Plastics make things possible, or so say the major plastic manufacturing companies in their ads. It turns out that there's some truth to the tagline, as automakers are increasing the amount of plastic parts in vehicles in an attempt to reduce weight and emissions. While many consider steel to be the most desirable material to pound out automobiles, the use of plastic is outgunning metals pound for pound on new cars. Even luxury brands like BMW and Porsche are using more plastics in their vehicles than ever before, and both see the trend continuing. Composites such as carbon fiber and kevlar prove that plastics can perform just as well as steel when properly designed and engineered.

Despite the overall goal of reducing weight and cutting vehicle emissions, most plastics still trace their roots to petroleum. Automakers such as Mazda and Mitsubishi are experimenting with bioplastics, which are made from natural ingredients such as sugars.

Tata Motors has disclosed that it is working with General Electric's plastics division to develop solutions for its forthcoming ultra-low cost small car.

Widely referred to in India as the "Rs 1-lakh" (100,000 rupees) car, the Tata project could be a breakthrough product for the company, with potential domestic sales of 1 million units per year. The four-door, rear-engine car will sell for only $2,200 - less than half the price of current entry level cars in the Indian market.

Tata chairman Ratan Tata has stated that the small car will make extensive use of plastics for the body, replacing welding with adhesives to decrease assembly costs. In an effort to cut down on distribution costs, the company is considering shipping modular car kits to small, local business units combining assembly, sales and service under one roof.

GE plastics are already in widespread use by automakers, primarily with a view to reducing weight (thereby increasing fuel efficiency). The Smart ForTwo makes extensive use of plastic body components, and BMW's 6-Series uses GE plastic front fenders.
