A new video shows the equipment the California Air Resources Board (CARB) used to determine that Volkswagen was cheating emissions tests. While the diesel vehicles tested fine on the dynamometer, CARB kept getting reports that showed a discrepancy in the real world. To test that, CARB used a portable generator for a power source and a lot of testing equipment inside the actual vehicle to get emissions readings on the road. This allowed them to show that there was indeed something different the car was doing to pass the lab tests. See the video above, and read more at Driving the Nation.

Tesla has done away with the 85-kWh battery option for the Model S in Canada. Now, in the Canadian version of the Tesla Design Studio configurator, customers can only select either the 70- or 90-kWh battery. This leads to some speculation about what Tesla will do next? Will Tesla release a 95- or 100-kWh battery soon at the top of the range? Could the entry level battery receive an increased capacity, as well? Perhaps Tesla also intends to do away with the rear-drive model altogether to help simplify production. Read more at Teslarati.

Tesla increased the number of Supercharger sites by about 50 percent around the world in the past year. As cool as the Model S is (and now, the Model X as well), Tesla strongly believes that building infrastructure for its customers is important for attracting new ones. In late February of 2015, Tesla celebrated 2,000 Supercharger plugs at 400 hundred sites throughout the US. 11 months later, there are currently 3,439 Superchargers at 593 sites in the US and Canada. Still, demand for those plugs is in high demand, as we saw during the holidays. Tesla continues to expand its charging infrastructure around the world as its model line grows and its presence spreads to more countries. Read more at Green Car Reports.
