Since the disorganized Dieselgate, the Volkswagen Group has pledged to clean up its tainted image by channeling most of its efforts into electric vehicle development. The MEB platform serves as the backbone of the zero-emissions attack, with more advanced PPE arriving in 2023 for luxury Audi and Porsche products. It doesn’t really leave the good old combustion engine behind, as evidenced by the new gasoline units introduced today.
As the name implies, the 1.5 TSI evo2 is an evolution of the group’s 1.5 liter petrol engine. The turbocharged four-cylinder plant has been made more efficient by driving a three-way catalytic converter and gasoline particulate filter in a single emission control module mounted near the engine. Doing so has allowed VW to be less reliant on rare metals while allowing the company to be prepared for the tougher emissions regulations that are sure to arrive later this decade in Europe.
Officially dubbed “Active Cylinder Management,” the cylinder deactivation technology has now evolved into the ACTplus system. This offers a sleeker transition from four to two cylinders and vice versa. In addition, the operating range has been extended as the second and third cylinders do not start when the engine is operating at low and medium loads and speeds. VW promises “virtually invisible switching” to ensure smooth operation.
The 1.5 TSI evo2 was initially offered in the T-Roc and T-Roc Convertible with 150 horsepower. It will be added to other models, including a plug-in hybrid model with a combined output of 272 hp. Chances are the next-generation VW Passat and its equivalent Skoda Superb will get this PHEV powertrain once they debut sometime in 2023.
Even in a press release that talks about the new internal combustion engine, VW wants to remind us that the EV project will account for 70 percent of all sales by the end of the decade. Since a full switch to electricity won’t happen overnight, the remaining ICEs will be updated to meet Euro 7 regulations for selling cars in countries where ICE remains popular. The German automaker admits the charging infrastructure is not mature enough in some areas; hence why conventionally powered vehicles persist for the time being.
