Daimler Southeast Asia presented the ten micro-cars of the smart brand manufactured by Mercedes-Benz in front of the art museum in Singapore in August of 2008. An innovation in a twin sense. These city cars, found in many metropolises, have not yet been introduced to the market in this Southeast Asian country. So far, smart is only available in Malaysia, Thailand, Indonesia and Brunei. The tanks were filled with alternative fuels, among them biodiesel derived from jatropha, a plant that grows wild in Asia, one with a high oil content but inedible for man and beast alike. Instead, farmers use hedgerows of the plant to safeguard their grain against pests and erosion.
