BMW has released new details about their three-cylinder engine family.
Set to debut in a production model next year, the 1.5-liter TwinPower Turbo has a turbocharger, variable load control, direct injection and Valvetronic variable valve control (on petrol variants).
The petrol and diesel engines share a lot of commonality (60 percent components / 40 percent structure) which BMW says will allow for "considerable savings" in terms of development and production costs.
The engine's cylinders have a capacity of about 500cc and were designed for "thermodynamic efficiency, smooth, quiet operation and high-enjoyment." The engines also have a torsional vibration damper which reduces vibrations and promises to deliver an "extremely comfortable ride."
Detailed specifications haven't been announced, but the petrol engine will have outputs ranging from 122-224 PS (90-165 kW / 121-221 hp) and 180-240 Nm (133-177 lb-ft) of torque. The diesel, on the other hand, will produce between 82-184 PS (60-135 kW / 80-181 hp) and 225-330 Nm (166-243 lb-ft) of torque.
While the engines won't be mistaken for a V8, BMW says their exhaust note will be "extremely vivacious and sporty" because the "frequency of the sound of a three-cylinder engine increases 50 percent faster than that of a four-cylinder."
