Being based on the MQB platform, the B8 Passat has more interior space than the last generation model despite being shorter and lower than the last generation model. The front wheels were moved forward and the wheelbase extended by resulting in a shorter front overhang and a bigger cabin. The B8 Passat weighs less than the previous version by using vacuum-formed steel. It is offered with turbocharger-equipped engines ranging from 1.4 to 2.0 liters.
Driving assists
The B8 Passat is available with optional assistance systems including "Emergency Assist", "Traffic Jam Assist" and "Trailer Assist." Emergency Assist will attempt to reactivate the driver after steering feedback has not been detected for a period of time and will also transmit warning signals to its nearby surroundings. If the reactivation has failed, the vehicle will be stopped at a safe location. Traffic Jam Assist is capable of moving the vehicle in a traffic jam as long as the average speed does not exceed. Trailer Assist allows automatic parking with an attached tow trailer.

Powertrains
The B8 Passat was initially available with two TSI petrol and four TDI diesel powertrains that produce more power than their equivalents from the B7 without changing displacement. The 2.0 TDI engine is available in three configurations, with two being equipped with selective catalytic reduction catalysators to reduce the emission of nitrogen oxide. Every engine with the exception of the SCR-equipped 2.0 TDI engines is mated to a six-speed transmission with an optional a six-speed or seven-speed dual-clutch transmission. A 4Motion all-wheel drive drivetrain is available as standard for the strongest SCR TDI engine and optional for the weaker variant. Every engine is based on 4Motion/BlueMotion Technology and is turbocharged inline-four. In 2015, four additional petrol and two diesel engines became available. In 2015, Passat received two more powerful petrol engines, marketing it as Passat R-Line, which was however shortly thereafter discontinued.
UK sales began in mid-2015, with deliveries in October 2015. In the Netherlands, pre-orders were opened in early 2015 with deliveries in September 2015.
