BMW i4 Supertest Introduction

The Electric Challenge: i4 vs. Tesla

The BMW i4 eDrive40 Gran Coupe

arrives carrying the weight of expectations. It's more than just another electric vehicle; it represents BMW's attempt to challenge Tesla's dominance in the EV space. However, a significant question looms: can a platform initially designed for combustion engines truly deliver a world-class EV experience?

Chief reporter Alexander Bloch sets out on this supertest with a blend of excitement and scrutiny. While acknowledging the i4's promising specs, he emphasizes the importance of real-world performance and holding it to the highest standards. The underlying architecture, shared with combustion engine vehicles, is a point of contention, demanding a closer look at how BMW has adapted to the electric era.

Testing Methodology: A Rigorous Approach

This isn’t just a casual drive; it's a supertest. This means a strict and standardized approach is used, focusing on repeatable measurements and comparisons. While the "how, what, and why" of each test phase will be detailed in written format on Auto Motor und Sport's website, the video concentrates on the results. The tests will reveal whether the i4 can stand toe to toe with dedicated EV platforms from brands like Tesla.

Efficiency, driving dynamics, and practicality are all put under the microscope. This isn't about brand loyalty; it’s about data-driven assessment. The rating scale, independent of vehicle class, caps at six stars, creating a high bar for excellence. The efficiency hinges on the cars electrical motor setup.

Inside the BMW i4: a Focus on Interior Assessment

Quality and Space: Does the Interior Live Up to the BMW Badge?

Attention is paid to the interior with special care to material, space, and overall fit and finish. BMW usually excels here.

The video highlights a minor paint discrepancy between the plastic front bumper and the metal hood—a detail that might escape casual observation but is flagged due to BMW’s reputation for high quality.

The presenter notes the touch points in the interior: The headliner and the transitions are all seamless and great. He then talks about the trunk and how there is plenty of room for his testing equipment, but it is of note to mention that its a coup style rear to access said equipment and its not a super high space.

Overall, the interior garners positive remarks, particularly the leather trimming and soft-touch materials. The reviewer does mention missing padding. He also notes that the lack of a frunk is a notable space disadvantage when compared to other vehicles.

Navigating Technology: User Interface and Assistance Systems

The BMW i4 is laden with modern tech and the car provides you a multitude of ways to interact with the system. I can chose voice, the touch screen or manual controls.

The layout and user interface are put into question with some of the green app icons lacking contrast and clarity. On the other hand, some aspects that are high praised are the digital dash that provided clear and readable data. the adaptive cruise control also gets praised with is being a life saver on long trips.

Understanding the BMW i4 eDrive40 Pricing Structure

Base Price and Configuration Considerations

The supertest hints at a base price around €60,000,

but emphasizes the need to configure the vehicle to see the final tag. For comparison, here is a price range breakdown:

Model Starting Price (USD)
BMW i4 eDrive40 $56,395
BMW i4 M50 $69,795
Tesla Model 3 Long Range $47,240
Tesla Model 3 Performance $53,240

Keep in mind prices can swing dramatically based on options and customizations!.

Balancing Act: Pros and Cons

👍 Pros

Potentially high efficiency thanks to the ESM motor.

Premium interior quality and refined driving experience.

Practical Gran Coupe body style with a spacious trunk.

Advanced driver-assistance systems for enhanced safety and comfort.

👎 Cons

Shares platform with combustion engine models, leading to possible compromises.

Substantial weight impacting performance and handling.

Charging curve may not be as consistent as some competitors.

Pricing can quickly escalate with options and customizations.

Optimal Use Cases

Who is the BMW i4 eDrive40 For?

While not as nimble in the city as some smaller EVs due to its length, the i4 excels as a comfortable and efficient long-distance cruiser. Ideal for those prioritizing a premium driving experience with a focus on range and a taste of BMW's performance heritage, the i4 finds its sweet spot on the open road.

Here is a table describing what types of drivers the vehicle suits the best:

Driver Profile Ideal Use Cases Not Ideal Use Cases
Commuters (Long Dist) Highway Travel Tight city parking
Small Families Road Trips Off-Roading
Tech-Savvy individuals Efficient driving Hyper-Aggressive driving

The car can excel with those who value style and technology too.

Frequently Asked Questions

Is the BMW i4 built on a dedicated EV platform?
No, the BMW i4 shares its platform with some combustion engine models. This has raised questions about its efficiency and overall design compromises compared to dedicated EV platforms.
What is the real-world range of the BMW i4 eDrive40?
While it can achieve impressive range figures in ideal conditions, expect the real-world range to vary depending on driving style, speed, and weather conditions. Tests are being performed to evaluate its true range capabilities.
How does the BMW i4 compare to Tesla models?
This supertest specifically aims to answer that question! Key areas of comparison include efficiency, charging speeds, interior quality, and driving dynamics.

Dive Deeper: Related Questions & Considerations

What are the key advantages of the electrically excited synchronous motor (ESM) used in the BMW i4?
The electrically excited synchronous motor (ESM) used in the BMW i4 offers a theoretical advantage in efficiency, especially at lower speeds. Traditional electric motors use permanent magnets, which create a constant magnetic field. In an ESM, the magnetic field is generated by an electrical current, allowing for more precise control and potentially reducing energy loss when the motor is not under heavy load. This helps to increase mileage and efficiency in the car.
