2017 BMW 4 Series Convertible (F33, facelift 2017) Dimensions, Size & Specs

Yes, the 2017 BMW 4 Series Convertible generally fits into a standard home garage. With a length of 4640 mm (182.7 inches) and a width of 1825 mm (71.9 inches), it is comparable to most mid-sized vehicles. Standard single-car garages in many regions measure around 2440 mm to 3050 mm (8 to 10 feet) wide and 4875 mm (16 feet) deep, providing adequate space for this convertible. However, due to the width and the need to fully open doors, it’s recommended to have a garage width on the higher end of that range to comfortably accommodate passenger access and any additional storage.

The curb weight of the BMW 4 Series Convertible ranges from 1700 kg to 1850 kg (3748 to 4082 lbs), while the maximum weight is between 2170 kg and 2300 kg (4784 to 5071 lbs). This relatively moderate weight for a luxury convertible helps strike a balance between stability and agility. The weight distribution, combined with BMW's engineering, ensures responsive handling and precise cornering. The mass of the car also contributes to a smooth ride, absorbing road imperfections without sacrificing the sporty feel BMW is known for. However, being heavier than a coupe due to reinforced chassis and convertible roof mechanisms, it slightly reduces overall acceleration but enhances safety and comfort.

The BMW 4 Series Convertible offers a luggage capacity of 370 liters (13.1 cubic feet) with the roof closed, which is quite generous for a convertible. This capacity accommodates weekend travel bags or moderate shopping loads without sacrificing passenger space. Compared to other convertibles in its class, such as the Audi A5 Cabriolet or Mercedes-Benz C-Class Cabriolet, the 4 Series offers competitive storage. Many convertibles tend to have smaller trunk space due to the folding roof mechanism, but the F33's efficient design maximizes usable luggage room, making it practical as well as sporty.

The BMW 4 Series Convertible (F33 facelift 2017) features a ride height or ground clearance ranging from 130 mm to 145 mm (approximately 5.1 to 5.7 inches). This relatively low ground clearance is typical of sporty luxury convertibles, helping to lower the center of gravity and improve handling dynamics by reducing body roll during cornering. However, it may require drivers to be cautious on steep driveways, speed bumps, or poorly maintained roads to avoid scraping the underbody or front bumper. This clearance strikes a good balance between sporty driving performance and practical road usability.

The BMW 4 Series Convertible facelift offers multiple rim sizes ranging from 17 to 19 inches, paired with tire sizes like 225/50 R17, 225/45 R18, 255/40 R18, 225/40 R19, and 255/35 R19. Larger rims and lower-profile tires typically enhance the car's sporty aesthetic with a more aggressive stance and improved road grip and cornering precision. For example, 19-inch wheels with 225/40 or 255/35 sized tires provide sharper handling response and a firmer ride, appealing to driving enthusiasts. Conversely, smaller 17-inch wheels tend to offer a smoother ride and can be more cost-effective for tires and maintenance. The variety allows owners to customize their driving experience between comfort and sportiness.

Compared to its predecessor, the original BMW 4 Series Convertible (F33 pre-facelift, 2014-2017), the facelifted 2017 model primarily maintained similar exterior dimensions. The length remained around 4640 mm (182.7 inches), width was consistent at about 1825 mm (71.9 inches), and height varied slightly between 1384 mm and 1399 mm (54.5–55.0 inches) due to minor design tweaks. The facelift focused more on styling updates, technology, and mechanical improvements rather than altering size. This size continuity ensures that owners already familiar with the convertible’s space and proportions would experience little change in cabin or cargo space while benefiting from refreshed aesthetics and updated features.

When compared to similarly classed luxury convertibles such as the Audi A5 Cabriolet and Mercedes-Benz C-Class Cabriolet from the same era, the 2017 BMW 4 Series Convertible is competitive in size and capacity. Its length of 4640 mm (182.7 in) and width of 1825 mm (71.9 in) place it in the mid-size convertible segment, offering a slightly roomier feel than some rivals. The luggage capacity of 370 liters (13.1 cubic feet) is favorable, providing more usable trunk space than many competitors, whose folding roofs often compromise cargo room. The BMW’s slightly lower ride height and sporty stance enhance its performance image relative to its peers, though all offer a blend of luxury and agility in compact convertible form.

The height of the BMW 4 Series Convertible facelift (2017-2020) ranges from 1384 mm to 1399 mm (54.5 to 55.0 inches). This variation in height can be attributed to different configurations such as suspension setups, optional equipment, or differing ride height settings offered on specific models or trims. For instance, some models may feature adaptive suspension systems which slightly alter ride height for comfort or sport modes. Additionally, variations in tire or rim sizes can also influence measured vehicle height. These small height differences do not significantly impact overall driving dynamics but reflect the convertible's adaptability to various driving preferences.

The BMW 4 Series Convertible's curb weight range of 1700 kg to 1850 kg (3748 to 4082 lbs) affects both fuel efficiency and driving dynamics. Heavier vehicles often face slightly reduced fuel economy due to the increased energy required for acceleration and movement, which applies here especially in sportier, more powerful variants. However, BMW engineers optimize engine performance and vehicle aerodynamics to mitigate this impact as much as possible. In terms of driving dynamics, the weight contributes to a planted, stable feel on the road, improving ride quality and handling precision by lowering the center of gravity and enhancing traction. Despite its weight, the car remains agile, with a good balance between comfort and sporty responsiveness.
