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.

EV Ownership in Rhode Island

Rhode Island has growing EV adoption, largely in the Providence metro. As the smallest state, range anxiety is essentially nonexistent — a single charge covers the entire state multiple times over.

Incentives & Programs

Rhode Island offers the Drive Electric RI rebate (up to $1,500 for new EVs). National Grid RI and Providence Energy offer off-peak EV charging rates. The state participates in the TCI (Transportation Climate Initiative) framework.

Charging Infrastructure

I-95 through Providence is well-served. Newport and coastal areas are growing. Given the state's tiny size (48 miles long), there's no long-distance concern — any DCFC on I-95 can serve most of the state.

Grid & Energy Source

Rhode Island's grid is a mix of natural gas (~90%) and small renewables — the state lacks space for large-scale generation. However, offshore wind projects planned for RI Sound will significantly change this picture.

Rhode IslandElectricity Rates & EV Savings

The average residential electricity rate in Rhode Island is $0.27/kWh, which is above the national average of $0.17/kWh. With a gas price of $3.70/gallon, Rhode Island ranks as a favorable state for EV ownership.

Tips for Charging Your BMW i4 in Rhode Island

Rhode Island's cold 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:

Rhode Island's tiny size means a single overnight Level 2 charge easily covers a week of commuting.

National Grid RI's off-peak EV rate is ~$0.10/kWh — low enough to make EV economics compelling despite the high base rate.

Providence's compact geography makes Level 2 public charging more practical here than in most states.

Offshore wind development offshore RI will make the grid substantially cleaner by 2027–2028.
