The 21C VMax: A 1,250-HP Hybrid Hypercar Pushing the Limits of Extreme Engineering
For years, a persistent buzz surrounded the California-based automotive startup Czinger. Known for their ambitious blend of avant-garde design, lightweight construction, and high-performance hybrid drivetrains, the company sought to redefine the hypercar landscape. Their first production vehicle, the Czinger 21C, made waves with its radical center-steer layout, striking aesthetics, and aggressive performance targets. However, the ultimate expression of this engineering philosophy is arguably the Czinger 21C VMax—a track-focused variant stripped of the large rear wing found on its counterpart.
The opportunity to experience this vehicle, particularly as part of a comprehensive road rally across California’s wine country, offered a unique perspective on what happens when additive manufacturing meets extreme automotive performance. This journey from factory floor to winding roads reveals a car that challenges conventions and redefines the very notion of what’s possible in a production vehicle.
From DOD-Grade Technology to the Open Road: A Factory Tour
Getting behind the wheel of a Czinger is not a simple matter of showing up at a dealership. The company’s parent organization, Divergent Technologies, is at the forefront of applying iterative artificial intelligence and 3D printing to solve structural challenges across various industries. Because Divergent Technologies serves the Department of Defense (though specific military applications are confidential), visitors must present government-issued identification to enter the facility. The entire tour, provided by CEO Lukas Czinger, was an immersion in bleeding-edge technology.
One of the most striking aspects of the factory tour was the sight of the massive 3D printers in operation. These machines utilize powerful lasers to fuse powdered metal, creating components that possess the structural integrity of natural bone while remaining astonishingly lightweight. This technology allows Divergent to achieve what CEO Lukas Czinger describes as “Pareto optimal” design—a state where any further reduction in mass would negatively impact performance.
Consider the design of a remote reservoir for a rear suspension damper. An engineer defines the constraints: the spatial limits within the chassis and the forces it must withstand. The software then iterates through thousands, if not millions, of potential designs. The result is an organic, fractal-like structure that is both strong enough to handle extreme stress and light enough to contribute minimally to the vehicle’s overall weight. While the DOD is a significant partner, Divergent also supplies its additive manufacturing expertise to nine automotive OEMs. Aston Martin, Bugatti, and McLaren have publicly acknowledged their use of Divergent’s components in models such as the DBR22, Tourbillon, and W1, respectively. Some industry observers also speculate that the control arms on the Ferrari F80 may originate from Divergent’s advanced manufacturing processes.
The Architecture of the 21C: A Tale of Two Variants
Czinger produces two distinct versions of the 21C, though the names themselves can be a bit confusing. The high-downforce version, which retains a full aerodynamics package, is known simply as the 21C. The variant I was tasked with driving, the VMax, is essentially a road-legal and track-oriented configuration with the extreme rear wing removed. While the model is technically the 21C VMax, the VMax designation is prominent, and the “21C” badging is notably absent from the vehicle’s exterior.
The inaugural “Velocity Tour” was a three-day, 500-mile road rally traversing Central and Northern California’s renowned wine country. My assigned test vehicle was finished in a sophisticated silver livery. The choice of a road rally rather than a purely track-focused event was deliberate. While everyone is understandably eager to know how the Czinger 21C VMax performs when pushed to its absolute limits—its 1,250-horsepower output, 3D-printed architecture, and futuristic design are headline-grabbing features—the true test of such a radical hypercar lies in its everyday usability. Can a vehicle that looks like it’s been beamed down from another planet function as a road car?
Stepping into the Cockpit: A Jet-Fighter Experience
The driver’s position in the Czinger 21C is anything but conventional. The vehicle features a tandem seating arrangement, meaning the driver is positioned in front of the passenger, similar to a jet fighter or a tandem bicycle. This layout is central to the car’s aerodynamic efficiency and overall weight distribution. Calling the cabin a “greenhouse” feels inaccurate; it is more akin to a canopy.
