Cadillac has no intention of abandoning the high-performance sedan segment. In addition to the new Cadillac CT5-V sports sedan, the CT5-V Blackwing will soon join the lineup. The difference? The Blackwing is expected to be powered by the discontinued CTS-V's supercharged 6.2-liter V8 with a total of around 670 horsepower and 630 lb-ft of torque. The CT5-V, meanwhile, has a 3.0-liter twin-turbo V6 rated at 360 hp and 405 lb-ft. In addition to coming with way more power, the Blackwing will boast some exclusive features. Cadillac already teased the muscle sedan's leather-wrapped steering wheel, complete with a 12 o'clock red racing stripe and carbon fiber trim.

Today comes a new revelation: carbon fiber racing seats. Cadillac has unveiled a new teaser shot confirming the CT5-V Blackwing will offer "premium racing-inspired seats" with a carbon fiber seat back, a precision book-matched design, and a laser-etched V-Series logo.

Additional "customer-centric innovations and features" will be announced at a later date, which should happen relatively soon because the Cadillac CT5-V Blackwing is slated to go on sale next summer. Pricing remains unknown at this time, but the CTS-V carried a starting price tag of nearly $90,000, just to give you an idea of what to expect. Also, Cadillac specifically points out the new CT5-V will be limited production, though chances are it'll stick around for more than one model year.

Other things we've learned so far about this potential BMW M5 killer is that it'll come standard with a six-speed manual transmission with an optional fast-shifting 10-speed automatic.

Styling-wise, there'll be a number of exterior modifications such as wider wheels, stickier tires, and bigger brakes. Cadillac's engineering team is also re-tuning the suspension for a far more aggressive driving experience, especially on the track.

Alongside the CT5-V Blackwing will be its smaller, less expensive, but still potent sibling, the CT4-V Blackwing. Reports claim it'll be powered by the also discontinued ATS-V's twin-turbo 3.6-liter V6, good for around 464 hp and 445 lb-ft. It too will share those transmission options. Expect the CT4-V Blackwing to be revealed alongside the CT5-V Blackwing and go on sale at around the same time. Whether it'll offer these insanely cool carbon fiber seats remains unknown.
