Nissan has plenty to be proud of with its all-new 2013 Altima. The sedan promises to average 38 miles per gallon on the highway, which is best-in-class for a non-hybrid. The new Altima also boasts a lighter and stronger frame, increased power and quicker acceleration among its many improvements.

As you'll see below, crafting an ad campaign is that much easier when you have so much to be proud of. Scroll down to watch the first four commercials that Nissan has lined up to introduce its new Altima to America.

In the first two, Nissan plays it straight with a raft of back-patting and a couple of jabs at the competition from Honda and Toyota. The second two spots aim for the funny bone while also pointing out new technology and hammering away at those all-important fuel economy numbers.

We're especially fond of the last commercial, which cleverly points out that the horn will honk when the tires have been filled to the optimum level. Funny stuff.
