In Edmunds testing, the iX3 outlasted every other luxury electric SUV at 436 miles

BMW’s new iX3 drove 436 miles on a single charge in Edmunds testing, 44 miles beyond its 392-mile EPA rating. That makes the SUV the longest-range luxury electric SUV Edmunds has measured, ahead of every rival the outlet has put through the same procedure. The result arrived on Nov. 6.

Range tests that beat the sticker are uncommon enough to be news on their own, because most electric vehicles land at or below the EPA estimate once real roads and weather are involved. The iX3 50 xDrive in this case also used less energy than the government figure implies, which is what stretched the distance past 400 miles. Edmunds tested the version on 22-inch tires, a wheel size that normally costs range.

Edmunds numbers for the iX3 against its EPA rating

Edmunds measured 28.3 kWh per 100 miles, against the 32 kWh the EPA estimate implies, an efficiency edge of roughly 11 percent. Electrek’s account of the run, published Nov. 6, describes a loop of about 60 percent city and 40 percent highway driving at an average of 40 mph, staying within 5 mph of posted limits with climate control on auto at 72 degrees. Edmunds says the result sets a new benchmark for luxury electric SUVs; the write-up is credited to Angel Sergeev and edited by Steven Ewing.

The EPA rating itself is public through the federal fueleconomy.gov EV comparison tool, which is where the 392-mile figure for this configuration can be checked. The EPA also lists the 32 kWh per 100 miles consumption used for comparison, and the Edmunds number of 28.3 beats it by about 3.7 kWh over every 100 miles driven, an advantage that compounds across a 108.7 kWh pack into the extra 44 miles.

Edmunds publishes these numbers from its own EV Range Test, a standardized loop it runs on every electric vehicle so results can be compared across brands. Because the loop is the same for each car, the 436-mile result can be set directly against the other SUVs the outlet has driven, and Edmunds says the iX3 now tops that list. The gap between measured and rated range, 44 miles or about 11 percent, is also unusually large for a modern electric vehicle.

Rival luxury electric SUVs in the same test

The gap to the field is wide. The Mercedes-Benz GLC Electric reached 392 miles in Edmunds testing, matching the BMW’s EPA number but 44 miles short of its measured result. The Volvo EX60 managed 352 miles, which Electrek reported in October, and the Porsche Macan 4 Electric landed at the same 352. The Audi Q6 e-tron finished at 337 miles. Energy use tracked the same order: the GLC Electric used 28.4 kWh per 100 miles and the EX60 used 28.8, against the iX3’s 28.3.

Battery size, charging and what the iX3 costs

A large pack explains much of the lead. The iX3 carries a 108.7 kWh battery and accepts up to 400 kW DC fast charging, which BMW rates at roughly 10 to 80 percent in about 21 minutes, or about 185 miles of range added in 10 minutes. Starting prices run $61,500 for the Sport, $64,000 for the M Sport and $65,500 for the M Sport Professional, before a $1,350 destination fee.

Context matters for shoppers deciding how much range is enough. A BMW Group survey found Americans want more range than they need day to day, a finding published in BMW’s U.S. newsroom and echoed in an Electrek report on range expectations, where most respondents said 75 miles or less covers a typical day. Against that backdrop, 436 miles is a margin few drivers will use daily, and the practical value shows up on road trips.

Buyers should also keep trims in mind. Edmunds tested the 50 xDrive, and the EPA rating of 392 miles belongs to that configuration. Other iX3 versions, wheel sizes and tire choices will rate differently, and BMW’s own range claims for the model vary by market because European and American test cycles are not the same. Shoppers comparing the iX3 with the Mercedes, Volvo or Porsche should match trim and wheel size before treating any single figure as the car’s range.

One caution applies to any single-charge test. Edmunds ran a mixed city and highway loop at moderate speeds, and results at sustained 75 mph or in winter cold would be lower. The 436-mile figure is a measured outcome for one car on one route, and the rankings above compare it with other cars Edmunds drove on its standard procedure. Anyone cross-shopping should treat the 44-mile margin as evidence the EPA label is conservative for this model, not as a guarantee for every owner.
