Quick Answer: The BMW X3 vs BMW iX3 comparison shows that San Diego drivers could save around $1,647 a year by switching to electric driving. At 12,000 miles annually and $6.50 per gallon, a 2026 BMW X3 xDrive30 would cost approximately $2,690 in gasoline, while charging a 2027 BMW iX3 50 xDrive could cost about $1,043 at an assumed electricity rate of 27.2 cents per kWh. Your actual savings will depend on how much you drive and when you charge.

For San Diego drivers, the difference can add up over time, especially if you can charge at home during lower-priced hours.

How Much Would You Spend on Gas for a BMW X3 in San Diego?

Driving a 2026 BMW X3 xDrive30 for 12,000 miles would cost around $2,690 a year in gasoline at $6.50 per gallon. The EPA estimates this model gets 29 MPG combined, which means you’d use roughly 414 gallons annually and spend about $224 a month.

If you regularly commute between El Cajon and downtown San Diego, your actual expenses will depend on how far you drive and how much time you spend in traffic. The $6.50 gasoline price is an estimate for this comparison, so your costs could be higher or lower depending on local prices.

BMW X3 vs BMW iX3: How Much Could You Save on Energy?

Switching to the electric BMW iX3 could save you around $1,647 a year under the assumptions used in this comparison. The 2027 iX3 50 xDrive uses an EPA-estimated 32 kWh of electricity per 100 miles with 21-inch all-season tires. Over 12,000 miles, that works out to about 3,840 kWh of electricity.

At an estimated electricity rate of 27.2 cents per kWh, you’d spend approximately $1,045 annually charging the iX3, compared with $2,690 on gasoline for the X3. That’s roughly 61% less in driving energy costs.

Of course, your electricity bill will depend on your plan and when you charge. These estimates also leave out other ownership expenses, such as insurance, maintenance, and the cost of installing a home charger.

How Much Does It Cost to Charge a BMW iX3 in San Diego?

When you charge matters more than almost anything else. SDG&E’s EV-TOU-5 rates effective August 1, 2026, list winter prices of 12.3 cents per kWh super off-peak, 46.6 cents off-peak, and 52.4 cents on-peak for customers who buy their electricity from SDG&E.

At 12,000 miles a year, charging entirely at 12.3 cents would cost about $472, while charging at 46.6 cents would cost about $1,789. Even charging only on-peak would cost about $2,012, still less than the X3’s $2,690 in gas.

If you get home from work in Mission Valley around 6 p.m., scheduling the iX3 to charge after midnight keeps you out of the 4 to 9 p.m. on-peak window. SDG&E plans also include a daily base charge, and community choice aggregator customers may pay different rates, so compare your options through SDG&E’s residential electricity plans.

Will Public Charging Make the BMW iX3 More Expensive to Drive?

Public charging usually costs more than charging at home overnight, and prices vary by station, sometimes with session or parking fees. At an assumed 60 cents per kWh, driving 100 miles in the iX3 would cost about $19.20, compared with $22.41 in the X3 at $6.50 per gallon.

The iX3 can charge at up to 400 kW at compatible DC fast chargers, adding about 185 miles in 10 minutes under ideal conditions. If most of your charging happens at home, occasional public charging won’t change your annual costs much.

Is the BMW iX3 Worth the Higher Purchase Price?

The iX3 could save you money on electricity over time, but it’s worth looking at the purchase price before deciding. BMW announced a starting MSRP of $61,500 for the 2027 iX3 50 xDrive, excluding destination charges, while the 2026 X3 xDrive30 starts lower.

If the electric model costs $8,000 more in the configurations you’re considering, saving approximately $1,647 a year on energy would take nearly five years to make up that difference. That’s a simplified example, since financing, depreciation, maintenance, and other expenses can also affect the total cost of ownership.

Your plans matter here. If you expect to keep your BMW for several years and have affordable home charging, those savings could matter more. If you’re considering a shorter lease or don’t have easy access to charging, the gasoline X3 may be worth a closer look. You can also explore our 2027 BMW iX3 pricing guide for more details.
