that allow the car to reach its maximum horsepower are always the way to go. Lightening the weight of the car can also improve its launch, speed, and acceleration stats. All three of these stats play into how a car will perform in different types of races in Forza Horizon 5, like drag or street races. For example, the 1997 Lamborghini Diablo GTR is arguably the best car to use for drag races because of these stats, but it doesn't come close to the top speed of the 2020 Koenigsegg Jesko in Forza Horizon 5.
