2. Mosler MT900S

Engine | 7.0L Supercharged V8 |

Engine | 4.7L Naturally-Aspirated V8 |
Top Speed | 285 mph |
Horsepower | 400 BHP |
Torque | 332 LB-FT |
Weight | 1300 lbs |
The Shelby Monaco King Cobra is still a terrifyingly fast car, even though it is at least 50 years old. It features top-tier acceleration and launch, allowing it to reach speeds of 280-289 mph easily. According to the official description, this 1963 classic can easily compete with the flashier supercars of the present day, which boasts a “screaming 289 V8 and pumping out 400 hp.”
Thanks to its excellent launch and acceleration, this small car can get off to a fast start. With improvements and calibration, it has reportedly reached speeds of up to 285 mph, the third-fastest car in Forza Horizon 4. The best aspect about it is how inexpensive it is @ 550,000 CR
4. Koenigsegg Agera RS

Engine | 5.0L Twin-Turbocharged V8 |
Top Speed | 280 mph |
Horsepower | 1341 BHP |
Torque | 1010 LB-FT |
Weight | 3075 lbs |
Next on the list of the fastest car in Forza Horizon 4 is your buddy for exhilarating feats, soaring off-ramps, and exciting street races. To the dismay of some gamers, the Agera RS is a DLC car that must be acquired as part of the Car Pass add-on pack (or as part of the Deluxe or Ultimate Edition). It is, nevertheless, well worth your money, as it can go at a speed of 280 miles per hour. It also handles superbly and has excellent brakes, ideal for street racing and stunts.
5. Koenigsegg One: 1

Engine | 5.0L Twin-Turbocharged V8 |
Top Speed | 268 mph |
Horsepower | 1360 BHP |
Torque | 1011 LB-FT |
Weight | 2998 lbs |
This automobile has continuously been one of the fastest in the Forza franchise since its debut in its third game. Its flaw was replaced in Forza Horizon 4 by a slowed acceleration. Still, it isn’t easy to turn down a car that can stop and handle as well as this one while revving up to 268 mph. As one might imagine, the fifth fastest car in Forza Horizon 4 isn’t inexpensive, and at the Autoshow, it costs 2,850,000 CR.
6. Hennessey Venom GT

Engine | 6.2L Twin-Turbocharged V8 |
Top Speed | 270 mph |
Horsepower | 1200 BHP |
Torque | 1155 LB-FT |
Weight | 2685 lbs |
The Hennessey Venom GT’s handling and brakes are optimized for drag racing and straight-line driving. They’re decent, but they’re not designed for turning. It can reach the highest speed of 270 mph. In Forza Horizon 4, the Venom GT is similarly priced at 1,200,000 CR. You should probably stick to straightaways with this one because the handling and brakes aren’t quite up to par.

Top Speed | 267 mph |
Horsepower | 1479 BHP |
Torque | 1180 LB-FT |

Horsepower | 1183 BHP |
Torque | 1105 LB-FT |
Weight | 4044 lbs |

It accelerates quickly, from 0 to 60 mph in 2.4 seconds. It’s an excellent pick for drag races because of this. For 2,200,000 CR, you may get this at Autoshow.

Top Speed | 262 mph |
Horsepower | 946 BHP |
