This vehicle has a single powertrain option: a 174-horsepower turbocharged 2.0-liter four-cylinder engine paired with a six-speed automatic transmission. Drivers find this powertrain option to be smooth and powerful, though this vehicle is certainly no sports car.
This is pretty standard for mid-size sedans like the Passat — anything above a four-cylinder engine would be overkill. Because of its size, it just doesn’t need anything more powerful to move around, and anything bigger would significantly affect its gas mileage. That’s why the bigger six- and eight-cylinder engines are generally left to bigger sedans, trucks, and SUVs.
