Thanks to the car spotter Ron Alder W Photography, we can now share with you, the first pictures of the new Koenigsegg Agera S, which were taken in Hong Kong. 
There are no official details at the moment, but from the pictures we can only assume that those are one-piece carbon fiber wheels and winglets that were added to the second generation Agera R.
We know that Koenigsegg developed the Agera S for countries where Biofuel is not readily available.
This means that owners of this supercar can still enjoy the all of its 1,030 horsepower capabilities by using premium fuel instead of the Agera R’s Flex biofuel capabilities. Also, when running on premium fuel, the Agera S produces 1030 hp (768 kW) and 811 lb-ft (1100 Nm
