Karma's Eximius 1 one-off hybrid sedan packs a 6.2-litre V-8 and 1,195 hp

Karma Automotive has launched its own personalization program, Eximius, and revealed its first bespoke build, the one-off Eximius 1, at the Concours at Wynn in Las Vegas. The car turns the plug-in series hybrid Revero platform into what Karma describes as a track-ready sedan.

The headline change is under the hood, where the Revero's turbocharged three-cylinder generator has been traded for a 6.2-litre V-8. Combined with the series hybrid drivetrain, the powertrain produces a total of 1,195 horsepower, well over 600 hp more than the car it is based on.

That output translates into a claimed sprint to 60 mph in 2.7 seconds and a top speed of 200 mph. The figures place the Eximius 1 in a different performance class from the Revero, and every mechanical choice follows from that jump in power.

Karma, a small American brand that rose from the remains of Fisker Automotive, has sold an evolution of the Fisker Karma over the past decade, badged as the Revero and later the GS-6. Our brand reference tracks the marque's history and its lineup of slinky plug-in hybrid sedans.

The company is sending the Revero off as it prepares to replace it with the new Gyesera, which carries the same design and powertrain philosophy forward. This one-off is how that model bows out: a farewell with a V-8 and a set of motors rather than a quiet retirement.

For the greater output, Karma fitted carbon-ceramic, two-piece slotted brake rotors and Öhlins semi-active dampers. The body is nearly two inches wider than a standard Revero, and carbon fibre appears extensively across the car, including exposed weave on the front fenders.

The finish is the car's most distinctive touch, with the blue paint fading in gradually over the bare carbon weave on the front doors. It is a single flowing transition rather than a two-tone split, and it runs into a dramatic aerodynamic package designed for track use.

Up front, a carbon splitter is flanked by gaping air intakes that carry an LED line, which links to the headlight elements to form an arrow pointing toward the centre of the nose. Two slim nostrils beside the lights give the car a look the source describes as a sinister sneer.

Vents cut into the front fenders release air pressure from the wheel wells, and a large panel marked with the number five incorporates an outlet that extracts hot air from the brakes. Below it, a billet aluminium exhaust tip hints at the performance on offer, and a fin stands proud near the rear doors.

The rear carries a massive diffuser and a towering wing, completing a package built entirely around downforce and brake cooling. The Eximius 1 rides on 21-inch magnesium centre-lock wheels, a choice that trims unsprung mass for lap times rather than for the high street.

Inside, blue-tinted carbon fibre covers the seats, steering wheel, centre console, doors and dashboard. The Recaro bucket seats pair blue Alcantara and blue leather on the base with Alcantara in a shade called Moondust above, and the pedals are machined from billet aluminium.

Karma has stripped the centre console back to only what is necessary on track, including a red emergency kill switch. It is the clearest signal that the Eximius 1 is built to be driven hard rather than shown in a collection, and the specification backs that up throughout.

The Eximius program itself is the wider news tucked behind the one-off. Karma says customers will be able to request changes to the body, powertrain and other performance components, and that it will build at most nine bespoke vehicles per production model line.

How Eximius compares to other bespoke programs

The move mirrors a trend already sweeping high-end automakers. Porsche runs Sonderwunsch, Bugatti operates Sur Mesure, and Rolls-Royce has its Coachbuild division, each catering to buyers who want a car altered beyond the standard options list and are prepared to pay for the privilege.

Karma's take on this differs in scale. A limit of nine vehicles per model keeps the program small even by the standards of those rivals, and it appears focused on performance hardware first, where Rolls-Royce leans toward bodywork and interior commissions. The Eximius 1 sets that tone.

We cover hybrid performance machines as part of our garage coverage, and the Eximius 1 is the most powerful Karma we have tracked by a distance. The brand has historically traded on elegant design and electric refinement more than outright grunt, which is what makes this reveal feel like a pivot as much as a send-off.

The first Eximius commission will be delivered to its owner in 2027, so the build itself is the story for now. Karma has not disclosed the price, the owner's identity, or which production model the next bespoke commission will be based on.
