BMW M5 CS 2021 Complete Review: Performance, Handling, Value

The BMW M5 CS from 2021 represents the zenith of performance sedan engineering, fusing explosive power with everyday usability. This limited-edition model refines the M5 Competition formula, shedding weight and boosting output to claim the throne among fast executive cars. Despite its substantial size and cost, it delivers an intoxicating drive that few rivals can match.

Engineering Excellence Under the Hood

At the heart of the M5 CS lies a 4.4-liter twin-turbo V8 engine producing 626 horsepower and 553 lb-ft of torque, a 10bhp uplift over the M5 Competition. This powerplant propels the car from 0-60mph in under three seconds, with launch control providing explosive starts that pin occupants to their seats. Unique engine mounts reduce vibrations, ensuring the power delivery feels refined even at full throttle.

Beneath the carbon-fiber bonnet emblazoned with the CS logo, BMW engineers focused on marginal gains. The automatic eight-speed transmission shifts crisply, though some enthusiasts note a dual-clutch setup could sharpen responses further. All-wheel drive with dynamic rear bias allows 2WD mode for purists, but full xDrive grip maximizes track pace, shaving seconds off lap times.

Chassis Dynamics and Weight Reduction

BMW trimmed 70kg from the M5 Competition, bringing curb weight to around 1,825kg—still hefty, but lighter than its G90 successor by 600kg. Carbon-ceramic brakes enhance stopping power, resisting fade during aggressive sessions. Revised suspension geometry, stiffer dampers, and Michelin Pilot Sport Cup 2 tires create a setup that balances compliance on roads with razor-sharp cornering.

Drivers report the front end dives eagerly into turns with minimal steering input, while the rear tracks precisely, thanks to the long wheelbase and responsive helm. In Race mode, the ride feels connected yet composed over bumps and cambers, outperforming the standard Competition. Limits are high, demanding committed inputs to unsettle, and when pushed, the car remains progressive and transparent.

Luxury Meets Ferocity Inside

The cabin retains the 5 Series’ upscale ethos, amplified with M-specific touches like Alcantara-trimmed seats, carbon-fiber accents, and customizable ambient lighting. Heated seats and a power-adjustable wheel add comfort for daily duties. Rear space omits the middle seat for weight savings, prioritizing two passengers’ luxury over five-seat versatility.

Technology shines with a head-up display for performance data and intuitive infotainment. Despite the car’s track focus, it remains a plush cruiser, isolating road noise effectively.

On-Road and Track Performance

Real-world testing reveals the M5 CS as a point-and-shoot missile on highways, with effortless overtaking and serene high-speed stability. On twisty roads, it flows rhythmically, encouraging rhythmical inputs without drama. Track sessions highlight its poise; even with passengers, it laps quicker than expected, aided by xDrive and massive grip.

• Highway cruising: Quiet and stable at triple-digit speeds.
• Cornering: Precise steering and balanced chassis for confidence.
• Braking: Immense power with short distances.
• Daily usability: Comfortable ride in softer modes.

Critics praise its ability to handle mass through clever tuning, making it accessible yet thrilling.

Rivals in the Crosshairs

The M5 CS eclipses the Audi RS6 Avant and Mercedes-AMG E63 S in pure driver engagement. The RS6 offers wagon practicality but lacks the BMW’s chassis sparkle. The E63 S matches straight-line speed but feels less agile. At around $170,000 CAD, the CS commands a premium, justified by its superior dynamics.

Pricing, Availability, and Verdict

Launched as a 2021-2023 halo model, the M5 CS was a collector’s item, marking the end of V8 M5s before electrification. Its price reflected exclusivity, but resale values hold strong due to limited production. Minor gripes include the automatic’s occasional hesitation and high cost, but these pale against its prowess.

Ultimately, the M5 CS is the supersaloon gold standard—outrageous, indulgent, and unmatched.
