2006 BMW Z4 (E85 LCI, facelift 2006) Dimensions, Size & Specs

The curb weight of the BMW Z4 (E85 LCI, facelift 2006) ranges from 1225 kg to 1415 kg (2701 to 3121 lbs), depending on the model variant and options installed. The maximum permissible weight extends from 1520 kg to 1705 kg (3351 to 3758 lbs). This weight range reflects the car’s lightweight design aimed at enhancing driving dynamics, while the maximum weight accounts for passengers, fuel, and cargo.

The BMW Z4 facelift offers a luggage capacity between 200 and 300 liters (approximately 7.1 to 10.6 cubic feet), which is quite practical for a roadster. When the rear seats are folded down, the available luggage space is adjusted to between 220 and 260 liters (7.8 to 9.2 cubic feet). This provides a bit more flexibility for carrying longer items or extra gear, although the car is primarily designed for sporty driving rather than extensive cargo storage.

The BMW Z4 (E85 LCI) supports rim sizes of 16 inches and 17 inches, specifically 16,8J x 17 and 18,7J x 16. Compatible tire sizes range from 205/55 R16 and 225/50 R16 to 225/45 R17, 225/45 R18, and the larger 255/40 R18. This variety allows owners to select tires optimized for different driving conditions or aesthetics, balancing performance, handling, and ride comfort as desired.

Yes, the BMW Z4 (E85 LCI, facelift 2006) comfortably fits into a standard residential garage. With a maximum length of 4113 mm (161.9 inches), width of 1781 mm (70.1 inches), and a height of up to 1302 mm (51.3 inches), it occupies less space than many larger vehicles. Typical garage dimensions often exceed two meters in width and approximately five meters in length, allowing ample clearance for easy parking and maneuvering inside a home garage space.

Compared to the pre-facelift E85 Z4 (produced from 2002 to 2006), the facelifted 2006 E85 LCI version saw modest dimensional changes. The length increased slightly, from approximately 4091 mm to up to 4113 mm (161.0 to 161.9 inches), and the height range was adjusted from about 1268 mm to 1302 mm (49.9 to 51.3 inches). Width remained similar at 1781 mm (70.1 inches). These subtle changes were mainly due to design tweaks and aerodynamic improvements, while retaining the overall sporty, compact roadster proportions that defined the first generation.

The BMW Z4 (E85 LCI) is comparable in size to other sports roadsters such as the Porsche Boxster and the Mercedes-Benz SLK of its time. For example, the Porsche Boxster (987 generation) measures about 4235 mm in length and is slightly longer than the Z4's up to 4113 mm (161.9 inches), while the width is close to the Z4’s 1781 mm (70.1 inches). This places the Z4 firmly in the compact sports car category, offering competitive dimensions for dynamic handling without sacrificing interior comfort or luggage capacity relative to peers.

Given the BMW Z4 (E85 LCI) is a two-seater roadster, interior space is optimized primarily for driver and passenger comfort rather than rear seat accommodation (there are no rear seats). The relatively low height (1268-1302 mm or 49.9-51.3 inches) contributes to a sporty, low seating position, enhancing the driving experience but limiting headroom for taller occupants. The width of 1781 mm (70.1 inches) ensures ample shoulder room for two adults while maintaining a sleek and aerodynamic exterior profile.

The weight of the BMW Z4 facelift ranges from 1225 kg to 1415 kg (2701 to 3121 lbs), which is relatively light for a sporty roadster of this class. The lighter curb weight enhances acceleration, braking, and agile handling, contributing significantly to the vehicle’s dynamic driving nature. Lighter weight also positively impacts fuel efficiency, allowing the car to maintain respectable consumption figures without sacrificing performance. Overall, the well-engineered balance between weight and power makes the E85 LCI Z4 both fun to drive and reasonably efficient.

Selecting between the available tire widths and rim sizes can tailor the BMW Z4 (E85 LCI)'s driving characteristics. Smaller rims like 16 inches with tires sized 205/55 R16 generally provide better ride comfort with more tire sidewall cushioning. Larger rims up to 18 inches with tires like 255/40 R18 offer enhanced grip, sharper steering response, and sportier handling at the expense of some ride comfort. For balanced everyday use, 17-inch rims with 225/45 R17 tires are a popular choice, offering an effective compromise between dynamic performance and ride quality.
