Based on these spy photos, it doesn't look like much will change between the A and C-pillars. That goes for the interior, too. This might come as a bit of a disappointment, as the car has a slick interior design, but it sacrifices a lot in terms of ergonomics and space. On the outside, the Revero will get new front and rear fascias with new lighting and a longer hood.
Don't expect too many changes to the powertrain. The GM-sourced turbo inline-four is paired with electric motors for a healthy 403 horsepower and 981 pound-feet of torque, though the sheer size and weight of the Revero means it's not particularly fast. Rumors suggest that the next Karma model, the Atlantic, will ditch the GM powertrain all together.
