While it's hard to believe, we are about done with 2013. As we head into the new year we wanted to take a moment to look back at all of the awesome stuff we've seen over the past 12 months. Here's a quick recap:

This year there were quite a few awesome videos of unique vehicles hitting the dyno. Why, just this week, we saw the crazy twin-turbocharged Mercedes-Benz SLS AMG spitting massive flames while doing a dyno run. There was also this Chevrolet Camaro that went 200 mph on the dyno before blowing up its tires. The most epic dyno video this year had to be of the 2,282-horsepower twin-turbocharged Saleen S7.

As for tiny engines, we had quite a few to write about this year. First there was this tiny yet awesome V-8 engine. Then there was the world's smallest V-12 engine, which is obviously the ultimate desk toy.

If tiny engines aren't your thing, we were pretty enamored with the Mercedes-Benz V-12 engine that was hand-built from bone and wood.

One of the largest vehicle reveals this year was definitely the new 2015 Ford Mustang. Love it or hate it, it's definitely a different direction for the legendary pony car, with an independent rear suspension and turbocharged four-cylinder engine option; the new Mustang is sure to be a jolt to the system for car enthusiasts.

While we've only touched a portion of the awesome stuff we posted in 2013, we want to hear from you. What were your favorite posts that we hit on social media this year? Did you see it on our Facebook fan page or Twitter stream?
