Power for the Cadillac CT6 V-Sport:

255 cubic inches, DOHC, 550 HP / 627 LB-FT (90% torque available at 2,000 RPM), up to 20# boost. Extremely compact.

Speculation it may possibly be used in mid-engine Corvette, based on extremely compact size.

Those coolant utilizing heat exchangers for one........
