Hmm... spec wise it is somewhat close (502 bhp, 1.6L, 4 cylinders), and also there sort of another connection too:

Developed by Cosworth initially as a Formula 1 engine (before the FIA changed its mind and ditched 4-cylinder units for V6 engines for the 2014 season), the powerplant then found its way on to the Jaguar C-X75 prototype.

Also: for comparison Renault and Mercedes have released these of their next year's F1 engines:

Renault engine peaks at around 10500 rpm and changes gears at 12000 rpm (mentioned in another source).
