The aluminum cylinder block features pressed-in iron liners, cross-bolted main bearing caps and houses a lightweight forged steel crankshaft, forged steel connecting rods and high strength hypereutectic aluminum pistons.
The intercooled turbochargers are mounted between the cylinder banks in a so-called hot-V configuration and their twin scroll design broadens their performance capability, offering quicker response and greater efficiency.
These produce up to 20 psi (1.4 bar) and are matched with electronic wastegate control for more precise boost management and more responsive torque production.
[citation needed] In spite of its power and sophistication, high cost to produce the engine and low demand for the CT6-V led to its cancellation in early 2020, before it could be expanded to Cadillac's Escalade line.
[2] Cadillac did not anticipate the strong demand and introduced the second CT6 model with detuned Blackwing engine: CT6 4.2 Platinum, which sold out quickly as well.
