Influential American Engines That Changed Cars Forever

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.

1. Ford 7.3-Liter Godzilla V8

You probably know about the Coyote 5.0-liter in the Mustang and the fantastic Voodoo 5.2-liter V8 in the Shelby GT350, but what’s the new 7.3-liter Godzilla? It’s one of the hottest new V8 engines designed especially for heavy-duty trucks and towing. The 7.3-liter is famous for its unique characteristics and distinctive old-school approach in a modern package.

The 7.3-liter Godzilla V8 is a push-rod, small-block, gasoline V8 engine that looks like it came from the ’60s. But with the latest technologies, state-of-the-art fuel injection systems, modern castings, and electronic engine management, it’s far from vintage. The new 7.3-liter is brutally-dependable, tough, and easy to repair. Surprisingly, it is also economical, powerful, and can last millions of miles. The nominal power figures are 430 HP and 475 lb-ft of torque, but the Blue Oval guys are sure to offer much more from this package.

These 20 influential American engines helped change the car world. Even nowadays, they’re still making an impact on how the major car manufacturers produce engines. While newer engines are coming, the older ones are still powering many cars on the roadways today.
