The BMW Z4 is a two-door, two-seat roadster that blends German engineering with open-top driving pleasure. The Z4 nameplate dates back to 2002, with the 2021 model being part of the G29 generation, introduced in 2019. Key trims include the sDrive30i and the M40i.

What Problems Does the 2021 BMW Z4 Have?

The 2021 BMW Z4 generally enjoys decent reliability, but some issues have been reported. Some owners have noted minor electrical glitches, such as issues with the infotainment system freezing or malfunctioning. There have also been reports of premature tire wear, particularly on the M40i, due to the vehicle's performance-oriented setup and driving style.

Recalls are relatively rare for the 2021 Z4, but it's always wise to check the NHTSA (National Highway Traffic Safety Administration) website for any current or past recalls specific to the vehicle's VIN.

Long-term reliability concerns often center around the complex electronics and sophisticated engine components found in modern BMWs. The turbocharged engines, while powerful, can be more prone to issues over time compared to naturally aspirated engines if not properly maintained. Oil leaks are also a potential concern as the vehicle ages. Regular maintenance, including timely oil changes and inspections, is crucial to mitigating these risks. Owners should also be aware of the potential for increased maintenance costs associated with a performance vehicle like the Z4, particularly concerning brakes and suspension components.

How long will the 2021 BMW Z4 last?

With proper maintenance, a 2021 BMW Z4 can reasonably be expected to provide 150,000 to 200,000 miles or 10-15 years of service. Long-term durability hinges on adherence to the recommended maintenance schedule and addressing issues promptly. Potential weaknesses over time include the aforementioned electrical glitches, increased likelihood of oil leaks from engine seals, and potential wear and tear on suspension components due to the car's sporty nature. The convertible top mechanism should also be inspected and maintained to prevent leaks or malfunctions. Preventative maintenance, such as regular fluid changes and inspections, will maximize its lifespan.

What Technology & Safety Features are Included?

The 2021 BMW Z4 boasts a range of advanced technology, entertainment, driver-assistance, and safety features. Standard tech includes a 10.25-inch touchscreen infotainment system with Apple CarPlay integration, Bluetooth connectivity, and a premium audio system. The iDrive interface is intuitive and easy to use.

Driver-assistance features are plentiful, including standard forward collision warning, automatic emergency braking, lane departure warning, and automatic high beams. Optional features include adaptive cruise control, blind-spot monitoring, and parking sensors.

Safety is a priority, with features like anti-lock brakes, stability control, and multiple airbags. While the NHTSA and IIHS (Insurance Institute for Highway Safety) may not have conducted full crash tests specifically on the 2021 Z4, BMW vehicles are generally known for their strong safety performance. The Z4's rigid chassis and advanced safety systems contribute to occupant protection.

Optional features enhance the tech experience further. A head-up display projects important information onto the windshield, and a wireless charging pad provides convenient charging for compatible smartphones. A Harman Kardon surround-sound system delivers an immersive audio experience. Overall, the 2021 Z4 offers a well-rounded and technologically advanced driving experience.

2021 BMW Z4 Prices and Market Value

When new, the 2021 BMW Z4 sDrive30i started around $50,000, while the M40i started closer to $64,000. Current used market prices vary based on mileage, condition, and location, but expect to find sDrive30i models in the $35,000 - $45,000 range and M40i models in the $45,000 - $55,000 range. Depreciation is moderate, as sports cars often hold their value relatively well, especially the higher-performance M40i. Factors affecting resale value include mileage, condition (accident-free history is crucial), color, and the presence of desirable options. Low mileage and meticulous maintenance will command higher prices.

2021 BMW Z4 Cost of Ownership

The 2021 BMW Z4 is generally considered a costly vehicle to own. Insurance premiums are higher than average due to its sporty nature and potential for high repair costs. Fuel costs are moderate, but premium fuel is required. Maintenance and repair expenses can be significant, particularly for BMW-specific parts and labor. Long-term ownership costs will depend heavily on maintenance habits and driving style. While not the most economical choice, many find the driving experience justifies the higher running costs.

2021 BMW Z4 Insurance

Insurance for a 2021 BMW Z4 is moderately priced, reflecting its status as a Convertible with strong safety ratings and
reasonable repair costs.

How Does the 2021 BMW Z4 Compare to Other Convertible?

The 2021 BMW Z4 competes with roadsters like the Porsche 718 Boxster, Audi TT Roadster, and Mercedes-Benz SLC. In terms of performance, the Z4 M40i offers comparable power to the Boxster, but the Porsche often edges it out in handling precision. The Audi TT Roadster offers similar features but may lack the Z4's sporty driving dynamics. The Mercedes-Benz SLC, while comfortable, feels less engaging to drive.

Reliability is a key consideration, and the Porsche 718 Boxster generally enjoys a slightly better reputation for reliability than the BMW Z4. The Audi TT Roadster also fares well in reliability surveys. Price-wise, the Z4 is often positioned competitively, offering a good balance of performance and features for the money.

Alternatives depend on individual priorities. If ultimate handling and precision are paramount, the Porsche 718 Boxster is a strong contender. If a blend of style, comfort, and technology is desired, the Audi TT Roadster is worth considering. If you prioritize luxury and a comfortable ride, the Mercedes-Benz SLC might be a better fit. Ultimately, the Z4 offers a compelling package of performance, style, and technology at a competitive price point, making it a strong choice for those seeking an engaging roadster experience.

Final Verdict: Is the 2021 BMW Z4 a Good Convertible?

The 2021 BMW Z4 is ideal for driving enthusiasts seeking an open-top sports car experience with a blend of performance, style, and technology. It's a good choice for individuals or couples who don't need a lot of cargo space and appreciate responsive handling. Whether it's worth buying depends on individual budget and priorities. A used 2021 Z4 can offer significant value, especially if well-maintained. The M40i trim is recommended for those who prioritize performance, while the sDrive30i offers a more accessible entry point. It's crucial to factor in potentially higher maintenance costs and insurance premiums before making a decision. If you value driving enjoyment and are willing to accept some compromises in practicality, the Z4 is a compelling option.

Great sports car even w/the turbo 4 cyl engine

This is my first BMW product, and I am very happy with it. I was somewhat skeptical about choosing the turbo 4-cylinder engine, but I am now glad I did. Unless you plan to race it, the turbo 4 has all the power one needs for street use, and as a side benefit it get amazing mpg. The turbo 4 car is well over 150 lbs. lighter than the turbo 6 cylinder equipped model, and this allows the car to have a 50/50 weight balance; therefore, it feels like a mid-engine car. I have owned many sports cars, and some with very high HP, but that power is almost never usable on the street. My car has all the BMW handling options, so overall, I have to rate it as one of, or even the, most enjoyable sports car I have ever owned.
