The upcoming 2022 Cadillac CT5-V Blackwing ultra-high-performance luxury sedan will be the most powerful Cadillac ever, and its supercharged 6.2L V8 LT4 engine will also be in its most powerful form yet.
In the CT5-V Blackwing, the LT4 makes 668 horsepower and 659 pound-feet of torque. That puts it 18 horsepower and nine pound-feet of torque ahead of the version used in the 2015-2019 Chevy Corvette Z06 and the 2017-present Chevy Camaro ZL1, as well as 28 horsepower and 29 pound-feet of torque ahead of what was superficially the same unit in the 2016 Cadillac CTS-V.

In a recent interview with GM Authority executive editor Alex Luft, Mirza Grebovic, Cadillac Performance Variant Manager, explained why the LT4 in the CT5-V Blackwing has such an advantage over the CTS-V.
“The main differences (from CTS-V) were outside the internals: the exhaust and the induction allowed us to get more horsepower,” he said.
However, Grebovic also mentioned that Cadillac learned one important lesson from Chevy‘s treatment of the same engine.
“We did change the supercharger lid to give it a larger gap to the [inter]cooler to get more air in and better cooling performance. This was learning from the [Corvette C7] Z06 and the Camaro [ZL1]. So it does have a taller supercharger lid,” he concluded.
This is important because cool air is more dense than hot air. In other words, there is more oxygen for a given volume of air, which leads to stronger combustion and therefore more power. Without the taller supercharger lid, the power output of the LT4 in the CT5-V Blackwing might therefore have been much closer to that of the Chevy muscle cars.
The Cadillac CT5-V Blackwing and the 2022 Cadillac CT4-V Blackwing are scheduled to go into production at the GM Lansing Grand River plant in Michigan on July 5th, nearly a month before the regular (non-Blackwing) 2022 Cadillac CT4 and 2022 Cadillac CT5 luxury sedans. However, this depends partly on the ongoing semiconductor supply shortage which is affecting auto factories around the world.
The CT5-V Blackwing will be priced to start at $84,990, but it will be possible to spend $121,895 by specifying all the available options. These include GM’s 10-speed automatic transmission (replacing the standard Tremec-supplied six-speed manual), a carbon fiber aero package, and a Brembo ceramic brake package, among other options.
Even the higher figure is dwarfed by the $265,000 paid for the rights to own CT5-V Blackwing VIN 001 at the Barrett-Jackson Scottsdale auction in March. The entire sum is being donated to Black Ambition, which funds companies led by Black and Latinx entrepreneurs.
