The side profile of the BMW 1 Series (three-door) resembles that of a thorough-bred racing car. The drawn out doors and the frameless window reinforce the sporting appeal. The appealing side skirts further add to the car’s looks. 

In the four-cylinder petrol engines which the BMW 116i, 118i and 120i house, fuel is injected into the engine at the rate of about 3 times a second. This incredible level of precision is achieved by the positioning of the piezo injectors which are located centrally between the valves. The cars are able to operate in the lean-burn mode for extended periods and at for far higher revs.
