Mercedes-AMG has been spotted testing a prototype for an updated E63. The super sedan looks to adopt styling tweaks planned for the entire E-Class range for its mid-cycle update, and we're hopeful of some additional horsepower being extracted from its twin-turbocharged V-8.

EV startup Karma will roll out a pair of concept's at next month's Auto Shanghai 2019, one of which was penned by Pininfarina. A teaser shot hints at a repeat of the mustache-shaped grille, which proved to be a controversial feature of the original Fisker Karma, which Karma now sells in updated form as the Revero.

Aston Martin will roll out an SUV called the DBX later this year. Prototypes are currently testing in public and reveal a number of design details pegged for the high-performance off-roader.
