7. Koenigsegg 5.0-liter Spyker V8
Swedish hypercar manufacturer Koenigsegg produces cars with unbelievable power levels and obsessive attention to detail. Also, they’re known for producing their own engines, which every knowledgeable car fan appreciates. Their latest creation is a 5.0-liter V8 which they will produce in naturally aspirated, as well as turbocharged versions. The N/A variant will deliver 600 HP and will go to the new Spyker model.

The version with forced induction will power the new Koenigsegg supercar. The same engine when turbocharged delivers 1,350 HP in the Koenigsegg One:1 model. The factory even claims that this powerplant could produce as much as 1,500 HP with special fuel as an added boost. An interesting thing about Koenigsegg engine production is that the company experiments with engine heads without the camshafts. It will be interesting to see future V8s they equip with this system.
