2016 BMW I3 0.6L Hybrid electric · DS66 FHV

Running costs for the BMW i3 are generally modest thanks to its electric-first operation, with official WLTP figures suggesting 100+ miles of pure electric range from a full charge when new. Real-world range in 2026 from a nine-year-old battery is likely to be 70-90 miles in summer and considerably less in winter. Home charging costs work out at roughly 3-4p per mile on a typical domestic tariff, while the range-extender petrol engine sips fuel at around 40-50mpg when called upon. Road tax is zero for this hybrid electric vehicle as it sits below the current £10 minimum threshold, and VED exemption from the London Congestion Charge and ULEZ brings significant urban savings.

Insurance is the one area where the i3 surprises buyers, typically falling into group 21-29 depending on the variant — not cheap for such a small car, reflecting its premium badge and repair costs. Tyres are a specific running cost consideration: the i3 uses narrow front and wider rear tyres in unusual sizes, and replacements cost more than mainstream hatchback equivalents. Annual maintenance is generally low for owners running a BMW specialist rather than a main dealer, with services typically £180-£300 depending on whether it is the interim or full inspection.

Begin the physical inspection with the high-voltage battery state of health via a diagnostic tool, as this is the single most critical and expensive item on any i3. Visually inspect the charging port and cable for damage, and confirm both AC and any rapid-charging functionality operates correctly. Examine the 647cc range-extender engine bay (rear-mounted under the tailgate) for oil leaks, corrosion on coolant pipes, and the condition of the auxiliary 12V battery, which if failing can cause misleading drivetrain warnings.

Move on to the body and structure: the i3's CFRP (carbon-fibre reinforced plastic) shell does not rust but is vulnerable to impact damage and UV degradation, particularly on the grey-painted plastic panels common to early examples like this 2016 car. Inspect the rear doors, sills, and roof for cracks or fading. Inside, check the suicide rear doors operate smoothly and that the quirky window frameless glass is intact. On the MOT record side, although the history shows no defects, the model-level data flags coil springs and windscreen washer issues as common failure points for the i3 — inspect the washer jets, fluid level, and listen for suspension knocks over speed humps as part of your test drive.

Finally, verify all electrical systems including the heating (which uses a heat pump on later i3s and can be costly to repair), infotainment, and climate control. Test the regenerative braking modes and confirm the i3 drives in both pure EV and range-extender modes without warning lights. A pre-purchase inspection by a BMW i specialist or an EV-trained independent garage is strongly recommended given the unique technology on offer.
