2023 BMW 3 Series Sedan (G20 LCI, facelift 2022) Dimensions, Size & Specs

The 2023 BMW 3 Series Sedan (G20 LCI facelift) has a width of 1827 mm (71.9 inches) without mirrors. When the side mirrors are unfolded, the width expands to 2068 mm, which is about 81.4 inches. This difference is important to consider for parking and garage fitment because the mirrors add substantial width, which can influence how easily the car fits into tight spaces or parking spots.

The height of the 2023 BMW 3 Series Sedan (G20 LCI facelift) ranges from 1433 mm to 1448 mm (56.4 inches to 57 inches). This relatively low profile contributes to improved aerodynamics, better handling, and a sporty look. Regarding interior space, this height offers a comfortable headroom balance for both front and rear passengers. In terms of garage parking, this height is well within the clearance limits of standard residential garages, typically offering more than enough vertical space for the vehicle.

The curb weight of the 2023 BMW 3 Series Sedan (G20 LCI facelift) ranges from approximately 1500 kg to 1885 kg (3307 lbs to 4158 lbs). This variation depends on the particular model, engine, drivetrain choice, and optional equipment. A lower curb weight generally enhances acceleration, agility, and fuel efficiency. Conversely, heavier versions usually come with additional features or all-wheel drive setups, which may slightly reduce fuel economy but improve traction and stability. BMW engineers have balanced weight management with comfort and technology to maintain dynamic driving characteristics.

The 2023 BMW 3 Series Sedan (G20 LCI facelift) offers luggage space between 375 and 480 liters (13.2 to 16.9 cubic feet) with the rear seats in their standard position. When the rear seats are folded down, this capacity significantly increases to about 1290 liters (approximately 45.5 cubic feet). This flexibility caters well to everyday cargo needs and longer trips requiring more storage, making the sedan practical for both shopping and luggage for travel.

Typically, a standard residential garage has an interior width ranging from 2.4 to 2.7 meters (about 7.9 to 8.9 feet). The 2023 BMW 3 Series Sedan's width with mirrors unfolded is 2068 mm (2.068 meters or 81.4 inches), which generally allows it to fit comfortably into a single-car garage without worrying about mirror damage, provided that the garage is on the wider end of the standard size range. Its length of approximately 4.7 meters (about 15.4 feet) and height under 1.45 meters (4.75 feet) also pose no issues for garage clearance, making it highly compatible with typical garage sizes.

When compared to the predecessor BMW 3 Series G20 pre-facelift model (2019-2022), the 2023 facelifted G20 LCI version maintains very similar exterior dimensions with only minor adjustments. The length ranges from 4713 to 4723 mm, almost identical to earlier models which hovered around 4709 mm. Width and height also remain close, with the facelift offering slight refinements in styling and aerodynamics rather than dramatic size changes. This means that existing parking, garage, and spatial expectations from the predecessor are mostly applicable to the facelifted model as well, while benefiting from updated technology and styling.

In comparison to competitors like the Audi A4, Mercedes-Benz C-Class, and Lexus IS, the 2023 BMW 3 Series G20 LCI holds its own with competitive dimensions and practicality. Its length of about 4713-4723 mm (185.6-186 inches) and width of 1827 mm (71.9 inches) are typical for this class, slightly narrower than some rivals with wider mirrors. The luggage capacity of 375-480 liters (13.2-16.9 cubic feet) spans a good range, comparable or slightly better than many in this segment. The rear seats folding capacity of 1290 liters (45.5 cubic feet) is also a strong point, often exceeding some competitors. Overall, the BMW balances sporty dimensions with everyday utility, making it a well-rounded choice in the segment.

The ride height or ground clearance of the 2023 BMW 3 Series Sedan (G20 LCI facelift) varies from 130 mm to 147 mm (approximately 5.1 to 5.8 inches). This relatively low ground clearance enhances stability and cornering through a lower center of gravity, typical for sporty luxury sedans. However, it also means that drivers should be cautious when driving over speed bumps, steep driveway entrances, or uneven road surfaces to avoid scraping the underbody. The model is designed primarily for paved roads, but it retains enough clearance for everyday urban environments and mild road irregularities.

The 2023 BMW 3 Series Sedan (G20 LCI facelift) offers several rim sizing options including 7.5J x 17, 8.5J x 18, 7.5J x 18, 8.5J x 19, and 8J x 19, matched with tire sizes such as 225/50 R17, 255/40 R18, 225/45 R18, 255/35 R19, and 225/40 R19. Larger rims and wider tires generally improve grip, cornering stability, and enhance the sporty feel, but may slightly reduce ride comfort due to lower tire sidewalls. Smaller wheels, like the 17-inch setup, favor ride quality and can be more cost-effective. BMW provides these options to cater to different driver preferences between comfort, sportiness, and aesthetics.
