The BMW i4 is the first pure electric 4-door coupe model launched by the BMW brand, and is built on the CLAR platform. From the appearance point of view, the car still maintains a high degree of similarity with the fuel version of the BMW 4 Series. The whole car incorporates a modern sports design style. The front face adopts a large-sized closed air intake grille, and high-end The M50 version also has the M logo inlaid on the upper part of the grille. The style of the headlight groups on the left and right sides of the new car is also consistent with the fuel version of the BMW 4 Series. Laser headlights are optional, and the distance of the high beam can reach 500 meters when the starting conditions are met.

  In terms of body size, the specific length, width and height of the new model are 4785×1852×1455 mm, and the wheelbase is 2856mm. The new model has an elegant body arc on the side. The vehicle is not deliberately taller due to the addition of battery modules. It maintains the same appearance as the fuel version. However, the too short rear door makes the lines of the vehicle appear not to be stretched enough. Compared with the front face design, the rear shape of this model is much simpler. The iconic LED taillights paired with the M sports package effectively enhance the sporty aura of the vehicle. The small rear wing on the trunk lid of the new car is exclusive to the M50 version, distinguishing it from the 40 model. The outer ring of the blue sky and white clouds logo is inlaid with a blue edge, indicating that this is an electrified BMW.

  The interior design of the BMW i4 is still the familiar style. The decorative panels throughout the center console are added with carbon fiber patterns. The biggest change on the center console is the rectangular one-piece screen and the one-piece LCD instrument. The dashboard and multimedia display screen are one of the important elements of the latest generation of BMW cabin design, and they do not appear too obtrusive when added to this interior that has been used for many years. The M steering wheel directly in front of the driver has a three-spoke design. The thick body has an excellent grip. The shift paddles at the rear have been cancelled, and there is no paddle function to adjust the power recovery intensity. The size of the 14.9-inch central control display screen is not too exaggerated. The new ID8 operating system inside is relatively smooth and can be operated through touch and knobs. Depending on the configuration, the interior seats of the new model are wrapped in imitation leather and genuine leather fabrics respectively. In terms of functions, they have electric adjustment of the main and passenger seats, and electric passenger seat memory. The M50 version provides integrated sports seats with moderately soft and hard internal fillings and a backrest that fits the human body, providing good comfort and lateral support.

  The BMW i4 seems to have a relatively normal rear row, but the actual riding experience is not friendly. First of all, it is limited by the too short tailgate, which makes it difficult for rear passengers to get in and out of the car. At the same time, the rear seat cushions are too short and the floor is high. The passenger's thighs are directly suspended in the air, and the comfort performance is only satisfactory for short-distance emergency use.

  The BMW i4 40 version adopts a single-motor layout, with a maximum output power of 340 horsepower, a peak torque of 420 Nm, a battery pack capacity of 83.9 kWh, and a CLTC comprehensive cruising range of 625 kilometers. The M50 version is driven by dual motors, with a combined maximum output power of 544 horsepower, a peak torque of 795 Nm, and an acceleration time of 0 to 100 kilometers in 3.9 seconds. The battery pack capacity is also 83.9 kWh, but the CLTC cruising range is only 560 kilometers. As the first pure electric 4-door coupe model launched by BMW, the BMW i4 has inherited BMW's sports genes and integrated sports and technology through new detailed design and multimedia upgrades.