Climbing into the driver’s seat requires a specific technique. The massive carbon fiber sills, which contain battery packs, necessitated a somewhat gymnastic maneuver. One must first position their legs externally, then pull their knees up, pivot on their seat, and finally tuck their feet into the footwell before pulling their head under the roofline. This process, while undoubtedly effective for weight distribution, is decidedly unwieldy.
The massive sills are also a necessity for the hybrid powertrain. The 21C VMax is a plug-in hybrid, with 2.2 kWh of battery capacity housed in each sill, totaling 4.4 kWh. A mid-mounted V-8 engine powers a motor on the front axle and keeps the battery pack topped off. The V-8 itself is a 2.9-liter twin-turbocharged unit designed by Czinger, producing 750 hp when running on California’s 91-octane premium unleaded. However, when fueled with 100-octane race gas, the V-8’s output increases to 850 hp. Czinger also produces a variant that can run on ethanol, which is expected to offer an even greater power bump, although specific figures have not yet been released.
The gas engine is mated to an Xtrac single-clutch automated semi-sequential gearbox. This is similar to the seven-speed Xtrac transmission used in the Pagani Utopia. However, Czinger takes this a step further by not only 3D-printing the transmission case but also using small 48-volt electric motors to facilitate faster shifts at lower speeds. This innovative approach effectively smooths out the “drunken” surge often experienced with automated single-clutch transmissions at low speeds. During maneuvers such as navigating gas stations, restaurants, and hotel parking lots, the twin-barrel actuators performed admirably, ensuring the car felt surprisingly normal in urban environments. This smoothness at low speeds is a remarkable achievement for such a performance-oriented vehicle.
Track Dominance: A Record-Shattering Performance Legacy
While I was granted full driving privileges for the 500-mile rally, the opportunity to drive the Czinger 21C VMax on a racetrack was limited. Similar to practices employed by Bugatti and Pagani, Czinger provided a professional driver, Evan Jacobs, to accompany the car during the rally. The company wanted to ensure the safety of the $2.5 million hypercar. It wasn’t until later that evening that Jacobs confirmed I posed no threat to the vehicle, and I was permitted to drive solo for the remainder of the trip.
We did stop by Laguna Seca Raceway for a few parade laps, but for safety reasons, non-Czinger employees were restricted from driving the VMax on the track, even at the significantly reduced pace of the rally participants.
As I have learned through experience, even if you are not the most skilled driver, riding along in a high-performance car can be incredibly revealing. I had the opportunity to ride in the rear seat, which, true to its jet-fighter layout, offers exceptional visibility through the side windows. It reminded me of riding in an Extra 330LT stunt plane—an unusual and novel perspective, especially for someone who has experienced thousands of track laps from the driver’s seat.
Jacobs and I convinced the Skip Barber Racing School staff, whose track day we were visiting, to allow him to take the VMax for a few “6/10ths” hot laps. The most intense hot lap I have ever experienced was in the passenger seat of an Aston Martin Valkyrie LMH race car, where the braking forces were so extreme that blood pooled in my extremities. The Czinger 21C VMax now occupies the second spot on that list. And remember, Jacobs was not pushing the car to its absolute limit, nor was the massive rear wing installed.
Even at reduced speeds and without the high-downforce wing, it was easy to understand how the Czinger 21C achieved what the company calls the “California Gold Rush.” This campaign saw the VMax set five production car track records in a single week—at Thunder Hill, Sonoma Raceway, Laguna Seca, Willow Springs, and The Thermal Club—driving from each circuit to the next. Later, Czinger returned to Laguna Seca to reclaim the track record from the Koenigsegg Jesko Sadair’s Spear. The lap time, a breathtaking 1 minute 22.30 seconds, is even faster than the fastest MotoAmerica Superbike lap ever recorded at Laguna, which stands at 1:22.56.
Czinger claims a vehicle weight of approximately 3,600 pounds, which is remarkably light for a 1,250-horsepower hybrid. For context, the Ferrari SF90 Stradale Asseto Fiorano, the most potent version of Ferrari’s three-motor, twin-turbo V-8 plug-in hybrid system (producing 986 hp), weighs 3,839 pounds. The new Lamborghini Temerario, another three-motor twin-turbo V-8 hybrid (with less power than the Cz
