Turns out it will offer exactly the same range and efficiency as the Karma Revero GT.

Karma Automotive recently announced that it intends to offer a less expensive version of the Revero GT plug-in hybrid - the GS-6 - and in the recent days it emerged in the EPA database.

As it turns out, this new model has the same range and efficiency numbers as the Revero GT, which indicates that the powertrain is the same.

The all-electric range of the 21" wheel version is 61 miles (98.1 km), which is a lot for a PHEV, but not that much considering its 28 kWh battery. The efficiency is not the strongest point of the model:

When we look closer into details, we can also note that those optional 22-inch wheels are really bad for efficiency. They eat 13% (or 7 miles) of all-electric range and 18% (or 50 miles) of the total range.
