Cadillac has launched a limited edition of its CT5-V Blackwing sedan, the F1 Collectors Series. The special version comes with an upgraded supercharger that boosts the engine's output to a whopping 685hp and torque to 913Nm.

The enhanced power makes this model the most powerful CT5-V Blackwing ever produced. However, only 26 units will be made, each of which will come with a six-speed manual transmission and Cadillac's Precision package as standard.
