The 2022 Cadillac CT5-V Blackwing is the most powerful production car ever from General Motors’ luxury brand. Jason Fenske, host of the “Engineering Explained”, has all the details about the sample engine of the new performance sedan.
Blackwing is the name of both an engine and the highest level of Cadillac’s performance models. But the CT5-V Blackwing does not use the Blackwing engine, which was a 4.2-liter twin-turbo V-8 that started in the discontinued CT6-V sedan. Instead, Cadillac chose the 6-liter V-8 of the propelled car from the predecessor of the CT5-V Blackwing, the CTS-V. However, the engine is now set at 668 horsepower and 659-pound torque, compared to the previous 640 hp and 630 lb-feet.
The 6.2-liter propulsion V-8, in turn, is based on the LT4 engine that started in the C7-generation Chevrolet Corvette Z06 for the 2015 model. It is also a push rod engine, while the 4.2-liter twin-turbo V-8 boasts dual cams. The turbos are also located between the cylinder walls in a ‘Hot-V’ arrangement for better response.

In the CT6-V, the 4.2-liter engine produced 550 hp and a torque of 640 lb-ft, which is actually more hp per liter than the larger propulsion engine. In the CT6 sedan with four-wheel drive, the Blackwing engine achieved even better fuel consumption than the LT4 engine in the C7 Z06, Fenske noted. Why then does GM opt for the Chevy-derived engine over the Cadillac-specific car?
First, the rechargeable engine can spin higher than the twin-turbo engine – 6,600 rpm versus 6,000 rpm. The 6.2-liter engine is also fairly compact for its displacement, Fenske said (remember it was designed to fit under the low hood of a Corvette). It is also more responsive, he noted. Even if you do not agree with the choice of engine, it is also noteworthy that the CT5-V gets a standard six-speed manual gearbox – something that was not available in the CT6-V or CTS-V sedan.
The CT5-V Blackwing could also be one of the last of its breed. Just before the unveiling of the propulsion sedan, GM announced that it was ‘striving’ to eliminate the exhaust pipes of all its passenger vehicles and light trucks by 2035. Although the aspiration is different from the commitment, it is a sign that the days of the internal fires in America have been numbered. largest car manufacturer. Even before the announcement, Cadillac was expected to become mostly electric within the next decade, starting with the Lyriq SUV and Celestiq sedan.
