. . . All of the new petrol engines feature spontaneous responsiveness, high torque characteristics and supreme power delivery. The 1.5 litre three-cylinder engine reaches its maximum torque of 220 newton meters at an engine speed of 1,250 rpm; this can be increased briefly to 230 newton meters by means of the overboost function. The 141 kW/189 bhp four-cylinder model actually achieves a torque of 280 newton meters with the same engine speed (300 Nm with overboost). The maximum speed of all new petrol engines is 6,500 rpm.
The engine’s sporty character is favored by the position of the turbocharger integrated in the exhaust manifold. The short path of the exhaust stream enables the charging system to be activated promptly and effectively. In addition, the emissions pattern of the engines is optimized by the positioning of the catalytic converter and an electronically regulated waste gate. An efficient and precisely dosed fuel supply system facilitates direct injection with centrally positioned injectors between the valves and directly next to the spark plugs. The electronic control for camshaft positioning and the stroke of the intake valves are further technological elements that optimize the responsiveness and the consumption and emissions readings of the new petrol engines for MINI. . . .
