Volkswagen is clearly not abandoning the combustion engine over electric vehicles

So far, we’ve become very aware of Volkswagen’s intentions to transition to a cleaner future by introducing more and more all-electric vehicles into its ID family. Based on Volkswagen’s versatile MEB platform specially developed for all-electric offerings, volkswagen made sure to plan big for a greener future. Does this increased focus on all-electric offerings mean Volkswagen has kept internal combustion engines out of its focus? Certainly not.

While car manufacturers are on the verge of phasing out internal combustion engines, Volkswagen has been careful not to completely abandon internal combustion engines and is still working on its development by unveiling the latest generation of its famous gasoline engine 1 .5 TSI. Dubbed the TSI evo2, this new iteration of the highly acclaimed 1.5-litre four-cylinder turbocharged petrol engine has made its debut in Europe and will make its way to other markets in the coming months. Here we will discuss how Volkswagen improves the 1.5 TSI and how it will be instrumental in shaping the fate of the Volkswagen family’s IC engine globally.

The debut of the new 1.5 TSI Evo2

With the new 1.5 TSI evo2, Volkswagen has reduced its fuel consumption and CO2 emissions, which will help it become cleaner and greener than ever. The new engine was co-developed by Volkswagen teams at its Wolfsburg and Salzgitter plants. The revised engine made its debut in Europe under the hoods of two facelifted models of the Volkswagen family, the T-Roc and the T-Roc Cabriolet. However, this new engine will be introduced in other compact and midsize offerings from the Volkswagen family over the coming months.

What’s new on the 1.5 TSI Evo2

The most significant change in the new 1.5 TSI evo2 engine introduced by Volkswagen is the evolved shape of its cylinder deactivation system. Called the Active Cylinder Management System, ACTplus, this engine now boasts improved activation and deactivation of both cylinders and an optimized combustion process with both cylinders in action for smoother operation.

When ACTplus is activated, the first and fourth cylinders continue to fire, while the second and third cylinders do not fire at low and medium speeds and load conditions. When the accelerator is pressed again, the second and third cylinders reactivate.

To reduce emissions and make it a cleaner engine, Volkswagen changed the positions of the three-way catalytic converter and gasoline particulate filter, bringing them closer to the engine. This repositioning of components has improved the efficiency of the emission control system. In an attempt to make its stance on sustainability stronger than before, Volkswagen has reduced the use of precious metals in the manufacture of this engine, which goes hand in hand with reducing emissions to meet future emission standards. .

Volkswagen also uses high-quality components like a variable geometry turbocharger, a high-pressure injection system operating up to 350 bar, plasma-coated cylinder walls and pistons with cast cooling. The TSI evo2 uses the same combustion process that the previous generation of this engine, the 1.5 TSI evo1, follows. In this engine, the high-compression intake valves close early, while the engine is powered by a boost of Variable Turbocharger Geometry (VTG) technology.

The new 1.5 TSI Evo2 is ready for the future

In addition to complying with the future emission standards mentioned above, the new 1.5 TSI evo2 can also run on fuels using ingredients from renewable energy sources. Volkswagen also claims that this new engine is compatible with electrification, as it can hybridize at different levels. Volkswagen claims to develop up to 268 hp in a plug-in hybrid version.

With this claim, the new 1.5 TSI evo2 becomes the primary internal combustion engine to support Volkswagen’s claims to achieve a 70% sales share by its electrified models by 2030. All these changes will make it ready for the future to meet future emission standards, such as Euro 7. This engine will also be one of Volkswagen’s main powertrains in developing markets, where going all-electric may not be a feasible option for a few years. due to the lack of charging infrastructure in these markets.

The journey of the 1.5 TSI Evo

The Volkswagen 1.5 TSI Evo has remained one of the most integral parts of the EA 211 family of inline-three and four-cylinder turbocharged petrol engines, which debuted almost a decade ago in 2011. Since 2012, engines under the EA 211 family, including the 1.5 TSI, have powered millions of cars so far. Every year, Volkswagen produces four million powertrains belonging to the EA 211 family at eleven Volkswagen production plants.

The first generation version of the 1.5 TSI, the 1.5 TSI Evo1, debuted in 2016 as a replacement for the previous generation 1.4 TSI from the same EA 211 family. Since then, it has powered several popular offerings from Volkswagen. Globally, the 1.5 TSI has made its presence in cars ranging from compact SUVs like the T-Cross to full-fledged sedans like the Passat.
