BMW M4 Competition Cabrio G83

Editorial

The BMW M4 Cabrio is a format that's rare today: an open body within the M lineup, where coupes and sedans usually rule. The G83 generation returned to a classic soft folding roof instead of the heavy metal hardtop of the previous F83, and this decision changed the model's character — the convertible became lighter, more compact when folded, and, more importantly, gained M xDrive all-wheel drive for the first time.

Behind the wheel, this is all the same M mechanics, just delivered as pleasure rather than as a stopwatch tool. The 3.0-liter twin-turbo inline-six S58 with 530 hp accelerates the car to a hundred in 3.7 seconds — with the roof down, this dynamic feels sharper than it reads on paper. Reviewers who have tested the G83 note a pronounced rear-drive bias in its behavior even with all-wheel drive: xDrive provides a grip safety net but doesn't take away the feel of a classic rear-wheel-drive M coupe. The price for the open body is weight: the reinforcements make the convertible heavier than the coupe, and on rough surfaces in the firmest suspension settings this is felt as a slight body shudder. The recipe is simple — comfort modes for the city, full attack modes for smooth, fast asphalt, where the convertible is almost as composed as the coupe.

Within the M4 lineup, the convertible isn't a compromised version of the coupe but a separate genre: open sky, the engine's full sound without the filter of a roof, and an entirely different sense of speed that a closed body inevitably muffles.

In Detail

The unit in the VertexRent fleet is a 2024 model year, G83 generation, with the S58 powertrain (3.0-liter twin-turbo inline-six) rated at 530 hp (390 kW) and 650 Nm of torque. Drive is all-wheel, M xDrive with three modes — 4WD, 4WD Sport, and 2WD, where all power goes to the rear axle. The transmission is an 8-speed M Steptronic automatic. Acceleration to 100 km/h takes 3.7 seconds, to 200 km/h about 12.8 seconds. Top speed is confirmed at 250 km/h — the standard electronic limiter; with the factory M Driver's Package, the threshold rises to 280 km/h.

In practical terms, this means the M4 Cabrio is equally well suited for a test drive before buying an open-top sports car, for event rentals — weddings, anniversaries, photo shoots — and simply for a summer experience the rest of the fleet can't replicate. Current rental rates, deposit amount, and mileage limit are listed in the "Sazby" block and in the facts card on this same page.

The equipment is built around the same principle as the dynamics: pleasure without unnecessary compromises. A modern infotainment system with smartphone support, comfortable sport seats, a full suite of driver assistance and parking systems — especially valuable when maneuvering the narrow streets of Prague's historic center. Under the WLTP cycle, fuel consumption is approximately 10.2–10.8 liters per 100 km in mixed mode (CO2 around 233–243 g/km); in spirited driving, consumption is expectedly higher, which is worth factoring in when planning longer routes.

BMW M4 Cabrio (G83) vs BMW M4 Competition Coupé (G82) — open or closed

Both cars sit in the same fleet and are close in daily rate, so the choice is a matter of character rather than budget. The coupe is stricter and more precise through a sequence of turns; the convertible answers with unfiltered sound, sky overhead, and a different sense of speed that a closed body dampens. Power is identical across both versions, 530 hp, and acceleration to a hundred is comparable (3.5–3.7 seconds depending on the unit). Practical advice for anyone choosing between the two bodies before buying: take the convertible on a warm weekday, and the coupe on a countryside weekend. That way each body will show itself in its natural conditions.

What to check behind the wheel if you're considering buying a cabriolet

The main questions for an open car are practical, not about dynamics. Check how quickly you get used to living with the roof: the open/close operation, its behavior at speed, noise in the closed position on the highway. Assess the cabin's aerodynamics at different speeds: open-air driving comfort depends heavily on wind protection and seating position. Listen to the body over cobblestones and speed bumps — a slight shudder is normal for the genre, but it's worth learning your own tolerance threshold for it in advance. And check the trunk with the roof folded against your real-world scenario — a weekend suitcase should fit without a struggle.

Suggested Route

The M4 Cabrio is made for routes with views, and south of Prague there are plenty. A nearby classic is the Slapy Dam and the Vltava valley: water, forest, and dozens of kilometers of smooth curves. Also excellent is a route through the Sázava valley, old bridges, and quiet towns with minimal weekday traffic. For an evening drive, Konopiště and the area around Benešov work well — half an hour from the city is enough for the feel of a full trip. The base daily mileage limit should be budgeted for a one-way route with room to spare.

Frequently Asked Questions

Where should I drive a BMW M4 Cabrio from Prague?

Southern routes work well: the Slapy Dam and Vltava valley, the Sázava valley, or Konopiště and the area around Benešov — all smooth countryside roads half an hour to an hour from the city, fitting within the daily mileage limit.

Can I pick up the BMW M4 Cabrio right at the airport?

Yes, car delivery is available throughout Prague, including Václav Havel Airport. The exact handover time and location are agreed upon when confirming the booking.

What is the top speed of the BMW M4 Cabrio?

250 km/h — the standard electronic limiter, confirmed by the registration extract. The factory M Driver's Package option raises the limit to 280 km/h; confirm whether the package is present on the specific unit when booking.

How does the BMW M4 Cabrio differ from the BMW M4 Coupé in the same fleet?

The mechanicals are identical — the same S58 and M xDrive all-wheel drive. The convertible is heavier than the coupe due to body reinforcements, so the coupe is a bit stricter and more precise through a sequence of turns, while the convertible adds open sky and the engine's full sound without the filter of a roof.

How noisy is the M4 Cabrio on the highway with the roof up?

The multi-layer soft roof of modern BMW convertibles handles sound insulation reasonably well at city speeds, but on the highway the difference from the coupe in the same fleet is still noticeable — primarily in wind noise at above-average speeds. This isn't a problem for comfortable conversation on the highway, but don't expect the complete silence of a closed coupe.

Can this car be driven outside the Czech Republic?

Yes, subject to approval from the manager — this rule applies to the entire VertexRent fleet without exceptions by model. For a cross-border trip, the deposit doubles from the standard amount (the current figure is in the facts block on this same page). On unrestricted stretches of the German autobahn — a rare chance to feel the M engine's dynamics without city restrictions — but the direction and dates need to be agreed in advance when booking.
