Recently for sale the facelift of the Volkswagen T-Roc, the range of this SUV hides an important ace up its sleeve, and it is a renewed 1.5-liter TSI gasoline engine. The 150 hp block made its debut in this model, and has now been renewed with a commitment to maximum efficiency. A key driver in the brand’s new strategy, of which we will tell you all the details.
the gasoline engine 1.5 TSI Evo It was one of the great novelties of the Volkswagen T Roc. One of the most modern engines from the Wolfsburg manufacturer that combined technologies never seen before. It was the first Miller cycle block equipped with a variable geometry turbochargera supercharging system until now only used in diesel engines, and the first to add to this system the cylinder deactivation ACT.
With the Volkswagen Golf tweaked the block using the propulsion and resulting in the 1.5 e-TSI, retaining the same power and torque specifications. Now, the German brand has given a new twist to this engine, resulting in the engine 1.5 TSI Evo 2. And, once again, it will be the T-Roc range that will debut it, progressively being mounted on other models. One block has been so thoroughly revised that it can almost be rated again, and we tell you all about it.
The keys to the Volkswagen 1.5 TSI Evo 2
Known as “EA211», does not change the block, nor the four-cylinder architecture, nor its variable geometry turbo, although the direct gasoline injection system has been renewed for increase the injection pressure up to 250 bar, which has also made it necessary to reinforce the cylinder walls with a new plasma technology that reduces the friction of the components, increasing efficiency. Another novelty fully affects one of the keys to efficiency, the system of cylinder deactivationnow called “ACT plus».
This system disconnects the second and third cylinders when the engine is at low and half loadso it has now been adjusted to work in a range wider motor rotational speed in this specific situation. Volkswagen has also replaced the current catalytic converter with a three-way one without precious metals inside to perform this function, so it is cheaper, also adding a gasoline particulate filter closer to the engine. The result will be a further reduction in consumption and emissions.
But not only will it stay here as one more option, but the German brand has already confirmed that eThis 1.5 TSI Evo 2 is the combustion engine that will support the thermal part in the new generation of plug-in hybrids, confirming information that we advance to you. A very interesting block that relieves the old and exploited 150 hp 1.4 TSI, but that will allow the power of the PHEV versions to be increased from the current 245 CV up to a great 272 CV.
