A 6.2-litre V8 replaces the Revero's generator unit, with delivery to an unnamed client set for 2027.
Karma Automotive pulled the generator out of a Revero. Dropped in a 6.2-litre V8. The car, called Eximius 1, debuted October 31 at the Concours at Wynn Las Vegas under a new one-of-one commission program the Californian company had not previously disclosed. One build. One client. No name given.
For a company that assembles vehicles in the hundreds annually — not the thousands — a 1,195-hp track-configured hybrid is a pointed statement about where Karma intends to operate. According to Karma Automotive's product announcement, published October 31 2026, the Eximius program sits above the brand's existing Studio personalisation tier and allows clients to rework powertrain and body hardware alongside Karma's engineering team. The Revero, , has never exceeded 536 hp in any series configuration.
The Power Split: 550 hp From the Engine, 645 hp From the Pack
Karma breaks the 1,195-hp total into two sources: 550 hp from the 6.2-litre V8 combustion engine and 645 hp from the battery-electric side of the series-hybrid drivetrain. That 550 + 645 = 1,195 hp figure is Karma's own arithmetic, published in its October 31 announcement. At least two other outlets cited a figure closer to 1,212 hp — a 17-hp discrepancy that Karma has not yet reconciled publicly. The V8 accounts for roughly 46 percent of total output; the electric motors carry the remaining 54 percent. Karma claims a 0–60 mph time of 2.7 seconds and a top speed above 200 mph, though the company labels that top-speed figure an estimate. No independent dyno or track verification has been carried out. The car is still in development as of the Las Vegas premiere date, with handover to the commissioning client scheduled for 2027. Those are marketing numbers, not certified results — a distinction worth keeping in view.
McCammon: 'Deletes the Word No'
Marques McCammon, president and chief executive of Karma Automotive, framed the Eximius 1 as proof of what the company's engineering team can accommodate when a client removes conventional constraints. "The Eximius program effectively deletes the word 'no' from conversations about what's possible," McCammon said in the October 31 product announcement. He went further, describing the Eximius 1 as carrying "the most powerful Plug-in Series Hybrid powertrain and vehicle ever developed." That second claim is unverified and unqualified — Karma did not specify which third-party data set or governing body it used to reach that conclusion. The announcement was made at the ultra-high-net-worth automotive commission market, a segment where provenance and exclusivity routinely substitute for independently tested specification sheets. McCammon's language is deliberate. Whether the numbers hold up once the car leaves Karma's facility in Moreno Valley, California, is a separate question.
A Send-Off Car for a Line That Already Ended
Here is the awkward part of the story. Karma confirmed separately that Revero series production has concluded. The Eximius 1 is built on Revero architecture — which means the most powerful vehicle Karma has ever made is based on a discontinued platform. The commissioning client is buying a one-off derivative of a car Karma no longer builds for general sale. That is not disqualifying, but it raises questions about parts supply, warranty coverage, and long-term factory support for a vehicle whose donor line no longer runs. Karma has not addressed any of those points publicly. The company's forthcoming Gyesera Grand Coupe — a range-extended electric coupe — is reaching dealerships in December 2026 and represents Karma's actual production future. The Eximius 1 exists in a different category entirely: a bespoke commission on legacy hardware, unveiled the same month a new model launches. Whether that timing was choreographed or coincidental, Karma has not said.
What the Hardware Actually Looks Like Against Series Revero Spec
The standard Revero GTS — Karma's highest series-production variant — was rated at 536 hp and used a 1.5-litre three-cylinder turbocharged engine purely as a generator, driving no wheels directly. The Eximius 1 replaces that generator with a 6.2-litre V8 inside the same series-hybrid architecture, producing 1,195 hp combined — a 123 percent increase over the GTS figure. The body is nearly two inches wider than standard to accommodate extended wheel arches. Every exterior panel except the outer skin is pre-impregnated carbon fibre. Wheels are 21-inch magnesium centre-lock units finished in satin black. Braking comes from carbon-ceramic rotors — two-piece, slotted — and suspension is Ohlins semi-active. A standard Revero GTS ran 18-inch aluminium wheels and conventional steel brakes. In terms of hardware category, the Eximius 1 and the GTS share a name and a silhouette. Most everything else has changed.
What the Eximius Program Means for Future Karma Clients
The Eximius tier now sits above Karma's Studio personalisation programme, which previously allowed finish, trim, and limited option changes. Under the new structure, a client working with the Eximius team can alter powertrain, body structure, and performance hardware — in direct collaboration with Karma's design and engineering staff, according to the October 31 announcement. The practical effect for any future Eximius client is access to a bespoke engineering resource inside a low-volume manufacturer. That is a different proposition from commissioning a one-off from a coachbuilder. Karma retains engineering ownership of the platform and provides a completed vehicle rather than a modified shell. The commissioning client for Eximius 1 has not been publicly identified. No pricing has been disclosed. Karma has not confirmed whether a second Eximius commission is in progress, nor whether the programme has a client cap. Those gaps in the public record are not accidental — scarcity, in this market, is part of the product.
Karma was founded in 2014 after acquiring assets from the bankrupt Fisker Automotive, itself launched in 2007. The Revero line ran in various forms for roughly a decade before production closure in 2026. Eximius 1's 21-inch magnesium wheels alone mark the first time Karma has specified magnesium as a wheel material in any production or commission vehicle. One car. No confirmed price.
