In July 2021, Boldmen, which was founded a year earlier, presented its first car in the form of the 2-door, 2-seat CR4 roadster. The third generation of the BMW Z4 was used as the basis for the development of the vehicle, visually significantly modifying it, also implementing proprietary technical changes.[2]

The Boldmen has developed its own exterior design, with widely spaced headlamps as well as the distinctive hexagonal-shaped centrally located air intake. The rear part of the body has also undergone changes, with a widely spaced Boldmen inscription, as well as the pattern of the front part of the body - lamp shades with cased lenses.[3] The BMW 3-liter six-cylinder B58 engine, which initially powers the Z4 in the M40i variant, has undergone extensive changes. As a result, the vehicle develops a maximum power of 414 hp and 610 Nm of maximum torque, developing a maximum of 250 km/h (160 mph) and 100 km/h (62 mph) in 3.9 seconds. The exhaust system has been redesigned, leaving only the 8-speed automatic transmission unchanged.[4]
