Video: Buick Invicta

General Motor's Buick brand is blossoming in China, so the automaker chose the largest Chinese Auto Show this year to unveil its latest concept: the Invicta. Unlike the Riviera concept shown in Shanghai last year, the Invicta is slated for production soon given the level of refinement we saw when we viewed the car in Beijing. And unlike some market-specific new cars unveiled at the show, the Invicta will make its way to other markets across the globe.

Mercedes-Benz G-class to get V12 power

Mercedes-Benz has slyly revealed a lightly facelifted version of the 33-year-old G-class prior to its planned public premiere at the Beijing motor show next month. The reworked version of the German carmaker's iconic military-grade SUV, planned to go on sale in European markets in June with North American deliveries slated to begin by the end of this year, can be seen in the background of an official photograph of the facelifted GLK posted on the Mercedes-Benz media Web site. Among the subtle changes made to the G-class's classic square exterior is a restyled grille with three prominent slats in place of the older model's seven slats, new headlamp inserts with horizontally mounted LED running lights and redesigned mirror housings.
