Which is cheaper, the BMW i4 or the BMW iX3?

The BMW i4 is the cheaper of the two — it starts at $88,900 versus $109,900 for the BMW iX3, a $21,000 difference. Prices shown are manufacturer recommended retail excluding on-road costs.

Which has the longer driving range?

The BMW iX3 has the longer WLTP-claimed range at 805 km, 357 km further than the BMW i4's 448 km. Real-world range typically lands 10–20% below the WLTP figure depending on speed, terrain, climate and load.

Which one charges faster on a DC fast charger?

The BMW iX3 accepts a peak DC charging rate of 400 kW versus 180 kW for the BMW i4.

Compatibility with 350 kW chargers depends on the vehicle's onboard architecture, not just the published peak.

Which is quicker off the line?

The BMW iX3 does 0–100 km/h in 4.9 seconds — 0.9 s quicker than the BMW i4's 5.8 s. EV acceleration figures hold up at speed better than equivalent petrol cars because electric motors deliver peak torque instantly.

Is the BMW i4 better value than the BMW iX3?

On paper the BMW i4 is $21,000 cheaper, but trails the BMW iX3 on the core measurable specs. The saving might still be worth it if you don't need the extra range, power or charging speed — but the BMW iX3 is the spec-sheet winner.
