The car was exclusively built in only 230 units and there are some really interesting facts here. Each of the 959s cost more than $500,000USD to build, but was actually sold for far less than the half of this amount: $225,000 USD.

In addition, the 959 produced 450 horsepower (331 kW), which was a record at that time. The horses were generated by a sequential twin-turbo engine. 959's even won its class in the Paris-Dakar Rally.

918 Spyder is considered a hypercar. The reason for this is its power estimated at more than 900 horses (662 kW). What's interesting here is that it comes from the 4.6-liter naturally-aspirated flat crank V8 and its hybrid electrical system.

In addition, the car has been built almost entirely from carbon fiber. The 918 already set a production car lap record at Mazda Raceway Laguna Seca. What is more, it shattered the production car record at the Nürburgring by 14 seconds. All in all, it is a representation of world' newest highest performing vehicles.
