"The Chrysler Thunderbolt Concept introduced a new wave of designs and industry technological accomplishments. The body was comprised of aluminum and the roof was a retractable, electrically controlled hardtop. There were no door handles; rather they were operated by the push of a button. The windows were controlled by hydraulic power. The headlights were also carefully concealed in the bodywork. The aerodynamic design continued to the fully enclosed wheel wells. There were no A pillars."
