With the increase in UHSS (Ultra High Strength Steel)etc that we are faced with on vehicles today, and the associated problems, guess what, it gets even better, with the development of Carbon nanotubes.
Carbon Nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with length-to-diameter ratio of up to 28,000,000:1, which is significantly larger than any other material. These cylindrical carbon molecules have novel properties that make them potentially useful in many applications in nanotechnology, electronics, optics, and other fields of materials science, as well as potential uses in architectural fields. They exhibit extraordinary strength and unique electrical properties, and are efficient conductors of heat and electricity.
CNTs are currently being designed for auto body construction.
This chart shows a comparison of Tensile strengths of different steels.
Advanced Boron and Carbon Nanotubes are future materials that we will start seeing in the next few years.

The long-range goal is to build planes, automobiles and other things with buckypaper composites. The military also is looking at it for use in armour plating and stealth technology.

Toyota Solar Panal
Toyota plans to install solar panels on the roof of the next generation of Prius hybrid cars, according to a report in Monday's edition of the Nikkei newspaper.
The panels, which are expected to begin appearing on the high-end version of the gasoline-electric hybrid car as early as next spring, will supply part of the 2 to 5 kilowatts needed to power the air conditioning, MarketWatch cited the Japanese business daily as reporting. Kyocera will reportedly supply the panels.
The move would make Toyota the first major automaker to incorporate a solar-power generation system into a mass-produced car.
