The title of the fastest car in Forza Horizon 5, based on the highest tested top speed, currently belongs to the 2019 Rimac Concept Two. This all-electric hypercar can reach a staggering 258 mph (415 km/h) on the game's long highway straight, outperforming even legendary supercars. Its incredible speed comes from a quad-motor electric powertrain delivering a massive 1914 horsepower and 1696 lb-ft of instant torque, allowing for explosive acceleration.
However, "fastest" can mean different things. While the Rimac reigns in pure top speed, other cars excel in different metrics. For 0-60 mph acceleration, the 2018 Ferrari #25 Corse Clienti 488 Challenge is nearly untouchable. For the fastest lap times around a technical circuit, cars with superior handling and downforce, like the 2018 Mosler MT900 GT3, are often better choices. The car's Performance Index (PI) score is a good starting point, but it balances speed, acceleration, braking, and handling. A car with a slightly lower PI might be faster in a specific discipline.
Here’s a comparison of some of the top contenders:
| Car Model | Top Speed (Approx.) | 0-60 mph (Approx.) | Key Strength |
|---|---|---|---|
| 2019 Rimac Concept Two | 258 mph (415 km/h) | 2.5 seconds | Pure Top Speed, Electric Acceleration |
| 2011 Koenigsegg Agera RS | 255 mph (410 km/h) | 2.8 seconds | High-Speed Stability |
| 2010 Pagani Zonda R | 217 mph (349 km/h) | 2.7 seconds | Circuit Lap Times, Downforce |
| 2018 Mosler MT900 GT3 | 220 mph (354 km/h) | 2.9 seconds | Balanced Track Performance |
| 2018 Ferrari #25 488 Challenge | 200 mph (322 km/h) | 2.1 seconds | Extreme Acceleration, Cornering |
Ultimately, the best car depends on the event. For top speed challenges, the Rimac is your champion. For racing on curvy tracks, you'll want a car that can maintain high speeds through corners, not just on the straights.
