At the start of the 21st century, petrol and electric hybrid models appeared to fill the gap. Toyota’s Prius model was voted car of the year 2005 in Europe and gained a similar accolade in the United States. Experimentation with other energy sources continues This increasing competition has encouraged vehicle firms to seek out new products to try to  strengthen their commercial positions. As a result, in the US market annual sales of sports- utility vehicles, pick-up trucks, and mini-vans exceed 7.0 million units. These domestic and  leisure “truck” sales are in addition to car sales. In response to environmental concerns  about emissions, firms are developing less “dirty” vehicles such as hybrids powered by  petrol engines and electric or fuel-cell power units, the latter for use in urban areas. The  industry is trying to tap new segments that meet consumer needs more precisely such as  cross-over vehicles that combine attributes such as executive car comfort and off-road  capability or extra passenger space. As yet, such vehicles have marginal market shares. Myth 1: You need to plug in a hybrid car Today's hybrid cars don't need to be plugged in, but a growing number of consumers wish they had a plug-in hybrid. DaimlerChrysler is the furthest along in the development of a plug-in hybrid system. The company is using the Sprinter commercial van as the platform for testing and evaluation of a commercial plug-in hybrid drivetrain. Myth 2: Hybrid batteries need to be replaced Andrew Grant, a taxi driver in Vancouver, British Columbia, operated a Toyota Prius as a Yellow cab for almost five years. He put more than 200,000 miles on his first Prius taxi. The parts that wore out were not hybrid-related components. Myth 3: Hybrids are a new phenomenon In the first few years of the 20th century, thousands of electric and hybrid cars were produced. This car, made in 1903 by the Krieger Company, used a gasoline engine to supplement its battery pack. Myth 4:
