With the SC780 package installed, output rises to 780 hp, while buyers can retain the six-speed manual transmission and receive an official warranty covering the upgraded equipment.
A Performance Sedan with a Supercharged V8
Even in standard form, the Cadillac CT5-V Blackwing stands apart from most modern cars in its class. Under the hood is a supercharged 6.2-liter V8 producing 668 hp and 659 lb-ft (893 Nm) of torque, with all power sent to the rear wheels.
Cadillac offers two transmission options: a six-speed manual or a ten-speed automatic. Among high-performance sedans, the combination of a large-displacement V8, rear-wheel drive, and a manual gearbox is becoming increasingly rare. Callaway has focused its attention on preserving that configuration.
New Supercharger and Cooling System
The SC780 package includes a 3.0-liter, twin-rotor GenFour supercharger that replaces the factory unit. It works with an upgraded TripleCooled intercooling system designed to maintain consistent intake-air temperatures, particularly under heavy loads and during sustained high-performance driving.
Following the upgrade, V8 output increases to 780 hp, while peak torque reaches 672 lb-ft (912 Nm). Callaway has not released revised acceleration or top-speed figures, although the additional output is expected to deliver noticeably stronger acceleration than the standard CT5-V Blackwing.
The package does not require replacing the factory transmission. Customers can still choose either the manual gearbox or the automatic. For a car at this performance level, that remains a significant distinction, as most manufacturers no longer offer manual transmissions in models with comparable power.
Exterior and Interior Changes
The exterior modifications are relatively restrained. The car receives a functional carbon-fiber hood intake along with a new carbon-fiber engine cover. In addition to changing the appearance of the front end and engine bay, these components are connected to improvements in airflow to the powertrain.
Inside, the package adds branded floor mats, decorative door-sill plates, and a dedicated key fob. The primary focus remains on mechanical performance rather than a major cabin redesign, targeting customers who want a more powerful version of the production sedan without fundamentally altering the vehicle.
A Warranty-Backed Upgrade
Callaway is known for its work on American performance cars, particularly the Chevrolet Corvette. Founded in 1977, the company initially developed turbocharging systems for European vehicles. Its engineering later attracted the attention of General Motors, and the firm subsequently worked with several major automakers.
The SC780 package for the Cadillac CT5-V Blackwing is offered through the brand's dealer network as approved optional equipment. The system is covered by a three-year warranty. This approach distinguishes the package from conventional aftermarket tuning, which can often affect a vehicle's factory warranty coverage.
The Cadillac CT5-V Blackwing with the Callaway SC780 package remains a rare example of a modern high-performance sedan combining a supercharged V8, rear-wheel drive, and a manual transmission. The upgrade raises output to nearly 800 hp while preserving the car's fundamental design and warranty support.
