Electric SUVs like the BMW iX generate their heat differently from combustion cars, but they still need effective brake cooling -- and heavy factory wheels with poor airflow do not help.
Reducing unsprung mass is one of the few modifications that improves an EV in every measurable way: range, handling, ride comfort, and brake wear. Factory wheels on the BMW iX weigh approximately 14-15 kg each. The Bete Noire Ver1.7, machined from a single 6061-T6 forged aluminium billet, cuts that to under 10.5 kg. Across four corners, you remove roughly 15-18 kg of rotating mass. The motors work less hard to accelerate and decelerate the wheels, the suspension responds faster to road imperfections, and the brakes -- both regenerative and friction -- operate more efficiently. Our forged vs flow-formed vs cast wheels guide explains the engineering in detail.
The Bete Noire Ver1.7 features six pairs of parallel spokes with aero-blade profiles, designed to channel air toward the brakes. The paired arrangement creates visual rhythm while the aero-blade cross-section adds a functional element -- directing airflow to cool the brakes under sustained motorway driving. In matte black it suits the BMW iX's factory lines particularly well, though every wheel in Hodoor's AI programme is available in any finish you specify.

The Bete Noire Ver1.7 is part of Hodoor's AI wheel design programme. The system generates over 1,000 unique wheel concepts per day, each one engineered to be manufacturable as a forged monoblock. You are not choosing from a static catalogue -- the AI produces designs tuned to a specific car's dimensions, brake clearances, and visual character. The design phase is free. You only pay when a concept moves into production.
If none of the AI-generated options suit, our in-house designer can work from hand sketches or reference images. Either route leads to the same CNC-machined 6061-T6 billet, the same balancing and inspection process, and the same four-to-eight-week production timeline.
How much range can I gain with lighter wheels on the BMW iX?
Real-world testing on EVs shows that reducing unsprung mass by 15-20 kg across four wheels can improve range by 2-4% depending on driving conditions. On the BMW iX's ~600 km WLTP, that translates to roughly 10-20 km of additional range per charge. More detail in our performance wheels guide.
Will the regenerative braking system work normally with aftermarket wheels?
Yes. Regenerative braking is managed by the electric motors, not the wheels. The Bete Noire Ver1.7 design does not interfere with any sensor rings or ABS components. The bolt pattern (5x112), centre bore (66.5 mm), and offset are matched to factory specifications.
Are forged wheels safe for the BMW iX's weight?
The BMW iX is a heavy vehicle, and forged 6061-T6 aluminium is the strongest wheel material available in the aftermarket. The grain structure of forged billets handles high load ratings significantly better than cast alternatives. Contact us for load-rated specifications.
