Beginning on Tuesday, June 24, General Motors will begin a zero percent financing program while concurrently raising prices for the 2009 models approximately 3.5 percent.

In other decisions, the company has enlisted the aid of Citibank to determine the future of the Hummer brand while boosting its production of compact models, mid-sized cars, and crossovers.

Additionally, from June 24 through June 30, a "72 Hour Sale" with zero percent financing for 72 months will be offered in an effort to boost flagging sales. The sale includes all trucks and large SUVs and some smaller SUV models, but does not include the Buick Enclave, GMC Acadia, or Saturn Outlook, all crossovers.

GM Vice President of Vehicle Sales, Mark Laneve said, "We know how to do this, we throw considerable media weight behind it. It's a really simple offer that's very compelling. It's a good way to finance if someone's upside down on their vehicles."

In a separate announcement, the company said it would reduce its truck and SUV production by another 170,000 units during the second half of the year, with increased attention on the production of cars and crossovers by as many as 47,000 units. Crossover production will be increased by 3,500 for the GMC Acadia and 7,000 for the Buick Enclave.

Options for the Hummer brand could include re-conceptualizing the product with an eye toward greater fuel efficiency or selling or leasing the brand.
