Ever since India's Tata Motors (NYSE:TTM) bought Jaguar from Ford (NYSE:F) a few years ago, one big question has gone unanswered: Would Tata really be willing and able to spend the money needed to turn Jaguar into a credible rival to the likes of BMW (NASDAQOTH:BAMXF) and Audi?

This past week at the Frankfurt Motor Show, Jaguar showed off part of the answer: A new platform that will underpin a host of new Jaguars, including a serious rival to BMW's 3-Series and Audi's A4. As Fool contributor John Rosevear explains in this video, that's a crucial move for Jaguar -- and the surprising crossover SUV shown above could turn out to be just as important.
