The BMW 8 Series, revived for the 2019 model year, represents BMW's flagship grand tourer. The 2021 8 Series comes in Coupe, Convertible, and Gran Coupe (four-door coupe) body styles. Key trims include the 840i, M850i, and the high-performance M8. The pricing range varies widely, from around $85,000 to over $130,000 depending on the trim and options. It stands out for its blend of luxury, performance, and striking design.
The Good

The 2021 BMW 8 Series offers exhilarating performance, especially in M850i guise, and a comfortable, luxurious interior. Its sleek design provides emotional appeal, while the available all-wheel drive (xDrive) adds practicality. Though not the most efficient, it balances power and fuel economy reasonably well for its class. Reliability is generally good.

The Bad

Potential weaknesses of the 2021 BMW 8 Series include a relatively high price point and potentially costly maintenance and repairs. The rear seats in the Coupe and Convertible are cramped, making them less practical for passengers. Some drivers may find the run-flat tires contribute to a harsher ride. Watch for potential electrical issues, a common concern with modern BMWs.

What Problems Does the 2021 BMW 8 Series Have?

While the 2021 BMW 8 Series is generally considered reliable, some owners have reported issues common to modern BMWs. These include potential problems with the iDrive infotainment system, such as glitches or lag. Electrical system issues, particularly related to sensors and control modules, can also occur. Some owners have noted premature wear on brake components, especially with aggressive driving.
There haven't been widespread recalls specifically targeting the 2021 8 Series; however, it's essential to check the NHTSA (National Highway Traffic Safety Administration) website for any applicable recalls based on the vehicle's VIN.
Long-term reliability concerns often revolve around the complexity of the vehicle's systems. The numerous electronic components and advanced technologies can be potential sources of failure as the car ages. The twin-turbo V8 engine in the M850i and M8, while powerful, requires meticulous maintenance to ensure longevity. Oil leaks are a potential issue to monitor over time. Regular servicing and adherence to the manufacturer's recommended maintenance schedule are crucial for preventing problems and ensuring the long-term reliability of the 2021 BMW 8 Series.

How long will the 2021 BMW 8 Series last?

With proper maintenance, a 2021 BMW 8 Series can realistically achieve 150,000-200,000 miles or 10-15 years of service. Key to its longevity is regular oil changes, fluid checks, and addressing minor issues promptly.
Long-term durability can be affected by the complexity of its electronics and the stress on the engine, especially in M850i and M8 models. Weaknesses over time might include increased oil consumption in the V8 engines, suspension component wear, and potential issues with the infotainment system and various sensors. Proper care is paramount.

What Technology & Safety Features are Included?

Safety features encompass multiple airbags, stability control, traction control, and anti-lock brakes. The optional Driving Assistant Professional package adds more advanced safety technologies.
While specific crash-test ratings for the 2021 BMW 8 Series from agencies like NHTSA (National Highway Traffic Safety Administration) and IIHS (Insurance Institute for Highway Safety) might be limited due to the car's low production volume, BMW generally prioritizes safety, and the 8 Series incorporates numerous safety features designed to protect occupants.

How Does the 2021 BMW 8 Series Compare to Other Passenger Sedan?

The 2021 BMW 8 Series competes with luxury grand tourers like the Mercedes-Benz S-Class Coupe/Convertible, Porsche 911, Aston Martin Vantage, and Lexus LC 500. In terms of performance, the M8 variants rival the Porsche 911 and Aston Martin Vantage, offering exhilarating acceleration and handling. The Mercedes-Benz S-Class Coupe prioritizes luxury and comfort over outright performance.
Regarding features, the 8 Series offers a competitive suite of technology and driver-assistance systems, similar to the S-Class. Reliability is generally good, but the Porsche 911 may have a slight edge in long-term dependability. The Lexus LC 500 is known for its exceptional reliability.
