BMW i4: A Comprehensive Guide

The BMW i4 represents BMW's foray into the premium electric Gran Coupe segment. It blends the practicality of a four-door hatchback with the sporty driving dynamics BMW is known for. Introduced in 2021 as a 2022 model, the i4 is a pivotal vehicle in BMW's electrification strategy, aiming to offer a compelling alternative to gasoline-powered cars without sacrificing the brand's performance and luxury characteristics. It competes primarily with the Tesla Model 3 and Polestar 2.

Generations

G26 (2022-Present)

The G26 generation is the first and, currently, only generation of the BMW i4. Key features and changes since its inception include:

  • 2022 Launch: Initial models included the i4 eDrive40 and i4 M50. The eDrive40 is a rear-wheel-drive model, while the M50 boasts all-wheel drive and significantly higher performance.
  • Battery Technology: Utilizes BMW's fifth-generation eDrive technology, featuring high-voltage batteries with impressive energy density and charging capabilities.
  • Curved Display: Introduced BMW's curved display, integrating a 12.3-inch information display and a 14.9-inch control display into a single, driver-focused unit.
  • Software Updates: The i4 receives regular over-the-air software updates, enhancing functionality and adding new features.
  • 2024 Model Year Updates: Minor cosmetic changes, including new exterior paint options and interior trim updates. Improvements to charging speeds and efficiency have also been rolled out via software updates. A new entry-level i4 xDrive40 model with all-wheel drive was also introduced.

Reliability & Common Issues

As a relatively new model, long-term reliability data for the i4 is still emerging. However, based on initial reports and comparisons to other BMW EVs, here's a breakdown of potential areas of concern:

Battery and Powertrain

  • High-Voltage Battery Degradation: Like all EVs, the i4's battery will experience gradual degradation over time. BMW offers a battery warranty (typically 8 years or 100,000 miles) to cover excessive degradation. Keeping the battery between 20%-80% charge when not needed and avoiding frequent DC fast charging will extend battery life.
  • Charging System Issues: Some owners have reported occasional problems with the charging system, including slow charging speeds or failures to initiate charging. These issues are often resolved through software updates or hardware replacements under warranty. Ensure the charging infrastructure you use is reliable and well-maintained.
  • Electric Motor Reliability: BMW's electric motors have generally proven to be reliable in their other EV offerings, and the i4 is expected to follow suit. However, potential issues could arise with the power electronics or cooling systems.

Electronics and Software

  • Software Glitches: The i4's complex infotainment system and driver-assistance features can be prone to software glitches. These can range from minor annoyances to more serious issues affecting vehicle functionality. Regular software updates are crucial for addressing these problems.
  • Connectivity Issues: Problems with Bluetooth connectivity, Apple CarPlay/Android Auto integration, and BMW ConnectedDrive services have been reported by some owners.
  • Sensor Malfunctions: The i4 relies on a network of sensors for its driver-assistance systems. Malfunctions of these sensors (e.g., radar, cameras) can lead to errors and potentially compromise safety features.

Other Potential Issues

  • Suspension and Steering: Like other BMWs, the i4's suspension and steering components could be subject to wear and tear over time, particularly if driven on rough roads. Pay attention to any unusual noises or vibrations.
  • Brake System: The regenerative braking system helps to reduce wear on the traditional brake pads and rotors. However, it's still essential to inspect the brakes periodically for proper function.
  • Interior Quality: While the i4's interior is generally well-appointed, some owners have noted minor issues with trim pieces and upholstery.

Driving Experience

The BMW i4 provides a compelling blend of performance, comfort, and technology, making it a desirable electric vehicle for many drivers.

Pros:

  • Performance: The i4 offers brisk acceleration, particularly in the M50 variant. The instant torque from the electric motors provides a thrilling driving experience.
  • Handling: BMW's engineering shines through in the i4's handling characteristics. The car feels planted and responsive, offering a sporty and engaging driving experience.
  • Comfort: The i4 provides a comfortable and refined ride, with well-designed seats and a quiet cabin.
  • Technology: The curved display and iDrive 8 system offer a modern and intuitive user experience. The driver-assistance features enhance safety and convenience.
  • Practicality: As a Gran Coupe, the i4 offers ample space for passengers and cargo. The hatchback design provides easy access to the rear cargo area.

Cons:

  • Range: While the i4's range is competitive, it may not be sufficient for all drivers, particularly those who frequently take long trips. Consider your driving habits and charging infrastructure availability.
  • Charging Time: DC fast charging is supported, but charging times can still be longer than filling up a gasoline car.
  • Price: The i4 is a premium electric vehicle and comes with a higher price tag than some of its competitors.
  • Firm Ride (M50): The M50 model's sport-tuned suspension can result in a firmer ride, which may not be ideal for those prioritizing comfort.
  • Artificial Sound: The artificial "IconicSounds Electric" sound designed by Hans Zimmer can be polarizing. Some drivers may find it distracting or unnecessary.

Buying Advice

If you're considering purchasing a BMW i4, here's some advice to help you make an informed decision:

Years to Look For:

  • 2023 and Newer: Models from 2023 onwards benefit from minor improvements and refinements compared to the initial 2022 models. They often include software updates and potentially better availability of certain features. The 2024 models introduced the xDrive40 which might be a worthwhile feature for certain climates.

What to Avoid:

  • Early Production 2022 Models: While not necessarily bad, very early production 2022 models might be more prone to initial software glitches or manufacturing quirks. Check the vehicle's history and service records carefully.
  • Vehicles with Extensive Damage History: Avoid vehicles with significant accident damage or a salvage title. The complex electrical system can be particularly vulnerable to damage.
  • Overpriced Models: Research the market value of similar i4 models in your area to ensure you're not overpaying. Consider factors such as mileage, condition, and optional equipment.

Pre-Purchase Inspection:

  • Battery Health: Have a qualified technician check the battery health and capacity. Look for any signs of excessive degradation.
  • Charging System: Test the charging system with both AC and DC chargers to ensure proper functionality.
  • Software and Electronics: Verify that the software is up-to-date and that all electronic features are working correctly.
  • Suspension and Brakes: Inspect the suspension and brakes for any signs of wear or damage.

Consider Your Needs:

  • Driving Range: Evaluate your daily driving needs and charging infrastructure availability to determine if the i4's range is sufficient.
  • Performance Requirements: Decide whether you need the extra performance of the M50 model or if the eDrive40 provides adequate power.
  • Budget: Establish a budget and compare the i4's price to other electric vehicles in its class.
  • Test Drive: Take the i4 for an extended test drive to experience its driving dynamics, comfort, and technology firsthand.
