Jaguar is plotting new styling for 2017 that will be a big change for the brand's lineup.
Besides the rectangular grille that characterizes its current sedans, "everything else will change" on Jaguar's upcoming models, sources familiar with the matter told Edmunds.com.
The Jaguar XF will likely be manufactured with a lightweight aluminum body that will improve fuel economy. The upcoming sedan is tentatively slated to launch in the 2016 model year.
Car fans will be especially surprised to see the next Jaguar XJ, which "will be a bit of a jolt, but will work for people," a source told Edmunds.
The brand is additionally considering a new Jaguar crossover vehicle but has no official plans for now.
Jaguar is also looking into introducing a smaller car that would face off with the Audi A3 sedan and Mercedes-Benz CLA-Class.
Expected to arrive in U.S. showrooms sometime in 2016, the new Jaguar XE compact sedan debuted earlier this month.
While the Jaguar brand is usually associated with wealthy men in their later years, the new XE is designed with women and younger drivers in mind.
"We think the customers are likely to be younger, earlier in their life stage, they are more likely to have children ... they are more likely to be female," Nick Miller, chief program engineer of the XE series, told Reuters.
Built in the "Saloon" style, the XE sedan is Jaguar's cheapest model yet at $44,000 and should go on sale next year, according to Bloomberg News.
The XE sedan, which will likely be followed by an SUV model, will be featured at next month's Paris Motor Show.
