With generous interior space, responsive handling, and a comfortable, quiet ride, the Passat is a competitive midsized sedan. The primary powertrain is an energetic 1.8-liter turbo four-cylinder and a six-speed automatic. High-end versions use a powerful 3.6-liter V6. The 1.8-liter turbo averaged a very good 28 mpg overall and 39 on the highway. Front seats are very accommodating. Extra-spacious rear seats are a big plus, and the trunk is huge. For 2016 VW added USB ports, improved interior fit and finish, and introduced new active safety features. Reliability has been average. The diesel version is under investigation by the EPA for not complying with emissions regulations.
