Aside from the aluminum frame, that article just described a saturn s-series.
Quote:
The front-engine, front-drive Start features composite body panels with bonded in color, flush-mounted glass and an aerodynamic teardrop shape to reduce weight and wind resistance, thereby enhancing the vehicle’s overall fuel economy. The car’s spaceframe is made of lightweight aluminum and steel components.
Like the original Smart that had snap-on body panels that could be changed, the Start features a composite roof panel that can be easily removed and replaced as a customized accessory, changing the look of the car. While the Start has the look of a sleek hatchback, the rear glass is fixed and there is a traditional trunk lid for a separate luggage compartment.
