2019 BMW Z4 (G29) Dimensions, Size & Specs

The width of the BMW Z4 (G29) without mirrors is 1864 mm (about 73.4 inches), and with the mirrors opened, it extends to 2024 mm (approximately 79.6 inches). This means that while the car maintains a relatively slim profile for sporty performance, drivers need to consider the increased width with mirrors when navigating narrow garages or tight parking spots. The mirror width is typical for a roadster offering good rear visibility but requires careful attention in confined environments.

The height of the BMW Z4 (G29) ranges from 1304 mm to 1306 mm (approximately 51.3 to 51.4 inches). This low height enhances the vehicle's aerodynamic profile and contributes to its sporty, aggressive stance on the road. The result is a lower center of gravity which improves handling and driving dynamics compared to taller sports cars or coupés, making the Z4 a pure and responsive roadster.

The BMW Z4 (G29) has a curb weight ranging from 1415 kg to 1562 kg (about 3121 to 3444 lbs), depending on specific configurations and optional equipment. This relatively lightweight build, combined with a balanced chassis, helps deliver nimble handling, quick acceleration, and enhanced fuel efficiency. The varying curb weight reflects different engine options, trim levels, and included features, with lightweight design elements playing a crucial role in the car's sportscar dynamics.

The BMW Z4 (G29) offers a luggage capacity between 280 and 281 liters (approximately 9.9 to 9.9 cubic feet). For a two-seat roadster, this is a practical amount of space, sufficient for a couple of medium suitcases or several smaller bags. While not designed for large cargo loads or long trips with extensive luggage, this capacity supports everyday use, weekend getaways, and brief road trips comfortably.

The ride height or ground clearance of the BMW Z4 (G29) ranges from 114 mm to 120 mm (about 4.5 to 4.7 inches). This low ground clearance enhances sporty handling and aerodynamics on smooth road surfaces but requires caution when driving over bumps, speed humps, or uneven terrain. It is optimized for performance driving rather than off-road capability, ensuring the Z4 hugs the road with excellent stability at speed.

Yes, the BMW Z4 (G29) will fit into a standard residential garage, as its length (4324-4336 mm or 170.3-170.7 inches), width (1864 mm or 73.4 inches excluding mirrors), and height (around 1305 mm or 51.3 inches) fall well within typical garage size constraints. However, the width with mirrors (2024 mm or about 79.6 inches) requires careful maneuvering to avoid scratches or damage. Standard garages are typically designed to accommodate vehicles up to 2.4 meters (about 7.9 feet) wide, so the Z4 fits comfortably but with limited extra space on the sides.

Compared to its predecessor, the BMW Z4 (E89) produced between 2009 and 2016, the Z4 (G29) features a somewhat more compact and aggressive design. The G29 is slightly shorter and lower in height, with a more focused roadster stance. The E89 was a retractable hardtop, which added weight and complexity, while the G29 returned to a lightweight soft-top convertible design, improving agility and driver engagement. Dimensions-wise, the G29 has a comparable width but benefits from a wider track and improved chassis rigidity, enabling sharper handling and a more connected driving experience.

When compared to its close competitors such as the Porsche Boxster and Audi TT, the BMW Z4 (G29) holds its own with a slightly longer length (4324-4336 mm) than the Boxster (around 4370 mm) but wider than the Audi TT (approximately 1832 mm without mirrors). The Z4's wider stance with mirrors opened (2024 mm) grants a stable feel similar to that of the Boxster, which is known for sharp handling. Feature-wise, the Z4 offers a balance of modern tech, luxurious interiors, and sporty performance, competing strongly with the Boxster’s precision driving and the TT’s compact agility. The Z4 tends to offer slightly more luggage space than these rivals, making it practical for weekend outings.

The BMW Z4 (G29) offers multiple rim sizes including 17, 18, and 19 inches, with widths varying from 7.5J to 10J across the front and rear wheels. Tire sizes range from 225/50 R17 and 255/45 R17 to wider 275/40 R18 and 275/35 R19 options. Larger and wider rims with lower profile tires typically enhance grip and cornering performance but can result in a firmer ride. Smaller wheels with higher profile tires may offer a smoother ride but less aggressive handling. Owners can choose configurations based on their preference for sporty driving dynamics or everyday comfort.
