BMW is continuing to expand its next generation of electric vehicles, and fresh spy photos have now revealed one of its most anticipated future models. Engineers were recently seen testing the upcoming BMW i4 Convertible, giving enthusiasts an early look at what could become the brand’s first fully electric luxury convertible based on its new Neue Klasse platform.
Although the prototype remains heavily camouflaged, several important design details are already visible. The test vehicle confirms that BMW is preparing a convertible version of its next-generation electric 4 Series, combining a traditional fabric roof with the company’s latest styling language.
The production model is not expected to arrive until the 2029 model year, but these early test vehicles provide valuable clues about BMW’s design direction as it reshapes its electric lineup.
A Familiar Name with an All-New Identity
The upcoming BMW i4 Convertible shares its name with today’s electric i4 Gran Coupe, but the similarities are expected to end there.
BMW is reorganizing its naming strategy as it transitions toward an all-electric future. The next generation of electric models will adopt the company’s Neue Klasse architecture, bringing fresh designs, improved efficiency and more advanced technology.
That means the future i4 Convertible will not simply be an open-roof version of the current i4. Instead, it is expected to become the electric counterpart of BMW’s next-generation 4 Series while sharing much of its engineering with the upcoming electric i3 sedan.
The revised naming approach may take some time for buyers to understand, but BMW appears focused on creating a more unified family of electric vehicles rather than directly replacing existing models.
Soft-Top Roof Returns
One of the most noticeable features visible in the latest prototype is the fabric soft-top roof.
While many luxury convertibles have moved toward retractable hardtops in recent years, BMW appears to be returning to a traditional cloth roof for its future electric convertible.
A soft-top design offers several advantages.
It is generally lighter than a folding metal roof, helping reduce overall vehicle weight while preserving driving range. It also requires less storage space when folded, allowing designers to maintain a cleaner rear profile and maximize luggage capacity.
For an electric vehicle where efficiency remains a priority, every kilogram matters, making the lightweight roof a practical engineering choice.
Neue Klasse Design Takes Shape
Even beneath thick camouflage, the BMW i4 Convertible clearly adopts the styling direction first introduced with BMW’s Neue Klasse concept vehicles.
The front end appears taller and more upright than today’s i4, creating a stronger road presence without relying on oversized styling elements.
The headlights look slimmer and flatter than those found on current BMW models, while the kidney grille appears more vertically oriented. Although the camouflage hides many details, the overall proportions suggest a cleaner and more modern appearance.
BMW has gradually shifted toward simpler body surfaces and sharper character lines across its upcoming electric vehicles, and the convertible follows the same philosophy.
Instead of dramatic creases and aggressive styling, the new design emphasizes clean proportions and aerodynamic efficiency.
More Compact Proportions
Compared with the current 4 Series, the prototype appears slightly shorter from nose to tail while moving the cabin farther forward.
This creates a more balanced profile and may help improve interior packaging despite the vehicle’s sporty proportions.
Short overhangs, a long wheelbase and wider stance also give the prototype a confident appearance even before its final bodywork has been revealed.
At the rear, slim horizontal taillights are visible beneath the camouflage, continuing BMW’s move toward narrower lighting elements across its newest models.
The overall silhouette remains unmistakably that of a premium convertible, blending elegant styling with sporty proportions expected from the BMW brand.
Electric Performance Expected to Mirror the New Generation
BMW has not released official technical specifications for the BMW i4 Convertible, but industry expectations suggest that the convertible will share much of its technology with the next-generation electric i3 sedan.
The new model is expected to ride on BMW’s dedicated Neue Klasse electric platform, which has been developed to deliver greater driving range, faster charging speeds and improved efficiency compared with the company’s current EV architecture.
Although battery sizes and motor outputs remain undisclosed, BMW has already indicated that its future electric vehicles will benefit from more energy-dense battery technology and advanced software designed to optimize performance in real-world driving conditions.
Depending on the variant, buyers can expect both rear-wheel-drive and all-wheel-drive versions, giving customers a choice between efficiency and higher performance.
Performance Variant Could Join the Lineup
BMW’s M division has steadily expanded into the electric vehicle market, making it likely that a more powerful version of the BMW i4 Convertible will eventually follow the standard model.
While BMW has not confirmed an M Performance variant, previous launches suggest the company will offer a sportier model with increased power, sharper suspension tuning and distinctive styling details.
Such a version would appeal to drivers looking for open-top driving without sacrificing the strong acceleration expected from modern electric vehicles.
Instant torque from electric motors has already transformed the driving experience of many performance cars, and BMW will likely continue that approach with its future electric convertible range.
Interior Technology Expected to Advance
The cabin remains hidden from photographers, but BMW’s upcoming electric models provide a strong indication of what buyers can expect.
The BMW i4 Convertible is likely to feature BMW’s next-generation digital cockpit with a cleaner dashboard layout, larger display surfaces and fewer physical controls.
The company has been moving toward software-focused interiors that combine navigation, entertainment and vehicle settings into an integrated digital experience. Voice controls, wireless smartphone connectivity, over-the-air software updates and advanced driver-assistance features are also expected to be part of the package.
Premium materials, supportive seating and improved cabin insulation should help maintain the refinement expected from a luxury convertible, even with the fabric roof.
A Growing Electric Convertible Market
Luxury convertibles remain a niche segment, but manufacturers continue to see demand from buyers who want open-air driving combined with premium comfort and modern technology.
The BMW i4 Convertible would give BMW a stronger presence in the electric convertible market, offering an alternative to traditional petrol-powered luxury drop-tops while supporting the brand’s broader transition toward electrification.
As battery technology continues to improve, electric convertibles are becoming more practical by delivering competitive driving range without compromising performance.
BMW appears determined to ensure that its future electric lineup includes vehicles that appeal not only to commuters but also to enthusiasts looking for an engaging driving experience.
Expected Launch Timeline
Development of the BMW i4 Convertible is still in its early stages, which explains the extensive camouflage covering the prototype.
Additional test vehicles are likely to appear over the next few years as engineers continue refining the design, chassis and electric powertrain before production begins.
Current expectations point to a 2029 model-year launch, with an electric coupe expected to arrive alongside the convertible.
BMW will likely reveal more technical details closer to production, including battery options, driving range, charging capabilities and performance figures.
BMW Keeps Technical Details Under Wraps
BMW has not confirmed technical specifications or an official reveal date for the BMW i4 Convertible, leaving questions about battery capacity, driving range, charging speeds and performance unanswered for now. Those details are likely to emerge as development moves closer to production.
The latest prototype, however, confirms that BMW is moving ahead with an electric successor to the 4 Series Convertible. Future test vehicles are expected to reveal more of the production design as camouflage is gradually removed ahead of the model’s anticipated arrival for the 2029 model year.
This style mirrors how established automotive news outlets conclude spy-shot stories: it stays focused on verified information, avoids unnecessary speculation, and ends by pointing readers toward what comes next in the vehicle’s development.
