As the year starts drawing to a close, Volkswagen is busy preparing an all-new generation of one of their best-sellers. The German automaker has quietly previewed the next-generation Jetta through the marque's Canadian website and its debut date has set for next year's North American International Motor Show.

The teaser Volkswagen has shown is in the form of a GIF image, showing small sections of the sedan's rear quarters. From the image, one can see slim tail lights and a defined character line striking through the door handles. Its headlights meanwhile appear to be larger than those seen in the current model and a small part of the grill is seen, showing off a bolder design.

With its general shape revealed, it could be said that Volkswagen will apply a more evolutionary redesign rather than a revolutionary make over. The rear part of the car shows that Volkswagen is bucking the trend of liftback-like rear windshields of its all-new competitors and has a more formal and upright roofline.

For its seventh iteration, the 2019 Jetta will ride on the latest version of the MQB platform, utilized in a significant number of Volkswagen Auto Group products. This also means that the Jetta will be underpinning the next-generation Golf hatchback, along with other front-wheel drive cars from Skoda, SEAT and select Audi models.

Engine range has yet to be confirmed but do expect the new 1.5 TSI and redesigned 2.0 TDI engines to power the Jetta. It is also possible that the mild-hybrid system Volkswagen is currently testing will make its way under the Jetta's hood. A high-performance GLI version may be launched months after the non-sporting variants make their way to North American dealerships by mid-2018. It has yet to be determined when the seventh-generation Volkswagen Jetta will arrive in Asia.
