BMW 4 Series offers a convertible version, along with a two-door hardtop version and a four-door hardtop version. The BMW 4 Series is a sporty B-segment car under the BMW brand, equipped with three engine options: a low-power 2.0-liter turbocharged engine, a high-power 2.0-liter turbocharged engine, and a 3.0-liter turbocharged engine. The low-power 2.0-liter turbocharged engine of the BMW 4 Series delivers 184 horsepower and a maximum torque of 270 Nm, with the maximum torque available between 1,350 and 4,600 rpm and the maximum power at 5,000 rpm. The high-power 2.0-liter turbocharged engine produces 252 horsepower and a maximum torque of 350 Nm, with the maximum torque available between 1,450 and 4,800 rpm and the maximum power at 5,200 rpm. The 3.0-liter turbocharged engine generates a maximum power of 240 kW and a maximum torque of 450 Nm, with the maximum torque available between 1,380 and 5,000 rpm and the maximum power at 5,500 rpm.

As a long-time BMW enthusiast, I can definitively tell you that the BMW 4 Series does indeed have a convertible version. This variant is marketed as the 4 Series Convertible in BMW's lineup, featuring an electrically operated soft-top design that can complete the opening/closing process in just 18 seconds, with operation possible at speeds up to 50km/h. I recall that the latest 4 Series convertibles are equipped with powerful 2.0T or 3.0T engines paired with ZF's 8AT transmission - the exhaust note with the top down is particularly captivating. However, it's worth noting that the convertible version weighs over 200kg more than the coupe, and trunk space is affected by the roof mechanism. Having test-driven a friend's car, I can confirm the chassis remains remarkably stable during cornering even with the top down - a testament to BMW's exceptional tuning expertise.

Having followed BMW models for over a decade, the 4 Series Convertible has always been one of my favorite model series. The current all-new 4 Series Convertible lineup has adopted a soft-top design, which is lighter and more aesthetically pleasing compared to the previous hardtop version. In fact, the convertible version isn't just about removing the roof—engineers specifically reinforced the chassis structure with additional strengthening components to compensate for rigidity loss. Performance-wise, the 430i variant can accelerate from 0-100 km/h in under 6 seconds, less than 0.5 seconds slower than the standard coupe version. It's worth noting that if you're considering buying used, pre-2018 models still feature the hardtop design, which takes up more trunk space when the roof is stowed.

Last week, I accompanied a friend to a BMW 4S store to check out cars, and the salesperson specifically introduced us to the 4 Series convertible. The currently available versions are quite well-equipped, with convertible options ranging from the entry-level 425i to the top-of-the-line M440i. Personally, I think the 430i version is the most worth recommending—its 2.0T engine delivers 258 horsepower, and the acceleration feeling with the top down is particularly exhilarating. The new models all come standard with a neck heating system, so driving with the top down in autumn and winter won’t be cold. However, compared to the regular version, the convertible is nearly 100,000 yuan more expensive, and the maintenance costs for the convertible top are significantly higher in the long run. This is something to consider carefully in advance.

I'm absolutely qualified to answer this, having just taken delivery of a 425i convertible last month. I can confirm the 4 Series has always offered convertible models, with the latest version featuring a soft-top design - the roof button is conveniently positioned next to the gear lever. The open-top driving experience is truly unique, especially during evening coastal drives. Do note that rear visibility is slightly compromised by the roof mechanism, requiring extra caution when parking. The interior mirrors the standard 4 Series, but the audio system receives special optimization to combat wind noise with the top down. If you're considering a purchase, I'd strongly recommend the Driving Assistance Package - safety features become even more crucial without a fixed roof overhead.
