Those two are understood to represent two of three new concepts that preview the brand's new styling direction, but the identity of the third showcar remains a mystery.
That could be about to change, however, with reports out of China this week suggesting the next model will be a long-overdue replacement for the big S80 sedan.
According to website CarNewsChina, Volvo and Geely boss Li Shufu has reportedly confirmed plans for a new flagship sedan, designed to compete with the likes of the BMW 7 Series, Mercedes S-Class and Audi A8.
The report adds that the new model, expected to be dubbed S100, will be both larger and more upmarket than the current S80, packed with features to rival its German rivals.
Like the big XC90 SUV, the S100 would ride on a stretched version of Volvo's new SPA platform, which is expected to see all models weigh around 100 to 150kg less than their predecessors.
The company's new four-cylinder Drive-E engines would likely also feature, and the S100 will undoudtedly benefit from a hybrid setup for more power in up-spec models.
Production is expected to occur in China, at Volvo's Chengdu plant.
For now, the ageing second-generation S80 is expected to soldier on, although one last major update could appear before the all-new model appears in 2014.
