About the 2026 BMW i4

The BMW i4 is the electric version of the beloved 4 Series Gran Coupe — a four-door fastback sedan that doesn't compromise driving dynamics for electrification. Available in eDrive40 (RWD, 301 miles) or M50 (AWD, 270 miles), it's the EV for driving purists.

Advantages

✓BMW's signature rear-wheel-drive dynamics translated brilliantly to electric

✓Stunning fastback design — one of the best-looking EVs available

✓M50 trim produces 544 hp with world-class handling

✓iDrive 8.5 is among the most refined automotive UIs available

Considerations

✗200 kW DCFC, while good, is below 800V competitors like Ioniq 5 or EV6 GT

✗M50's AWD adds weight that limits range to 270 miles

✗Gran Coupe roofline reduces rear headroom

✗No front trunk — limits total storage

Ideal Buyer

Driving enthusiasts who refuse to buy an EV that doesn't feel like a driver's car. BMW 3 or 4 Series owners ready to go electric. Buyers for whom style and dynamics matter as much as range.

vs. Gas Equivalent

Direct EV equivalent of the BMW 4 Series Gran Coupe. Gas equivalent fuel economy would be approximately 27 MPG for a comparable gas 4 Series.

Tips for Charging Your BMW i4 in California

California's moderate climate and charging infrastructure have specific implications for BMW i4 owners. Here are practical tips to maximize range and minimize charging costs in this state:

Charge between midnight and 9 AM on TOU-EV2 plans to get rates under $0.15/kWh despite the high base rate.

California's solar boom means midday grid electricity is often the cleanest in the world — if you have solar, export during the day and charge at night.

In wildfire conditions, utility PSPS events can cut power — keep the battery above 50% during fire season as a buffer.

HOV sticker for solo EV drivers is a major quality-of-life perk in LA and Bay Area traffic — prioritize getting it after purchase.
