Regardless of which 2019 Jetta trim level you may choose, a few things remain unchanged. For instance, every model hosts a turbocharged 1.4-liter engine with 147 horsepower and 184 pound-feet of torque beneath its hood. Similarly, all 2019 models are expected to earn quality fuel economy with EPA estimates of up to 30-city mpg, 40-highway mpg, and 34-combined mpg.
