Cadillac Blackwing Engine
The Cadillac Blackwing engine is an internal combustion engine developed by General Motors for Cadillac luxury automobiles.
Current Engine
The current Blackwing engine is the 4.2 liter V8. Assigned GM RPO code LTA, the eight-cylinder, Dual-Overhead Cam (DOHC) gasoline engine is the result of a new clean-sheet design. It’s also Cadillac’s first-ever twin-turbo V-8 engine. The Blackwing first launched on the 2019 Cadillac CT6.
The Cadillac Blackwing engine (LTA) is a clean-sheet design that was developed with the goal of delivering exceptional power density. It also introduces various unique design elements developed to balance performance and efficiency with compact, mass-efficient packaging.
The Blackwing engine is highlighted by the following characteristics:
- Twin-scroll turbochargers
- Electronic wastegate control
- Twin water-to-air charge coolers
- Twin throttle bodies
- Direct injection
- Dual-independent camshaft phasing
- Active Fuel Management / Cylinder Deactivation
- Variable-pressure oiling system
- Stop/start technology
The Cadillac Blackwing engine is available in two versions:
- A regular-output version making 500 horsepower and 553 pound-feet of torque
- A high-output variant making 550 horsepower and 627 pound-feet of torque
Applications
The Cadillac Blackwing engine is currently used in the following vehicles.
| Model Year | Brand | Model | Engine | Transmission | Power hp / kW @ RPM | Torque lb-ft / Nm @ RPM |
|---|---|---|---|---|---|---|
| 2019 | Cadillac | CT6 Platinum | LTA | 10L90 | 500 / 373 @ 5000-5200 | 553 / 750 @ 2600 – 4600 |
| 2019 | Cadillac | CT6-V | LTA | 10L90 | 550 / 410 @ 5700 | 627 / 850 @ 3200 – 4000 |
We expect the Blackwing motor to also be used in the 2020 Cadillac Escalade as well as in the high-performance version of the Cadillac CT5, potentially called CT5-V.
Potential Engine Family
It is possible that the Cadillac Blackwing engine is not a single engine, but will be developed into an engine family of sorts – with various sizes (displacements, cylinder counts) and power output.
As of this writing, however, this rumor has not been confirmed by Cadillac, or otherwise substantiated.
