BMW iX4 vs BMW iX3 is a comparison BMW itself created by building two electric SUVs on the same platform with nearly identical performance. The iX4 just launched at $67,695, a $4,845 premium over the iX3’s $62,850. Here’s what that premium actually buys, beyond just a different roofline.

Power And Range: Nearly Identical, With One Surprise
Both the iX3 50 xDrive and iX4 50 xDrive produce the same 463 horsepower and share the same 112-kWh-class battery. Performance figures are effectively a wash between them, with both quoting a 4.7-second run to 60 mph.
Range is where it gets genuinely surprising: the iX3 is rated for 434 miles, six miles more than the iX4’s 428-mile estimate, despite the iX4 costing nearly $5,000 more. A sportier roofline typically costs some efficiency, and that pattern holds here too.
What The iX4 Premium Actually Covers
Standard M Sport equipment on the iX4 represents a $2,500 value if added separately to an iX3, meaning the true styling-and-shape premium is closer to $2,345 once that’s accounted for. That’s a more reasonable gap than the headline $4,845 figure suggests.
Both share identical 800-volt architecture and 400 kW peak DC charging, so charging speed is not a differentiator between them. Whatever a buyer is actually paying for comes down entirely to shape and standard trim level.
Technician’s Note: Configure an equivalent iX3 with the M Sport package added before comparing total cost directly against a base iX4. A straight MSRP-to-MSRP comparison overstates the iX4’s actual premium once equivalent equipment is factored in.
Cargo Space: The iX3’s Clearest Advantage
BMW hasn’t published exact iX4 cargo figures yet, but every prior Sports Activity Coupe BMW has built trades cargo volume for its sloped roofline. A buyer prioritizing maximum interior utility over styling has a clear, practical reason to choose the iX3 instead.
Which One Actually Fits A Buyer
A buyer prioritizing maximum range, cargo space, and the lowest possible price should choose the iX3. A buyer who specifically wants the coupe-SUV silhouette and was already planning to add M Sport should lean iX4, where the real-world price gap shrinks considerably.
Common Questions About The BMW iX4 And iX3
Is the BMW iX4 faster than the iX3?
No. Both the iX3 50 xDrive and iX4 50 xDrive share the same 463 horsepower powertrain and an identical 4.7-second 0-60 mph estimate. Performance is not a differentiator between the two models at this trim level.
Why does the cheaper iX3 have more range than the iX4?
The iX4’s sloped, coupe-like roofline reduces aerodynamic efficiency slightly compared to the iX3’s more upright shape, a tradeoff common across every Sports Activity Coupe BMW has built, electric or otherwise.
Does the iX4’s higher price include extra standard equipment?
Yes. The iX4 comes standard with the M Sport package, which costs $2,500 as an add-on to the iX3, meaning the true shape-and-styling premium is smaller than the full MSRP gap between the two models.
