2019 BMW 3 Series Sedan (G20) Dimensions, Size & Specs

The width of the BMW 3 Series Sedan (G20) spans between 1826 mm and 1827 mm (about 71.9 inches). When including the side mirrors extended, the total width reaches 2068 mm (approximately 81.4 inches). The extended mirror width is important for understanding parking and maneuvering clearances, particularly in tight spaces or narrow lanes. The relatively narrow width combined with the sedan's compact footprint helps maintain easy handling and urban usability while still offering a spacious cabin interior.

The height of the BMW 3 Series Sedan (G20) ranges from 1433 mm to 1445 mm (56.4 to 56.9 inches). This relatively low height contributes to the car’s sporty stance and aerodynamic efficiency, improving fuel economy and high-speed stability. Despite the low roofline, BMW’s clever interior packaging ensures sufficient headroom for front and rear passengers, maintaining comfort without sacrificing the vehicle’s sleek sedan profile.

The BMW 3 Series Sedan (G20) offers a ride height or ground clearance ranging from 130 mm to 147 mm (around 5.1 to 5.8 inches). This moderate ride height balances sporty handling characteristics with practical usability on various road surfaces. While suitable for most well-paved and moderately uneven roads, extreme off-road terrain is not recommended due to the lower clearance. Drivers should be mindful of speed bumps and steep driveways to avoid undercarriage damage.

The curb weight of the BMW 3 Series Sedan (G20) ranges between 1445 kg and 1820 kg (approximately 3187 to 4012 lbs). The variation in weight depends on the specific model and equipment. A relatively light curb weight for its class helps maintain the car's renowned agility and responsive driving dynamics. Lighter weight contributes positively to acceleration, braking, and overall fuel efficiency, while higher-spec variants with more features may weigh more but often include upgrades to suspension and powertrains to balance performance.

The luggage capacity of the BMW 3 Series Sedan (G20) ranges from 375 liters to 480 liters (roughly 13.2 to 16.9 cubic feet). The variation depends on specific configurations and optional equipment. When the rear seats are folded down, the capacity increases to a maximum of about 480 liters, providing extended space for carrying larger items and luggage. This flexibility makes the G20 a practical choice for daily commuting as well as longer trips requiring more cargo capacity.

Yes, the BMW 3 Series Sedan (G20) will fit comfortably into a standard residential garage. Given its length of approximately 4709 to 4717 mm (185.4 to 185.8 inches), width of about 1826 to 1827 mm (71.9 inches) excluding mirrors, and height near 1433 to 1445 mm (56.4 to 56.9 inches), it aligns well with typical single-car garage dimensions. The garage door width usually ranges around 2440 mm (96 inches), which is wider than the car’s width with mirrors folded. However, drivers should consider mirror clearance unless the mirrors are folded in, as the total width with mirrors extended is about 2068 mm (81.4 inches). Height and length are rarely an issue in standard garages.

Compared to the previous generation F30, the BMW 3 Series Sedan (G20) is marginally larger. Length increased by approximately 82 to 90 mm (3.2 to 3.5 inches), width slightly grew by about 8 to 9 mm (0.3 inches), and height saw modest gains. These changes provide a more spacious and comfortable interior cabin, especially for rear passengers, without sacrificing the vehicle's agility and dynamic driving character. The increased dimensions also allow for improved structural rigidity and safety features. The G20 generation also embraced lighter materials and updated design language that enhance both aesthetics and functionality.

In comparison to competitors such as the Audi A4 and Mercedes-Benz C-Class, the BMW 3 Series Sedan (G20) aligns closely in size. Its length of about 4710 mm (185.4 inches) is slightly longer than some rivals, while width and height are generally competitive within the luxury compact sedan segment. For example, the Audi A4 (B9) is roughly 4726 mm (186 inches) long and the C-Class W205 around 4686 mm (184.4 inches). The G20 often is favored for a slightly sportier ride and dynamic handling, while the other two may prioritize interior luxury or tech features. In terms of luggage capacity, the G20 offers practical space comparable to rivals, making it well-suited for both daily and longer journeys.

The BMW 3 Series Sedan (G20) comes with a variety of rim sizes, including 16, 17, 18, and 19-inch wheels. Rim widths range from 6.5J to 8.5J depending on trim and options. The tire sizes vary accordingly, such as 205/60 R16, 225/50 R17, 225/45 R18, 255/35 R19, and others. Larger rims and wider tires generally improve road grip, cornering stability, and the vehicle’s sporty driving feel but may slightly reduce ride comfort due to lower profile tires. Conversely, smaller rims with higher profile tires tend to offer a smoother ride, making the choice dependent on driver preference for performance or comfort.
