100. Toyota

A brand built on turbo-charged performance and the most reliable family cars on the market gave up its performance roots to focus on environmentally friendly family cars in the 2000s (they also brought forth Scion, but we're not going to talk about that here). Going after the middle paid off- Toyota is now the world's largest automaker. It's also viewed as the greenest, thanks to the Prius. This car's quirky styling and awesome gas mileage has become the face of green motoring worldwide.
