BMW i4 review

Overview

The BMW i4 is an electric saloon with 5 seats, a 83.9 kWh battery and a quoted WLTP range of 300 miles. On paper it suits families who want space without moving up to a van. Prices start at around £51,000, with leases quoted from about £469 a month.

Its headline specification point is straightforward: drives like a proper BMW, silently. The sections below break the published figures down and set them against the other electric cars in our UK database.

Design & practicality

Bodystyle is a saloon with 5 seats and 470 litres of boot space. Against every EV in the database that puts it around mid-pack for outright carrying capacity, and around mid-pack among other saloons.

Boot volume is typical of the class: fine for a weekly shop and a couple of cases.

Range & charging

The quoted WLTP range is 300 miles from 83.9 kWh of usable-plus-buffer capacity — above average in the database for distance between charges. Real-world figures are typically 10–25% lower in cold weather and at sustained motorway speeds.

That is a big-battery setup with solid rapid-charging speeds. As with any EV, the running-cost picture depends far more on whether you can charge at home overnight than on the charging speed itself.

Performance

The published 0–60mph time is 5.7 seconds, which puts it above average for acceleration here and makes it brisk by the numbers. Electric drivetrains deliver that pull instantly from a standstill, so town-speed responses tend to feel stronger than the figure suggests.

Tech & features

We score cabin technology at 9/10 based on published equipment levels, which is above average across the database. The specification highlight is that drives like a proper BMW, silently.

Expect a large central screen, over-the-air updates and driver assistance as standard on most trims.

Price & value

New prices run from £51,000 to £70,000, with three-year-old used examples from around £28,500 and leases quoted from £469 a month. That sits at the upper-middle of the electric cars in this database, and the middle of the saloons specifically.

Our value score, which weighs the price against range, space and equipment, is 6/10. Whether it works out cheaper than your current car depends on your mileage, fuel price and charging setup — the cost calculator does that maths properly.
