BMW i4 2021

Launched in 2021, the BMW i4 is part of the Bavarian manufacturer's electrification strategy, offering a fully electric D-segment sedan. Aimed at customers seeking performance and technology, it comes in three variants: the eDrive 35 entry-level (286 hp), the mid-range eDrive 40 (340 hp) and the sporty M50 (544 hp). All feature the same 80.7 kWh gross battery and benefit from BMW's modular platform, equally suited to combustion and electric powertrains. The i4 faces rivals such as the Tesla Model 3 and Audi e-tron GT in a segment where the balance between practicality, range and dynamic character is a major issue.

Design and livability

Measuring 4.78 m long and 1.85 m wide, the BMW i4 adopts classic sedan proportions while displaying its electric nature through distinctive details: a full grille adorned with blue inserts, redesigned LED headlights and taillights, and specific alloy wheels. The absence of a combustion engine does not impact interior space, with a 2.86 m wheelbase providing correct rear-passenger comfort.

The trunk offers 470 liters in standard configuration, expandable to 1,290 liters with the rear backrest folded. This positive volume for a sedan reveals BMW's commitment to maintaining a familiar architecture despite electrification. Interior trim relies on quality materials, notably quilting and trim pieces, without revolutionizing the feel compared to the brand's combustion offering.

Powertrain and performance

The i4 offers three power levels based on the same electric motor in progressive outputs. The eDrive 35 delivers 210 kW (286 hp) and 400 Nm of torque, enabling 0-100 km/h in 6 seconds. The eDrive 40 reaches 250 kW (340 hp) and 430 Nm, reducing this to 5.7 seconds. The M50, the high-performance version, peaks at 400 kW (544 hp) and 795 Nm in all-wheel-drive with twin motors, achieving 0-100 km/h in 3.9 seconds—a result positioning this model among the fastest electric sedans on the market.

All versions adopt rear-wheel drive except the M50, which benefits from all-wheel drive. Top speed is capped at 190 km/h for eDrive 35 and 40, and 225 km/h for M50. These motor architectures ensure balanced weight distribution and assertive road dynamics, though base versions lack the sportiness of the M50.

Range and charging

Equipped with an 80.7 kWh gross battery common to all three versions, the i4 displays variable ranges depending on power and weight: eDrive 35 claims 483 km in WLTP cycle, eDrive 40 reaches 590 km (best range in lineup), while M50 manages 510 km due to added weight and all-wheel drive. These figures placed the i4 among segment references at launch, though sporty versions suffer notable range penalties.

For charging, the i4 accepts up to 180 kW DC for eDrive 35 and 210 kW for eDrive 40 and M50, allowing 10 to 80% refill in approximately 31 to 35 minutes at a fast charger. In alternating current, all versions are limited to 11 kW, requiring several hours on a home wallbox (7-11 kW standard power). This asymmetry between DC and AC speeds remains typical of premium electric vehicles.

Equipment and technology

The cabin integrates two combined touchscreens: a 12.3-inch display for instruments and a 14.9-inch screen for infotainment. This iDrive 8 system offers a redesigned interface with improved ergonomics and updated graphics. 5G connectivity and over-the-air (OTA) updates allow the i4 to receive software improvements without visiting a dealership.

Driver assistance includes standard segment features: adaptive cruise control, lane-keeping assist and collision detection. Compatibility with Android Auto and Apple CarPlay ensures seamless smartphone integration, while the myBMW app provides remote charge status and range monitoring. The absence of native Vehicle-to-Load (V2L) function limits energy return possibilities to external devices, a weak point against some competitors.
