BMW Concept i4 previews 523-horsepower Tesla Model 3 rival

BMW is working on a new generation of its 4-Series and this time around a battery-electric car called the i4 will fill in for the 4-Series Gran Coupe.

The i4 is still a year away from launch but BMW on Tuesday previewed the design of the fastback sedan with the Concept i4.

The Concept i4 is actually the second concept to preview the i4 as the i Vision Dynamics concept unveiled in 2017 was also a precursor to the planned production model. The Concept i4 more closely resembles the production i4 than the earlier i Vision Dynamics, and some of the lines will also filter across to gasoline versions of the redesigned 4-Series—including the tall grille.
