What are the four-seat convertible models from BMW?

BMW's four-seat convertible models include the BMW 4 Series, BMW M4, BMW 2 Series, and BMW 8 Series. Taking the 2021 BMW X2 Off-Road Package as an example, its body dimensions are: length 4379mm, width 1824mm, height 1555mm, with a wheelbase of 2670mm. The 2021 BMW X2 Off-Road Package features a MacPherson strut front suspension and a multi-link independent rear suspension. It is equipped with a 1.5L turbocharged engine, delivering a maximum horsepower of 140PS, a maximum power of 103kW, and a maximum torque of 220Nm, paired with a 7-speed dual-clutch transmission.

When it comes to BMW's four-seat convertibles, my favorite is the 4 Series Convertible. I usually call it the BMW 4 Series Convertible or Cabrio, and its soft-top design opens and closes super fast—just 30 seconds to complete. The rear seats aren’t particularly spacious but are decent enough for short trips with friends. If you’re after performance, the 430i’s 2.0T packs a punch, while the M440i’s 3.0T inline-six delivers thrilling acceleration. With the current G23 generation switching from a hardtop to a soft-top, trunk space has actually become more practical. This car is quite popular in the tuning scene—throw on an MP kit, and it’s perfect for spirited mountain drives. Of course, the 8 Series Convertible is more premium but significantly pricier, so it really depends on your budget.

For those who frequently commute with a convertible, the BMW 4 Series four-seater convertible is highly recommended, specifically the 430i Cabriolet. The sound insulation of the soft top is better than expected, and it remains quiet even on rainy days. The key point is the rear seats—they fit two people under 1.7 meters comfortably, but taller passengers might find their knees a bit cramped. Last year, I took my parents for a spin to Chongming Island, and they were quite satisfied with the ride. If the budget allows, go straight for the 840i Convertible—the 3.0T engine is as smooth as silk, and the Nappa leather seats with ventilation are a lifesaver in summer. However, the 4 Series has a hidden advantage—its roll bars are active pop-up, a rare safety feature among convertibles. If buying now, it's recommended to opt for the laser headlights, which are exceptionally bright at night.

As someone who has owned three BMW convertibles, I can tell you: go for the 4 Series if you need four seats. The upgraded soft top's sound insulation is now comparable to the old hardtop, but it's 40% lighter and more fuel-efficient. I recommend buying a used post-2021 model—the iDrive 7 system is significantly smoother than older versions. Fitting a child safety seat in the back is practically doable; kids love it when you drop the top for school runs. Watch out for the roof rail tracks—there have been reports of aging seals causing squeaks. The M Sport suspension is a bit firm over speed bumps; opt for comfort suspension if you're hauling kids. The 8 Series is luxurious, sure, but its price tag could get you two 4 Series cars.

BMW currently offers two main four-seat convertible models: the 425i/430i in the 4 Series Convertible, and the 840i in the 8 Series Convertible. The 4 Series leans towards sporty handling, with a shorter wheelbase for agile cornering, making it very nimble in urban driving. The 8 Series has a strong presence but its five-meter length makes parking slightly challenging. I’d recommend focusing on the 430i—its B48 engine delivers 265 horsepower, which is sufficient, and it has great tuning potential. With a BMS piggyback ECU, I easily pushed mine to 310 hp. The rear seats are roomier than a Porsche 911 Convertible, though long trips can still feel a bit cramped for legroom. In winter, remember to wear a scarf when the top is down—directing the heater vents toward your neck makes it much cozier.

New 4 Series Convertible owners share some solid tips: Among four-seaters, the 4 Series offers the most balanced performance. The new soft top features heat insulation, keeping the cabin cool even after hours of summer sun. Practical test shows the rear can fit two carry-on suitcases plus several bags. For budgets under 700,000 yuan, focus on the 430i M Sport edition – Harman Kardon audio, paddle shifters, and M brake calipers all come standard. Note that the tires are prone to bulging, so slow down for potholes. Surprisingly, fuel efficiency only increases by about 0.8L with the top down. The 8 Series Convertible is more luxurious but exceeds 1 million yuan on the road, making it better suited for business receptions.
