The International Advertiser Bitch Slapping Awards (IABSA) have been announced this week and the finalists include three of the world's most prestigious automakers.

The trouble began when BMW released an ad for its new 3-series and congratulated Audi for winning the South African car of the Year award. Certainly an esteemed honor in it's own right, but BMW signed the congratulations with the line, "From the winner of the world car of the year award 2006." Ohhhh, snap!

Audi's PR guerrillas, not willing to sit idly by while being assaulted in the print realm, fought back with the ferocity expected from the German carmaker. They parried BMW's thrust with an ad proclaiming that the "world car of the year award" was nice, but we've kicked butt at LeMans for six consecutive years, so put that in your pipe and smoke it!

Then, from the east, comes Subaru, who wanted a piece of this chest-pounding, automotive aggression and jumped in with an ad proclaiming, "Well done to Audi and BMW for winning the beauty contest. From the winner of the 2006 International Engine of the Year Winner." Burn!

The full ads can be viewed in all their egregious glory after the jump.
