Volkswagen presents its new engine 1.5 TSI, with turbo variable geometry, and Miller Cycle


Volkswagen has presented in Vienna new engine 1.5 TSI, a deep evolution on the well-known 1.4 TSI. Will be in the market at the end of 2016, and will be incorporated progressively in a multitude of models the group’s automobile: not only Volkswagen but also Audi, Seat or Skoda.

Within the code EA211 evo (marking differences with the current family EA211, which includes the 1.2 TSI and 1.4 TSI), new 1.5 TSI premiered technological improvements willing to look for the maximum performance and efficiency in fuel consumption. With four cylinders and 1498 followed cm3, will be available in two levels of power: 96 kW or 110 kW, 129 HP or 148 HP -likely to be marketed as 130 HP and 150 HP, respectively.

The less powerful it offers a maximum torque of 200 Nm, which are obtained in a flat manner and is very stretchy between 1,300 and 4,500 rpm. Its compression ratio is quite high for a petrol turbo, 12.5:1, adopting the Miller Cycle to a higher thermal efficiency. Later this engine will reach powers higher, but as we say, in the beginning, the bet is more conservative and will come with 96 kW or 110 kW.


Its turbocharger is a variable geometry, a real novelty for very rare up to now in a gasoline engine, which will help low regimes of the motor, where the exhaust gases have more difficulty in spinning the turbo. In addition, the system of direct injection also makes a leap forward with this fourth generation, reaching now 350 bar pressure.

In this 1.5 TSI also adopts an oil pump of variable type, and employ a a lubricant of very low viscosity 0W20. The engineers of Volkswagen have worked intensively to reduce the losses by internal friction to a minimum: all of this will help to a better utilization of every drop of fuel.

Its premiere will take place in the restyling of the Volkswagen Golf 2017, also extending to the Audi A3 or Seat Leon, though it will be a motor very versatile which will also be present in the suvs and even sedans from the Volkswagen Group. The 1.5 TSI will be the first engine of a family EA211 evo that will be expanded in the future, including other three-cylinder engines or plug-in hybrids.
