The Czinger 21C VMax: A 1,250-Horsepower Testament to Extreme Hypercar Engineering
It’s rare for an automotive engineer, let alone a car brand, to attempt to reinvent the very concept of vehicle architecture. The vast majority of hypercars—even the electric ones—adhere to a design philosophy that has barely shifted in the last fifty years. But then there’s Czinger Vehicles. Based in Southern California, this company doesn’t just build cars; it builds machines using proprietary AI-driven additive manufacturing that transforms aerospace-grade metal into mechanical components that challenge what we think is structurally possible.
I recently had the privilege—and the sheer terror—of spending three days with the Czinger 21C VMax on a road rally tracing the wine-country backroads of Northern and Central California. As a reviewer with ten years of covering the automotive elite, I’ve driven everything from Bugattis to Koenigseggs. But nothing prepared me for the visceral, alien experience of sitting in a tandem cockpit with a 1,250-horsepower hybrid powertrain pushing me forward.
For years, the automotive world watched Czinger from the sidelines, intrigued by the fathers and sons (Kevin and Lukas Czinger) who founded Divergent Technologies and later, the automotive brand. We had them on The InEVitable podcast to discuss their 3D-printed hypercar and the radical technology behind it. The goal of this rally wasn’t just to hit a racetrack; it was to understand how a 7-figure machine built with what feels like pure science fiction operates in the real world.
The Future of Manufacturing: Inside Divergent Technologies
My journey began not at a traditional factory, but at Divergent Technologies. The need for a U.S. passport to enter the facility underscores the difference: Divergent is a major supplier of 3D-printed components for the Department of Defense. While the military hardware was kept discreet (though one piece resembled a rocket launcher), I was given a tour by CEO Lukas Czinger that felt like peering into the future.

The Future of Manufacturing: Inside Divergent Technologies
My journey began not at a traditional factory, but at Divergent Technologies. The need for a U.S. passport to enter the facility underscores the difference: Divergent is a major supplier of 3D-printed components for the Department of Defense. While the military hardware was kept discreet (though one piece resembled a rocket launcher), I was given a tour by CEO Lukas Czinger that felt like peering into the future.
Massive industrial printers were zapping powdered aluminum into components that looked more like bird bones than metal. This is where the Czinger 21C is born. Lukas explained that this process allows them to reach “Pareto optimality”—the point where adding or subtracting a single gram results in a negative outcome.
Consider this: An engineer specifies a rear suspension damper reservoir. It must fit within a tight spatial constraint and withstand extreme forces. Using generative design software, the system iterates thousands of potential solutions until it finds the absolute strongest and lightest form. It is evolution on fast forward. Beyond the DOD, nine automotive OEMs use this technology, including Aston Martin, Bugatti, and McLaren, whose recent halo cars feature these parts.
The Dual Personalities of the 21C
Czinger builds two primary configurations of the 21C. First, the high-downforce track monster (the standard 21C, named for the 21st century). Second, the low-slung, aerodynamic 21C VMax, designed specifically for maximum top speed and road comfort.
For the inaugural Velocity Tour, I found myself in a silver VMax. As I settled into the bizarre, tight cockpit, I instantly understood why Czinger compares the experience to being in a fighter jet. There’s no traditional cabin; it feels more like a canopy. I’ve experienced the intensity of riding shotgun in an Extra 330LT stunt plane, and the sensation is similar. The glass is less than a foot from your head, offering panoramic visibility but creating a unique egress experience. Sitting on the massive sill, pulling your knees up and tucking your feet into the narrow footwell while sliding your head under the roof is ridiculous but exhilarating.
The large sills serve a critical function: they house the batteries for the hybrid system. The 21C VMax is a hybrid hypercar with two 2.2-kWh battery packs (4.4 kWh total). It is not a plug-in hybrid; instead, the mid-mounted V-8 engine keeps the pack charged. This electrical power feeds two motors at the front axle, delivering a total of 500 hp to the front wheels.
