"The Cadillac Aera (Aero + Era) launches Cadillac's philosophy of 'Art and Science' into new territory by taking an innovative and stylistic approach to ultra-lightweight vehicle design. Aera is a 1,000-pound, 2+2 touring coupe, with a range of 1,000 miles before refueling; attributes achieved without compromising size, capacity and safety.
"Optimum efficiency, minimum parts: Aera's highly advanced body structure utilizes a 3D lattice, mono-formed frame. This polyhedral structure is similar to configurations found consistently in nature, e.g., inside the grouping of bubbles. The structure is formed from unique, alloy-utilizing, semi-solid freeform manufacturing, creating a naturally strong, extremely lightweight frame. All major body parts, including interior components, are essentially 'grown' into a single part lattice structure.
"Renowned Cadillac smoothness and quietness are accomplished using the harnessed power of compressed air via a highly efficient Pneumatic Drive System (PDS). Its 10,000 psi composite air storage tank has ample capacity for a 1,000-mile range. Flexible, pressurized air cells in the exterior skin, similar to material developed for the NASA Mars Rover airbags, enhance passive safety and interior comfort. The flexible polymer skin optimizes aerodynamics and functions as an ultra-lightweight alternative to conventional body panels and glass.
"Additional technologies include an All-In-One (AIO) wheel system, combining rotary actuator propulsion, steering and suspension functions. A drive by wireless system decreases the mass of electrical components. Vehicle to vehicle communication (V2V) promotes active safety.
"The Cadillac Aera embodies a stylistic, lightweight, minimalist approach to long distance luxury touring."
