New spy shots catch the upcoming BMW i4 on the road, including showing off the four-door EV's interior. The German brand intends to expand its electric vehicle range in the coming years, and this coupe-inspired saloon begins production in 2021.

The spy shots show that the i4 has an exterior look that's akin to a 4 Series Gran Coupe, but the pair aren't identical. Judging from these images, the stylish, electric saloon has a different nose but retains the sleek roof.

The interior of the test mule has BMW's current layout that combines a digital instrument cluster and infotainment display directly next to it. These screens aren't functioning in this car, though, and an auxiliary monitor appears to be doing most of the work currently.

The i4 will ride on BMW's highly adaptable CLAR platformIt'll reportedly be available with 60- or 80-kilowatt-hour battery packs, and buyers will allegedly be able to choose from a single electric motor driving the rear wheels or a dual-motor, all-wheel-drive setup. Some variants will be able to hit 62 miles per hour in four seconds. The estimated, real-world driving range will likely be below 300 miles.

In addition to the i4, BMW also has the two other EVs on the immediate horizon. The iX3 will arrive in 2020 as an electric version of the brand's existing crossover, although with slight design tweaks. Meanwhile, the iNext SUV in 2021 will introduce the automaker's new modular platform and will allegedly be capable of Level 3 autonomous driving.
