Volkswagen Passat and Audi, both being part of the Volkswagen Group, offer a range of turbine machines (engines) depending on the specific model and generation. The turbine machines used in these vehicles are commonly referred to as "turbocharged" engines. Turbocharging is a method used to increase an engine's power output by forcing more air into the combustion chamber.

Here are some examples of popular turbine machines used in Volkswagen Passat and Audi vehicles:

2.0 TSI/TFSI: This is a 2.0-liter, four-cylinder turbocharged engine commonly found in various Volkswagen and Audi models. It utilizes direct fuel injection and a turbocharger to deliver a balance of power and efficiency.

1.8 TSI/TFSI: Another popular choice, the 1.8-liter turbocharged engine, is often found in smaller Volkswagen and Audi vehicles. It offers a good balance between performance and fuel economy.

3.0 TDI: This engine is a 3.0-liter V6 turbodiesel, commonly used in certain Audi models. It combines the benefits of turbocharging with diesel fuel efficiency and torque.

2.0 TDI: The 2.0-liter four-cylinder turbodiesel engine is a popular choice in both Audi and Volkswagen vehicles. It offers good fuel economy along with sufficient power.

3.6 VR6: The 3.6-liter VR6 engine is a naturally aspirated (non-turbo) V6 engine used in some Volkswagen and Audi models. However, depending on the specific model and generation, turbocharged variants of the VR6 engine might also be available.

It's important to note that the availability of specific turbine machines can vary depending on the market, model year, and vehicle trim level.
