The Toyota Prius leads the pack in eco-friendly hybrid vehicles. The new third-generation Prius has the world’s best fuel consumption, solar-powered ventilation system, plant-derived plastics in its moulded interiors and deluxe floor mats made of Ingeo™ fibers.

Ingeo, a family of plant-derived biopolymers from 100-percent-renewable resources, is produced by NatureWorks LLC, Minnetonka, Minn. Traditional floor mats, made of petroleum-derived nylon resin, use nonrenewable fossil fuels. The manufacturing process for Ingeo reduces fossil fuel use by 65 percent and cuts carbon dioxide (a greenhouse gas) by 90 percent in comparison, according to NatureWorks.
