The Agera R is to the Agera what the CCXR is to the CCX. If that statement means nothing to you, then think of the Agera R as a more environmentally friendly and more powerful version of the base Agera. Using the beneficial qualities of E85 biofuel, including a higher octane rating and cooling abilities, the engine can run with higher compression, boost pressure, and more spark advance compared to the normal engine.
The result is a Veryon Super Sport-comparable 1,100 hp on E85 biofuel and peak torque of 885 lb-ft. of torque from its in-house 5.0-liter twin-turbocharged V-8 engine. But wait, doesn’t the CCX and the Agera use a 4.7-liter V-8? Well, Koenigsegg has also taken this time to announce the new 5.0-liter V-8 that the company will be utilizing in the base Agera and Agera R.
Koenigsegg says that the Agera R utilizes a particularly robust engine capable of withstanding extreme pressures. Utilizing a purely theoretical tool called Brake Mean Effective Pressure (BMEP), Koenigsegg says the Agera has a BMEP rating of 406 psi on 95 octane and 435 psi on E85 biofuel. The best production engines from other leading manufacturers have a maximum BMEP of around 319 psi. The Agera’s turbochargers have a maximum pressure of 22 psi.
A newly developed seven-speed gearbox for the Agera features dual clutches for very smooth, yet extremely fast shifts. The Agera also makes use of what Koenigsegg calls one of the lightest and fastest E-Differentials on the market. The E-Diff takes into account the throttle angle, g-forces on the car, steering wheel angle, yaw angle, car speed, engine rpm, selected gear, and weather conditions. It also works in harmony with the new traction control system that Koenigsegg says is the fastest reacting in the industry.
The aerodynamics of the Agera are top notch. Even with the massive rear wing in place, the coefficient of drag is 0.33 in high-speed mode and 0.37 in track mode. The dynamic rear wing will alter its position not only because of the car’s speed, but also depending on pressure of the wind. It can thus compensate for headwind or tailwind at the same given speed. Koenigsegg says the Agera R has a “theoretical” top speed of around 273 mph, given the car’s gear ratios, aerodynamics, and power. All Agera models are limited to 230 mph in standard mode, but the governor can be unlocked if all necessary conditions are met (tire wear, service level of car, etc) in the infotainment system.
A large 21-gallon fuel tank is centrally located into the carbon fiber monocoque chassis to help the Agera pass the U.S. high-speed rear impact test. So, yes, the Agera, unlike the CCX, will be marketed and sold inside the United States without any special alterations or show car licenses. Another benefit of the fuel tank’s position is that the weight distribution of the Agera does not change if the tank is full or close to empty.
Koenigsegg has paid particular attention to the Agera’s luggage space to allow the owner to hold his or her luggage or for the easy stowage of the one-piece roof/hardtop. Like the Acura NSX and unlike the umbrella in the Veyron Grand Sport, the Agera will easily convert from open-top roadster to closed coupe mid-trip while still being able to handle a set of golf clubs.
The particular Agera R pictured—production car number 83—has been tailored for a specific customer. It includes a Speed Racer theme for the exterior and a custom-made roof box. Its custom Michelin tires, according to Koenigsegg, achieve lateral accelerations up to 1.6 g in dry conditions and are rated for speeds over 260 mph, making them the highest top-speed rated tire in the world.
