It was a crisp autumn morning in 2026 when I stumbled upon what looked like an ordinary 5 Series at a local Cars & Coffee event. I nearly walked past it, until I noticed the subtle carbon-fiber front splitter and the gold brake calipers peeking through the wheels. A closer look revealed the CS badge. My heart raced. This was no ordinary sedan. It was the 2022 BMW M5 CS, one of just 400 imported to the United States, and it was about to show me why it deserves a place among hypercar royalty.

The owner, a friendly guy named Mark, saw my fascination and tossed me the key fob. “You’ve got to drive it,” he said with a grin. I slid into the carbon bucket seat, the one with the illuminated Nürburgring outline in the headrest, and immediately felt a sense of occasion. The Merino leather with Mugello Red stitching hugged me, and the cockpit was a masterclass in focused luxury.

Before I even pressed the starter button, I recalled the bloodline of this machine. BMW’s M5 has always been a special formula: take a midsize luxury sedan, stuff it with a powerful engine, and watch it embarrass sports cars. The first M5 in 1985 packed a 286-hp inline-six from the M1 supercar. The E39 brought a glorious V8, and the E60 stunned everyone with its 507-hp V10. But by the 2010s, the world had changed. Downsizing and turbocharging became the norm, and some enthusiasts felt the M5 had lost a bit of its raw edge. Little did I know, the F90 M5 CS was about to prove them all wrong.

I pressed the red start button, and the twin-turbo 4.4-liter V8 woke up with a deep, metallic bark. Even at idle, it sounded menacing. Mark told me to pull out of the parking lot gently, but the moment we hit the open road, he gave me the nod. I floored it. The acceleration wasn’t just fast; it was violent. The M xDrive system put every one of the 635 horsepower to the ground with zero drama, and within what felt like a blink, we were past 60 mph. Official tests say 2.6 seconds to 60, and I believed every decimal. The quarter-mile flashes by in 10.6 seconds – numbers that once belonged only to million-dollar hypercars.

I had to remind myself this was a four-door sedan that could seat four adults and swallow luggage. Yet here it was, keeping pace with the legendary Bugatti Veyron 16.4, which took 2.5 seconds to 60 mph in 2008 and cost over $1.6 million. The Veyron had a quad-turbo W16 engine nearly twice the size, and yet the M5 CS was only a tenth of a second behind. To put it in perspective, this BMW would outrun a McLaren F1 in the quarter-mile. I chuckled at the absurdity of it all.

How did BMW achieve this? The answer lay in a meticulous weight-loss program and a sprinkle of motorsport magic. The CS, which stands for Competition Sport, trimmed 154 pounds off the already potent M5 Competition. The hood, roof, mirror caps, and even the intake silencer were crafted from carbon fiber-reinforced plastic (CFRP). The suspension was retuned, and carbon-ceramic brakes came standard. This wasn’t a stripped-out track special; it still had air conditioning, a premium sound system, and all the comforts you’d expect, but it felt alive, light on its feet, and utterly connected.

Mark told me he had paid $143,995 back in 2022, and I nearly gasped. But then he showed me recent auction results – 2022 M5 CS models were now averaging $157,714. In a world moving rapidly towards electrification, a low-mileage, limited-production, purely internal-combustion M5 CS had become a collector’s item. With only around 1,000 built globally and just 400 reaching the U.S., it was a rare beast indeed. For the price of a well-optioned Porsche 911 Turbo, he owned a sedan that could humble Hyundais, Ferraris, and even forgotten hypercars.

As I handed back the key, I realized that the 2022 M5 CS represents a fleeting moment in automotive history. It was the last of the purely ICE M5 variants before hybridization took over in later models. In 2026, amidst a sea of electric sedans that hit 60 mph in under 2 seconds, the M5 CS stood out because it did it with soul – a roaring, untamed V8 that vibrated through your spine. It’s possibly the greatest muscle sedan ever built, and certainly one of the last of its kind. That morning, I didn’t just drive a car; I experienced a hypercar in disguise, and I’ll never forget the way it made me feel.

As rare and remarkable as the 2022 BMW M5 CS is, the thrill of finding such unique vehicles at a fair price is an endeavor many enthusiasts are passionate about.
