It's basically just like the GTS with less range.

Towards the end of last year, Karma Automotive launched a more potent version of its Revero GT luxury electric saloon, the Revero GTS. It came with promising performance figures: a quicker zero to sixty time, and an overall range of 380 miles with the help from its range-extender three-cylinder engine. The Revero GTS goes on sale during the early part of this year for $149,950 (approx. £116,100 at the current exchange rate).
