But the truth is that the majority of people live in countryside, the economic level is imbalance. F or another, there isa trend of forming city in China and our society will have more and more old people. All these facts predict that semi-low coach will have a superiority indo mestic market. In order to meet the demand of economic and ‘ green ’ coach in our market, we design EQS5B coach in terms of study domestic market. We design EQS5Bby the standard of middle-class and aiming to travel these people from city to country. The coach has 36+1 seats and trys to satisfy the demand of class 3 style ’ requirements for its seats and hit the target of‘ low price ’. The principle of design this coach is to have more economic and practicality and reliable character s. Our chassis is EQS5Band we try to equip fitting gasoline tank and baggage box (nearly 3 stere). We have flexible material to decorate the inner of coach body and try to achieve an abundant space inside the coach. We make great effort to use current configuration and enhance petitive ability by the way of decreasing price and making more ec
