Rolls-Royce has entered the SUV race with a new model called the Cullinan. It starts almost $100k above the rival Bentley Bentayga and could quite possibly become the British brand's most popular model. After driving one in Wyoming, we now know why.

Can't wait for Porsche to build a hybrid 911? Well, there's an aftermarket kit being developed that will let you build your own. It will cost about $75,000 and add 175 extra horses.

BMW engineers are out testing an updated version of the X1. The compact crossover SUV will receive a sharper look and hopefully a few chassis mods, too. It also looks like a plug-in hybrid option will be available.
