Today we look at the usefulness of Tesla's lone battery-swapping station, Toyota's claim that it can gradually lower the price of the Mirai fuel-cell car, and the 2017 Audi Q7 e-tron's switch from diesel to gasoline for the U.S. All this and more on Green Car Reports.

Diesel enthusiasts have been salivating over the 2017 Audi Q7 e-tron plug-in hybrid, but the previously-shown diesel engine will reportedly be swapped for a gasoline unit in the U.S. and China.

Toyota is recalling 2012 through 2014 model-year RAV4 EV electric crossovers to address a software glitch in a Tesla-supplied powertrain component.
