The Cash for Clunkers program has given automakers a spike in their sales and while they’ve been reaping the rewards all to themselves, those who have been late to throw their hats on the program are finally doing so.

One car brand that has joined the fold is Audi,->ke14 which is now extending an extra $1,000 incentive for every car sold under the government-funded CARS program on top of the rebates the program gives away.

Audi’s program only covers a limited number of its models – 18 2008 and 2009 models, to be exact. The newer models are still being discussed as eligible vehicles, although some of them, including the Audi A5 2.0T, have yet to be included because the EPA hasn’t certified the car’s fuel efficiency rating.

Audi America’s CEO, Mark Del Rosso said that the CFC program is a great opportunity for Americans to get their hands on a new Audi, which, for some of us, just might be too good an offer to pass up. It’s not all the time when you can say that you’re this close to purchasing either an A3->ke1086, A4->ke1087, A4 Avant, A4 Cabrio, TT->ke1081 Coupe or Roadster, a Q5->ke1666 or many of their quattro variants. So when the opportunity presents itself, it’s something that’s definitely worth considering.

Continued after the jump.

To entice customers even further, the $1,000 incentive is only the tip of Audi’s promotional iceberg. Other incentives include a special 60-month APR and improved lease terms.

So if you fancy driving down America’s highways on a brand-new Audi, you have until August 31 to avail of the incentives. We must warn you, though. Promos like this usually dry up quicker than anybody thinks so if you’re thinking about getting an Audi, we suggest that you hurry and get in front of the line before supplies dry up.
