Construction techniques used by Alfa Romeo has been imitated by other carmakers, and in this way, the Alfa Romeo body designs have often been very influential. The following is a list of innovations, and where appropriate, examples of imitation by other car manufacturers: thumb|Alfa 6C 2500 S 1960s: Aerodynamics: The 116-series Giulia had a very low Cd. Toyota, in particular, sought to produce a similarly shaped series of vehicles at this time. 1970s: Fairing of bumpers: In order to meet American crash standards, Alfa Romeo formulated a design technique to incorporate bumpers into the overall bodywork design of vehicles so as to not ruin their design lines. The culmination of this design technique was the 1980s Alfa Romeo 75. The process was widely copied, particularly in Germany and Japan. 1980s: The Alfa Romeo 164: The design process and influence of this car is almost completely out of all proportion to previous Alfa Romeos. The 164 introduced complete CAD/CAM in the manufacturing cycle, with very little directly made by hand. In addition, the 164's styling influence continues into the present-day line of modern Alfa Romeos. Most manufacturers incorporated design ideas first expressed in the 164 into their own designs, including greater reliance on on-board computers. 1990s: The pseudo-coupé: The Alfa Romeo 156 and 147, while four-door vehicles, represented themselves as two-doors with prominent front door handles, and less visible rear door-handle flaps. Honda has used this design style in the latest Civic hatchback, and a somewhat similar idea is also seen in the Mazda RX-8 four-seat coupé and Renault Clio V. 2000s: The Brera and 159: These vehicles' design, by Giorgetto Giugiaro, have proven influential in sedan and coupé styling, demonstrating that concept vehicles are often immediately translatable into road car form, providing that initial design takes place using CAD systems.
