Agera Top Speed and Record Performance
The Koenigsegg Agera RS set the production car top speed record at 277.9 mph (447.2 km/h) during a closed public road test in Nevada in November 2017, as confirmed by independent timing equipment and reported by automotive journalists and Koenigsegg itself Forbes. The run used two directional passes on a long straight section of Nevada State Route 160, with the average of both directions used to calculate the final top speed figure Koenigsegg. This record made the Agera RS the fastest production car in the world at the time, surpassing previous benchmarks held by other hypercars.
The Agera RS top speed was achieved using a twin turbo V8 engine producing 1,341 hp on standard gasoline and 1,360 hp on E85 biofuel, paired with a lightweight carbon fiber body and active aerodynamics that generate significant downforce at extreme velocities Koenigsegg. The car uses a 7-speed dual clutch transmission, rear-wheel drive, and a specially calibrated suspension and braking system designed to handle sustained high speed runs while maintaining stability and driver control Forbes. These engineering choices allow the Agera to reach its top speed within a short distance and then decelerate safely using carbon ceramic brakes and aerodynamic drag.
Agera RS Technical Specifications and Engine Details
The Agera RS is powered by a 5.0 liter twin turbo V8 engine that delivers 1,341 hp on pump gasoline and up to 1,360 hp when running on E85 ethanol blend fuel, making it one of the most powerful production car engines ever built Koenigsegg. The engine uses a direct injection system, variable valve timing, and a unique pneumatic valve actuation system to achieve high rpm and efficient combustion at extreme power levels.
The Agera RS chassis is built entirely from carbon fiber, including the monocoque, body panels, and crash structures, resulting in a curb weight of approximately 3,100 pounds (1,410 kg) Koenigsegg. The car features active aerodynamics with adjustable front and rear wings, a deployable rear diffuser, and underbody venturi channels that generate over 1,100 pounds of downforce at top speed, keeping the car planted on the road surface.
Comparison With Other Fast Production Cars
The Agera RS top speed of 277.9 mph places it among the fastest production cars ever tested, though other manufacturers have since claimed higher speeds using different testing methods or specialized configurations
