With a number of upgrades and changes for the 2018 model year, Volkswagen is making its Passat mid-sized sedan available in six trim levels including the base S version, R-Line, SE, SE with Technology, GT, and SEL Premium. Replacing the 1.8-liter four-cylinder turbocharged engine, Passat's new base powertrain features the most advanced 2.0-liter four-cylinder TSI engine it has ever offered.
