Koenigsegg Agera R Compact Supercar

More power and less weight over the original Agera means the maths is simple: the Agera R reaches 200km/h (124mph) half a second faster. It also runs on biofuel.

As if the original 2011 Koenigsegg Agera wasn’t quick enough, the new 2013 Agera R has upped the ante, producing 850 kilowatts (1,140 horsepower) from the same 5.0-litre, twin-turbocharged V8 powertrain. Key differences come in that hallowed power-to-weight ratio: while the power in the Agera R has gone up, the bulk over the original has come down, thanks to some clever weight-saving measures.

Take in the new 48.3-centimetre (19-inch) wheels; not only are they made from carbon fibre (what else!), but they’re hollow-spoked too, providing a net save of 40 per cent over similar alloy wheels.

While other hypercars manage downforce via an active rear wing that changes height according to speed, the Agera R changes its angle of wing to literally target downforce upon the rear.

Further, the angle is not determined by heavy hydraulics, but by the pressure of the wind itself. With the angle of the wing dictated by wind resistance, this compensates for headwind or tailwind at the same given speed.

Likewise, the new Aero Exhaust is shaped to improve underbody air release, ensuring this latest Koenigsegg of continued aerodynamic evolution and greater speed.
