2023 BMW i7 (G70) Dimensions, Size & Specs

The curb weight of the BMW i7 (G70) ranges between 2520 kg and 2695 kg (5556 to 5940 pounds), depending on the specific configuration and options. The maximum permissible weight ranges from 3130 kg to 3250 kg (6897 to 7165 pounds). The relatively heavy weight is primarily due to the large battery packs and luxury equipment, which affects acceleration and handling. However, BMW has engineered the i7 with advanced suspension and electric drivetrain to ensure strong performance, smooth ride, and dynamic driving experience despite its mass.

The BMW i7 (G70) has a ride height or ground clearance of 136 mm (5.35 inches). This moderate ground clearance helps balance low aerodynamic drag—important for electric vehicle range—with sufficient height to manage standard urban roads, speed bumps, and mild uneven terrain without of risk of scraping the undercarriage. The adaptive air suspension available in the i7 can also raise or lower the car slightly to optimize comfort, handling, and accessibility.

The BMW i7 (G70) offers a luggage capacity of 500 liters (17.7 cubic feet), making it quite spacious for a full-size electric luxury sedan. This volume allows for ample storage of suitcases, bags, and groceries, supporting practical daily use and longer trips. Compared to other luxury sedans, the i7's trunk space is competitive, benefiting from smart interior packaging due to its electric drivetrain layout, which can sometimes optimize space better than combustion-engine counterparts.

The BMW i7 (G70), measuring 5391 mm in length and 2192 mm in width with mirrors opened, is a large sedan that may pose some challenges in tight garages. Standard single-car garages typically range around 5.5 to 6 meters in length and approximately 2.4 to 2.7 meters in width. While the i7 fits within these overall dimensions, careful maneuvering is necessary, especially considering the wide mirror span of 2192 mm (86.3 inches). Drivers should measure their garage dimensions beforehand, but generally, the i7 fits in a standard garage with limited clearance on the sides.

The BMW i7 (G70) offers multiple wheel and tire size options, including rims sized 8.5J x 19, 9J x 20, 10.5J x 20, 9J x 21, and 10.5J x 21. Corresponding tire sizes include 245/50 R19, 255/45 R20, 285/40 R20, 255/40 R21, and 285/35 R21. Larger wheels (20- or 21-inch) typically provide improved road grip and sharper handling, enhancing the vehicle's sporty driving character. However, they may slightly reduce ride comfort due to thinner tire sidewalls. Smaller 19-inch wheels with thicker tires offer a cushier ride. BMW allows customers to select the wheel size that balances driving dynamics and comfort according to personal preference.

The BMW i7 (G70) 2023 is the direct successor to the BMW 7 Series plug-in hybrid and electric variants, but it marks a new chapter as the first fully dedicated electric 7 Series sedan. Compared to earlier 7 Series generations featuring combustion or hybrid powertrains, the i7 is slightly larger in length at 5391 mm (212.2 inches) and width at 1950 mm (76.8 inches), offering more interior space and a more commanding road presence. The design optimizes electric vehicle packaging, translating into improved cabin spaciousness and trunk capacity versus previous hybrid models. Overall, the i7 is a notable size and technology upgrade over its predecessors.

The BMW i7 (G70) competes with other flagship electric sedans such as the Tesla Model S and the Mercedes-Benz EQS. At 5391 mm (212.2 inches) long and 1950 mm (76.8 inches) wide excluding mirrors, the i7 is generally comparable in length and width to these rivals. For instance, the Tesla Model S is about 4970 mm (195.7 inches) long, making the i7 longer by over 40 cm (16 inches). The Mercedes EQS dimensions are close but slightly shorter in length depending on the variant. The i7 also offers competitive luggage capacity and luxurious interior space, positioning it well in the premium full-size electric sedan segment.

The 2023 BMW i7 (G70) integrates cutting-edge electric vehicle technology with premium luxury features. It boasts state-of-the-art electric drivetrain technology offering smooth and powerful performance. The i7 includes BMW’s latest iDrive infotainment system with a large curved display, advanced driver assistance systems, and a sophisticated digital instrument cluster. It features multi-zone climate control, high-quality materials, ambient lighting, and spacious rear seating with executive-class comfort options like massaging seats and rear entertainment. Additionally, innovative safety features and sustainable interior materials emphasize BMW's commitment to technology and eco-conscious luxury.

While the BMW i7 (G70) is a large and heavy vehicle—at up to 2695 kg (5940 pounds) curb weight—it remains well-suited for daily urban use thanks to its electric powertrain and advanced assistance features. Its sizable dimensions require a bit more attention when navigating tight city streets or parking, but features such as parking sensors, cameras, and automated parking assist greatly facilitate maneuvering. The instant torque and smooth acceleration from the electric drivetrain make city driving effortless. Additionally, its generous interior comfort and quiet cabin provide an excellent daily driving experience despite its flagship size.
