  A teardown analysis of the Volkswagen Passat (1.4L TSI Comfortline model for the Japanese market) was performed in September 2016 by the Hiroshima Industrial Promotion Organization. The Passat (the 8th-generation model: launched in 2014) received the 2015 European Car of the Year award for excellent driving performance, ride comfort, safety, and utility.

  The Passat is built on the MQB platform, which is also used by the 7th-generation Golf. The platform offers benefits including increased body rigidity and weight reduction that result in excellent dynamic performance, a comfortable ride, and cabin quietness. It is powered by a 1.4L direct injection single-turbocharger engine with a water-cooled intercooler, and delivers a maximum output of 110 kW (150 PS) and 250 Nm (25.5 kgm) of torque. Two of its four cylinders are left idle under low loads to achieve a JC08 mode fuel efficiency of 20.4 km/liter. This report focuses on the water-cooled intercooler, displacement management system, and other engine-related technologies that are featured on the Passat. The next report will focus on the body structure and other elements of the MQB platform.