The Heart of the Beast: Power and Transmission
The combustion engine is a Czinger-designed 2.9-liter twin-turbo V-8 that churns out 750 hp on California’s 91-octane premium unleaded. If you upgrade to 100-octane race fuel, the power jumps to 850 hp. The engine can also run on ethanol, which Czinger promises will yield even more power (estimated at a 10% increase), though official figures are still pending.
The engine drives the rear wheels through an Xtrac single-clutch automated semi-sequential gearbox. This is akin to the Xtrac seven-speed Pagani Utopia uses. However, Czinger has taken this formula and pushed it further. Not only is the transmission case 3D-printed, but they also use small 48-volt electric motors to execute shifts faster at lower speeds. This eliminates the lurching and surging that plagues traditional automated single-clutch gearboxes. The twin-barrel actuators work exactly as advertised, making low-speed maneuvers like pulling into gas stations or parking lots almost normal. Bravo, Czinger.
The Reality of Driving Extreme Speed
For the Velocity Tour, the Czinger team assigned Evan Jacobs, a professional driver, to ride shotgun. This is standard practice for big-dollar cars to ensure the $2,500,000 price tag doesn’t end up in a ditch. Thankfully, Jacobs quickly confirmed that I was not a threat to the VMax, and I was allowed to drive solo for the remainder of the rally.
We stopped by Laguna Seca for parade laps, but non-Czinger employees aren’t permitted to drive the VMax on track—even at the slow pace of a rally. However, I’ve learned that when you can’t drive, the best seat is the passenger seat. I scrambled into the bizarre rear seat, and the first thing to note is that calf size matters. My large calves were pressed between the carbon fiber tub and the seatback, and my feet barely fit in the footwell.
However, the visibility from the rear seat is incredible. It truly feels like being in a stunt plane, offering a novel perspective on a track I’ve visited over 1,000 times. Jacobs convinced the Skip Barber Racing School staff to let him take the VMax for a couple of 6/10ths laps.
The most impressive ride of my career was shotgun in an Aston Martin Valkyrie LMH race car, where I felt the blood pooling in my extremities under braking. The Czinger 21C VMax now holds the second spot on that list. Even without the high-downforce rear wing and not pushing to the limit, Jacobs demonstrated how a 21C can achieve the California Gold Rush.
The California Gold Rush: A New Benchmark
The California Gold Rush isn’t just a marketing slogan. In five days, a standard Czinger 21C set five production car track records across different courses: Thunder Hill, Sonoma Raceway, Laguna Seca, Willow Springs, and The Thermal Club. The brand then returned to Laguna Seca to reclaim the throne from the Koenigsegg Jesko Sadair’s Spear, clocking a ridiculous 1 minute, 22.30 seconds.
This lap time is faster than the fastest MotoAmerica Superbike lap ever recorded at Laguna, a 1:22.56.
Czinger claims a vehicle weight of around 3,600 pounds for the VMax—remarkably light for a 1,250-hp hybrid. To put this in context, the Ferrari SF90 Stradale Asseto Fiorano, the highest-performance version of a three-motor, twin-turbo V-8 PHEV (making 986 hp), weighs 3,839 pounds. The new Lamborghini Temerario, another three-motor V-8 hybrid with less power, pushes past the two-ton mark, weighing in at 4,185 pounds.
The SF90 and Temerario are the two quickest gasoline-powered cars MotorTrend has ever tested (the Ferrari for 0–60 mph and the Lambo for the quarter mile). If Czinger’s weight claims hold true, they have managed to beat two Italian legends on their debut. This is remarkable, especially considering Southern California isn’t exactly Modena.
The Road Trip: Where the Rubber Meets the Road
The rally route consisted mostly of true backroads: tight, winding, and weathered pavement—not the asphalt of supercar dream trips. Following the pack, navigating to stops, and hanging with the camera car made me feel like I was experiencing the VMax how most owners likely will: everyday life with a hypercar.
To my surprise, the VMax behaved like any other hyper-exotic. Take everything out of your pockets—the seats are tight, and there are no cupholders. Prepare for the attention: every male between 16 and 24 will be staring, following, waving, and revving their engines, probably screaming friendly obscenities.
Despite the expectations, the Czinger rides much better
