Here are two snapshots of the McLaren 650S. McLaren said the 650S would slot between the P1 hypercar and the 12C.

Not much is known about the 650S, but as the name refers, the output is 650PS from the modified powertrain sourced from the regular 12C, which sports a 625PS (616bhp) 3.8-liter twin-turbocharged V8 connected to a 7sp dual-clutch transmission.
