2. Cadillac Blackwing Twin-Turbo V8
Although the GM powertrain division is among the best in the world, most drivers were surprised to learn about Cadillac’s new Blackwing V8. This is a clean-sheet design and the first twin-turbo unit Cadillac has ever produced. It’s an all-aluminum engine with a modern cylinder head construction. The “Hot V” configuration means the turbochargers are between the cylinder banks.
The engine has a displacement of 4.2-liters and a nominal power output from 500 to 550 HP. This engine is available in only one model, the Cadillac CT6-V, starting from the 2019 model year. This is a limited-production model that magazine testers called one of the best American sedans ever built.
