Cadillac’s beast of an engine is back with the CT4-V and the CTV-5 Blackwing.

The CTV-5 will be powered by an upgraded 6.2L supercharged V8 that will produce an eye-watering 668 horsepower and 659 lb.-ft of torque. It will be mated to a standard 6-speed manual transmission, or an optional 10 speed automatic. 0-60mph times are estimated to be less than 3.7 seconds.

The CTV-4 will feature a 3.6L twin-turbo V6, producing 472 horsepower and 450 lb.-ft of torque. The estimated 0-60mph time is around 3.8 seconds. This model will also come standard with a 6-speed manual transmission or an optional 10-speed automatic transmission.

The Blackwing was originally designed to replace the Cadillac Northstar engine. It featured twin turbos in a V8 configuration and was made for the CT6. The original Blackwing engines were also hand-built and featured a signed nameplate and number on the engine.

The engine was cancelled early in 2020 due to limited sales and then the pandemic. However, with extreme renewed interest in Cadillac sedans with the CTV-4 and CTV-5, Cadillac decided to bring it back. This time, with two versions of the engine, and upping the ante with a supercharger and higher power output on the flagship V8.

We have no indication yet if we are getting any to retail. They will be coming in only RWD configuration, so a great summer driver.
