Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.
Fans of green cars are eagerly awaiting the release of the Tesla Model X, but you won't have to wait to see what it looks like on the road -- a YouTube user spotted the new car cruising down the freeway in Palo Alto, California. The electric vehicle, which was originally supposed to be released in 2013, is now set to launch in the third quarter of 2015. In other automotive news, Mercedes-Benz has announced plans to release 10 new plug-in hybrid models by 2017. The new models will be designated with a simple "e" instead of the longer "plug-in hybrid" branding. Toyota is currently testing its i-Road three-wheeled electric vehicle in France. The i-Road is seen as a "last-mile" vehicle, and Toyota wants to see how it can integrate with public transportation to decrease traffic gridlock.
