The Czinger 21C was created through the innovative use of 3D printing technology by the American company Czinger Vehicles. Production commenced in 2021, with an anticipated total of 80 units to be manufactured, and the first deliveries are expected to take place in 2024. Among these 80 units, there are two distinct configurations planned: a road version and a track-focused variant known as the 'Lightweight Track'. 

The design of the 21C features a centrally positioned driver's seat, with a tandem passenger seat located directly behind the driver, effectively reducing the overall width of the cockpit. Additionally, the vehicle incorporates a unique system where the brake calipers and suspension components are integrated into a single assembly referred to as the BrakeNode.

The 21C features a hybrid powertrain that includes a custom-designed twin-turbo V8 engine with a displacement of 3 litres, positioned centrally at the rear. This engine is complemented by two electric motors situated at the front, which draw energy from a lithium titanate battery. Together, this innovative setup generates an impressive output of 1,250 horsepower at 10,500 rpm, which is delivered to the rear wheels through a seven-speed sequential transaxle equipped with a hydraulic multi-plate clutch. Additionally, there is an option available that boosts the power to 1,350 horsepower. The 21C has achieved several remarkable lap records for production vehicles. In August 2021, driver Joel Miller recorded a time of 1:25.44 minutes at Laguna Seca, utilising road-legal Michelin Pilot Sport Cup2R tires along with a high downforce variant of the Hypercar. This record was surpassed in August 2024 by Miller, who set a new benchmark of 1:24.75 minutes. Furthermore, in 2024, the 21C established additional records at the Goodwood Festival of Speed Hillclimb and the Circuit of the Americas, with Chris Ward achieving times of 48.82 seconds and 2:10.70 minutes, respectively.
