Cadillac Gives CT4-V Blackwing Extreme Carbon Aero Package

Sports Cars / 1 Comment

It has more downforce than any V-Series that came before.

The Cadillac CT4-V Blackwing will be the company's most enthusiast-friendly vehicle. It rides on the second generation of GM's Alpha platform, which also underpins the back-in-production Chevy Camaro, it uses a twin-turbo V6 making 472 horsepower and 445 lb-ft of torque and comes standard with a six-speed manual directing power to the rear axle, making it unique among peers like the Mercedes-AMG CLA 45. Now, Caddy is adding carbon fiber aero to crown it as the vehicle with the highest downforce in V-Series history.

"Aero performance was key to helping deliver the uniquely agile, engaging driving experience in the CT4-V Blackwing," said Scott Sier, aerodynamics performance engineer for Cadillac. "Thanks to components like the underwing, we were able to work with design to generate downforce without the use of large wings that didn't fit with the design."

The packages were developed at the company's rolling-road wind tunnel in Warren, Michigan, where you can do more work than with a no-road wind tunnel. Cadillac says that engineers can spend more time fine-tuning the components and that "the five belts provide a more accurate simulation of under-vehicle airflow than previous-generation wind tunnels."

The aero package, which will be available for both the CT4-V Blackwing and the more expensive CT5-V Blackwing, comes with a front underwing inspired by Cadillac's DPi race car that helps press the car into the road, as well as cooling other components. The pack also adds front dive planes, an "extra-aero" rear spoiler, the V-Series mesh grille, brake cooling ducts, fender vents, a new front splitter, rocker extensions a rear diffuser, a flat underbody, and rear control arm covers, which prevent air from building up around the rear wheel well.

There will be two packages, the first of which includes the dive planes, underwing strakes, splitter, spoiler, and front-wheel deflectors for $4,350. The second package includes the rocker extensions and rear diffuser for $2,650.

"We set out to create a capable and balanced performance sedan not just with mechanical grip, but aerodynamically as well," said Tony Roma, chief engineer, Cadillac V-Series Blackwing. "With the CT4-V Blackwing, we create net downforce that is incredibly rare in production vehicles. What this means is that the car gets pressed down into the road the faster you go, giving it more grip, greater stability and inspiring the driver to confidently explore its full capabilities."

Strangely, Cadillac doesn't make any claims as to how much downforce all this aero adds, but with more than 500 hours of wind tunnel testing and 300 simulations going into the development, you can bet that each and every dive plane, duct, and aero flic will enhance grip at high speed out on track.

Cadillac says that its initial reservations for the Blackwings sold out quickly, but there are some still available for order. The CT4-V Blackwing starts at $59,990 and vehicles will arrive at dealerships in late summer.
