How Much Does It Cost to Charge a BMW i4 in South Carolina?

Quick Answer

Charging a 2026 BMW i4 at home in South Carolina costs approximately $40/month — that's $0.040/mile and saves $934/year compared to a 28 MPG gas car at South Carolina's gas price of $3.30/gallon.

Sedans offer excellent aerodynamics and some of the highest efficiency ratings in the EV market, making them among the most cost-effective EVs to run daily. Hot climates can reduce EV range by 10–15% due to air conditioning load and battery thermal management. Pre-conditioning your battery while still plugged in minimizes this effect.

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.
