The Cadillac CT6 is one of our favorite cars here at Business Insider. Its combination of style, luxury, and technology certainly has us smitten.

As amazing as its 400 horsepower twin-turbo V6 may be, deep down inside, it just didn't feel quite right. A big Caddy should have a V8.

Well... it does now.

On Wednesday, Cadillac unveiled the new CT6 V-Sport complete with an all-new 4.2-liter, twin-turbocharged V8 that's expected to produce 550 horsepower.

"With the introduction of the all-new CT6 V-Sport, Cadillac begins a new chapter in its performance legacy with the introduction of the brand's first-ever twin-turbo V-8 engine," Cadillac president Johan de Nysschen said in a statement. "It is the centerpiece of the new CT6 V-Sport, an engaging sports sedan infused with DNA of Cadillac's world-renowned and championship-winning motorsports program."

The new turbochargers on Cadillac's new V8 sit in the valley between the two banks of cylinders in a "hot V" configuration. According to Cadillac, this layout virtually eliminates turbo lag and helps the engine fit into smaller spaces.

The new V8 will be paired with a 10-speed automatic transmission, a mechanical limited-slip rear differential, and V-Sport tuned suspension.

In addition, the CT6 V-Sport will feature Cadillac's trick Magnetic Ride Control adaptive suspension, massive 19-inch Brembo brakes, and a V-Sport active exhaust.

The V-Sport will arrive in showrooms as a 2019 model as part of Cadillac's planned refresh of the entire CT6 range.

Non-V-Sport CT6 models will receive updated front and rear fascias based on the Escala concept car.

Performance and pricing data are not yet available for the 2019 Cadillac CT6 V-Sport.
