Bmw’s new IX3 is an efficiency beast

Energy efficiency is crucial for electric vehicles, and Tesla's Model Y has long dominated this area. However, the upcoming 2026 BMW iX3 might soon dethrone it. Built on the new Neue Klasse platform, the iX3 achieves an impressive consumption of just 15 kWh/100 km (4.14 miles/kWh), according to BMW CEO Oliver Zipse. This is a remarkable performance for a dual-motor SUV equipped with a battery exceeding 100 kWh and weighing approximately 2,270 kg.
By comparison, the previous rear-wheel-drive iX3 with a 74 kWh battery consumed 18.9 kWh/100 km. BMW's advances are attributed to new cylindrical cells with 20% higher energy density and the integration of sixth-generation powertrains using silicon carbide—more expensive, yet more efficient.
The refreshed Tesla Model Y (AWD, long-range) records a WLTP consumption of 15.3 kWh/100 km, slightly higher than the new iX3. As for range, BMW claims up to 800 km, compared to 622 km for the Model Y.
Despite these impressive figures, the iX3 might struggle to attract Tesla customers, as its expected price is nearly double that of an equivalent Model Y.
