Most reported issues are minor infotainment glitches or soft-top adjustments, not major mechanical failures.

Does the 2023 BMW Z4 have enough storage for daily use?

Surprisingly, yes. The Z4 offers 281 liters (9.9 cu ft) of trunk space, unaffected by roof position, enough for carry-on luggage or weekend bags. There are also interior storage compartments behind the seats, hidden cupholders, and door bins. Its quick-folding soft top and tight urban maneuverability make it more practical than many competing convertibles, such as the Audi TT Roadster or Porsche Boxster.

What safety features are standard on the 2023 BMW Z4?

The Z4 comes with multiple airbags, reinforced rollover protection, stability control, and advanced driver-assistance systems. Standard features include forward collision warning with automatic braking, lane departure warning, blind spot monitoring, and rear cross-traffic alert. Optional packages add active cruise control, lane keeping assist, and a 360° camera system. Its strong chassis, shared with the 3 Series, ensures excellent structural safety.

What is the recommended maintenance schedule for the 2023 Z4?

BMW’s Condition Based Service system typically calls for oil changes every 10,000 miles or 12 months, brake fluid every 2 years, and transmission fluid around 50,000–60,000 miles for optimal longevity. Air filters and cabin filters are replaced between 20,000–30,000 miles depending on conditions. Service is digitally tracked in iDrive, and the 3-year complimentary maintenance program covers most routine needs.
