Volkswagen modified the 1.5 TSI four-cylinder engine, it should have lower emissions and consumption

Volkswagen does not publicly hide the fact that its main goal is a complete transition to electric mobility, among other things, due to recovery from the scandalous case with the results of a fraudulent emissions measurement called “diesel jet”.

Obviously, the VW developers were not upset with the combustion engines either, because they presented us with a new version of the famous four-cylinder 1.5 TSI evo2 gasoline.

The 1.5 TSI unit is the mainstay of Volkswagen’s range of engines, powering many cars around the world from the T-Cross to the Passat Variant. Through continuous development, we have perfected the compact four cylinders. The result is a significant reduction in fuel consumption combined with extremely dynamic characteristics and quick responses”, says Thomas Ulbrich, Member of the Volkswagen Brand Management Board in charge of technical development.

As the name implies, the novelty is an evolution of the four-cylinder concern with a turbocharger, which is now more efficient thanks to the transmission of the three-way catalyst, now contained in a single unit with a particulate filter.

The unit can then manage emissions close to the engine, allowing VW to rely less on precious metals and prepare for stricter EU emissions standards later in the decade.

In addition, the unit has high-pressure fuel injection with a pressure of up to 350 bar, plasma surface treatment of cylinder work surfaces to reduce friction, and cooling channels in piston castings allowing for increased efficiency.

The novelty will be presented for the first time in the T-Roc and T-Roc Cabrio models with 150 horsepower. Later, however, Volkswagen will pair it with plug-in hybrid systems, which can be found, for example, in the Skoda Octavia RS iV, instead of the old 14-liter. Later, a similar engine will appear in the new generation Volkswagen Passat IV and the next generation Skoda Superb.
