Car manufacturers started to chase 'style' from the late 1920s and the design of cars became more important, particularly as it was becoming harder to achieve difference by unseen technical innovation within the car. Coachbuilders sprang up to give alternative bodies but as the 1930s dawned the standard steel body helped to lower costs. Cue the car designer to provide brand unity and badge style. The coming of the monocoque body saw the body becoming more integral to the whole engineering of the vehicle, and a good designer could achieve excellent engineering AND beautiful lines. Italy led the world of design from early on, with Lancia coming up with the monocoque body in the 1920s. Aerodynamics gave cars speed on the track, but the suggestion of 'streamlining' gave cars street style, and this was picked up by names such as Alfa Romeo, Ferrari and Maserati who went out to the best Carozzeria to achieve it.
