The Drive Smart Challenge
 

The Drive Smart Challenge is a new tips site that estimates your annual savings based on small changes to your car and how you drive.

Pretty interesting project with a lot of heavy backers (NASCAR is promoting it now). Looks like it outputs a bunch of tips similar to ours, but goes the added step of making guesses to how much annually you could save by increasing your MPG (making assumptions about your annual mileage).

It looks pretty good and we might present similar annual estimations instead of just suggested savings based on your next tank.
