The BMW i4 is BMW's answer to an all-electric 3 Series
BMW stopped making a gas-powered 3 Series sedan and replaced it with the i4, an all-electric four-door that seats five and delivers the handling BMW owners expect. The i4 comes in two versions: the eDrive40 with one motor (335 horsepower) and the M440i xDrive with dual motors (536 horsepower). Both use the same battery pack, which stores 81.5 kilowatt-hours of usable energy and delivers an EPA-estimated range of 260 to 301 miles per charge, depending on which model you choose and how you drive.
If you're coming from a gas 3 Series or comparing the i4 to other electric sedans in its price range, the key trade-off is straightforward: you get the BMW driving feel and interior quality you know, but you lose the option to refuel in five minutes and you'll need to plan around charging time on long trips. The i4 starts around $60,000 before incentives, which puts it above a base Tesla Model 3 but below a Lucid Air.
Key Takeaways
- The i4 comes in two powertrains: a single-motor eDrive40 with 335 horsepower and a dual-motor M440i xDrive with 536 horsepower, both using the same 81.5-kWh battery.
- EPA range runs from 260 miles on the M440i to 301 miles on the eDrive40, meaning the heavier performance model loses range despite identical battery capacity.
- Charging at home on a Level 2 charger (240 volts) takes roughly 10 hours for a full charge; DC fast charging at a public station adds 200 miles in about 35 minutes.
- The i4 qualifies for up to $7,500 in federal tax credit if you buy it new, though BMW models are subject to price caps and assembly-location rules that change yearly.
- Real-world efficiency varies between 3.5 and 4.5 miles per kilowatt-hour depending on driving style, weather, and whether you use the heat or air conditioning.
How the two i4 powertrains compare
The eDrive40 uses a single rear motor and front-wheel-biased weight distribution. It accelerates from 0 to 60 mph in 5.5 seconds and delivers 260 miles of EPA range. This is the model most buyers choose because it costs less, uses less energy per mile, and still feels quick in everyday driving. The trade-off is that it has no all-wheel drive, so in snow or ice you'll feel the rear end move around more than you would in the dual-motor version.
The M440i xDrive adds a second motor at the front, giving you all-wheel drive and 536 horsepower. It hits 60 mph in 3.9 seconds and handles like a sports sedan. The catch: it weighs more, uses more energy, and EPA range drops to 260 miles—the same as the single-motor car. If you live somewhere with winter weather or want the performance, the M440i makes sense. If you're chasing range or lowest cost, the eDrive40 is the better math.
Both versions use the same 81.5-kWh battery and both can accept DC fast charging at up to 200 kilowatts. Both also come with BMW's iDrive 8 infotainment system, a 14-inch touchscreen, and wireless Apple CarPlay and Android Auto. The M440i adds adaptive suspension and a sportier interior trim.
Real-world charging times and what to expect at home
Charging speed depends on three things: the charger you use, the car's onboard charger, and the battery's state of charge. At home on a Level 2 charger (240 volts, 11.5 kilowatts), a full charge takes roughly 7 to 10 hours. Most owners plug in overnight and wake up to a full battery. If you only have 120-volt household current, expect 40+ hours for a full charge—this is too slow for regular use and should be a backup only.
At a public DC fast charger (50 to 350 kilowatts), the i4 can add 200 miles in about 35 to 40 minutes. The first 80 percent of charge happens quickly; the last 20 percent slows down to protect battery health. On a road trip, you'd typically charge to 80 percent, drive until the battery hits 20 percent, then charge again. This rhythm adds 30 to 45 minutes per 200-mile leg compared to a gas car.
Real-world efficiency matters more than the EPA rating. In cold weather, efficiency drops 20 to 30 percent because the battery and cabin need heating. In summer highway driving at 70 mph, you'll see 3.5 to 4 miles per kilowatt-hour. In mixed city and highway driving at moderate speeds, expect 4 to 4.5 miles per kilowatt-hour. Aggressive acceleration and highway speeds above 75 mph cut efficiency noticeably.
Federal tax credit and what BMW models currently may have access to for
The i4 qualifies for the $7,500 federal tax credit if you buy it new, but the rules have conditions. The car must be assembled in North America (BMW's i4 is built in Munich, Germany, so it does not currently meet the assembly requirement). As of 2024, this disqualifies the i4 from the full credit. Check the IRS website or fueleconomy.gov before you buy, because these rules change yearly and BMW may move production.
Some states offer additional incentives. California, New York, and Colorado have their own rebates for electric vehicles, ranging from $2,500 to $5,000. A few states offer tax credits or rebates on used electric vehicles. Your dealer can tell you what's available in your state, but do not rely on their estimate—contact your state's environmental or energy office directly.
