Overview

BMW i4 at a glance

Quick model context before comparing photos and trim-level specifications.

Introduced in early 2021, the BMW i4 represents a significant step in the brand's electrification strategy, utilizing the fifth generation of the eDrive system. Built on a modular architecture designed to accommodate both combustion engines and electric motors, the i4 retains the dimensions of the 4 Series Gran Coupe, measuring 4,783 mm in length with a 2,856 mm wheelbase. However, the packaging of the 83.9 kWh battery pack in the floor adds considerable weight, bringing the rear-wheel-drive base model to 2,050 kg. To offset the mass, the 110-mm tall battery lowers the vehicle's center of gravity by 53 mm compared to a standard 3 Series sedan, aiming to preserve traditional driving dynamics.

Model guide

BMW i4 overview

Editorial context for design, cabin, performance, practicality, and buyer notes.

Design

Visually, the i4 stays close to the 4 Series Gran Coupe but integrates specific elements to signify its electric nature. The exterior features a closed-off front grille panel, aerodynamically optimized bumpers, and subtle blue accents around the badging. Standard wheel sizes start at 17 inches, with options up to 19 inches, while the M50 variant can be equipped with lighter alloys up to 20 inches. LED headlights are standard equipment, with laser optics available as an upgrade. The M50 also features a more aggressive exterior design to complement its higher performance.

Interior

Inside the cabin, the most prominent update is a large curved display dominating the dashboard. This setup combines a 12.3-inch digital instrument cluster and a 14.9-inch central touchscreen running BMW Operating System 8, complete with over-the-air update capabilities. Subtle blue trim on the steering wheel and center console hints at the electric powertrain. Comfort options include three-zone climate control, heated seats for all passengers with ventilation for the front, a heated steering wheel, and an available Harman Kardon audio system.

Performance

The i4 integrates the electric motor, transmission, and electronics into a single housing. The eDrive40 features a single rear-mounted motor producing 340 hp and 430 Nm of torque, enabling a 0-100 km/h time of 5.7 seconds and a WLTP range of up to 590 km. The all-wheel-drive M50 utilizes dual motors for a combined 544 hp and 795 Nm, dropping the acceleration time to 3.9 seconds, with a range of up to 510 km. Both use an 83.9 kWh (gross) battery and support 200 kW DC fast charging, allowing a 10% to 80% charge in just over half an hour.

Practicality

As a five-door liftback, the i4 offers a practical cargo area with a 470-liter trunk capacity, easily accessible via the large rear hatch. The 2,856 mm wheelbase provides adequate interior room for five occupants, making it suitable for daily family use. Standard rear air suspension helps maintain ride height and comfort regardless of the load in the trunk, adding to its versatility.

Safety and tech

The i4 is available with a comprehensive suite of approximately 40 electronic driver assistance systems, many of which are standard. Available safety and convenience technologies include surround-view cameras, adaptive cruise control, lane-keeping assist, and blind-spot monitoring. The performance-focused M50 model adds an adaptive suspension setup, variable ratio steering, and upgraded brakes to handle the increased power and weight.

Buyer notes

When comparing the i4 models, buyers should weigh the need for the M50's significant power advantage and all-wheel drive against the eDrive40's longer range. The eDrive40 is well-suited for maximum efficiency, while the M50 caters to those seeking higher acceleration. Prospective owners should also note that exact equipment levels, such as the availability of laser headlights or the Harman Kardon system, may depend on regional trim structures and optional packages.
