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

The BMW i4 is the cheaper of the two — it starts at $88,900 versus $142,900 for the BMW iX, a $54,000 difference. Prices shown are manufacturer recommended retail excluding on-road costs.

Which has the longer driving range?

The BMW iX has the longer WLTP-claimed range at 602 km, 154 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 iX accepts a peak DC charging rate of 200 kW versus 180 kW for the BMW i4. Peak rate only holds for a short window during the charging curve, so real-world 10–80% times often diverge less than the peak numbers suggest. 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 iX does 0–100 km/h in 5.1 seconds — 0.7 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 iX?

On paper the BMW i4 is $54,000 cheaper, but trails the BMW iX 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 iX is the spec-sheet winner.

Head-to-head

BMW i4 vs BMW iX

At $88,900 the BMW i4 undercuts the BMW iX by $54,000 (38%) — but does the premium deliver enough of an edge to justify itself? Here's how the two compare on price, range, charging, safety and warranty.

Option A · Sedan

BMW i4

BMW's electric Gran Coupe — a four-door fastback that effectively replaces the petrol 4 Series Gran Coupe for many buyers. The 4-star ANCAP rating is unusual at the price; everything else delivers the expected BMW driving experience.

From: $88,900
Range: 448 km
Battery: 66.4 kWh

Option B · SUV

BMW iX

BMW's electric flagship SUV — a polarising design with a cavernous, well-resolved cabin. Large 94.8 kWh battery, 602 km WLTP range, and one of the more pleasant premium EVs to drive.

From: $142,900
Range: 602 km
Battery: 94.8 kWh
