Introduction
The words “convertible” and “hardcore performance” don’t always go together — unless you’re talking about BMW’s latest M4.
The 2025 BMW M4 Competition xDrive Convertible takes everything we love about the hardtop coupe — speed, balance, brute force — and brings it to the open air. And it doesn’t just work. It thrives.
This luxury vehicle isn’t just a summer cruiser. It’s a true M car that happens to let the sun in when you want it.
Power That Doesn’t Quit
At the heart of the M4 Convertible is BMW’s trusted 3.0-litre twin-turbocharged inline-six engine. No changes needed — it still cranks out a healthy 523 horsepower and 479 lb-ft of torque.
All that muscle gets routed through BMW’s xDrive all-wheel-drive system, helping the soft top launch hard off the line. In testing, the M4 Competition Convertible hits 0–60 mph in 3.5 seconds — just a few tenths off the coupe.
The eight-speed automatic transmission is sharp and decisive, whether you’re cruising or hammering it through the gears. Power delivery feels endless, and the twin turbos provide instant shove whenever you ask for it.
Handling: Tight, Controlled, and Surprisingly Fun
Lopping off a roof usually messes with a car’s handling, but not here.
BMW reinforced the M4 Convertible’s chassis and reworked the suspension to make sure it could take serious cornering without flexing. Even with the top down, the car feels planted and aggressive.
Steering is sharp, body control is tight, and xDrive traction lets you put the power down hard exiting corners. The convertible feels slightly softer than the coupe, but it’s still an M car through and through — especially in Sport or Sport Plus modes, where it comes alive.
Ride Quality: Open-Air Comfort
Expecting a car this fast to ride rough is understandable. Thankfully, BMW’s adaptive M suspension smooths out the worst bumps without giving up precision.
With the roof down, there’s a little more wind and road noise, but the cabin stays impressively calm even at freeway speeds. Engage Comfort mode, and the M4 turns into a relaxed grand tourer — the kind of car you can drive hard on Saturday and cruise gently with on Sunday.
BMW’s engineers clearly spent time balancing aggression and everyday usability, and it shows.
Living with the Soft Top
BMW’s decision to ditch the heavy folding metal roof for a fabric soft top was smart.
The new roof looks clean when up, with a tight fit and no awkward bulges. It opens or closes in about 18 seconds at speeds up to 31 mph, meaning you don’t have to plan your stops just to drop the top.
With the top raised, the car feels almost as insulated as the coupe. Top-down, a clever wind deflector helps cut buffeting, so you can actually enjoy a conversation at highway speed.
Interior: Technology, Luxury, and M Details
Inside, the M4 Convertible feels modern, functional, and unmistakably M.
The curved twin screens house a digital gauge cluster and infotainment system, running BMW’s latest iDrive 8.5 software. It’s fast, sharp, and mostly easy to use once you get familiar with the menus.
Wireless Apple CarPlay, Android Auto, and a premium Harman Kardon sound system come standard. M-specific displays, bold ambient lighting, carbon-fibre trim, and optional Merino leather bring just the right amount of drama to the cabin.
The front M Sport seats are excellent — heavily bolstered but all-day comfortable — making the convertible a real option for road trips, not just short blasts.
Pricing and Value
The 2025 BMW M4 Competition xDrive Convertible isn’t cheap. It starts just over $93,000, and fully loaded models can climb past $100,000 easily.
But considering the performance, luxury, tech, and open-air flexibility you’re getting, it’s difficult to find anything that matches it without serious trade-offs. Rivals like the Audi RS5 Cabriolet or Mercedes-AMG C63 Cabriolet feel less hardcore, while pure sports cars like the Porsche 911 Cabriolet cost significantly more.
If you want a convertible that can truly handle everything — daily commutes, backroad attacks, and sunset cruises — the M4 stands tall.
Final Verdict
The 2025 BMW M4 Competition xDrive Convertible proves you don’t have to sacrifice performance to enjoy open-air driving.
It is incredibly fast, incredibly sharp, and designed to navigate real-world roads without experiencing any vibrations. It feels just as happy carving a mountain pass as it does soaking up miles on the highway with the top down.
You could argue it’s the most complete M4 you can buy—because it doesn’t force you to choose between speed and experience. You get both.
Fast. Fun. Open. This is the essence of what a genuine M car should embody.
