Volkswagen will become the first manufacturer to build a four cylinder engine equipped with a shut-off system when production of its new 1.4L TSI engine next year.
This innovative design allows two cylinders to close down while the engine is running between 1,400 and 4,000 rpm and producing between 25 and 75 Nm of torque. Cylinders 2 and 3 instantly burst into life once the driver hits the accelerator with any vigour.
The resulting consumption figures speak volumes, with a saving of 0.4L of fuel being saved every 100 km. When combined with the car’s start/stop function that number becomes 0.6L/km. Even better; if driven at a very sensible speed – 50 km/h, in third or fourth gear – almost one litre per 100 km can be saved.
