Czinger 21C Spyder Is a $2.75M 3D-Printed Convertible Hypercar

Czinger has added a third version of its 21C hypercar, and this one ditches the roof. The 21C Spyder is an open-top variant with 1,250 horsepower, a removable carbon-fiber roof panel, and a new 3D-printed braking system that fuses the caliper, upright, and hydraulic lines into a single piece.

The Spyder shares its basic architecture with the existing 21C HDF and VMax models, but it debuts a handful of firsts. The most significant is BrakeNode, an additively manufactured aluminum structure that replaces what would normally be several separate components. Czinger says the integrated design cuts unsprung mass by 1.5 pounds per corner, increases stiffness, and shortens stopping distances by as much as 15 percent.

Under the hood, the powertrain is unchanged. A 2.88-liter twin-turbo V8 revs to 11,000 rpm and produces 750 horsepower on its own. Two electric motors drive the front axle, and a third motor-generator unit adds another 500 horsepower, bringing the total to 1,250 hp and 691 pound-feet of torque. Czinger claims a 1.9-second 0-60 time and a 205-mph top speed.

The removable carbon-fiber roof weighs about 22 pounds, the same amount of additional reinforcement added around the windshield and A-pillars to compensate for the loss of the fixed structure. With the roof installed, the Spyder produces 3,307 pounds of downforce at 150 mph. Removing it drops that figure to 3,267 pounds, still more than most open-top production cars can manage.

Inside, Czinger introduces what it calls NeuralNode, another 3D-printed structure that wraps the dashboard, air vents, and button pods into a single component. The design replaces touchscreen controls with physical buttons and keeps the cabin layout focused on the driver.

Only 30 21C Spyders will be built at Czinger's Los Angeles facility. Pricing starts at $2.75 million, though fully specified examples can climb higher. The car is street-legal in all 50 states. BrakeNode will be standard on the Spyder and can be retrofitted to existing 21C HDF and VMax models.

Czinger's parent methodology, BioLogic engineering, uses algorithmic generative design to place material only where it contributes to stiffness, strength, or packaging. That approach produces the organic-looking metal structures visible throughout the car, from suspension control arms to the brake system and dashboard. The method has drawn interest from Aston Martin, McLaren, and Bugatti through Czinger's sister company, Divergent Technologies.

The Spyder is the most extreme expression of that formula yet, and it arrives at a moment when other automakers are still trying to figure out how to additively manufacture simple brackets. Czinger is already printing brake calipers and instrument panels.
