The transition of the BMW Vision iNext from a concept car to the production model, the BMW iX, was a
remarkable exercise in engineering and design, preserving the essence of the original vision while adapting
it for the real world. Launched globally in 2021, the iX materialized the promises of technology,
sustainability, and a new kind of luxury.
Translation of the Exterior Design
The iX was conceived to redefine the concept of the Sports Activity Vehicle (SAV), BMW's term for its
SUVs. Its proportions are a calculated fusion of other models in the X lineup: it has a length and width
comparable to the BMW X5, the roof height of a BMW X6, and the imposing wheel size (up to 22 inches) of a
BMW X7.
The most discussed and controversial design element is, without a doubt, the large vertical front grille.
However, its shape is not merely a stylistic choice, but a direct consequence of the vehicle's
electrification. Since the electric propulsion system requires significantly less air cooling compared to a
combustion engine, the traditional function of the grille became obsolete. BMW, therefore, reinvented it as
an "intelligence panel". Behind its transparent surface, the grille houses a range of essential technologies
for the semi-autonomous driving systems, including cameras, radar, and other sensors. To ensure these
sensors remain fully functional at all times, the surface of the grille is coated with a polyurethane layer
that features a "self-healing" capability. Minor scratches and chips disappear over time or with the
application of heat, ensuring the car's "vision" is never obstructed. Thus, the design of the grille is a
physical expression of BMW's transition from a mechanical era to a digital and electric era, where form
follows the new function.
Aerodynamic efficiency was a top priority in the development of the iX. With a drag coefficient (Cd) of just
0.25, the iX became the most aerodynamic SUV ever built by BMW. This feat was achieved through a clean
surface design, flush door handles, frameless windows, and aerodynamic wheels. The low air resistance is not
just a technical achievement; it has a direct and significant impact on the vehicle's range, adding about 65
km in the WLTP test cycle.
Construction and Materials – The "Carbon Cage"
The foundation of the iX is an entirely new electric drivetrain architecture, yet designed to be
highly compatible with BMW's modular CLAR platform. This compatibility is a crucial strategic decision.
Instead of investing in factories dedicated exclusively to electric vehicles, BMW opted for a flexible
manufacturing approach. This allows the iX to be produced on the same assembly line as combustion cars at
the Dingolfing plant in Germany. This strategy offers resilience, allowing the company to adjust production
based on market demand and make a more gradual transition to electrification, mitigating financial risks.
The structure of the iX is an example of advanced materials engineering. It utilizes an aluminum spaceframe
combined with what BMW calls the "Carbon Cage", an evolution of the "Carbon Core" seen in
the 7 Series. Carbon Fiber Reinforced Plastic (CFRP) is used extensively in critical areas like the side
frame, roof, and rear window opening to increase rigidity and reduce weight. The rest of the body is a mix
of high-strength steel, aluminum, and thermoplastics, optimizing safety and efficiency.
The Minimalist and Sustainable Interior
Inside the iX, the "Shy Tech" philosophy of the Vision iNext is evident. The design is minimalist and
human-centric, with a reduced number of physical buttons. The focal point of the dashboard is the impressive
BMW Curved Display, a single curved piece of glass that floats above the dashboard and
unites a 12.3-inch digital instrument cluster with a 14.9-inch infotainment screen. The iX was the first BMW
model to debut this display alongside the iDrive 8 operating system, which offers
customizable graphics and an enhanced voice assistant.
Another distinctive design element is the hexagonal steering wheel, a functional choice designed to improve
visibility of the instrument panel and facilitate entry and exit from the vehicle. Luxury in the iX is
defined as much by technology as by sustainability. Materials include FSC-certified open-pore wood trims,
"Crafted Clarity" glass controls for the gear selector and iDrive controller, and upholstery options ranging
from leather tanned with olive leaf extract to a sustainable fabric called "Loft," which uses microfiber.
One of the most innovative features is the panoramic "Sky Lounge" roof. Instead of a
physical sunshade, it uses Polymer Dispersed Liquid Crystal (PDLC) technology. At the touch of a button, an
electrical current is applied to a film layer within the glass, causing the liquid crystals to align and the
roof to become transparent. When the current is turned off, the crystals scatter and the glass becomes
opaque, providing shade and privacy. This is a unique feature in the automotive industry and a perfect
example of the "Shy Tech" philosophy in action.
