The fastest road car to ever lap Laguna Seca and Circuit of the Americas is nearly as quick with its roof off. The reality-bending Czinger 21C is, comfortably, the fastest car around a race track being built in the United States right now. It took five different California track records last year, then retook the record at Laguna Seca again later in the year as part of a long-standing rivalry with Koenigsegg.
As a central-cockpit two-seater with a canopy, it also happens to be one of the most unique cars built anywhere on Earth right now. The latest variant, the 21C Spyder, makes the car even more unique without taking all that much away from its on-track bona-fides. The 21C Spyder is the first Czinger available as a convertible. The main roof structure is a removable glass canopy, and when the canopy is installed, downforce is actually equal to the 3307 pounds at 150 miles per hour produced by the fixed-roof 21C HDF model.

Not only does that make the 21C Spyder still fast enough to nearly equal the record-setting pace of its fixed-roof relative, it gives the car the grip it needs to potentially fight for road-legal track records with the roof off.
The Spyder also benefits from arriving on the road later than both the 21C HDF and the low-drag V-Max. Inside, it features an upgraded steering wheel and dashboard setup, adding not new creature comforts like improved air conditioning ducts. The interior of the debut car is finished in a striking brown and blue two-tone, adding to the idea that this is the closest thing Czinger has made yet to a grand tourer.
Even more significant are the changes underneath the wheels, which hide a braking system integrated directly into the car’s suspension uprights. Czinger calls this technology BrakeNode, and it claims that it reduces unsprung mass by 6 pounds over the already weight-optimized assemblies previously installed on other 21C models. The company also claims that it raises stiffness by 30%, makes brake pad changes easier, and, thanks to more even distribution of force, reduces stopping distance by up to 15%.
