The Agera R has a larger 5.0-liter twin-turbo V8 producing an earth moving 1115 PS (1099 bhp / 820 kW) and 1200 Nm (885 lb-ft) of torque.

Ferrari, Pagani and Lamborghini won't be the only supercar manufacturers soaking up the Geneva spotlight. In less than two days journalists will also be flocking to the Koenigsegg stand to check out the Agera R.

It was just a year ago when Koenigsegg debuted the Agera in Geneva packing a twin-turbo 4.7-liter V8 with 910 PS (669 kW / 898 hp) and 1100 Nm (811 lb-ft) of torque. With performance specs such as 0-100 km/h in 3.1 seconds, top speed of 390+ km/h (245+ mph) it certainly lands itself firmly in the hypercar category.

However, this Agera R is "slightly" improved. It has a larger 5.0-liter twin-turbo V8 producing an earth moving 1115 PS (1099 bhp / 820 kW) and 1200 Nm (885 lb-ft) of torque. A pretty astonishing figure but one crucial detail in achieving that number is the fuel. Fill it up with 95-octane fuel and the engine's potential is limited to 940 PS (927 bhp / 691 kW) and 1100 Nm (811 lb-ft) torque while full potential is only unleashed with the use of E85 biofuel.

No performance specs have been released yet for the Speed Racer themed hypercar but Koenigsegg is keen to mention the Agera R is equipped with Vortex Generating Rim (VGR) wheels. The design of the spokes generate a turbine effect which help in creating some downforce. Special Michelin tires were developed specifically for the Agera R and hold a speed rating of up to 260 mph (419 km/h), the highest-speed-rated tires in the world, according to Koenigsegg.

As a special request of the Agera R's owner, Koenigsegg in cooperation with Swedish roof rack manufacturer, Thule, created a custom carbon fiber roof box which is permanently attached as a single-piece to the roof panel. When the roof box is removed, the standard roof panel is pulled out of the trunk and put into place.
