The 2026 Cadillac CT5-V Blackwing is set to receive an ultra-exclusive new option called the Deep Ocean package, and it doesn’t come cheap. According to a post on the Cadillac V-Net forum, the package costs $26,995 and will be limited to just 200 cars, instantly making it one of the rarest versions of Cadillac’s super-sedan.
The Cadillac CT5-V Blackwing already sits at the top of the performance sedan pile, pairing a 668-hp supercharged V-8 with an available six-speed manual at a starting price of $102,795. That figure undercuts rivals like the Audi RS7 and BMW M5 by tens of thousands, but options can quickly push the price north.
The Deep Ocean package is the most dramatic example yet, bundling both Carbon Fiber 1 and Carbon Fiber 2 packages along with the premium leather interior, which together account for $22,470 of the total cost.
What makes the package stand out visually is the new Deep Ocean Tintcoat paint, first seen on the Cadillac Optiq-V. It’s complemented by black exterior accents, blue brake calipers, and Santorini Blue seatbelts, giving the Blackwing a more bespoke, motorsport-inspired edge without altering its mechanical formula.
Cadillac hasn’t officially confirmed the package, but the forum images and details appear legitimate. Production is reportedly scheduled to begin next month at the Lansing Grand River plant in Michigan, with just 200 examples planned. If accurate, the Deep Ocean CT5-V Blackwing will become one of the most collectible modern Cadillacs—and one of the most distinctive takes on today’s ultimate American performance sedan.
