Mercedes-Benz announced that its performance brand is developing an electric SUV entirely in-house.

Most Mercedes-AMG models are based on Mercedes-Benz vehicles just with more high-performance chops.

This upcoming model will be one of a few models developed entirely by Affalterbach, Germany-based Mercedes-AMG.

This is just the sixth model fully developed by the AMG division and the first SUV in AMG’s 57-year history. The vehicle is currently called “Born in Affalterbach.”

The full-size SUV will be the second model built on the all-electric AMG.EA platform, with the company calling it an off-roader.

“SUVs have been among our most popular models for many years. With the ‘Born in Affalterbach’ SUV, we are responding to this trend by offering our customers a truly captivating high-performance off-roader based on the AMG.EA platform. Our new high-performance architecture follows a clear philosophy: ‘AMG First, EV Second.’ This means that the vehicles not only excel as electric vehicles but also embody the core AMG qualities of emotion and performance,” said Michael Schiebe, chairman of the board of management of Mercedes-AMG GmbH and head of the Mercedes-Benz G-Class and Mercedes-Maybach divisions, in a news release.

Development vehicles are set to undergo initial test drives this winter.
