Ars Technica has driven the Czinger 21C, a $2,350,000 hybrid hypercar built by the father-son team of Kevin and Lucas Czinger in Torrance, California. The carbon-fiber-bodied 21C centers on a bespoke 2.88-liter twin-turbo flat-plane crank V8 that screams to 11,000 rpm, augmented by three electric motors — one per front wheel plus a crank-driven starter-generator — for a combined 1,250 hp and 691 lb-ft of torque. A seven-speed automated manual transaxle sends power to the rear wheels, propelling the sub-3,700-lb VMax model to 60 mph in 1.92 seconds and a 253 mph top speed. The track-focused High Downforce variant recently set lap records at five California circuits during a 1,000-mile road trip. Production is capped at 80 units.

What distinguishes the 21C isn't just performance but how it's made. Parent company Divergent Technologies uses generative design software and large-scale metal additive manufacturing to "grow" components — suspension arms, gearbox case, rear subframe — as organic lattice structures optimized for load paths. Printers deposit roughly one kilogram of metal per hour; the rear subframe takes two days. This eliminates traditional tooling, allowing Divergent to produce parts for Bugatti, McLaren, and defense contractors like Lockheed Martin in the same facility with zero changeover time.

The driver sits centrally in a single-piece carbon safety cell with a passenger tucked directly behind in tandem fighter-jet fashion. Pushrod double-wishbone suspension and carbon-ceramic brakes handle dynamics, though Czinger plans to introduce a 3D-printed "Brake Node" later this year integrating caliper mount, suspension pickup, and fluid conduit into one lighter, stiffer part. Entry requires a controlled descent over high sills, but the cockpit delivers a raw, mechanical connection absent in most modern hypercars.

The 21C proves additive manufacturing can produce road-legal, record-setting vehicles at hypercar volumes. If Divergent scales this tooling-free approach to higher-volume segments as promised, it could rewrite automotive production economics — making low-volume specialization as cost-effective as mass production.
