The 2023 BMW 4 Series continues BMW's legacy of sporty coupes and convertibles, spun off from the 3 Series line. Available as a coupe, convertible, or Gran Coupe (a four-door hatchback), the 4 Series offers distinctive styling. Key trims include the 430i, M440i, and the high-performance M4. Pricing ranges from approximately $48,000 to upwards of $75,000, depending on trim and options. Its blend of performance, luxury, and bold design makes it a popular choice among driving enthusiasts.
The Good

The 2023 BMW 4 Series boasts a potent blend of performance and style. Its powerful engine options provide thrilling acceleration, appealing to emotional buyers. Practical buyers appreciate its comfortable interior, advanced technology, decent fuel efficiency (depending on the engine), and the BMW badge, representing a level of reliability and prestige. Design-wise, it’s striking and sets it apart from competitors.

The Bad

The 2023 BMW 4 Series, despite its strengths, has some weaknesses. The polarizing front grille design is a point of contention for many. Some reviewers find the ride quality to be firm, especially with the M Sport suspension. Also, the rear seat space, particularly in the coupe, is limited. Be mindful of potential maintenance costs associated with BMW ownership and check for infotainment glitches.

Analysis

What Problems Does the 2023 BMW 4 Series Have?

While the 2023 BMW 4 Series is generally reliable, some frequently reported problems include issues with the infotainment system (freezing, glitches, connectivity problems), particularly with wireless Apple CarPlay and Android Auto. Some owners have reported minor electrical issues, such as sensor malfunctions or issues with the ambient lighting. Engine oil leaks, although not widespread, can occur in some BMW engines over time, so it's important to monitor oil levels and perform regular maintenance.
Recalls can vary, so checking the NHTSA (National Highway Traffic Safety Administration) website for the latest recall information specific to the 2023 model year is crucial. Long-term reliability concerns generally center around the complexity of modern BMWs. The numerous electronic systems and sensors can potentially lead to higher repair costs as the vehicle ages. Regular maintenance, using quality parts, and addressing issues promptly can help mitigate these concerns. There are no widespread, model-year-specific major reliability issues reported yet, but it's still a relatively new vehicle. It's advisable to monitor owner forums and reviews for any emerging patterns over the next few years.

How long will the 2023 BMW 4 Series last?

With proper maintenance, the 2023 BMW 4 Series can realistically provide 150,000 to 200,000 miles or 10-15 years of service. This depends heavily on consistent maintenance, adherence to service schedules, and driving habits.
Long-term durability hinges on addressing potential issues early. Weaknesses can emerge in the form of electronic component failures, suspension wear (especially with sportier trims), and potential issues with the cooling system. Keeping up with fluid changes (oil, coolant, transmission fluid) and proactive maintenance can significantly extend the vehicle's lifespan.

What Technology & Safety Features are Included?

The 2023 BMW 4 Series is equipped with a comprehensive suite of technology and safety features.
Built-in Tech & Entertainment: It features the iDrive infotainment system with an 8.8-inch touchscreen (upgradable to a larger 10.25-inch display), Apple CarPlay and Android Auto compatibility, navigation, Bluetooth connectivity, and a premium sound system. Optional features include a Harman Kardon surround sound system, a head-up display, and wireless device charging.
Driver-Assistance Features: Standard safety features include lane departure warning, forward collision warning with automatic emergency braking, and pedestrian detection. Optional driver-assistance systems include adaptive cruise control, lane keeping assist, blind spot monitoring, rear cross-traffic alert, and parking assistant plus.
Safety Features: Standard features include multiple airbags, anti-lock brakes, stability control, and a rearview camera.
Crash-Test Ratings: The 2023 BMW 4 Series has not been fully evaluated by both NHTSA and IIHS. As of the last update, the IIHS (Insurance Institute for Highway Safety) gave the 2023 4 Series coupe a 'Good' rating in several crash tests, but full results may vary depending on the body style and specific tests. Check the IIHS and NHTSA websites for the most up-to-date crash-test ratings.

2023 BMW 4 Series Prices and Market Value

The 2023 BMW 4 Series had a starting MSRP of around $48,000 for the 430i and upwards of $59,000 for the M440i, with the M4 starting significantly higher. Current used market prices vary depending on mileage, condition, and trim. Expect to find 2023 models priced anywhere from the low $40,000s to the mid $60,000s.
Depreciation is typical for a luxury vehicle. Factors affecting resale value include mileage, condition, service history, and whether it’s a popular configuration (color, options). M models tend to hold their value better than base models. Low mileage and a clean Carfax report significantly boost resale value.

2023 BMW 4 Series Cost of Ownership

The 2023 BMW 4 Series is generally considered costly to own. Insurance premiums are higher than average due to the vehicle's performance and value. Fuel costs vary depending on the engine; the 430i is more economical than the M440i or M4. Maintenance and repair costs are also above average, as BMW parts and labor tend to be expensive. Long-term ownership requires budgeting for potential repairs, especially as the car ages. Proper maintenance can mitigate some costs but overall, it's not an economical choice.

How Does the 2023 BMW 4 Series Compare to Other Convertible?

The 2023 BMW 4 Series competes with the Audi A5/S5, Mercedes-Benz C-Class Coupe/Convertible, Lexus RC, and Infiniti Q60.
Performance: The 4 Series excels in driving dynamics, often praised for its sharp handling and powerful engines, rivaling the A5/S5 and C-Class. The M4 is a true performance benchmark.
Features: The 4 Series offers a comparable range of tech and luxury features to its German competitors, with a user-friendly iDrive system.
Reliability: The Lexus RC typically enjoys a stronger reputation for long-term reliability than the 4 Series, while the other competitors are generally similar.

The Audi S5 offers a similar blend of performance and luxury, and the Mercedes-Benz C-Class provides a more comfortable and luxurious experience. Ultimately, the best choice depends on individual priorities and preferences. Test driving each model is highly recommended.

Final Verdict: Is the 2023 BMW 4 Series a Good Convertible?

The 2023 BMW 4 Series is ideal for driving enthusiasts who appreciate a blend of performance, style, and technology. It's worth buying if you prioritize driving dynamics and are willing to accept the potential for higher ownership costs.
Whether to buy new or used depends on budget and preferences. A used model offers potential savings, but a thorough inspection is crucial. The M440i trim provides a sweet spot between performance and daily drivability. If you want the ultimate performance experience, the M4 is the clear choice. However, be mindful of the firm ride and higher running costs. Consider your priorities and budget to make an informed decision.
