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 Colorado

Colorado is a top-10 EV state, driven by Denver's environmental consciousness, outdoor-oriented demographics, and the state's strong clean energy commitments. The Denver-Boulder corridor is one of the most EV-friendly markets in the Mountain West.

Incentives & Programs

Colorado offers a state EV tax credit of $5,000 for new EVs (income-qualified) and a $2,500 used EV credit. Xcel Energy offers a $500 rebate for Level 2 charger installation plus off-peak EV rates. The combined state + federal incentive can exceed $12,000.

Charging Infrastructure

The Front Range (Fort Collins to Pueblo) is well-covered. I-70 through the mountains has strategic DCFC placement, though mountain passes can limit range — plan for 20–30% more energy consumption on climbs.

Grid & Energy Source

Colorado is transitioning rapidly — Xcel Energy targets 80% carbon-free by 2030. Currently ~30% wind and solar, ~30% natural gas, ~25% coal (declining). EV emissions are moderate now but improving year over year.

ColoradoElectricity Rates & EV Savings

The average residential electricity rate in Colorado is $0.15/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.60/gallon, Colorado ranks as a favorable state for EV ownership.

Cold weather reduces EV range by 20–40% as the battery heats itself and the cabin. Use scheduled departure to pre-heat on shore power before driving. Your BMW i4's 81 kWh battery provides up to 301 miles of EPA-rated range. Real-world range may vary by 10–30% depending on temperature, speed, and terrain.

Tips for Charging Your BMW i4 in Colorado

Colorado'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:

Elevation gains on I-70 (e.g., Eisenhower Tunnel at 11,000 ft) can drain 20–30% more battery than flat driving — charge before mountain passes, not after.

Cold Rocky Mountain winters hit range hard. In January, expect 25–35% less range than EPA estimates.

Xcel Energy's EV Accelerate at Home program offers a $500 charger rebate and flat overnight rates around $0.06–0.08/kWh.

Ski resorts like Vail and Breckenridge are adding charging infrastructure rapidly — check resort parking lots for Level 2 options.