Lease deals sometimes offer better value than purchase when federal credits are unavailable. BMW often subsidizes lease rates on the i4 to move inventory, which can make a three-year lease cheaper than buying and selling used.
Interior space, cargo, and comfort compared to a gas 3 Series
The i4 is slightly longer and wider than the old gas 3 Series, but the interior feels similar. Rear legroom is adequate for two adults; three across the back is tight. The trunk holds 17.7 cubic feet with the rear seats up—about 2 cubic feet less than a gas 3 Series sedan, because the battery floor takes space. Fold the rear seats and you get 52.4 cubic feet, which is enough for a week's worth of luggage or a small furniture piece.
The cabin is quieter than any gas car because there's no engine noise. Wind and tire noise are more noticeable at highway speeds. The ride is firm but not harsh; BMW tuned the suspension to feel planted without bouncing. In the M440i, the adaptive suspension adjusts stiffness in real time, which most drivers prefer on rough roads.
Climate control uses heat pump technology on both models, which is more efficient than resistive heating. In winter, the cabin warms up faster than you'd expect, and you can pre-condition the battery and cabin while plugged in, which extends range on cold mornings.
Maintenance, warranty, and long-term reliability
Electric motors have far fewer moving parts than gas engines, so routine maintenance is minimal. You'll rotate tires, replace cabin air filters, and top up washer fluid. Brake pads last longer because regenerative braking does most of the stopping. BMW recommends a brake fluid change every two years and a coolant flush every four years, but no oil changes, spark plugs, or transmission fluid.
The battery comes with an 8-year or 100,000-mile warranty, whichever comes first. BMW guarantees the battery will retain at least 70 percent of its capacity during this period. In real-world use, i4 batteries have held up well; most owners report less than 5 percent capacity loss after five years. After the warranty expires, battery replacement costs $15,000 to $20,000, though prices are falling as production scales up.
The i4 has been on sale since 2022, so long-term reliability data is still limited. Early models have had occasional software glitches and infotainment freezes, most fixed by over-the-air updates. No major structural or powertrain failures have been reported in significant numbers. BMW's reputation for build quality holds up, though some owners report panel gaps and trim issues at delivery.
How the i4 stacks up against other electric sedans
The Tesla Model 3 starts $10,000 cheaper, has longer range (up to 358 miles), and charges faster at Tesla Superchargers. The trade-off: the Model 3 interior feels sparse, the ride is harsher, and you're locked into Tesla's charging network unless you use an adapter. If you prioritize range and charging speed, the Model 3 wins. If you want traditional car controls and a quieter cabin, the i4 wins.
The Lucid Air is more expensive ($70,000+), offers more range (up to 516 miles), and has a more luxurious interior. The i4 is smaller, easier to park, and cheaper to insure. The Lucid is better for long-distance driving; the i4 is better for daily commuting and city driving.
The Genesis Electrified G70 is a closer competitor: similar size, similar price, similar range. The Genesis has a slightly more upscale interior and better warranty coverage. The i4 has better handling and a more recognizable brand. Both are solid choices; it comes down to whether you prefer BMW or Genesis styling and service.
Frequently Asked Questions
Can I tow a trailer with the i4?
No. BMW does not offer towing capability on the i4. If you need to haul a trailer regularly, the i4 is not the right car. The Tesla Model Y and Kia EV9 both offer towing, though with reduced range.
What happens to the i4's range in winter?
Expect 20 to 30 percent range loss in cold weather because the battery and cabin require heating. A 260-mile EPA range becomes roughly 180 to 210 miles in freezing temperatures. Pre-conditioning the cabin while plugged in helps, as does using seat heaters instead of cabin heat.
Is the i4 worth buying used?
Used i4s (2022–2023 models) are selling for $45,000 to $55,000, which is a $10,000 to $15,000 discount from new. You lose the federal tax credit and the full battery warranty, but you gain a known reliability track record. A used i4 with under 30,000 miles is a reasonable buy if the price is right.
How does the i4 handle in snow?
The eDrive40 (rear-wheel drive) can be squirrelly in snow because the rear end wants to slide. The M440i xDrive (all-wheel drive) is much more stable and predictable. If you live in a snowy climate, the M440i is worth the extra cost. Both models benefit from winter tires, which improve traction more than the drivetrain choice.
Can I charge the i4 at a Tesla Supercharger?
Not directly. Tesla Superchargers use Tesla's proprietary connector. The i4 uses the standard CCS connector found at Electrify America, EVgo, and other public networks. You can buy an adapter to use some Tesla locations, but it's slower and less reliable than using a CCS charger.
