The 2026 BMW i4 scores 57/100 on cost of ownership — 26 points below the sedans median. The Sedan class median 5-year ownership cost is $44,011 (15,000 mi/yr, national average rates). Largest annual recurring expense: insurance.
The 2026 BMW i4 scores 6/100 on driver assistance — 37 points below the sedans median. All scores reflect standard equipment at base MSRP; optional driver-assistance packages are not scored.
The 2026 BMW i4 scores 61/100 on powertrain — 6 points below the sedans median. Key figures: 109 MPG-equivalent combined, 301 miles electric range, 335 hp.
Verdict
The 2026 i4 brings electric performance to BMW's Gran Coupe platform with strong structural crash-test results from the IIHS. But the safety picture is incomplete: NHTSA has not rated it, and the IIHS flagged poor base headlights and below-average automatic emergency braking. Ownership costs are high, and the driver-assistance package on the base trim is minimal. For EV buyers drawn to BMW's driving dynamics, the i4 is compelling behind the wheel — but the safety and value equation leaves room for improvement.
Good fit for: Daily commuter
Best for
- Strong IIHS structural crash-test results across all categories
- Strong electric performance in a distinctive Gran Coupe design
Watch out for
- NHTSA has not rated this vehicle
- IIHS rated base headlights Poor and AEB below average
- High ownership costs with minimal base driver-assistance

Powertrain
Electric-powertrain efficiency weighed with long-term ownership confidence.
Reliability from NHTSA complaint records, adjusted for how many were sold. How we measure it
Combines real-world energy efficiency (EPA-verified MPG or MPG-equivalent vs. class) with long-term ownership confidence (warranty coverage, platform maturity, and reliability data). Methodology →
Driver Assistance
Modest driver-assistance capability, but highway support and parking convenience and hands-free automation are limited.
💡 Tracks where the car can drive itself (highways vs. local roads) and how much driver supervision is needed (up to fully driverless).
PoorStandard driver assist — no hands-free operation
Combines highway support, parking convenience, and hands-free automation capability into one score. Methodology →
Livability
Passenger space and everyday maneuverability, scored within its class.
Combines how comfortably this vehicle fits passengers and cargo with how easily it maneuvers in real-world conditions — normalized within its Sedan segment for fair comparison. Methodology →
Safety
Based on standard crash-avoidance features.
Combines crash-test protection — NHTSA frontal, side, and rollover ratings plus the IIHS crashworthiness sub-tests (small- and moderate-overlap front, side, headlights) — with standard crash-avoidance technology. New model years without published crash tests are scored on crash-avoidance features alone and capped until tested. Methodology →
