Google has just added some really good information to their knowledge graph for those that are looking for a new car. So if you're looking for information on say a Chevy Malibu, as I did in the screenshot shown above. Google will give you the Gas mileage, the price of the car as well as horsepower, make, other model years, and configurations. Of course the most important part these days is the gas mileage. But this makes it much easier then trying to find the information on Chevrolet's website. Although it appears that it doesn't work for every car, as I searched for Chevy Aveo and it didn't show up with the card on the right. But it's also worth noting that you don't even need make sometimes.
For instance, I searched for "2013 fusio" (I mispelled it on purpose) and it still found the knowledge for the 2013 Ford Fusion. So it appears that the more popular cars, it finds the information without knowing the make, which is pretty cool. And those wondering, the Ford Fusion gets about 25 MPG city and 37 MPG Highway. I know you're all wondering that.
While the information isn't super comprehensive right now, I'm sure Google will get more information soon and inject it into their search results. Since that's their primary source of revenue (thanks to ads), they are always working to make searching better, and easier. You can find out more information about this update from Google's official Google+ page. However there is some bad news. Google states that this is only available on google.com in the US. So like many of their other great products, it's only in the US, at least for now. Hopefully this changes quickly, as I'm sure our friends outside the US would love to see this information added to Google Search.
