There’s something undeniably addictive about the way the 2025 BMW M4 Competition Cabriolet puts power to pavement. It doesn’t just move fast—it feels alive under you, pulling hard through each gear with an urgency that never gets old. Laguna Green might turn heads, but it’s the way this car drives that stays with you. This isn’t just a convertible with big numbers. It’s an experience that demands your attention and rewards every input with precision.
Under the hood is BMW’s S58 engine, a 3.0-litre twin-turbocharged inline-six delivering 523 horsepower and 479 lb-ft of torque. Power is routed through an eight-speed M Steptronic automatic transmission to a rear-biased all-wheel drive system. Acceleration is sharp and forceful, with a 0–100 km/h time of just 3.7 seconds. The M4 Cabriolet finds grip with ease and feels stable under hard throttle, even in less-than-ideal conditions.
Despite its performance capabilities, the M4 is not difficult to live with. Ride quality is firm but refined, and the suspension does a good job of absorbing day-to-day imperfections without feeling disconnected. The steering feel is tight and confidence-inspiring. The added weight of the convertible top doesn’t take away from the car’s responsiveness. On the highway, it feels planted and composed. Through tighter corners, the chassis remains neutral, offering genuine balance even when pushed. That said, the suspension is tuned for performance, which means it can feel a bit harsh over rougher pavement. It’s not uncomfortable, but those expecting a plush ride may find it firmer than expected, especially in the sportier drive modes.
Drop the roof and the experience takes on another layer. Exhaust notes become more prominent, and Laguna Green starts to really glow in the light. When it’s time to seal things back up, the roof operation is quick and smooth. With the top raised, wind intrusion is minimal and cabin noise remains well controlled, making it feel like a proper coupe when fully enclosed.
Inside, the M4 blends premium materials with a driver-focused layout. The Ivory White Merino leather feels supple, and the M carbon trim adds just the right amount of contrast. The seats offer excellent bolstering and long-distance comfort, while the seating position stays low and sporty. Controls fall easily to hand, and the large paddle shifters invite frequent manual use.
BMW’s curved display combines a 12.3-inch digital cluster with a 14.9-inch touchscreen running iDrive 8.5. The system is responsive and features multiple customization options. Climate controls are integrated into the screen but remain accessible. Wireless Apple CarPlay and Android Auto are included, as is a premium Harman/Kardon sound system that performs well across all genres.
Our tester also included the Premium Package and Driving Assistant Professional, adding features like adaptive cruise control with stop-and-go, lane centering, a head-up display, and a full surround-view camera system. These additions help take the edge off daily commuting without compromising the M4’s performance roots.
Pricing for the 2025 BMW M4 Competition Cabriolet starts at $110,200. Our test car was optioned with the Premium Package, Advanced Driver Assistance Package, BMW Individual Laguna Green Metallic paint, Ivory White Full Merino Leather, ventilated seats, M Sport Brakes, and more, bringing the total to $128,050 before fees and taxes
Natural Resources Canada rates the M4 Competition Cabriolet at 13.7L/100km in the city, 9.3L/100km on the highway, and 11.7L/100km combined. We averaged 10.3L/100km during our week of mixed driving, which is impressively reasonable for a car with this much performance on tap.
The 2025 BMW M4 Competition Cabriolet stands out not just for its stats, but for how they come together in motion. It’s fast in a way that feels deliberate, not overwhelming. Power delivery is sharp, the shifts are snappy, and the exhaust crackles with just enough aggression to leave a smile every time you lift off. The ride may be firm, but that’s part of what keeps the experience focused. This isn’t a car that fades into the background—it invites you in and makes you want to keep driving. For those who value feedback, engagement, and a bit of theatre with their speed, the M4 Cabriolet delivers in full.
