It was back in 1989 when Lexus shocked the luxury car establishment with the LS 400, which made its debut at the Detroit auto show. The launch heralded the birth of the Lexus brand, and the original LS made its mark by offering the performance, quietness and luxury that matched, if not bettered, its rivals from that era.

Fast forward 28 years and Lexus will reveal the all-new, fifth-generation LS flagship at the 2017 North American International Auto Show next month. It will be a “world-class car” for more than 90 countries around the globe, boasting a bold new look with a coupe-like silhouette. See Tokyo 2015’s Lexus LF-FC concept for clues.

Built on the company’s all-new global architecture for luxury vehicles (GA–L), the rear-wheel drive platform — an extended version of that used in the stunning LC coupe — will offer a more dynamic experience on the road, Lexus promises. A spacious cabin, luxurious appointments and visionary technology are also on Lexus’ cards. Main rivals: the Mercedes-Benz S-Class and BMW 7 Series.
