Rayo getting close to being the fastest Mile road car.
Testing resumed on April 4 2026 at Space Coast with a new Billet engine from Underground Racing. During engine calibration tests, the car proved to be incredibly stable and safe at extreme speeds. Power delivery is astounding and we were able to achieve a 270MPH/ 435kph standing mile without even trying for a record.

World’s Fastest Coachbuilt car?
Countless hours of designing, aero studies, tuning, and testing involved in the construction of the 7X Design Rayo paid off when during aero validation tests at IDIADA, Spain we managed a top speed of 447.8 kph (278 MPH) thanks to its power and stability. We may have broken a record.
