The Cadillac Blackwing V8 (GM RPO LTA) is a twin-turbo DOHC V8 engine that was produced by the Cadillac Division of General Motors for use in its CT6-V between 2018 and early 2020. It is a clean sheet engine design, as well as the Division's first ever twin-turbo V8 engine. The engine was branded as the "Blackwing V8" by GM technicians, and is the first Cadillac-exclusive dual overhead cam V8 engine since the Northstar V8 was dropped in 2011. All versions were to come equipped with the Ford 10L90 10-speed automatic transmission and Cadillac's all-wheel drive system.
