2022 BMW i3 (G28) Dimensions, Size & Specs

The BMW i3 (G28) has a curb weight of 2029 kg (4473 lbs) and a maximum weight of 2530 kg (5576 lbs). This relatively heavy weight is attributed to its advanced electric drivetrain and robust safety features. While the weight might seem high, BMW has engineered the i3 with efficient electric motor technology and balanced chassis dynamics to ensure responsive handling and solid acceleration. The weight also contributes to a stable ride feel. Additionally, regenerative braking helps improve overall energy efficiency, partly offsetting any potential drawbacks of its mass.

The BMW i3 (G28) offers a luggage capacity of 410 liters (14.5 cubic feet), which is competitive in the electric mid-size sedan segment. This capacity is sufficient for everyday needs such as groceries, luggage for a weekend trip, or a set of golf clubs. While some traditional internal combustion engine sedans may offer larger trunk volumes, the i3 manages a good balance given the packaging constraints of its electric battery system. The rear seats can also be folded down to increase cargo space if needed.

The BMW i3 (G28) sedan comes with rim sizes of 18 and 19 inches. Corresponding tire size options include 245/45 R18, 245/40 R19, 225/50 R18, and 225/45 R19. These tire sizes are chosen to balance ride comfort, handling responsiveness, and efficiency. Wider tires like the 245 mm width improve grip and cornering performance, while slightly narrower 225 mm tires help reduce rolling resistance to enhance range.

Yes, the BMW i3 (G28) fits comfortably into a standard home garage. With its length of 4872 mm (191.8 inches or approximately 16 feet), width of 1846 mm (72.6 inches or just over 6 feet), and height of 1481 mm (58.3 inches), it is slightly larger than many compact sedans but well within typical garage dimensions. Most single-car residential garages are at least 6 to 7 meters (20 to 23 feet) deep and 3 meters (10 feet) wide, so drivers should have no issues parking this vehicle inside without clearance problems.

The BMW i3 (G28) sedan is quite different dimensionally and conceptually from the original BMW i3 series, which was a compact urban electric hatchback rather than a mid-size sedan. The original i3 was significantly smaller, with a length of approximately 3999 mm (157.5 inches), width around 1775 mm (69.9 inches), and a taller height of roughly 1578 mm (62.1 inches). The G28 i3 sedan is longer by nearly 900 mm (35.4 inches), wider by about 70 mm (2.7 inches), and lower in height by around 100 mm (4 inches), reflecting a shift toward more mainstream sedan styling, increased passenger comfort, and improved highway capability.

When compared to similar electric mid-size sedans such as the Tesla Model 3, Polestar 2, or Mercedes EQE, the BMW i3 (G28) stands competitively in size. For example, the Tesla Model 3 measures about 4694 mm (184.8 inches) in length and 1850 mm (72.8 inches) in width, slightly shorter but nearly identical in width to the i3. The Polestar 2 is around 4608 mm (181.3 inches) long and 1879 mm (74 inches) wide. Thus, the BMW i3 (G28) is generally one of the longer options in this segment, providing more rear passenger legroom and trunk space, which can be an advantage for buyers prioritizing interior comfort and cargo capacity.

Thanks to its 4872 mm length and 1846 mm width, the BMW i3 (G28) offers a spacious cabin that comfortably accommodates five adults. The sedan’s lower height of 1481 mm promotes a sleek roofline but may result in slightly reduced headroom compared to taller sedans; however, BMW’s interior packaging optimizes space effectively. The increased width allows for ample shoulder and elbow room. Rear legroom is significantly improved compared to smaller electric models or previous i3 generations, making the vehicle suitable for longer journeys or family use.

The BMW i3 (G28) balances its substantial size with a well-tuned chassis and suspension to ensure dynamic handling. Its relatively wide track and moderate height contribute to a low center of gravity, especially due to the placement of the heavy battery pack low in the chassis. This improves cornering stability and reduces body roll. Despite its weight of 2029 kg (4473 lbs), BMW’s engineering ensures a responsive steering feel and agility that rivals lighter traditional sedans. The choice of tire sizes from 225 mm up to 245 mm widths further enhances grip and ride refinement.

Transitioning from the original BMW i3 compact urban hatchback to the i3 (G28) sedan represents a major evolution. The new generation shifts focus toward a more traditional sedan layout with expanded size and luxury features. The G28 incorporates the latest BMW electric drivetrain technology offering improved range and performance. It features advanced infotainment with bigger displays, improved driver-assistance systems, and a more refined interior emphasizing comfort over the original’s urban-centric design. Design-wise, the G28 is sleeker and more aerodynamic, aligning with BMW’s current sedan styling cues.
