Here Are Final Cadillac Blackwing Engine Production Numbers: Video

The twin-turbocharged 4.2L V8 Cadillac Blackwing engine (production code LTA) was used exclusively in the Cadillac CT6 Platinum and CT6-V. With production of the high-performance engine now concluded for several years, Cadillac Society has obtained the final tally of how many of these unique eight-cylinder engines were produced, and we break it all down in the latest (and long-promised) episode of the Cadillac Society podcast.

All told, there were exactly 1,200 examples of the CT6 produced with the Cadillac Blackwing engine. 915 of these went into the CT6-V, while the remaining 285 went into the 4.2L Platinum model.

Cadillac Blackwing Engine Production Numbers
Model Year	2019	2020	Total
CT6-V	504	411	915
4.2L Platinum	168	117	285
Total Units With Blackwing LTA Engine	672	528	1,200
Total CT6 Units	6,783	3,816	10,599
CT6 Blackwing Engine Ratio	9.9%	13.8%	11.3%

In terms of model year, 672 units were 2019 models, representing nearly 10 percent of all 2019 CT6 models produced. Meanwhile, 528 examples were produced for the 2020 model year, making up 13.8 percent of all 2020 Cadillac CT6 production.

The 1,200 total is slightly lower than the luxury marque’s initial production plans. Back in 2020, Cadillac Society reported that Cadillac planned to produce 1,500 units of the CT6 with the Blackwing engine, but it seems that the marque ultimately fell short of that projection.

As a reminder, the Cadillac Blackwing engine was standard on the 2019 and 2020 model year CT6-V performance sedan and optional on the CT6 4.2L Platinum. It is rated at 550 horsepower and 640 pound-feet of torque in the Cadillac CT6-V, and 500 horsepower and 574 pound-feet of torque in the CT6 4.2L Platinum. The engine features a dual overhead camshaft (DOHC) configuration, a lightweight aluminum cylinder block, a forged steel crankshaft, forged steel connecting rods, and aluminum pistons, along with twin turbos in a hot-v configuration. The Blackwing engine was also the very first Cadillac V8 with a DOHC layout since the Northstar, making it that much more special.

It’s worth noting that the engine was available for purchase via Cadillac’s parts catalogs as a “replacement part” as late as 2022. In other words, it was for sale as a replacement for units of the CT6 that may have suffered premature engine failure and was not offered as a standalone crate engine for project cars. However, it has since been delisted from the options catalog.
