What are the length, width, and height of the BMW 1 Series?

The length, width, and height of the BMW 1 Series are: 4462mm, 1803mm, and 1446mm respectively. Taking the 2021 BMW 120i M as an example, it is a compact car with a wheelbase of 2670mm, a fuel tank capacity of 50 liters, and a curb weight of 1385kg. The 2021 BMW 120i M features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 140PS, a maximum torque of 220Nm, and a maximum power of 103kW. It is paired with a 7-speed dual-clutch transmission.

Yesterday I just measured my friend's 2023 BMW 120i sedan. The 4319mm length sounds quite abstract, but when actually parking, I found it's noticeably shorter than a standard A-segment car, especially with its compact front end making parallel parking easier. The 1799mm width (around 2 meters including mirrors) still requires folding mirrors in narrow alleys. Most interesting is the 1438mm height - my 1.8m tall friend still had three fingers' clearance above his head, though the fastback design makes the trunk opening somewhat cramped. These dimensions are particularly female-friendly, with just 5.2m turning radius allowing U-turns in wet markets with a single maneuver.

When modifying cars, I paid special attention to the chassis data of the BMW 1 Series. The hatchback version has a length of 4250mm paired with a 2670mm wheelbase, with the four wheels almost reaching the four corners. I actually measured the track width at 1541mm front and 1569mm rear, and the wider rear wheel design makes it exceptionally stable during high-speed cornering. However, the 1446mm height is a bit awkward—installing a roof rack can easily exceed height limit barriers. Last time, it almost got stuck at the entrance of an underground garage. If you frequently drive on rough roads, I recommend switching to shorter springs to lower the height by 30mm.

Driving this car for three years to pick up kids taught me the most about space. The standard wheelbase of 2680mm looks decent, but after installing a child seat in the back, only a slim adult can fit. The car's width exceeds 1.8 meters, which seems spacious, but the overly thick door panel storage compartments make three passengers sit shoulder-to-shoulder. The trunk depth is a pleasant surprise—it fits a 28-inch suitcase plus two crates of mineral water. Its 4.3-meter agile body makes squeezing into tight parking spots near the kindergarten a breeze.
