Reports out of Europe also suggest that a new diesel engine could be on the cards, equipped with extreme high-pressure injectors and matched to a new ten-speed DSG auto.
The Passat R36 performer with six-cylinder power is also rumoured to be making a comeback, with the model again expected to feature all-wheel-drive.
New features are believed to include redesigned headlights, a slightly higher beltline and a longer wheelbase, aimed squarely at winning sales in the Chinese market.
Volkswagen introduced a light update to its Passat range in Australia around a year ago, bringing a more powerful entry-level diesel engine to the line-up.
Last month, Volkswagen sold 190 Passats in Australia, with prices for the current range starting at $44,490 plus on-roads for the Passat 130TDI Highline sedan.
The 2015 Frankfurt Motor Show is a logical possibility for the new Passat’s unveiling, ahead of a potential Australian arrival sometime in 2016 or 2017.
