Dutch automaker Spyker unveiled this luxury crossover SUV at the 2006 Geneva Auto Show. Named in honor of the 1907 Peking-to-Paris car rally, the vehicle was hugely popular immediately after its debut. But Spyker was in the midst of financial troubles and never got the vehicle into production. As recently as April 2017, rumors of a revival have resurfaced.
