2025 Supersedans Faceoff: Cadillac CT5-V Blackwing vs Audi RS7 vs BMW M5

In 1966, Bob Dylan's electrified performance at Manchester's trade hall changed music forever. In a similar vein, the 2025 Cadillac CT5-V Blackwing is a bold statement in the world of supersedans. It’s all about delivering raw power with an old-school flair. Let’s dive into what makes the CT5-V, Audi RS7 Performance, and BMW M5 the top contenders in the high-performance sports car arena.

Interior and Exterior

When it comes to size, the BMW M5 is a giant. At nearly five inches longer than the Cadillac and three inches taller than the Audi RS7, it’s clearly built to dominate the road. But with size comes weight—the M5 tips the scales at 5251 pounds. The Audi is more nimble at 4830 pounds, while the Cadillac keeps it sleek at 4127 pounds.

Each car's exterior is a blend of design and function. The M5’s aggressive front fascia contrasts with the more refined looks of the Audi RS7 and Cadillac CT5-V Blackwing, which keeps things classy with carbon fiber accents that really stand out.

Luxury Car Interior Features

Inside, each supersedan offers a unique experience. The Cadillac CT5-V integrates a minimalist array of displays atop its dashboard, while the Audi RS7 boasts a more open, airy cabin with a panoramic sunroof. However, while the RS7 offers practicality with its rear hatch, the Cadillac's rear seat is noticeably more basic, reflecting its lower starting price.

Advanced Driver-Assistance Systems (ADAS)

All three vehicles are packed with tech, from the BMW's semi-autonomous driving capabilities to the Cadillac's adaptive cruise control and the Audi's cutting-edge lane-keeping assist. These systems, together with their turbocharged engines, provide a driving experience that’s as safe as it is thrilling.

Powertrain and Performance

Each of these supersedans offers a unique powertrain. The Cadillac's 6.2-liter supercharged V8 pumps out 668 horsepower, paired with a 10-speed automatic transmission, delivering pure rear-wheel-drive power. The Audi's 4.0-liter twin-turbo V8 produces 621 horsepower, while the BMW’s 4.4-liter twin-turbo V8 combined with an electric motor hits a blistering 717 horsepower.

Turbocharged Engine Performance

The M5's plug-in hybrid powertrain pushes the boundaries of performance, but the extra weight makes it a bit sluggish in certain situations. On the other hand, the Cadillac’s V8 is responsive, showing a 0-60 mph time of 3.7 seconds, closely followed by the RS7 at 2.9 seconds, thanks to its all-wheel-drive system.

Aerodynamic Car Design

Handling is where these cars truly differentiate themselves. The Cadillac CT5-V Blackwing shines on the skidpad, clocking in at 1.09 g’s, while the Audi RS7 impresses with its grip and effortless cornering. The BMW M5, despite its weight, handles corners with agility that defies its size, showcasing the evolution of high-performance sedans.

Driving Experience

Get behind the wheel, and the Cadillac delivers an exhilarating, raw driving experience, perfect for those who love engaging with a car’s full potential. The BMW, with its hybrid tech, brings an entirely different flavor, offering instant torque but requiring a learning curve with its massive frame. Meanwhile, the Audi RS7 provides a smooth, almost effortless driving experience, making it a great all-rounder.

Next-Gen Infotainment Systems

Infotainment is another area where these cars show their technological prowess. The Cadillac’s interface is sleek but relatively simple, with all the essential features at your fingertips. The Audi RS7’s system is the most user-friendly, offering intuitive controls and seamless connectivity. The BMW M5, however, has a complicated system that may overwhelm tech enthusiasts.

And the Winner Is...

After several days of testing in the mountains of Ojai, California, the Cadillac CT5-V Blackwing emerged as the victor. Despite the BMW's futuristic hybrid tech and the Audi’s precision handling, the Cadillac’s classic rear-drive dynamics and aggressive V8 won us over. It’s a timeless performance sedan that balances raw power with a nod to the past.
