Hyundai Genesis and Veloster (up 300+%) with staying power

Cadillac ATS (up 856%) 

 

This is a gauge of short-term effectiveness. Last year's Eminem ad for Chrysler was a long-term image building exercise which continued to pay dividends long after the Super Bowl and well beyond internet traffic.  So Edmunds' analysis shouldn't be read to suggest that ad, or others were failures.  Their success may need a different yardstick.

But it is interesting to see which ads were motivational, in addition to being hysterical.
