Which U.S. carmaker is moving to capitalize on Volkswagen's diesel woes in the U.S. market? What did Tesla Motors CEO Elon Musk challenge us to do? (And when we did it, what did we conclude?) This is our look back at the Week In Reverse—right here at Green Car Reports—for the week ending on Friday, October 14, 2016. At the end of the... 
Today, we have the first photo of the Atieva Atvus electric car, the Audi R8 e-tron electric car ceases production, and we drive the updated 2017 Toyota Corolla compact sedan. All this and more on Green Car Reports. What will be the most unexpected thing about the Tesla Model 3? Our Twitter followers weighed in for our latest poll. A new hydrogen... 
The Toyota Corolla has been almost the default compact sedan among North American buyers for what seems like decades now. In good years, more than 350,000 are sold to retail and fleet buyers in the U.S., and they're part of the automotive landscape in even the reddest states of the union.

Carbon-dioxide (CO2) emissions from electricity generation during the first six months of 2016 were the lowest since 1991, according to the U.S. Energy Information Administration (EIA)... 
The Audi R8 e-tron—an all-electric version of the German automaker's R8 supercar—is no more. Less than two years after the production R8 e-tron was unveiled at the 2015 Geneva Motor Show, Audi plans to stop building the car. So ends one of the longest and most convoluted development stories of any new car in recent memory. CHECK OUT... 
Advocates of hydrogen fuel-cell cars are working to make their presence felt in much the same way that electric-car advocates have for years. Last Saturday was National Hydrogen and Fuel Cell Day. The specific date (10/08) was chosen in honor of hydrogen's atomic weight (1.008). Fuel provider Air Liquide used the celebration to launch a new...
