1951 GM LeSabre

Designed by legendary GM stylist Harley Earl, the LeSabre embodied the styling of early fighter jets in its basic design. This is especially prevalent at the nose of the concept, which strongly resembles a turbine intake, allowing the car to not only have a futuristic appearance, but to also have a level of aggression that was absent from production Buick models of the time. In addition to looking stylish, the LeSabre concept was also a technological showcase that included features such as a dual fuel system that burned alcohol and conventional gasoline, as well as a specially-designed moisture sensor that automatically raised the convertible top in the event of a sudden downpour. All of these features put the LeSabre way ahead of its time, while also making the car a herald of what would eventually become the modern iteration of the automobile.
