2021 Karma GS-6 Review

Like the Revero, the Karma GS-6 uses a plug-in hybrid powertrain. (The related GSe-6 is fully electric.) A pair of electric motors power the rear wheels and develop 536 horsepower and 550 lb-ft of torque. Once stored battery power is depleted, a BMW-sourced turbocharged 1.5-liter three-cylinder gasoline engine starts up to activate an onboard generator, which then supplies power to the motors. When Sport mode is activated, both stored battery energy and the gasoline engine/generator provide power to the motors. Karma hasn't supplied any acceleration times for the GS-6. But we'd guess its 0-60 mph sprint will be very similar to the identically powered Revero GT's, which has a claimed 4.5-second 0-60 mph time.

The GS-6 is a plug-in hybrid, but unlike other manufacturers, the 28-kWh battery pack can store enough energy to make everyday EV-only driving a reality. A fully charged battery will deliver an EPA-estimated 61 miles of guilt-free driving before the gasoline motor kicks in. It will take about four hours to fully charge using a Level 2 station, while plugging into a DC fast-charging station will charge the battery to 90% in about 35 minutes. Previous versions of the Fisker Karma and Karma Revero offered a solar roof that could power accessories or provide a few free miles of driving per day, but that feature won't be available on the GS-6 at launch.

Since the GS-6 is essentially the same size as the Revero GT, we believe it will also have an identical amount of interior space. Expect the GS-6 to offer a decent amount of rear legroom but cramped rear headroom because of the tapered roofline. The interior design also closely resembles the Revero GT, but the quality of materials might be a notch lower compared to its more expensive sibling. That said, reclaimed wood trim, ventilated front seats, and a choice of several leather colors remind you that you're still at the helm of a luxury sedan.

The 2022 Karma GS-6 is essentially a Revero GT at a lower price point, opening Karma's doors to a wider range of potential buyers. That said, some usability concerns, including the cramped rear seat, might put a damper on mainstream acceptance.
