The Boldmen CR4 is a two-door roadster produced by German automobile manufacturer Boldmen.[2] It was introduced in 2021.
In July 2021, Boldmen, which was founded a year earlier by Harald Käs, Michael Käs, and Friedhelm Wiesmann,[3] 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.[4]
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.[5] 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 300 kW (408 PS; 402 hp) and 610 N⋅m (450 lbf⋅ft) of torque, allowing it to reach an electronically limited top speed of 250 km/h (155 mph) and accelerate from 0-100 km/h (62 mph) in 3.9 seconds. The CR4 S variant has power upgraded to 368 kW; 493 hp (500 PS) and 700 N⋅m (516 lbf⋅ft) of torque, with an electronically limited top speed of 270 km/h (168 mph) and a 0-100 km/h (62 mph) time of 3.7 seconds.[2] The exhaust system has been redesigned, leaving only the 8-speed automatic transmission unchanged.[6]
