Acura's top-selling RDX is set to come in for an update. The small SUV is about to reach the midway point in its life cycle and a prototype for an updated version has been spotted.

Another vehicle out testing is the next-generation SL Roadster. It's being developed by Mercedes-Benz AMG and will offer all-wheel drive for the first time.

One of only 45 Ford GT Mk II supercars destined to be built is headed for auction. This is the lighter, more powerful track-only version of Ford's GT supercar, which was unveiled in 2019 with a starting price of $1.2 million.
